Study shows how plants regulate the climate in Europe

Based on a media release of Martin Luther University Halle-Wittenberg The climate regulates plant growth, but the climate is also regulated by plants. Depending on the vegetation composition, ecosystems even have a strong influence on the climate in Europe, a study by Martin Luther University Halle-Wittenberg (MLU) and the German Centre for Integrative Biodiversity Research (iDiv) in the journal Global Change Biology shows. The researchers linked satellite data with around 50,000 vegetation records from across Europe. A good five per cent of regional climate regulation can be explained by local plant diversity. The analysis also shows that the effects depend on many other factors. Plants regulate the climate by reflecting sunlight or cooling their surroundings through evaporation.

Fish in the upper Danube could be just as endangered in the future as they were in the past, but for different reasons

Based on a media release from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) Rivers belong to the most threatened ecosystems on Earth. While many studies have projected climate change effects on species, little is known about the severity of these changes compared to historical alterations. Researchers led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) and the German Centre for Integrative Biodiversity Research (iDiv) explored the vulnerability of 48 native fish species in the upper Danube River Basin to past and potential future environmental changes. They show that fish have been particularly sensitive to changes in flow regimes in the past, while higher temperatures will pose the greatest threat in the future. The threat assessment will remain at least as high in the future. However, it could probably be mitigated by reconnecting former floodplains and improving river connectivity.

Leipzig. Insect decline is being driven by losses among the locally more common species, according to a new study published in Nature. Led by researchers at the German Centre for Integrative Biodiversity Research (iDiv) and the Martin Luther University Halle-Wittenberg (MLU), the meta-analysis of 923 locations around the world notes two significant trends: 1) the species with the most individuals (the highest abundance) are disproportionately decreasing in number, and 2) no other species have increased to the high numbers previously seen. This likely explains the frequent observation that there are fewer insects around now than ten, twenty, or thirty years ago.

How forests smell – a risk for the climate?

Based on a media release of Leipzig University Plants emit odours for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers from Leipzig University, the Leibniz Institute for Tropospheric Research (TROPOS) and the German Centre for Integrative Biodiversity Research (iDiv) carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. In the past, it was assumed that forests with more species would release more emissions. Experiments by the Leipzig team have now disproved this assumption. Their study has been published in the journal Communications Earth & Environment.

Halle/Saale, Fort Lauderdale. More than 100 years of observations in nature have revealed a universal pattern of species abundances: Most species are rare but not very rare, and only a few species are very common.

New map on potentially groundwater-dependent vegetation in the Mediterranean biome

Report by Léonard El-Hokayem, doctoral student at Martin Luther University Halle-Wittenberg and the German Centre for Integrative Biodiversity Research (iDiv) Halle. Decreasing rainfall and increased groundwater use are threatening vegetation and ultimately biodiversity in the Mediterranean biome. Plants that depend on groundwater are particularly vulnerable. We have developed a novel, easy-to-use index to map potentially groundwater dependent vegetation (pGDV) based on environmental site conditions and vegetation characteristics. Our concept combines globally-available geodata and remote sensing and has recently been published in Science of The Total Environment. The results indicate that 31 % of the natural vegetation in the Mediterranean likely depends on groundwater. A biome-wise map of pGDV is important to prioritise areas for detailed identification of actual GDV and biodiversity conservation.

Diverse landscapes help insects cope with heat stress

Leipzig/Jena/Bad Lauchstädt. Global warming is affecting terrestrial insects in multiple ways. In response to increasingly frequent heat extremes, they have to either reduce their activity or seek shelter in more suitable microhabitats. A new study led by researchers from the German Centre for Integrative Biodiversity Research (iDiv) and Friedrich Schiller University Jena shows: The more diverse these microhabitats are, the better for the insects. For their study, published in Global Change Biology, they developed a new approach to accurately track insect movements and activity.

Widespread species gaining ground

Leipzig/Halle. Human activities are accelerating biodiversity change and promoting a rapid turnover in species composition. A team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv) and Martin Luther University Halle-Wittenberg (MLU) has now shown that more widespread species tend to benefit from anthropogenic changes and increase the number of sites they occupy, whereas more narrowly distributed species decrease. Their results, which were published in Nature Communications, are based on an extensive dataset of over 200 studies and provide evidence that habitat protection can mitigate some effects of biodiversity change and reduce the systematic decrease of small-ranged species.

How fishermen benefit from reversing evolution of cod

Leipzig. Intense fishing and overexploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. The new study by researchers from the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University and the Institute of Marine Research in Tromsø, which was published in Nature Sustainability, shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.

Dwarfs and giants on islands more likely to go extinct

Leipzig/Halle. Islands are “laboratories of evolution” and home to animal species with many unique features, including dwarfs that evolved to very small sizes compared to their mainland relatives, and giants that evolved to large sizes. A team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv) and Martin Luther University Halle-Wittenberg (MLU) has now found that species that evolved to more extreme body sizes compared to their mainland relatives have a higher risk of extinction than those that evolved to less extreme sizes. Their study, which was published in Science, also shows that extinction rates of mammals on islands worldwide increased significantly after the arrival of modern humans.

Global climate data insufficiently explain composition of local plant species

Based on a media release of Martin Luther University Halle-Wittenberg The global climate influences regional plant growth – but not to the same extent in all habitats. This finding was made by geobotanists at Martin Luther University Halle-Wittenberg (MLU) and members of the German Centre for Integrative Biodiversity Research (iDiv) after analysing over 300,000 European vegetation plots. Their conclusion: No general prediction can be made about the effects of climate change on the Earth’s vegetation; instead, the effects depend to a large degree on local conditions and the habitat under investigation. The findings were published in the renowned journal Nature Communications.

Plant roots fuel tropical soil animal communities

Based on a media release by the University of Göttingen Göttingen/Leipzig. Soil animal communities in the tropics are driven by plant roots and the resources derived from them. This is the main finding of a new study of a research team led by the University of Göttingen, the German Centre for Integrative Biodiversity Research (iDiv) and Leipzig University. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it has been believed that leaf litter is the primary resource for these animals. However, this recent study published in the journal Ecology Letters shows that litter doesn’t play any crucial role at all for the tropical soil fauna.

How could we evolve such a huge brain?

Based on a media release by the University of Amsterdam Amsterdam/Leipzig/Jena. A new study, published in the journal Frontiers in Ecology and Evolution, investigated the foraging behaviour of children in a present-day forager society. Already from an early age, there was a gender-specific development of foraging skills. These new findings, combined with the high level of food sharing in forager societies, support the embodied capital theory, offering an explanation for the substantially larger brains in humans. Foraging skills could have provided humans with a more stable energy and nutrient supply, which may ultimately have enabled large resource investments into the brain. The research was led by the University of Amsterdam (UvA), the German Centre for Integrative Biodiversity Research (iDiv), the Max Planck Institute for Evolutionary Anthropology, the Helmholtz Centre for Environmental Research (UFZ), and the Friedrich Schiller University Jena.

Plant diversity may never fully recover from agriculture without a helping hand

Leipzig/Minnesota. Agriculture is considered a major disturbance for ecological systems – the recovery of degraded or formally used agricultural land might take a long time. However, without any active restoration interventions, this recovery can take an exceedingly long time and is often incomplete, as shown by a team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz Centre for Environmental Research (UFZ). Their study, which was published in the Journal of Ecology, sheds light on the recovery process at different scales in former agricultural sites, pointing to specific restoration interventions that could help biodiversity to recovery.

Grassland ecosystems become more resilient with age

Based on a media release of the University of Zurich Zurich/Leipzig. Recent experiments have shown that the loss of species from a plant community can reduce ecosystem functions and services such as productivity, carbon storage and soil health. With the loss of functioning the ecosystem may also become destabilized in its ability to maintain ecosystem functions and services in the long-term. However, assessing this is only possible if experiments can be maintained for a sufficient length of time.

wildE: Restoring wild habitats in Europe against climate change

Based on a media release by INRAE  Cestas/Halle. Terrestrial ecosystems throughout Europe face the twin threats of climate change and the loss of biodiversity. “Rewilding” could be an important ecological restoration solution to mitigate both of these issues, but up to now, it is mostly restricted to local initiatives scattered across the continent focussing on biodiversity objectives alone. The wildE project aims to assess the synergies between climate change mitigation, adaptation and biodiversity and thus to improve the potential of climate-smart rewilding as a nature-based solution for ecological restoration in Europe. wildE is funded by the EU Horizon programme and coordinated by the French National Research Institute for Agriculture, Food and Environment INRAE with the participation of the German Centre for Integrative Biodiversity Research (iDiv) and the Martin Luther University Halle-Wittenberg.

Identification of groundwater-dependent vegetation via satellites

Report by Léonard El-Hokayem (doctoral researcher at MLU and iDiv) Halle. Groundwater in (semi)-arid regions plays a key role in sustaining important terrestrial ecosystems, providing drinking water and supporting agriculture. We developed a new multi-instrument framework to identify groundwater-dependent vegetation (GDV) in these regions. Therefore, a combination of satellite images and other environmental data got tested and validated in a Mediterranean study area in Southern Italy. The developed concept was recently published in Ecological Indicators. It allows for the identification and study of vegetation that relies on groundwater, and thus can help protect these biodiversity hotspots and the ecosystem services they provide.

Deforestation and grassland conversion are the biggest causes of biodiversity loss

Based on a media release by Natural History Museum London Luxembourg/London/Halle. The conversion of natural forests and grasslands to agriculture and livestock is the biggest cause of global biodiversity loss. The next biggest drivers are the exploitation of wildlife through fishing, logging, trade and hunting – and then pollution. Climate change ranks fourth on land so far but second in oceans. This is the main result of an international study led by researchers from Universidad Nacional de Córdoba (UNC) in Argentina, Helmholtz Centre for Environmental Research (UFZ), German Centre for Integrative Biodiversity Research (iDiv) and the Natural History Museum London. The study, published in Science Advances, demonstrates that fighting climate change alone will not be enough to prevent the further loss of biodiversity.

More yield, fewer species: How human nutrient inputs alter grasslands

Leipzig. With high nutrient inputs in grasslands, more plant species get lost over longer periods of time than new ones can establish. In addition, fewer new species settle than under natural nutrient availability. With a worldwide experiment, researchers led by the German Centre for Integrative Biodiversity Research (iDiv), the Helmholtz Centre for Environmental Research (UFZ) and the Martin Luther University Halle-Wittenberg (MLU) have now been able to show why additional nutrient inputs reduce plant diversity in grasslands. Another finding was that the increase in biomass with nutrient inputs is due to a few plant species that can use higher nutrient inputs to their advantage and remain successfully at a site over long periods of time. The results have been published in the journal Ecology Letters.

Global study: Few of the ecologically most valuable soils are protected

Halle, Leipzig, Seville. Current protected areas only poorly cover the places most relevant for conserving soil ecological values. This is the conclusion of a new study published in the journal Nature. To assess global hotspots for preserving soil ecological values, an international team of scientists measured different dimensions of soil biodiversity (local species richness and uniqueness) and ecosystem services (like water regulation or carbon storage). They found that these dimensions peaked in contrasting regions of the world. For instance, temperate ecosystems showed higher local soil biodiversity (species richness), while colder ecosystems were identified as hotspots of soil ecosystem services. In addition, the results suggest that tropical and arid ecosystems hold the most unique communities of soil organisms. Soil ecological values are often overlooked in nature conservation management and policy decisions; the new study, published in Nature, demonstrates where efforts to protect them are needed most.

Informing future conservation priorities of ecosystems in the Tropical Andes

Joint press release by iDiv and NatureServe Washington D.C./Leipzig. Only about 5% of ecosystems within the Tropical Andes biodiversity hotspot are adequately represented in designated protected areas. Representation may be determined by a series of targets proposed by the Convention on Biological Diversity (CBD), which states at least 30% of land and waters in each country should be conserved. Protecting the full diversity of ecosystems reduces extinction risk for the species those ecosystems support, but very few places on the planet currently meet the CBD target. There is an opportunity to increase representation of ecosystems that meet the CBD target to 31% (39 ecosystem types total) across four Andean countries (Bolivia, Colombia, Ecuador, and Peru) through the additional protection by governments and civil societies of Key Biodiversity Areas (KBAs), places that meet the internationally recognized standard for sites that significantly contribute to the global persistence of biodiversity. This conclusion is shown in a new study led by NatureServe, the German Centre for Integrative Biodiversity Research (iDiv), and the Martin Luther University Halle-Wittenberg (MLU), together with other institutions throughout the U.S., Europe, and South America. The study, now published in the journal Remote Sensing, demonstrates how Essential Biodiversity Variables (EBVs) coupled with KBAs can inform conservation decisions at multiple scales.

The Gollum effect and its impacts on the scientific community

Report by Dr Jose Valdez, Postdoctoral Researcher of the Biodiversity Conservation research group at iDiv and Leipzig University, and senior author of a new publication in Frontiers in Ecology and Evolution While scientific research is becoming increasingly more collaborative, the ability to freely conduct research remains restricted by established researchers who feel they have the sole right to study specific study sites, model organisms, research topics, and sometimes even entire scientific fields. Like Gollum from The Lord of the Rings, they become possessively attached and guard these aspects of their research. In our recent publication in Frontiers in Ecology and Evolution we refer to this as the ‘Gollum effect’ and explore ways in which this can be overcome to promote scientific openness and lead science into a new era where it is dispensed fairly instead of at the hands of a selected few.

What doesn’t kill you makes you stronger

Based on a media release by the University of Zurich Zurich, Leipzig. The exposure to drought during previous generations in the field increases complementarity between offspring of different grassland species and thus makes them more resilient to subsequent drought. An international research team led by the University of Zurich and with the participation of the German Centre for integrative Biodiversity research and Leipzig University has revealed this transgenerational effect with about 1000 experimental plant communities in pots. The results, published in Nature Communications, suggest that if past extreme climatic events do not completely exclude species, they may enhance the sustainability of biodiversity and ecosystem functioning in a future with more frequent extreme events.

Heat-lovers are the lucky ones

Based on a media release from the Technical University of Munich (TUM) Munich/Leipzig. Heat-loving insect species in Germany are benefiting from global warming. The trends of different insect groups vary considerably. While the populations of butterflies and grasshoppers decreased more frequently than they increased, dragonflies showed predominantly positive trends. This is the conclusion of a new study led by the Technical University of Munich (TUM), the German Centre for Integrative Biodiversity Research (iDiv) and the Friedrich Schiller University Jena. In order to close significant data gaps, the research team evaluated an extensive collection of previously little-used data on over 200 insect species in Bavaria since 1980. The study was published in Global Change Biology.

Dinosaur extinction changed plant evolution

Leipzig, Amsterdam, Zurich. The absence of large herbivores after the extinction of the dinosaurs changed the evolution of plants. The 25 million years of large herbivore absence slowed down the evolution of new plant species. Defensive features such as spines regressed and fruit sizes increased. The research led by the German Centre for Integrative Biodiversity Research (iDiv) and Leipzig University has demonstrated this using palm trees as a model system. The researchers were also able to show how profound the changes were: Even the reappearance of large herbivores millions of years later could only partially overwrite the changes that had already taken place. The study has been published in the journal Proceedings of the Royal Society B. It provides a view of the geological past and, at the same time, promotes a better understanding of the consequences of current extinction processes.

While some insects are declining, others might be thriving

Leipzig/Halle/Jena. Observations of abundance changes in one group of insects– for example grasshoppers – say very little about how other types of insects, such as flies, are doing, even in the same place. This is because different groups of insects may show similar trends in one place, but dissimilar trends in other places. These are the findings of a new meta-study systematically examining long-term data on insects from more than 900 locations worldwide. The study, published in Biology Letters, was led by a team of researchers from the German Centre for Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU), the Friedrich Schiller University Jena and the Helmholtz Centre for Environmental Research (UFZ). It highlights the importance of monitoring multiple groups of species simultaneously to provide guidelines for conservation policies.

Trees call for help from birds and predatory insects

Leipzig/Jena. Trees emit scents when attacked by caterpillars and other herbivores. They use these to attract predatory insects and even birds, thus getting rid of their pests. This had only been demonstrated in smaller-scale experiments so far. A team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv), the Friedrich Schiller University Jena and Leipzig University has now demonstrated this phenomenon for the first time in a natural habitat – in the 40-metre-high canopy of the Leipzig floodplain forest. The chemical calls for help are so effective that they significantly determine the composition of the insect community in the canopy. This knowledge could be used for future natural pest control in agriculture and forestry, the researchers write in the journal Ecology Letters.

How to use ecosystem services in social-ecological networks

Leipzig. Social-ecological networks (SEN) have recently been proposed as a promising approach to conceptualise and analyse interactions and outcomes in social-ecological systems. In a social system, networks represent interactions between actors, such as knowledge exchange, trust, collaboration, which influence governance effectiveness. In ecology, networks depict biological nodes (e.g. species, patches) and processes that connect them (e.g., predation, landscape connectivity). Despite similarities in the approaches applied in both social sciences and ecology, these areas have developed largely in parallel without capitalising on their complementarity. As a result, there is limited integration of social and ecological theories, inclusion of ecological complexity in governance research, and vice versa. Building from different disciplines, in our new article in Trends in Ecology & Evolution we propose a typology to represent ecosystem service in SENs and identify opportunities and challenges of using SENs in ecosystem service research.

Extreme droughts also afflicting the Leipzig floodplain forest

Leipzig. The Leipzig floodplain forest was not equipped to endure two consecutive hotter drought years. Although the trees were able to partially cope with the 2018 drought, the accumulated and ongoing damage from drought stress caused their growth to collapse in the second drought year 2019. Depending on the tree species, this decrease in growth ranged from 9% to 42% when compared to climatically normal years. This is the result of a study published by a team led by the German Centre for Integrative Biodiversity Research (iDiv) in the journal Global Change Biology. The study may enable better understanding and prediction of how forests respond to climate change.

Sensational discovery in the Leipzig floodplain forest

Based on a media release by the Leipzig University Leipzig. Researchers and biology students from the University of Leipzig have discovered an extremely rare insect during a zoological field trip in the Leipzig floodplain forest: Bittacus hageni, belonging to the order of scorpionflies. The researchers caught several specimens in the leaf canopy of the Leipzig floodplain forest. This species is only found in very few places in Europe. In Germany, it was considered extinct until 2003. The find, which the researchers describe in the journal Entomologische Nachrichten und Berichte, highlights the importance of the Leipzig floodplain forest as a unique but endangered habitat. But it also proves the importance of student excursions to make valuable discoveries possible.

Based on a media release by Wageningen University Wageningen/Leipzig. Tropical forests are vanishing at an alarming rate through deforestation, but also have the potential to regrow naturally on abandoned lands. A study published this week in Science shows that regrowing tropical forests recover surprisingly fast. After 20 years, characteristic attributes have recovered by an average of nearly 80% of old-growth forest values. This applies e.g. to soil fertility, soil carbon storage, tree diversity, plant functioning and forest structure.

Functioning of terrestrial ecosystems is governed by three main factors

Based on a media release by the Max Planck Institute for Biogeochemistry (MPI BGC)  Jena. Ecosystems provide multiple services for humans. However, these services depend on basic ecosystem functions which are shaped by natural conditions like climate and species composition, and human interventions. A large international research team, led by the Max Planck Institute for Biogeochemistry (MPI BGC), and the German Centre for Integrative Biodiversity Research (iDiv), identified three key indicators that together summarise the integrative function of terrestrial ecosystems: The first is the capacity to maximise primary productivity, the second is the efficiency of using water, and the third is the efficiency of using carbon. The monitoring of these key indicators will allow a description of ecosystem function that shapes the ability to adapt, survive and thrive in response to climatic and environmental changes. The study was recently published in the journal Nature.

Survival strategy of starving spruces trees: the critical role of reserves

Based on a media release from the Max Planck Institute for Biogeochemistry Young spruce trees build up nutrient reserves even during long periods of famine. This is what scientists from the Max Planck Institute for Biogeochemistry (BGC), the German Centre for Integrative Biodiversity Research (iDiv), the Friedrich Schiller University of Jena (FSU) and other institutions have discovered. They manage to do this even when the energy supply through photosynthesis is paralysed in the long term, as in the case of climate extremes, for example by stopping their growth and even obtaining energy through self-digestion. Until now, it was assumed that this was only possible if enough photosynthesis products were available and growth processes were covered. The study has now been published in the journal PNAS. The knowledge can be used to improve models that predict the fate of forests against the background of climate change.

Coastal Ecosystems Worldwide: Billion-dollar Carbon Reservoirs

Based on a media release by the Kiel Institute for the World Economy (IfW Kiel) Kiel/Leipzig. Coastal ecosystems such as seagrass meadows, salt marshes and mangrove forests are valuable to humans in many ways. In particular, they store carbon – and do so with a much higher surface density than forests, for example. They thus make an important contribution to mitigating climate change. Australia’s coastal ecosystems alone, which absorb a particularly large amount of CO2 from the atmosphere, save the rest of the world climate-related costs of around 23 billion US dollar a year. This is according to calculations just published in Nature Climate Change by researchers at the Kiel Institute for the World Economy (IfW Kiel), GEOMAR Helmholtz-Centre for Ocean Research Kiel, the Universities of Kiel and Leipzig (UL) and the German Centre for Integrative Biodiversity Research (iDiv).

Dragonflies: Species losses and gains in Germany

Leipzig/Jena. Over the past 35 years, there have been large shifts in the distributions of many dragonfly and damselfly species in Germany. Many species of standing water habitats have declined, probably due to loss of habitat. On the other hand, running-water species, living in rivers and creeks, and warm-adapted species have benefited from improved water quality and warmer temperatures. This was found by a team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv), the Friedrich Schiller University Jena (FSU) and the Helmholtz Centre for Environmental Research (UFZ). The study, published in Diversity and Distributions, highlights the importance of citizen science and natural history societies for long-term data collection and nature conservation efforts for improving biodiversity.

Climate change, biodiversity loss and social justice – these challenges can only be overcome together

Based on a media release by Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) and Helmholtz-Centre for Environmental Research (UFZ) Kiel/Leipzig. The fight against global warming and for sustainable development can only succeed if, from now on, humankind considers the issues of climate change, biodiversity loss and social justice together, and takes them into account equally in all political decisions – globally, nationally and regionally – as well as their interactions. According to the German co-authors, this is the most important takeaway from a new workshop report on biodiversity and climate change, the first to be jointly prepared by experts from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Intergovernmental Panel on Climate Change (IPCC). The report to which scientists from AWI, UFZ, the German Centre for Integrative Biodiversity Research (iDiv) and other institutions contributed, shows why especially phasing out fossil fuels is important for limiting global warming and for conserving nature. In addition, they demonstrate how healthy ecosystems can make long-term contributions to climate.

Dimensions of invasion success

Based on a media release of the University of Konstanz Invasive alien plants are plant species that grow in an environment outside their native habitat. If they successfully establish self-sustaining populations in these new environments – an event called “naturalization” – they can have considerable negative impacts on local ecosystems, economies, and societies. But not all alien plant species are equally effective in invading new habitats. Therefore, an international team of scientists, including several iDiv members and headed by Konstanz-based biologist Professor Mark van Kleunen, investigated different types of “invasiveness” and possible factors that determine invasion success of alien plants in Europe.

Generalists that tolerate large temperature fluctuations and feed on many different plants are most likely to benefit from human-modified habitats. In order to preserve biodiversity, urban and spatial planning should take the needs of specialised butterfly species into account, the authors recommend.

Palm Oil Plantations Change the Social Behaviour of Macaques

Based on a press release by the University of Leipzig In many parts of Southeast Asia, the rainforest is being replaced by palm oil plantations. Due to the massive clearing of their habitat, some primates move to the plantations in search of food. This often leads to conflicts with farmers, even though the monkeys hardly harm them but, on the contrary, help to keep pests such as rats at low levels. The regular stay on the plantations, however, has a massive influence on the social behaviour of the macaques. This is shown in a new study by scientists from the Max Planck Institute for Evolutionary Anthropology (MPI-EVA), Leipzig University (UL), Universiti Sains Malaysia (USM) and the German Centre for Integrative Biodiversity Research (iDiv). Living in a manmade environment could have a negative effect on the development of the offspring and thus endanger the survival of the macaque populations in the long run. The new findings, recently published in Scientific Reports, may help to develop appropriate measures for protecting the primate species, which is listed as vulnerable by the IUCN, and to promote peaceful coexistence between humans and wild animals.

Observing biodiversity change from space

Based on a media release by the University of Twente Enschede/Halle. As humans, we’re currently facing two big environmental crises: climate change and biodiversity loss. The first managed to gain a lot of public attention and funding, whereas the latter goes on more slowly in the background. One of the key problems the biodiversity crisis is facing is the few ways to monitor biodiversity. In his recent publication, an international team led by the University of Twente and with the participation of the German Centre for Integrative Biodiversity Research (iDiv) and the Martin-Luther University Halle-Wittenberg, linked existing remote sensing products to so-called essential biodiversity variables (EBVs) to measure biodiversity using satellites.

How smartphones can help detect ecological change

Leipzig/Jena/Ilmenau. Mobile apps like Flora Incognita that allow automated identification of wild plants cannot only identify plant species, but also uncover large-scale ecological patterns. These patterns are surprisingly similar to the ones derived from long-term inventory data of the German flora, even though they have been acquired over much shorter time periods and are influenced by user behaviour. This opens up new perspectives for rapid detection of biodiversity changes. These are the key results of a study led by a team of researchers from Central Germany, which has recently been published in Ecography.

Less precipitation means less plant diversity

Based on a media release by the Helmholtz Centre for Environmental Research (UFZ) Leipzig/Halle. Water is a scarce resource in many of the Earth’s ecosystems. This scarcity is likely to increase in the course of climate change. This, in turn, might lead to a considerable decline in plant diversity. Using experimental data from all over the world, scientists from the Helmholtz Centre for Environmental Research (UFZ), the German Centre for Integrative Biodiversity Research (iDiv), and the Martin Luther University of Halle-Wittenberg (MLU) have demonstrated for the first time that plant biodiversity in drylands is particularly sensitive to changes in precipitation. In an article published in Nature Communications, the team warns that this can also have consequences for the people living in the affected regions.

In future, assessments of ecosystems in terms of their contributions to people should take greater account of the importance of species diversity. This is what scientists from the German Centre for Integrative Biodiversity Research (iDiv) and the Martin Luther University Halle-Wittenberg (MLU) are calling for in the scientific journal Ecosystem Services. Animal and plant species deliver a large share of natural services for human well-being but have been in continuous decline for decades. Large-scale assessments, however, only address some of these services, such as water filtration, carbon storage and erosion control. Ecosystem services that are directly linked to species, on the other hand, hardly play a role at all. The researchers point out that this wastes many opportunities for effective nature and species conservation.

Complex river ecosystems protect freshwater fish from species loss

Report by Dr Stefano Larsen, Fondazione Edmund Mach, Italy Trento/Leipzig/Seattle. The conservation and restoration of highly branched river courses can help to curb the extinction of fish species. This is the result of an international working group led by Edmund Mach Foundation and with participation of the German Centre for Integrative Biodiversity Research (iDiv) and the Friedrich Schiller University Jena (FSU), supported by iDiv’s synthesis centre sDiv. The researchers found that temporal synchrony in the abundance of freshwater fish populations can be predicted directly from the branching complexity and connectivity of river networks. Synchronous fluctuations in the size of different populations of a species at different locations in a river significantly increase the probability of extinction. As species are lost from freshwaters faster than in any other ecosystems, knowledge of fundamental patterns in their spatial and temporal dynamics can inform conservation strategies both now and in the future. The study was recently published in Ecology Letters.

Autumn and spring are closely linked

Based on a media release by Friedrich Schiller Universität Jena The fact that plants are beginning to flower earlier and earlier as a result of climate change was reported some time ago by scientists in Jena, among others. But how do the climatic changes actually affect the other end of the growing season? To find answers to this question, biologists Dr Solveig Franziska Bucher of the Friedrich Schiller University Jena and Prof Christine Roemermann of the Friedrich Schiller University Jena and the German Centre for Integrative Biodiversity Research (iDiv) have intensively studied the so-called leaf senescence, i.e. the ageing process of plants, which can be observed, for example, through autumnal colouring or the shedding of leaves. They discovered that leaf senescence begins earlier at lower temperatures than at higher temperatures. The start of this process can differ from species to species, but the colder the environment, the faster it occurs. The study was published in the Journal of Ecology.

Does biodiversity evoke happiness?

Based on a media release by Senckenberg. Frankfurt, Leipzig, Kiel. A high biological diversity in our immediate vicinity is as important for life satisfaction as our income. These are the findings that scientists from Senckenberg, the German Centre for Integrative Biodiversity Research (iDiv), and the University of Kiel recently published in the journal Ecological Economics. For the first time, the researchers were able to show that all across Europe, the individual enjoyment of life is correlated to the number of bird species in one’s surroundings. An additional ten percent of bird species in the vicinity therefore increases the life satisfaction of Europeans at least as much as a comparable increase in income. Nature conservation thus constitutes an investment in human well-being, according to the researchers.

Their results were published in Science Advances and show that increasing plant biodiversity could help reduce pesticide inputs in agricultural systems by enhancing natural biological control.

The seductive scent of sweet fruits

The German Centre for Integrative Biodiversity Research (iDiv) adds a new research field to its portfolio. From November 2020, the biologist Dr Omer Nevo will head the new Junior Research Group ‘Evolutionary Ecology’ at iDiv and Friedrich Schiller University Jena (FSU). The 35-year-old scientist is particularly interested in chemical communication between plants and animals – in detail, how plants attract seed-dispersing animals by their fruit scent and how both sides have adapted to each other. This knowledge about the signalling effect of odours should also help to find new approaches in nature conservation. Nevo and his team will be funded for six years with about 1.3 million euros from the Emmy Noether Programme of the Deutsche Forschungsgemeinschaft (DFG).

Climate change drives plants to extinction in the Black Forest in Germany, study finds

Based on a press release by the Martin Luther University Halle-Wittenberg (MLU) Climate change is leaving its mark on the bog complexes of the German Black Forest. Due to rising temperatures and longer dry periods, two plant species have already gone extinct over the last 40 years. The populations of many others have decreased by one third. In the next couple of decades ten more species could become extinct, researchers from Martin Luther University Halle-Wittenberg (MLU) and the German Centre for Integrative Biodiversity Research (iDiv) write in Diversity and Distributions.

Biodiversity monitoring programmes need a culture of collaboration

Biodiversity loss is continuing relentlessly worldwide. In order to counteract this more effectively, monitoring programmes are needed which precisely map the circumstances of animal and plant species and the extent to which they are under threat. But too often, these are still inadequate – the range of species examined is not extensive enough, and there is too little coordination. A team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv) describes, in an article for the scientific journal One Earth how different stakeholders can combine their data and expertise to improve monitoring and thus counteract further species loss.

Land management in forest and grasslands: how much can we intensify?

Based on a media release by the University of Bern Leipzig/Bern. High land-use intensity reduces the beneficial effects of biodiversity on ecosystem services. This is the main result of a study conducted by an international team led by researchers from the Helmholtz Centre for Environmental Research (UFZ), the German Centre for Integrative Biodiversity Research (iDiv) and the University of Bern. The study published in PNAS assessed, for the first time, the effects of land management on the links between three ecosystem attributes simultaniously: biodiversity, ecosystem functions and ecosystem services. It identified thresholds of management intensity, where these relationships change dramatically, which species groups were most important in driving services, and the ecosystem services that are at risk when management is intensified.

Shifts in flowering phases of plants due to reduced insect density

Based on a media release by the Friedrich Schiller University Jena Leipzig/Jena. It still sounds unlikely today, but declines in insect numbers could well make it a frequent occurrence in the future: fields full of flowers, but not a bee in sight. A research group of the University of Jena and the German Centre for Integrative Biodiversity Research (iDiv) has discovered that insects have a decisive influence on the biodiversity and flowering phases of plants. If there is a lack of insects where the plants are growing, their flowering behaviour changes. This can result in the lifecycles of the insects and the flowering periods of the plants no longer coinciding. If the insects seek nectar at the wrong time, some plants will no longer be pollinated.

We need a safety net for biodiversity

Based on a media release by the National University of Córdoba and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) Córdoba, Leipzig, Halle. A “safety net” made up of multiple interlinked and ambitious goals is needed to tackle nature’s alarming decline. No single goal can capture the broad range of characteristics that need to be sustained, concludes a large international team with the German Centre for Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU) and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB). The study, published in the journal Science, outlines the scientific basis for redesigning the new set of biodiversity goals.

Long-term consequences of global change difficult to predict

Based on a media release by Leipzig University In a longitudinal study, an international research team led by Leipzig University (UL) and the German Centre for Integrative Biodiversity Research (iDiv) has investigated the consequences of changes in plant biodiversity for the functioning of ecosystems. The scientists found that the relationships between plant traits and ecosystem functions change from year to year. This makes predicting the long-term consequences of biodiversity change extremely difficult, they write in Nature Ecology & Evolution.

Efficient pollen identification

Based on a media release by the Helmholtz Centre for Environmental Research (UFZ)  From pollen forecasting, honey analysis and climate-related changes in plant-pollinator interactions, analysing pollen plays an important role in many areas of research. Microscopy is still the gold standard, but it is very time consuming and requires considerable expertise. In cooperation with Technische Universität (TU) Ilmenau, scientists from the Helmholtz Centre for Environmental Research (UFZ) and the German Centre for Integrative Biodiversity Research (iDiv) have now developed a method that allows them to efficiently automate the process of pollen analysis. Their study has been published in the specialist journal New Phytologist.

‘Cool’ sampling sites more likely to show false trends in biodiversity change

Leipzig/Halle. Data collected by citizen science initiatives, museums and national parks is an important basis for research on biodiversity change. However, scientists from the German Centre for Integrative Biodiversity Research (iDiv) and Martin Luther University Halle-Wittenberg (MLU) found that sampling sites are oftentimes not representative, which may lead to false conclusions about how biodiversity changes. Their research, published in Conservation Biology, calls for more objective site selection and better training for citizen scientists to prevent a site-selection bias.

Artificial intelligence can help protect orchids and other species

Leipzig/Halle. Orchids may be decorative, but many orchid species are also threatened by land conversion and illegal harvesting. However, only a fraction of those species is included in the IUCN Red List of Threatened Species, because assessments require a lot of time, resources and expertise. A new approach, an automated assessment developed under the lead of biodiversity researchers from Central Germany, now shows that almost 30% of all orchid species are possibly threatened. The findings have been published in Conservation Biology and suggest that the new approach could speed up conservation assessments of all species on Earth.

Europe’s primary forests: What to protect? What to restore?

Halle/Berlin. An expansion of the protected areas by only about 1% would sufficiently protect most remaining primary forests in Europe. This is one of the main results of a study conducted by an international team led by researchers from the German Centre for Integrative Biodiversity Research (iDiv), Martin Luther University Halle-Wittenberg (MLU) and Humboldt-Universität zu Berlin (HU). The study, published in Diversity and Distribution, is the first assessment of the conservation status of Europe’s primary forests. It identifies protection gaps and areas with restoration needs to reach conservation targets. In addition, it provides valuable information how to implement the new EU Biodiversity Strategy.

Chimpanzees show greater behavioural and cultural diversity in more variable environments

Based on a media release by the Max Planck Institute for Evolutionary Anthropology (MPI EVA) Leipzig. Chimpanzee behavioural and cultural diversity has been well documented across equatorial Africa, however, the ecological-evolutionary mechanisms are not yet understood. An international team led by the Max Planck Institute for Evolutionary Anthropology and the German Centre for Integrative Biodiversity Research (iDiv) has investigated the influence of environmental variability on the behavioural repertoires of 144 social groups. The study, published in Nature Communications, found that chimpanzees living further away from historical forest refugia, under more seasonal conditions, and found in savannah woodland rather than closed forested habitats, were more likely to exhibit a larger set of behaviours.

Bending the curve of biodiversity loss

Based on a press release by the International Institute for Applied Systems Analysis (IIASA) Laxenburg/Leipzig. Ambitious, integrated action combining conservation and restoration efforts with a transformation of the food system. This is the recipe for turning the tide of biodiversity loss by 2050 or earlier, a new study led by the International Institute for Applied Systems Analysis (IIASA) with participation of researchers from the German Centre for Integrative Biodiversity Research (iDiv) suggests. Using multiple models and scenarios, the team investigated whether and how it might be feasible to improve the status of biodiversity while at the same time complying with other sustainability targets related to land use. The study was published in Nature and forms part of the latest WWF Living Planet Report.

Awareness raising alone is not enough

Based on a media release by the Helmholtz Centre for Environmental Research (UFZ) It is a well-known problem: too rarely do nature conservation initiatives, recommendations or strategies announced by politicians lead to people really changing their everyday behaviour. A German-Israeli research team led by the Helmholtz Centre for Environmental Research (UFZ) and the German Centre for Integrative Biodiversity Research (iDiv) has investigated the reasons for this. According to the team, the measures proposed by politicians do not sufficiently exploit the range of possible behavioural interventions and too rarely specify the actual target groups, they write in the journal Conservation Biology.

Contributions of wildlife to human well-being in the scientific literature gaining in importance

Report by Joel Methorst (iDiv, Senckenberg, Goethe University Frankfurt), yDiv doctoral researcher Leipzig, Frankfurt. Non-material contributions of wildlife (WCP) to human well-being are gaining attention in the scientific literature. Whereas until the end of the 20th century only negative evaluations such as health hazards were mentioned, the focus on positive influences on physical and mental health as well as on culture aspects are now becoming increasingly popular in research. These are the main findings of a new study conducted by scientists at the German Centre for Integrative Biodiversity Research (iDiv), Senckenberg Biodiversity and Climate Research Centre (SBiK-F) and Goethe University Frankfurt. The study was published in Environmental Research Letters.

Leipzig’s floodplain suffering from chronic disease

Leipzig. Leipzig’s floodplain forest is one of the largest of its kind in Central Europe. But the floodplain is currently under huge pressure – as a result not only of drought and climate change but also of human intervention. These stressors as well as revitalization measures for the large urban forest were discussed during a visit to Leipzig’s Canopy Crane. Among the participants were Professor Beate Jessel from the German Federal Agency for Nature Conservation (BfN), Wolfram Günther from the Environmental Ministry of Saxony, Rüdiger Dittmar from the City of Leipzig and Professor Christian Wirth from the German Centre for Integrative Biodiversity Research (iDiv) and Leipzig University (UL).

Effectiveness of primate conservation measures mostly unproved

Leipzig/Halle/Cambridge. Less than one percent of scientific literature on primates evaluate the effectiveness of interventions for the conservation of primates. That is the result of a new study compiled by a team of experts in 21 countries, led by researchers from the German Centre for Integrative Biodiversity Research (iDiv), Martin Luther University Halle-Wittenberg (MLU), Max Planck Institute for Evolutionary Anthropology (MPI-EVA) and the University of Cambridge. Despite great protection efforts, this is one of the main reasons for the dramatic decline of the populations of primate species. The study published in the journal BioScience proposes several actions to improve the evidence base for the conservation of primates.

Ecologists put biodiversity experiments to the test

Based on a media release of the Senckenberg Biodiversity and Climate Research Centre  Leipzig/Frankfurt/Bern. Much of our knowledge of how biodiversity benefits ecosystems comes from experimental sites. These sites contain combinations of species that are not found in the real world, which has led some ecologists to question the findings from biodiversity experiments. But the positive effects of biodiversity for the functioning of ecosystems are more than an artefact of experimental design. This is the result of a new study led by an international team of researchers from the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), the University of Bern and the Senckenberg Biodiversity and Climate Research Centre. For their study, they removed ‘unrealistic’ communities from the analysis of data from two large-scale experiments. The results that have now been published in Nature Ecology & Evolution show that previous findings are, indeed, reliable.

Does city life make bumblebees larger?

Based on a media release of the Martin Luther University Halle-Wittenberg. Leipzig/Halle. Does urbanisation drive bumblebee evolution? A new study by Martin Luther University Halle-Wittenberg (MLU) and the German Centre for Integrative Biodiversity Research (iDiv) provides an initial indication of this. According to the study, bumblebees are larger in cities and, therefore, more productive than their rural counterparts. In Evolutionary Applications, the research team reports that differences in body size maybe caused by the increasingly fragmented habitats in cities.

Are tipping points suitable concepts for developing environmental policies?

Based on an media release of Carl von Ossietzky University Oldenburg Oldenburg/Leipzig/Halle. Many policies tackling the consequences of global environmental change rely on the concept of tipping points: If an impact, such as biodiversity loss, becomes too large, an ecosystem might flip into a different often less desirable state. However, a new study published in Nature Ecology and Evolution and led by an international team of scientists from the University of Oldenburg, the German Centre for Integrative Biodiversity Research (iDiv) and other research institutions finds little evidence for thresholds. When focussing on tipping points, scientists and policy makers may thus risk overlooking the negative impact of gradual changes on ecosystems – with potentially disastrous consequences.

Land-use change disrupts wild plant pollination

Leipzig/Halle. Human changes to the environment have been linked to widespread pollinator declines. New research published in Nature Communications shows that intensive land use will further decrease pollination and reproductive success of wild plants, especially of those plants that are highly specialised in their pollination. An international team of scientists led by researches from the German Centre for Integrative Biodiversity Research (iDiv), Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz Centre for Environmental Research (UFZ) performed a global data analysis that provided conclusive evidence of the links of human land use and pollination of plants.
