Ana Carolina Antunes
I am a woman in science, with great interest in tropical forest ecology, food web ecology, and the influence of anthropogenic activities on ecosystem processes.
I joined yDiv looking for professional and personal development, in an interdisciplinary and creative environment. It is also an interesting opportunity to connect to the research of other groups.
During my Master I worked with vertebrate-plant interactions and dynamics of floodplain forests in the Amazon Forest. I have also worked on the Biological Dynamics of Forest Fragments Project (PDBFF), trying to understand how forest fragmentation affects the phenology of terra firme forest trees.
Now in my PhD project I’m interested in better understanding how changes in biodiversity are affecting ecosystem function and services. More specifically, I’m working in the FutureWeb project, investigating how continuous climate and land-use change are expected to impact species interactions and links between trophic levels in the food web
My Research Project
In a scenario of continuous climate and land-use change, the expected high loss of biodiversity affects the functioning of ecosystems and the ability of natural ecosystems to deliver ecosystem services. Yet, there is no mechanistic underpinning of this expected change to generate quantitative predictions. In this study, we will use metabolic theory to predict the total energy fluxes between consumers and resources in a vertebrate food web, and directly relate these fluxes to specific ecosystem functions and services provided by vertebrates (pest control, regulation of open areas, regulation of herbivores, cultural services). Pixel-based distributions of the vertebrate food web across Europe will provide quantitative estimates of ecosystem services at a resolution of 1km. Both climate and land use change modify the population abundances and probability of presence, which will be accounted for in new allometric scaling relationships. Changes in food-web structure caused by species extinctions modify all fluxes in the food web via direct and indirect effects. Together, these relationships facilitate the modelling of food-web energy fluxes and the resulting ecosystem functions under future conditions of higher ambient temperatures, different land-use types and lower species richness.
