Effect of invasive earthworms on intraspecific plant trait variation, biotic interactions and community composition.

picture source: DFG Project Proposal Prof. Dr. Nico Eisenhauer, Leipzig

DFG Project Proposal was accepted!

The invasion of exotic earthworms often causes non-random changes in diversity above- (Craven et al. 2017) and belowground (Eisenhauer 2010, Ferlian et al. 2018), suggesting that earthworm invasion may alter how trait-mediated mechanisms impact ecosystem functioning. The EcoMeteor platform will support the group of Professor Nico Eisenhauer and perform the untargeted metabolomics analysis for profile comparison.

 

 


Sandra Boswinkel: Geographical location influences insect performance

EcoMeteor and MIE welcome Sandra Boswinkel

Sandra Boswinkel is a Bachelor Student from Radboud Unversity in Nijmwegen. In the course of her bachelor thesis she´s investigating the effects of geographical location on insect performance by comparing the performance of inland versus coastal populations of solanum dulcamara when they are exposed to the Colorado potato beetle (Leptinotarsa decemlineata). Solanum dulcamara belongs as potato to the family of Solanacea and was therefore selected as model plant  to investigate potato pests. Furthermore, previous research on coastal vs inland populations of solanum dulcamara showed that the coastal plants were less desired than inland plants what might be due to their higher glycoalkaloid content. During her research stay from the 04th to the 15th of March, Sandra analyzed the abundance of glycoalkaloids and phytohormons in the leaves of Solanum dulcamara collected at 8 different collecting points from the coast and in the inland of the Netherlands.

EcoMeteor and MIE are hosting Dr. Hisham Abd El-lateaf

Dr. Hisham Abd El-lateaf from the National Research Centre in Cairo spends a 2-weeks research stay with the EcoMetEoR platform in iDiv.

In his current project he is studying the analysis and quantification of glucosinolates in seeds and meals of moringa oleifera and moringa peregrina.The aim of this project is to maximize the utilization of the moringa meal that remains after oil extraction. By Studying the effect of using different procedures for oil extraction including (hydraulic pressing, Screw pressing and extraction by solvent) from two species of moringa seeds grown in Egypt (moringa oleifera and moringa peregrina) on the content of their meals of glucosinolates qualitatively and quantitatively with emphasis on the biological activity of pure glucosinolates against different cancer cell lines. In addition the investigation also aims to study the effect of aqueous treatment of the cakes of the previous two species of moringa seeds on the content of their meals of glucosinolates.

New guests in iDiv- EcoMetEoR hosts Dr. Aarti Gupta and Dimitri Orine

 Dr. Aarti Gupta and PhD Dimitri Orine are visting the EcoMetEoR platform to analyze the content of chlorogenic acids and different glycoalcaloids in Solanum lycopersicum under different watering conditions and myccorhiza colonization.

Dimitri Orine is a PhD student from the University of Neuchâtel in Switzerland. He is involved in a European Innovative Training Network called “Microbe-induced Resistance to Agricultural Pests”.This project is focused on basic and applied research on context-dependency of microbe-induced resistance, mechanisms, and impacts on plant performance and other biocontrol organisms. The aim is to improve our ability to predict the effectiveness of microbe-induced resistance under different biotic and abiotic conditions.As a part of the project, he carries out fundamental research to investigate the effect of eco-climatic adaptation into tolerance-induction by microbes against herbivore pests.

Dr. Aarti Gupta is a Post-doctoral Fellow at Institute of Plant Genetics at the Polish Academy of Sciences in Poznan (Poland).Her current research involves understanding the molecular mechanisms of incompatible interaction between the Hypericum perforatum and the non-host pathogen Agrobacterium tumefaciens. For the purpose, she is employing transcriptomic, biochemical and functional genomics tools. Here at iDiv, she´s attending a comprehensive hands-on training on metabolomes, glucosinolates, and phytohormones extraction and data analysis.

Successful Workshop "Introduction to Ecometabolomics for Ecologists"

From the 27th to 31st of August 15 PhD Students and 1 PostDoc participated the introductory workshop "Introduction to Ecometabolomics for Ecologists". The week was filled with lectures, hands-on sessions and many discussions aboutthe application of metabolomics in ecological research. The participants learned about the design of a metabolomic experiment, how to extract the metabolites and collect volatile compounds and how to process and interpret the MS Data.

From the 16th to the 18th of October 2017, 34 experts from Ecology,  Biochemistry and Bioinformatics joined together at the iDiv core centre to discuss the current challenges and pitfalls of applying Metabolomics in ecological studies. They discussed  experimental designs, analytical platforms, peak detection algorithms, tested data processing workflows and multivariate statistical analyses. During the workshop, the participants also explored the different bioinformatic tools which are currently available for metabolomics data processing and identification. 

As fruitful outcome of this international meeting the review "Current Challenges in Plant Ecometabolomics"  has been published by 30 participants in the International Journal for Molecular Science as part of the Special Issue Metabolomics in the Plant Sciences 2017.
