Consumer - interaction webs and the effect of aboveground vertebrates and invertebrates on ecosystem processes

Description: Das Projekt "Consumer - interaction webs and the effect of aboveground vertebrates and invertebrates on ecosystem processes" wird vom Umweltbundesamt gefördert und von Universität Jena, Institut für Ökologie durchgeführt. The effects of invertebrate herbivory on ecosystem processes will be tested by excluding above-ground invertebrates from 5 m x 5 m subplots of all experimental plots using biocides. Net primary productivity and other ecosystem processes will be quantified in both treated and unmanipulated parts of the plot to study the relationships between plant diversity, invertebrate herbivory and ecosystem functioning. A second objective of this project is to test the interactions between plant diversity, plant productivity and the structure of the invertebrate community. Above-ground invertebrates will be sampled repeatedly from all grassland plots and allocated to a certain trophic role, i.e. herbivore, predator, parasitoid, or detritivore. Statistical modeling will reveal the influence of plant diversity manipulations on invertebrate density and invertebrate diversity at different trophic
