Project

Trophic interactions as drivers of secondary succession in tropical rainforests an experimental test in New Guinea (GA17-23862S)

This is the first experimental test for the impact of trophic interactions among plants, fungal pathogens, insect herbivores and insect and vertebrate predators on the direction of secondary succession leading to the regeneration. W...

Symbiotic microbiota of insect herbivores key to understanding of host specificity? (GA18-08803S)

What is the role of symbiotic microbiota in shaping host specificity of insect herbivores? To answer this important question, we propose to obtain novel, complex data on plant-herbivore-endosymbiont trophic interactions using rigoro...

Interaction between algae and grazers sensing the menace and responding to it (GA17-18917S)

The traditional view is that planktonic systems are affected by bottom-up processes that control resource acquisition and competition and by top-down processes linked to trophic interactions. Recently, infochemicals have been recogn...
