A distinguishing feature of many ecological networks in the microbial realm is the diversity of substrates that could potentially serve as energy sources for microbial consumers. The microorganisms are themselves the agents of compound diversification via metabolite excretion or overflow metabolism. It has been suggested that the emerging richness ...
ARENA: Assessment of pest biocontrol in arable crops by naturally ocuring pest enemies: sampling network and tools to integrate this ecosystem service into integrated crop management Promoting pest biological control within agrosystems is a way to reduce the use of pesticides. The lack of quantification tools of this ecosystem service is a major ob...
Comparing the architecture of interaction networks in space or in time is crucial to understand community assembly, trajectory, functioning and persistence. Graph embeddings, that map networks into a vector space where close networks have similar architectures, might represent ideal tools for that purposes.Here, we evaluated the capacity of seven g...

Fish are both consumers and prey, and as such part of a dynamic trophic network. Measuring how they are trophically linked, both directly and indirectly, to other species is vital to comprehend the mechanisms driving alterations in fish communities in space and time. Moreover, this knowledge also helps to understand how fish communities respond to ...

It is predicted that warmer conditions should lead to a loss of trophic levels, as larger bodied consumers, which occupy higher trophic levels, experience higher metabolic costs at high temperature. Yet, it is unclear whether this prediction is consistent with the effect of warming on the trophic structure of natural systems. Furthermore, effects o...
Parasites have been excluded from most food web constructions, partly because of their assumed negligible contribution to the flow and stock of energy in ecosystems. These assumptions have been disputed. Parasites also present practical and conceptual problems in knowing how best to represent them in trophic networks that use simple graphical descr...
Uncovering the predation habits of small arthropods such as mites can be a major challenge, as direct observations are not always feasible in natura. Therefore, PCR-based analyses of gut content, or body content when gut dissection is not applicable, are being increasingly used to detect remains of prey items. Here, we present an integrative approa...
Climate change is likely to impact all trophic levels, although the response of communities and ecosystems to it has only recently received considerable attention. Further, it is expected to affect the magnitude of species interactions themselves. In this chapter, we summarize why and how climate change could affect predator–prey interactions, then...

Symbiosis is a common phenomenon in nature that substantially affects organismal ecology and evolution. Fundamental questions regarding how mutualistic associations arise and evolve in nature remain, however, poorly studied. The aphid-Serratia symbiotica bacterium interaction represents a valuable model to study mechanisms shaping these symbiotic i...
