Trophic information—who eats whom—and species' body sizes are two of the most basic descriptions necessary to understand community structure as well as ecological and evolutionary dynamics. Consumer–resource body size ratios between predators and their prey, and parasitoids and their hosts, have recently gained increasing attention due to their important implications for species'...

Comparing species interaction networks along environmental gradients: Networks along environmental gradients

Pellissier, Loïc ; Albouy, Camille ; Bascompte, Jordi ; Farwig, Nina ; Graham, Catherine ; Loreau, Michel ; Maglianesi, Maria Alejandra ; Melián, Carlos J. ; Pitteloud, Camille ; Roslin, Tomas ; Rohr, Rudolf ; Saavedra, Serguei ; Thuiller, Wilfried ; Woodward, Guy ; Zimmermann, Niklaus E. ; Gravel, Dominique

Knowledge of species composition and their interactions, in the form of interaction networks, is required to understand processes shaping their distribution over time and space. As such, comparing ecological networks along environmental gradients represents a promising new research avenue to understand the organization of life. Variation in the position and intensity of links within networks...

Consumer-resource body-size relationships in natural food webs

It has been suggested that differences in body size between consumer and resource species may have important implications for interaction strengths, population dynamics, and eventually food web structure, function, and evolution. Still, the general distribution of consumer–resource body-size ratios in real ecosystems, and whether they vary systematically among habitats or broad taxonomic...
