Definition of the Subject Food webs refer to the networks of feeding (“trophic”) interactions among species that co-occur within particular habitats. Research onfood webs is one of the few subdisciplines within ecology that seeks to quantify and analyze direct and indirect interactions among diver...

IVCommunity Ecology AFood Webs and Feeding Strategies Aquatic food websare supported by some combination of autochthonous (internal) and allochthonous (external) sources ofprimary production. Examples of the former are algae, cyanobacteria, mosses, and aquaticvascular plants, while the latter include org...
food web that are within a certain body-mass range, including other consumers (Fig. 3a,b)41. By this definition, similarly sized species are redundant (as species 13 and 14 inFig. 3a,b), while differently sized species are complementary (as species 11 and 12 inFig. 3a,b). Also, ...

This definition allows a convenient way to compare the topological roles of different species. In particular, given any two species a and b with motif-role profiles \(\vec c_a\) and \(\vec c_b\), we used the Pearson’s correlation coefficient to define a “measure” of similarity ...
By this definition, similarly sized species are redundant (as species 13 and 14 in Fig. 3a,b), while differently sized species are complementary (as species 11 and 12 in Fig. 3a,b). Also, larger predators occupy a higher trophic position in the food web which forms distinct trophic ...
