The food web definition in biology is a diagram that shows the transfer of energy through multiple different organisms in an area. Food webs are made of multiple food chains, which show the transfer of energy between one organism in each trophic level. To describe a food web we must understa...

Food-web theory can be a powerful guide to the management of complex ecosystems. However, we show that indices of species importance common in food-web and network theory can be a poor guide to ecosystem management, resulting in significantly more extinc

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 ...
A consumer feeds on all species present in the local 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 in Fig. 3a,b), while differently sized species are ...
