Body size, trophic position, and the coupling of different energy pathways across a saltmarsh landscape

Abstract Body size is considered an important structuring mechanism of food webs because consumers are usually larger and more mobile than their prey and may couple energy among habitats. We explored the links among trophic position (TP), body size, and the coupling of different energy channels (phy...
