The study of food webs is a very important topic in order to understand the dynamics and stability of communities. We studied the food webs structure and energy balance of some tide pools from a rocky shore of Mar del Plata (Argentina). Food webs were drawn, and connectivity, proportion of different trophic species, and the link-richness regression slope were determined. Photosynthesis and respiration rates of several species were also measured. All the topological measures were calculated with and without sediments/detritus as potential energy sources. The proportion of basal species and the connectivity were greater when detritus were included; proportion of intermediate species lowed significantly with detritus inclusion. There were no differences between seasons, but sampling sites did show differences. Proportion of top species and connectivity did not show differences in any cas.. View More»
