Cover Story: Consumer-driven nutrient recycling is an important component of the dynamics of a variety of terrestrial and aquatic ecosystems. However, the drivers of variation in nutrient excretion stoichiometry among closely related populations and species remain unclear. To address this question, we studied an assemblage of phosphorus-rich armored catfishes in the family Loricariidae in Panamanian streams. Although many loricariids feed on algae and detritus, there is considerable trophic diversity within the family. Among Panamanian species, we found a positive relationship between and excretion N:P ratio and trophic position, but no relationship with body N:P ratio. Our results suggest that body stoichiometry may only be a significant predictor of excretion rates and ratios when organisms have similar diets. View this paper.
