Selective Feeding Determines Patterns of Nutrient Release by Stream Invertebrates

  title={Selective Feeding Determines Patterns of Nutrient Release by Stream Invertebrates},
  author={James M Hood and Camille McNeely and Jacques C Finlay and Robert W. Sterner},
One common stoichiometric approach to predicting patterns of nutrient release (excretion + egestion) by animals in aquatic ecosystems is to base predictions on elemental mass-balance constrained by homeostatic maintenance. An easily measured resource composite (i.e., seston, epilithon, or leaf litter) often is used to represent ingested stoichiometry, but whether such a composite is a good indicator of food actually ingested is a relatively unexplored assumption. We examined the application of… CONTINUE READING
