Predator Identity and Ecological Impacts : Functional Redundancy or Functional Diversity ?

  title={Predator Identity and Ecological Impacts : Functional Redundancy or Functional Diversity ?},
  author={David R. Chalcraft and William J Resetarits}
Different species occupy similar trophic positions in natural communities. However, ecologists have often overlooked the consequences of this variation for local communities by assuming that species occupying similar trophic positions are functionally similar. There have been few experimental tests of this important assumption. We tested the assumption of functional similarity by comparing the effect of six different predators (three fish and three salamander species) on an ensemble of larval… CONTINUE READING
