Divergence in trophic ecology characterizes colonization of extreme habitats

  title={Divergence in trophic ecology characterizes colonization of extreme habitats},
  author={Michael Tobler},
Extreme habitats are characterized by the presence of physio-chemical stressors, but also differ in aspects of the biotic environment, such as resource availability or the presence of competitors. The present study quantifies variation in trophic ecology of a small livebearing fish (Poecilia mexicana, Poeciliidae) across four different habitats that included nonsulphidic and sulphidic surface waters, as well as a nonsulphidic and a sulphidic cave. Resource use in different habitat types was… CONTINUE READING
