Microhabitat preferences of benthic fauna in a woodland stream

  title={Microhabitat preferences of benthic fauna in a woodland stream},
  author={Donald J. Orth and O. Eugene Maughan},
Estimates of numbers, biomass, and diversity of benthic macroinvertebrates were made quarterly over a two-year period to investigate microhabitat preferences. Although biomass of most taxa was significantly different among sampling times, physical factors also appeared to be important in determining abundance of many taxa. Optimum depth, velocity, substrate type, and turbulence were determined for major taxa. Optimum conditions for diversity appeared to be 34 cm depth, 60 cm s−1 velocity, and… CONTINUE READING
