Hydrologic and behavioral constraints on oviposition of stream insects: implications for adult dispersal

  title={Hydrologic and behavioral constraints on oviposition of stream insects: implications for adult dispersal},
  author={Barbara L. Peckarsky and Brad W. Taylor and Christopher C. Caudill},
The supply of recruits plays an important role in plant and animal population dynamics, and may be governed by environmental and behavioral constraints on animals. Mated females of the mayfly genus Baetis alight on rocks protruding from streams, crawl under water and deposit a single egg mass under a rock. We surveyed oviposition and emergence of a bivoltine population of B. bicaudatus in multiple stream reaches in one high-altitude watershed in western Colorado over 3 years to establish… CONTINUE READING
