  • From continua to patches : longitudinal patterns in the Middle Fork of the John Day River, Oregon

    Creator:
    Wright, Kristopher Keith
    Abstract:
    The Middle Fork John Day River is composed of low gradient, alluvial valley segments separated by constrained, canyon-like reaches, and has a history of multiple land-uses. These factors can alter the physical and biological structure of streams, and disrupt the longitudinal river continuum. I examined habitat, fish, macroinvertebrates, and primary...

  • Lotic macroinvertebrate distribution patterns in northeastern Oregon

    Creator:
    Gerth, William J.
    Abstract:
    This study was an investigation of lotic macroinvertebrate distribution in northeastern Oregon at two different spatial and biological scales. Examination of assemblages at a limited spatial scale revealed relationships with natural and disturbance gradients and led to questions about distribution of a population at broader spatial scales. In a 16...
