  • 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...

  • 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...

  • Riparian vegetation and abundance of woody debris in streams of southwestern Oregon

    Creator:
    Ursitti, Victoria L.
    Abstract:
    Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...
