  • Vertebral elemental markers in elasmobranchs : potential for reconstructing environmental history and population structure

    Creator:
    Smith, Wade D.
    Abstract:
    Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates, and rays (elasmobranchs) lack the calcified structures, known as otoliths, that are typically used for geochemical studies of...

  • The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

    Creator:
    Miller, Scott W.
    Abstract:
    I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...

  • Seasonal floodplain wetlands as fish habitat in Oregon and Washington

    Creator:
    Baker, Cynthia F.
    Abstract:
    To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...
