  • Cumulative effects of land use on salmon habitat in southwest Oregon coastal streams

    Creator:
    Frissell, Christopher Andrew, 1960-
    Abstract:
    As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which...

  • Heterogeneous thermal habitat for northeast Oregon stream fishes

    Creator:
    Ebersole, Joseph L.
    Abstract:
    Discrete coldwater patches within warm streams provide potential thermal refuge for coldwater fishes during periods of heat stress. This analysis focused on heterogeneity in stream water temperatures as influenced by local influx of cooler subsurface waters. Using field thermal probes and recording thermistors, we identified and characterized coldwater patches potentially...
