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...

Life-history organization of herring (Clupea harengus pallasi) in the northeast Pacific

Creator:: Aleaziz, Farzad
Abstract:: The distribution of herring (Clupea harengus pallasi) in the Northeast Pacific extends from southern California to northern Alaska. Studies on variation in herring life-history are limited to local characteristics and recruitment populations or relatively restricted regions of the Northeast Pacific. In this study I assessed herring life-history patterns and recruitment...

Interactions between stocked trout and larval salamanders (Ambystoma macrodactylum) in high-elevation lakes

Creator:: Tyler, Torrey J.
Abstract:: The long-toed salamander (Ambystoma macrodactylum) is the top vertebrate predator in fishless high-elevation lakes in North Cascades National Park Service Complex (NOCA), Washington. The purpose of this research was to determine the effects of physico-chemical factors and introduced trout on abundance and behavior of A. macrodactylum larvae. Although high-elevation lakes...

Distribution of nearshore macroinvertebrates in lakes of the northern Cascade Mountains, Washington, USA

Creator:: Hoffman, Robert L.
Abstract:: Although nearshore macroinvertebrates are integral members of high mountain lentic systems, knowledge of ecological factors influencing their distributions is limited. Factors affecting distributions of nearshore macroinvertebrates were investigated, including microhabitat use and vertebrate predation, in the oligotrophic lakes of North Cascades National Park Service Complex, Washington, USA, and the conformity...

Stream habitat classification and restoration in the Blue Mountians of northeast Oregon

Creator:: Ebersole, Joseph Lamar
Abstract:: The restoration of rivers and streams should be based on a strong conceptual framework. Streams are developing systems. As such, streams exhibit temporal behaviors that change with changing stream environments. Underlying the dynamic development of streams is potential capacity. Streams express this capacity as an array of habitats over time...

Effects of exploitation on life-history characteristics of spiny lobster populations (Panulirus homarus) off Oman

Creator:: Alabdulsalaam, Thabit Z.
Abstract:: The purpose of this research was to examine the effects of fishing on life history parameters of the spiny lobster, Panulirus homarus. The study areas selected had different levels of fishing pressure but relatively similar habitats. The lowest fishing effort was found in Hadbin while the highest fishing effort was...

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...

Development of the fisheries of the Eastern North Pacific : a natural-cultural systems perspective

Creator:: Deimling, Elisabeth A.
Abstract:: The eastern margin of the Eastern North Pacific Ocean was classified into physiographic regions based on a suite of physical characteristics. Information on cultural and biological characteristics of this area was meshed with this classification. The result was a classification of the Eastern North Pacific into natural-cultural systems whose boundaries...

Anthropogenic activities associated with the status of salmon stocks in Pacific Northwest watersheds

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...
