A geographical framework for assessing longitudinal patterns in stream habitat and fish distribution

Creator:: Torgersen, Christian E.
Abstract:: New approaches are needed to quantify and understand spatial patterns of stream fishes and their environment. Concepts in riverine ecology emphasize the importance of thermal zones and gradual longitudinal changes in physical habitat and biota, but little is known about spatial variability within the river continuum. I present a conceptual...

A multi-trophic level examination of recreational impacts on a national wild and scenic river

Creator:: Wright, Kristopher Keith
Abstract:: Initially, components of an aquatic food web were examined to study impacts of recreational use on the aquatic ecology of Quartzville Creek, Oregon in 1995 and 1996. Measurements of the food web components consisted of observations of harlequin ducks (Histrionicus histrionicus), visual counts of the larval caddisfly Dicosmoecus gilvipes, benthic...

An investigation of the distribution of Nephtys caecoides in Yaquina Bay

Creator:: Morrison, George Edwin
Abstract:: A study was undertaken in Yaquina Bay, Oregon during the summer of 1964 to determine the distribution and the factors affecting the distribution of the polychaete worm, Nephtys caecoides, Hartman, 1938, in the estuary. This organism has a continuous distribution from offshore to a point approximately eight kilometers into the...

Classification and management of earthen aquaculture ponds, with emphasis on the role of the soil

Creator:: Bowman, James R.
Abstract:: Soil, water, and climatic classification systems are reviewed as background for the construction of a classification system for earthen aquaculture ponds. The physical and chemical properties of important soil types are also reviewed because of the critical role that the soil plays in earthen pond systems. A pond classification system...

Coniferous Forest Biome : summary of research and synthesis activities July 1975-August 1976

Creator:: Edmonds, Robert L., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Research activities in the post-IBP phase of the Biome program prior to July 1975 were reported in Internal Report 162. Summaries of research and synthesis activities from July 1975 to August 1976 are presented here. The reports are arranged in the following order: Analysis of individual terrestrial ecosystems, which has...

Distribution of Euphausiacea and Copepoda off Oregon in relation to oceanographic conditions

Creator:: Hebard, James Frank
Abstract:: Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...

Ecological relationships among western Ephemerellidae : growth, life cycles, food habits, and habitat relationships

Creator:: Hawkins, Charles Patrick
Abstract:: The purpose of this study was to describe the life cycles, feeding ecology, and habitat use of western species in the mayfly family Ephemerellidae. Data were used to compare the ecological relationships and strategies among species and to examine patterns of adaptive radiation within the family. Data were further used...

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...
