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 evaluation of the Earth Resources Technology Satellite (ERTS-1) multispectral scanner as a tool for the determination of lacustrine trophic state

Creator:: Boland, Dale H. P.
Abstract:: This study evaluates the Earth Resources Technology Satellite- One (ERTS-1) multispectral scanner (MSS) as a means of predicting lacustrine trophic state and the magnitude of selected trophic state indicators. Numerical classificatory methods are employed to ascertain the trophic character of 100 lakes in Minnesota, Wisconsin, Michigan, and New York using...

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...

Aquatic Plant Community Changes in Freshwater Ponds Recently Invaded by Elodea canadensis on the Western Copper River Delta, Alaska

Creator:: Elizabeth, Camarata A.
Abstract:: Establishment of a non-native plant species in new habitats beyond their native range is associated with inherent changes in ecosystem properties. These changes may be dramatic or subdued, and consequences may be positive or negative depending on characteristics and response of the resident ecosystem. Non-native aquatic plant species in the...

Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

Creator:: Kaylor, Matthew J.
Abstract:: Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

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...

Detection, classification and ecology of acoustic scattering layers

Creator:: Cade, David Edmund
Abstract:: Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...

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...
