Lotic macroinvertebrate distribution patterns in northeastern Oregon

Creator:

Gerth, William J.

Abstract:

This study was an investigation of lotic macroinvertebrate distribution in northeastern Oregon at two different spatial and biological scales. Examination of assemblages at a limited spatial scale revealed relationships with natural and disturbance gradients and led to questions about distribution of a population at broader spatial scales. In a 16...

An economic analysis of alternative water allocations and habitat investments for anadromous fish production, John Day Basin, Oregon

Creator:

Cerda, Arcadio Alberto

Abstract:

This thesis focuses on the economic efficiency of alternative habitat, streamfiow, and land use allocations within a major drainage of the Pacific Northwest. Specifically, productivity of present habitat and streamfiow conditions is evaluated with respect to anadromous fish species (chinook salmon and steelhead trout) in the John Day River Basin,...
