Laboratory stream communities in simulated old growth second
order streams were sampled June 1984 and June 1985 to advance an
understanding of their organization and development, and their
response to an environmental perturbance, the toxicant dieldrin. An
interpenetrating hierarchical view of habitats and community
subsystems was taken to conceptualize community...
Factors affecting physical, chemical, and biological characteristics of lakes
were investigated through the development of a lake-classification system for 162
lakes in North Cascades National Park Service Complex. A conceptual view of lake
development and its relationship to the expression of lake and watershed
characteristics was derived. Water quality and...
This is a Biological Assessment (BA) addressing the potential effects on aquatic species currently listed or proposed for listing under the Federal Endangered Species Act (ESA) from the construction of the National Oceanic and Atmospheric Administration’s (NOAA) Marine Operations Center – Pacific (MOC-P) in Newport, Oregon. The MOC-P is proposed...
Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...
Sage grouse (Centrocercus urophasianus) populations in Oregon
declined during the past 30 years as a result of impaired productivity.
The western subspecies (C. u. phaios) was listed as a candidate for
threatened and endangered status by the Department of the Interior in
1985 because of declines in Oregon and Washington...
The potential impact of projected climate warming on the terrestrial hydrologic cycle is
uncertain. This problem has evaded experimentalists due to the overwhelming challenge of measuring the
entire water budget and introducing experimental warming treatments in open environmental systems. We
present new data from a mesocosm experiment that examined the...
