Experimental taxonomy, 1930-1950 : the impact of cytology, ecology, and genetics on ideas of biological classification

Creator:: Hagen, Joel Bartholemew
Abstract:: During the years between 1930 and 1950 a number of attempts were made to introduce techniques and ideas from cytology, ecology, and genetics into the field of taxonomy. Advocates of this "experimental taxonomy" believed that cytological, ecological, and genetic techniques would provide a rigorous, objective methodology to replace the traditional...

The Oregon oceanbook : an introduction to the Pacific Ocean off Oregon including its physical setting and living marine resources

Creator:: Parmenter, Tish, Bailey, Robert, Oregon. Department of Land Conservation and Development, and Oregon State University. Sea Grant College Program
Abstract:: The Oceanbook focuses on the ocean environment from the coastline to roughly 200 miles offshore, the limit of U.S. jurisdic-tion, and from Cape Mendocino, California, to Vancouver Island, British Columbia. We excluded the intertidal area of interest to low-tide beachcombers from the Oceanbook because this area is well covered in...

A hierarchical stream habitat classification system: development and demonstration

Creator:: Frissell, Christopher A.
Abstract:: Classification of Streams and stream habitats is useful for research involving establishment of monitoring stations, determining local impacts of land use practices, generalization from site-specific data, and assessment of basin-wide, cumulative impacts of human activities on streams and their biota. This thesis presents a framework for a hierarchical classification system,...

Effects of light, nutrients, and grazing on periphyton communities in streams

Creator:: Gregory, Stanley Vincent
Abstract:: Relative effects of light, nutrients, and grazing on primary production were investigated in streams in the Cascade Mountains of Oregon and in laboratory streams. Relative magnitudes of primary production and associated processes were examined for one year in a stream that flowed through a clearcut and an old-growth forest in...

Forests, fresh perspectives from ecosystem analysis : proceedings of the 40th annual Biology Colloquium

Creator:: Waring, Richard H.
Abstract:: Over the last decade a new perspective on how forest ecosystems operate has emerged. Ecosystems appear much more flexible than we once thought. Even the most persistent is still evolving in composition. Yet for all their diversity, very similar processes are seen as operating in all forests, providing a point...

Diverse consumer guilds in intertidal communities of Oregon and the Republic of Panama and their effects on prey assemblages

Creator:: Gaines, Steven D.
Abstract:: Low intertidal communities of Oregon and Panama have many predator and herbivore species. This diversity of consumers is important to the organization of both communities because of qualitative differences among the consumer species in their ability to circumvent specific prey defenses. In Oregon, the red alga Iridaea cordata is protected...
