Synecological effects of cattle grazing riparian ecosystems

Creator:: Kauffman, John Boone
Abstract:: In 1978, a ten year project was begun to examine the synecological effects of livestock grazing riparian ecosystems. A multitude of biotic arid physical factors, many which were unique to riparian ecosystems, interacted to form a complex and diverse riparian ecosystem. A total of 256 stands of vegetation representing 60...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...

The role of ectomycorrhizal fungi in ecosystem recovery

Creator:: Amaranthus, Michael P.
Abstract:: The effect of the abundance and rapidity of ectomycorrhiza and root tip formation on conifer seedling survival and growth was investigated on disturbed forest sites in southwest Oregon and northern California. Experiments were conducted over a range of community types and environmental conditions. A range of sources of transfer soil...

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...

Simulated storm runoff characteristics between natural and altered ecosystems in the Oregon Range Validation Area

Creator:: Bolognani, Domenic Affrunti
Abstract:: During the summer of 1980 an infiltration/sedimentation study was conducted on the Oregon Range and Related Resource Validation Project Work Area in the Blue Mountains of east-central Oregon. A modified Rocky Mountain infiltrometer was used to simulate a 28 minute high intensity rainfall event to determine mean infiltration rates and...

Seasonal estimates of nitrogen fixation by Alnus rubra and Ceanothus species in western Oregon forest ecosystems

Creator:: Kim, Dong Yeob
Abstract:: Two case studies of 5 ecosystems were used to examine the nitrogen fixation rate of red alder (Alnus rubra Bong.), varnishleaf (Ceanothus velutinus var. laevigatus (Hook.) T. & G.), deerbrush (C. i ntegerrimus H. & A.), and snowbrush (C. velutinus var. velutinus Dougl. Ex Hook). The first case study assayed...

ENSO impacts on pelagic ecosystems in the Eastern Pacific, with emphasis on fishery resources

Creator:: Alvial, Adolfo L.
Abstract:: Many new research and monitoring projects, developed or initiated during ENSO 1982-83, constituted detailed descriptions of changes in specific taxa or specific processes. However, only a few projects were opportunely started or continued as regional efforts in the eastern Pacific. For those reasons, the information obtained is difficult to compare....
