Breeding chronology, habitat utilization and nest-site selection of the long-billed curlew in northcentral Oregon

Creator:: Pampush, Geoffrey J.
Abstract:: Breeding ecology of long-billed curlews in Umatilla and Morrow Counties, Oregon, was studied during the spring and summer of 1978 and 1979. The first curlews were observed in the study areas on 16 and 19 March of 1978 and 1979, respectively. Earliest clutch completion and onset of incubation was on...

Use of the Judas goat technique to eradicate the remnant feral goat population on San Clemente Island, California

Creator:: Seward, Dawn R'Lene
Abstract:: Feral goat (Capra hircus) populations adversely impact native insular biota and physical habitats worldwide. The effectiveness of the Judas goat technique for eradicating remnant feral goats was studied on San Clemente Island (SCI), California from June 1989 through April 1991. By April 1991, 263 feral goats were killed on SCI;...

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...

Habitat use by Western Tragopans in northeastern Pakistan

Creator:: Islam, Kamal
Abstract:: Populations of Western Tragopans Tragopan melanocephalus were studied at two areas (Machiara and Salkhala) in the Neelum Valley of northeastern Pakistan. A total of 130 sightings of birds was noted during the breeding seasons in 1982 and 1983, but only 100 were re-located for vegetation analysis. More sightings of birds...

The effect of winter grazing on production and dynamics of a Lolium perenne (L.)-Trifolium repens (L.) pasture

Creator:: Jaindl, Raymond G.
Abstract:: Perennial ryegrass (Lolium perenne) - white clover (Trifolium repens) hill-land pastures were grazed at different times in the winter to study the effect of time of winter grazing on plant response and forage production. The same pastures were grazed by sheep once in early December, January, February, March, or April...

Effects of prescribed cattle grazing on reforestation in Oregon's southern Cascades

Creator:: Karl, Michael G.
Abstract:: Reforesting harvested lands in southwestern Oregon has been difficult because of low rainfall, high evaporative demand, and competitive understory vegetation. Herbicides have been a preferred method to control competing vegetation but herbicide use on federal lands was curtailed in 1984. As a result, interest in livestock grazing as a vegetation...

Habitat selection behavior in three species of anuran larvae : environmental cues, ontogeny, and adaptive significance

Creator:: O'Hara, Richard K.
Abstract:: Habitat selection behavior was investigated as a proximate mechanism influencing spatial distributions of three species of anuran larvae. Rana cascadae, Hyla regilla, and Bufo boreas overlap in distribution in lakes and ponds of the Cascade Mts. and were chosen to provide a comparative basis for analyzing habitat selection behavior. Major...

Habitat associations of bird communities in shrub-steppe and western juniper woodlands

Creator:: Reinkensmeyer, Daniel P.
Abstract:: The encroachment of western juniper into mountain big sagebrush plant communities and the subsequent development of juniper stands results in significant changes in vegetation structure and complexity. This study described and compared vegetative structure and bird community measures among four cover types representing a broad range of structural stages among...
