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...

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...

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...
