Land use distributions and changes in the Willamette Valley in relation to soil characteristics

Creator:: Wiens, John Herbert
Abstract:: A study was undertaken in the Willamette Valley, Oregon, to document 1971 land use patterns as well as land use change in a smaller study area in the 16 years prior, and to relate these to soil characteristics. Quantification of these inter-relationships was aided by use of computer tabulation and...

Structural and functional analysis of the 57 kDa protein produced by the fish pathogen, Renibacterium salmoninarum

Creator:: Wiens, Gregory D.
Abstract:: Little is known about the virulence factors of Renibacterium salmoninarum, the causative agent of salmonid bacterial kidney disease. The predominant protein produced by R. salmoninarum in broth culture or during infection is a 57/58 kDa protein (p57) which is associated with strain virulence. In this study monoclonal antibodies (MAbs) to...

Competitive interactions and resource partitioning between northern spotted owls and barred owls in western Oregon

Creator:: Wiens, J. David
Abstract:: The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

The water economy of the Sage Sparrow, Amphispiza belli nevadensis (Ridgway)

Creator:: Moldenhauer, Ralph Roy
Abstract:: This study investigated several physiological aspects of the water economy of the Sage Sparrow, Amphispiza belli nevadensis,as they relate to the ability of this species to inhabit xeric desert environments. When maintained in captivity on a dry diet without drinking water, Sage Sparrows gradually lost weight and died. During the...

Resource allocation in four syntopic species of marine diving birds

Creator:: Scott, James Michael, 1941-
Abstract:: During 1969-1971 I studied patterns of resource allocation and behavioral interaction among Brandt's Cormorants, Pelagic Cormorants, Common Murres and Pigeon Guillemots in the area of a breeding colony on Yaquina Head on the central Oregon coast. Extensive studies of the breeding colony were combined with detailed observations of the distribution,...

Polygyny in the bobolink : habitat quality and the adaptive complex

Creator:: Martin, Stephen George, 1941-
Abstract:: The adaptiveness of polygyny in passerines poses a particularly intriguing problem. The altricial young of this group require extended parental care, but young of polygynous pairings generally lack the undivided attention of the male which young of monogamous pairings receive. Polygynous offspring may thus be undernourished and experience greater mortality....

Behavioral patterns and their temporal organization in breeding American Avocets

Creator:: Gibson, Flash
Abstract:: The organization of behavioral activities in time is important to a bird's survival and reproduction. To be successful, either proximately or ultimately, a bird must apportion its behavior in time so that it may obtain sufficient energy for maintenance activities and for such activities as migration and reproduction. The organization...
