Planktivorous Auklets (Aethia pusilla and A. cristatella) nesting on St. Lawrence Island, Alaska as indicators of marine conditions in the northern Bering Sea

Creator:: Gall, Adrian
Abstract:: Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...

Impacts of agricultural drainwater and contaminants on wetlands at Kesterson Reservoir, California

Creator:: Schuler, Carol Ann, 1946-
Abstract:: Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and other minerals from farmland in the San Joaquin Valley of California. Aquatic plants and invertebrates were sampled at Kesterson in May, August, and December of 1984. The reservoir supported a different biota and lower species diversity than...

Over-wintering diet, growth, and prey available to juvenile coho salmon (Oncorhynchus kisutch) in the West Fork Smith River, Oregon

Creator:: Olegario, Anthony
Abstract:: Over-winter growth of juvenile salmonids may be linked to ocean survival and thus species persistence. Diet, growth, and prey available to juvenile coho, Oncorhynchus kisutch, were examined from December 2004 to April 2005 in four tributaries of the West Fork Smith River (WFSR), Oregon. Juvenile coho growth rate and condition...

Nest-site selection in cooperatively breeding Pohnpei Micronesian Kingfishers (Halcyon cinnamomina reichenbachii) : does nest-site abundance limit reproductive opportunities?

Creator:: Kesler, Dylan C.
Abstract:: Despite their inherent importance and utility as ecological examples, island species are among the most endangered and least studied groups. Guam Micronesian Kingfishers (Halcyon cinnamomina cinnamomina) exemplify the plight of insular biota as a critically endangered and understudied island bird that went extinct in the wild before they could be...

Conservation and spatial use analyses for the recovery of bighorn sheep in the Peninsular Ranges

Creator:: Ostermann, Stacey D.
Abstract:: The status of wild sheep in North America typifies the plight of many wildlife species in modern times: wild sheep have declined to 10-40% of their numbers during pristine times and on a global scale approximately 31% of Caprine are considered threatened or critical. As human populations and the number...

Population ecology of the Columbian white-tailed deer

Creator:: Gavin, Thomas Alan
Abstract:: A population of Columbian white-tailed deer (CWTD) was studied on a refuge (790 ha) in southwestern Washington during 1972-77. Quality of habitat was considered good for these deer and total population size remained between 164-230 as determined by mark-recapture methods during November. Population size declined significantly between the winters of...

Food and habitat partitioning in two groups of coexisting Accipiter

Creator:: Reynolds, Richard T.
Abstract:: Sharp-shinned Hawks (Accipiter striatus), and Cooper's Hawks (A. coo erii) in the conifer forests in northwestern Oregon and A. striatus, A. cooperii, and Goshawks (A. gentilis) in the conifer forests of eastern Oregon were syntopic during the nesting season. In this study density of nests, nest success, and utilization of...

Response of avian communities to herbicide-induced vegetation changes, western Oregon

Creator:: Morrison, Michael L.
Abstract:: The relationships between avian community structure and herbicide modification of vegetation were analyzed on early-growth clearcuts in western Oregon that had received phenoxy herbicide treatment 1 or 4 years previously. Only minor effects of herbicide treatment were evident 1-year after spraying, except for red adler (Alnus rubra), which still exhibited...

Population characteristics and habitat utilization of bighorn sheep, Steens Mountain, Oregon

Creator:: Van Dyke, Walter A.
Abstract:: A herd of re-introduced California bighorn sheep (Ovis canadensis californiana) was studied from 15 June 1976 to 31 August 1977. Thirteen major and seven minor habitats were delineated and described. Habitat use by bighorns was observed throughout the study and a habitat preference value (H.P.V.) was calculated based on use...
