Resource partitioning of four sympatric mynas and starlings (Sturnidae) in Thailand

Creator:: Tunhikorn, Schwann
Abstract:: Patterns of resource partitioning among 4 sympatric sturnids: [black-collared starling (Sturnus nigricollis), pied starling (S. contra), common myna (Acridotheres tristis) and crested myna (A. javanicus) were determined based on their food habits, foraging and nesting microhabitat selection, morphology and behavior. The study was conducted from March 1986 to June 1988...

Efficacy of sodium fluoroacetate in reducing ground squirrel damage to alfalfa

Creator:: Kalinowski, Stephan A.
Abstract:: Damage by Belding's ground squirrel (Spermophilus beldingi) to alfalfa (Medicago sativa) and the efficacies of various poisoning regimes to reduce damage were evaluated during March-July, 1976 and 1977. Regimes examined were designed to measure the effect of 3 variables on damage to alfalfa caused by squirrels including; timing of application,...

Food selection, home range, and movements of coyotes on and off a sanctuary in Klamath Basin

Creator:: Shoemaker, Suzanne
Abstract:: Radio-telemetry and scat analysis were used to investigate daily and seasonal movement patterns and food selection of a protected coyote population on Tulelake National Wildlife Refuge (TLNWR) and adjacent Lava Beds National Monument (LABE) in northeastern California. Study emphasis was on evaluation of movements on and off the sanctuary, and...

Ecology and behavior of bison in the Henry Mountains, Utah

Creator:: Van Vuren, Dirk
Abstract:: Aspects of bison ecology and behavior were studied in the Henry Mountains, Utah during summer 1977 and summer 1978. Foraging distributions of bison and of cattle were compared to elevation, slope, horizontal distance from water, vertical distance from water, aspect, and availability of preferred forage. The effect of bison-cattle interactions...

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...
