Analysis of lion-tailed macaque habitat fragmentation using satellite imagery

Creator:: Krishnamurthy, Ramesh S. (Ramesh Saligrama), 1964-
Abstract:: Deforestation and forest fragmentation are the primary threats to the habitat of endangered lion-tailed macaques, Macaca silenus, in Karnataka, India. Landsat satellite images of northwest Karnataka, India, from 1977 and 1990 were analyzed. Two study sites, measuring 16.35 x 19.14 km (31,213 ha) and 14.34 x 21.44 km (30,561 ha),...

Creator:: Robison, Jason A.
Abstract:: The potential for Rocky Mountain mule deer (Odocoileus hemionus hemionus) to host exotic chewing lice (Damalinia (Cervicola) sp.) believed to cause deer hair loss syndrome in Columbian black-tailed deer (Odocoileus hemionus columbianus), was investigated in captive deer held in pens at E.E.

Habitat utilization by minke whales (Balaenoptera acutorostrata) in the St. Lawrence Estuary, Canada

Creator:: Zeppelin, Tonya K.
Abstract:: Characteristics of minke whale (Balaenoptera acutorostrata) habitat at the head of the Laurentian Channel in the St. Lawrence Estuary, Canada were identified by quantifying environmental and temporal habitat variables and comparing them to the presence or absence of minke whales during the summer of 1996. Identification photographs of minke whales...

The effects of forage improvement practices on Roosevelt elk in the Oregon Coast Range

Creator:: Stussy, Rosemary J.
Abstract:: Forage availability, diets, distribution, and productivity were compared for Roosevelt elk, Cervus elaphus roosevelti, using improved (i.e. seeded, fertilized, and grazed) and untreated areas of the Oregon Coast Range. Seasonal forage availability was substantially different on 1-year-old improved and untreated clearcuts, but the differences diminished by clearcut age 4 and...

Factors influencing spawning site choice by female Garibaldi, Hypsypops rubicundus (Pisces: Pomacentridae)

Creator:: Sikkel, Paul C.
Abstract:: The garibaldi, Hypsypops rubicundus, is a sexually monochromatic pomacentrid found in rocky subtidal areas of Southern and Baja California. During the spawning season, males attempt to attract females to a nest of red algae located within individually defended territories. Females were observed to enter the nests of several males before...

Population attributes and habitat selection of recolonizing mountain beaver (Aplodontia rufa)

Creator:: Hacker, Amy L.
Abstract:: I investigated the population attributes and habitat selection of mountain beaver (Aplodontia rufa) recolonizing clearcuts in the Coast Range mountains of Polk and Lincoln counties, Oregon between June 1989 and August 1990. The population characteristics of colonizing mountain beaver were evaluated in 12 stands of 3 types: 1-year-old clearcuts assumed...

Status and habitat use of California bighorn sheep on Hart Mountain, Oregon

Creator:: Kornet, Christine Anne
Abstract:: California bighorn sheep (Ovis canadensis californiana) were studied on Hart Mountain, Oregon, during the summer and fall of 1976, and the spring of 1977. The population consisted of a minimum of 196 sheep in June, 1977. The high number of lambs observed and high lamb:ewe ratios throughout both years of...

Abstract:: A herd of California bighorn sheep (Ovis canadensis californiana), re-introduced to the area of Hell Creek on the Sheldon National Wildlife Refuge in northwestern Nevada, was studied from 15 June 1978 to 20 August 1980. Major vegetation and physiographic types were delineated and described. Habitat preferences were determined from field...

Status and habitat use of Columbian white-tailed deer in Douglas County, Oregon

Creator:: Smith, Winston Paul
Abstract:: A study conducted May 1978-December 1980 determined that the present geographic range of Columbian white-tailed deer, Odocoileus virginianus leucurus, (CWTD) in Douglas County, Oregon encompassed 1199km2. The area was predominately a Quercus woodland community, typical of the Interior Valley Zone of western Oregon. The CWTD distribution was not contiguous throughout...

Potential effects of ungulate exclusion fencing on displaying Hawaiian Petrels (Pterodroma sandwichensis) at Hawai'i Volcanoes National Park

Creator:: Swift, Roberta
Abstract:: Recently the National Park Service has proposed raising fence heights to exclude mouflon sheep (Ovis musimon) from conservation areas at Hawai'i Volcanoes National Park. Concern over previous mortality of Hawaiian Petrels (Pterodronia sandwichensis) due to collision with fences prompted this study to quantify the potential effects of raising fence heights...

Ecology of feral pigs on Santa Catalina Island

Creator:: Baber, Daniel W.
Abstract:: A feral pig population on Santa Catalina Island, California, was studied for 17 months beginning in July 1980. Density was estimated to be 21 to 34 pigs/km² (95% confidence interval) using capture-recapture techniques. Dry season home ranges determined from radio-telemetry data were small and differed significantly between boars and sows....

Advantages of habitat selection and sexual segregation in mule and white-tailed deer

Creator:: Main, Martin Benjamin
Abstract:: I studied sexual segregation in mule deer (Odocoileus hemionus) and white-tailed deer (Q. virginianus) in different environments and at different population densities to test the hypothesis that sexual segregation occurs in ungulates as the result of different reproductive strategies; females select habitat and behave in manners primarily designed to promote...

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...

Temporal changes in the feeding habits of bullfrogs from three different habitat types in the Willamette Valley, Oregon

Creator:: Bouska, Cassie K.
Abstract:: Bullfrogs were introduced into Oregon in the early 1900s and have become widespread members of many wetland communities. Little is known of their ecology outside their native range, although they may play a role in the current declines observed in native herpetofauna. I analyzed the diets of 401 bullfrogs from...
