Control and biology of feral goats on Aldabra Atoll, Republic of Seychelles

Creator:: Rainbolt, Raymond E.
Abstract:: The control of feral goats (Capra hircus) and relevant aspects of their biology were studied on Aldabra Atoll, Republic of Seychelles, from October 1993 - May 1994 and November 1994 - May 1995. A total of 832 goats were killed on Aldabra using both the Judas goat technique and traditional...

Use of the Judas goat technique to eradicate the remnant feral goat population on San Clemente Island, California

Creator:: Seward, Dawn R'Lene
Abstract:: Feral goat (Capra hircus) populations adversely impact native insular biota and physical habitats worldwide. The effectiveness of the Judas goat technique for eradicating remnant feral goats was studied on San Clemente Island (SCI), California from June 1989 through April 1991. By April 1991, 263 feral goats were killed on SCI;...

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),...

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...

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...
