Populations of pronghorn (Antilocapra americana) are subjected to multiple forms of density-dependent and density-independent regulation. Little is known about the combined effects of these variables across multiple populations throughout the landscape. The objectives of this study were to examine long-term trends in density and recruitment in pronghorn and to assess how different forms of regulation influence these trends. We used multiple density-dependent and density-independent explanatory variables in a model selection process to explain variation in pronghorn density and July fawn : doe ratios from 1955 to 1993 in 4 pronghorn management units in Nebraska. We also investigated levels …

Almost nothing is known concerning the chiropteran fauna on the Grenadine Islands, a chain of islands between St. Vincent and Grenada located near the southern end of the Lesser Antilles. Previously, only a single species—Glossophaga longirostris—had been reported from the Grenadines. Our research, conducted on 4 occasions over the period of 1980 to 2006, provided museum vouchers and genetic specimens for the addition of 4 other species to the known fauna of these islands—Noctilio leporinus, Artibeus lituratus, Artibeus schwartzi, and Molossus molossus. The Grenadines, being situated between St. Vincent and Grenada, occupy an important zoogeographic position. …
Observations Of Reproduction In Mountain Lions From Nebraska, Sam Wilson, Justin D. Hoffman, Hugh H. Genoways
Observations Of Reproduction In Mountain Lions From Nebraska, Sam Wilson, Justin D. Hoffman, Hugh H. Genoways

Occurrences of mountain lions (Puma concolor) in Nebraska have been steadily increasing; however, reproductive activity in mountain lions has not been documented in the state. We present the first evidence of mountain lion reproduction in Nebraska since mountain lions recolonized the state in the early 1990s. On 28 February 2007, a spotted kitten was hit by a vehicle in northwestern Nebraska; and based on body length and weight, we estimate its age at 3.9 months. On 20 December 2008, a female mountain lion and spotted kitten were photographed in the northwestern part of the state. On 9 May …

Understanding the geographic and environmental characteristics of islands that affect aspects of biodiversity is a major theme in ecology (Begon et al. 2006; Krebs 2001) and biogeography (Cox and Moore 2000; Drakare et al. 2006; Lomolino et al. 2006). Such understanding has become particularly relevant over the past century because human activities on continents have fragmented natural landscapes, often creating islands of isolated habitat dispersed within a sea of land uses that include agriculture, forestry, and various degrees of urban and suburban development. The increasingly fragmented or islandlike structure of mainland habitats has critical ramifications to conservation biology, as it …

Simple Predictors Of Bite Force In Bats: The Good, The Better, And The Better Still, Patricia W. Freeman, Cliff A. Lemen

Bite forces of 39 species from six families of New World bats with a variety of diets are quantified with a force meter under field conditions. Using regression approaches we search for a model that is a good morphological predictor of these bite forces. Body mass, an index that ignores differences in skull morphology, has a statistically significant relationship with bite force (R2 = 0.76) but is a relatively poor predictor compared with our best model (R2 = 0.94). The two best models of the eight we examine are one based on an estimate of strength …
New Records Of Bats From The British Virgin Islands, Gary G. Kwiecinski, Jean-Pierre Bacle, Kevel C. Lindsay, Hugh H. Genoways

As currently understood the bat fauna of the British Virgin Islands consists of five species – Noctilio leporinus, Brachyphylla cavernarum, Artibeus jamaicensis, Tadarida brasiliensis , and Molossus molossus. Our knowledge of distribution of bats in the British Virgin Islands is far more limited than that in the United States Virgin Islands. As part of ongoing research on the bats of the Virgin Islands, recent brief surveying periods in the British Virgin Islands have produced new records for some islands. Also, our researching of existing museum collections has discovered unreported new records. Our new data adds information for five species …
