Predators In Natural Fragments: Foraging Ecology Of Wolves In British Columbia’S Central And North Coast Archipelago, C. T. Darimont, M. H. H. Price, N. N. Winchester, J. Gordon-Walker, P. C. Paquet

Biogeography and Ecological Opportunity Collection

Aim Predator–prey dynamics in fragmented areas may be influenced by spatial features of the landscape. Although little is known about these processes, an increasingly fragmented planet underscores the urgency to predict its consequences. Accordingly, our aim was to examine foraging behaviour of an apex mammalian predator, the wolf (Canis lupus), in an archipelago environment.

Location Mainland and adjacent archipelago of British Columbia, Canada; a largely pristine and naturally fragmented landscape with islands of variable size and isolation.

Methods We sampled 30 mainland watersheds and 29 islands for wolf faeces in summers 2000 and 2001 and identified prey remains. We examined …

The Florida Bonneted Bat, Eumops Floridanus (Chiroptera: Molossidae): Distribution, Morphometrics, Systematics, And Ecology, Robert M. Timm, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

A review and reappraisal of bats of the genus Eumops (Chiroptera: Molossidae) reveals that considerable geographic variation is present in the bonneted bat, E. glaucinus; it is a complex consisting of >1 species. Bonneted bats in Florida are significantly larger than those in all other populations, and have proportionally shorter and deeper basisphenoid pits, the glenoid fossa is broadly triangular with rounded apices, and bacular shape differs from that in other populations. Additionally, bonneted bats in Florida have a broader palate than bats from populations in South America. Given these differences, the correct name for both Pleistocene and Recent …

The Impact Of Species Concept On Biodiversity Studies, Keith A. Crandall, Paul-Michael Agapow, Olaf R. P. Bininda-Emonds, John L. Gittleman, Georgina M. Mace, Jonathon C. Marshall, Andy Purvis

Species are defined using a variety of different operational techniques. While discussion of the various methodologies has previously been restricted mostly to taxonomists, the demarcation of species is also crucial for conservation biology. Unfortunately, different methods of diagnosing species can arrive at different entities. Most prominently, it is widely thought that use of a phylogenetic species concept may lead to recognition of a far greater number of much less inclusive units. As a result, studies of the same group of organisms can produce not only different species identities but also different species range and number of individuals. To assess the …

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Faculty Scholarship

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife conflict …
