The effects of carnivory and herbivory on the energy balance of Arctic grizzly bears The effects of carnivory and herbivory on the energy balance of Arctic grizzly bears

Omnivores often face tradeoffs between selecting for spatially dispersed energy-dense vertebrate prey versus densely distributed herbivorous resources that have limited energetic value per unit intake. Arctic grizzly bears (Ursus arctos) are large omnivores within a resource-limited ecosystem that are known to exhibit smaller body masses and occur at lower densities than grizzly bears in...

Hosts, pathogens and hot ponds: Thermal mean and variability contribute to spatial patterns of chytrid infection Hosts, pathogens and hot ponds: Thermal mean and variability contribute to spatial patterns of chytrid infection

Temperature is a primary driver of heterogeneity in host–pathogen dynamics and understanding how patch-scale temperature affects landscape-scale patterns of pathogen infection is key to effective monitoring and management. In field studies, both temperature variability and mean temperature are often related to infection of ectothermic animals by fungal pathogens, and although these...

Amphibian diversity of the western Colorado canyonlands including potential threats from nonnative bullfrogs and disease Amphibian diversity of the western Colorado canyonlands including potential threats from nonnative bullfrogs and disease

Throughout the canyons of the Colorado and Uncompahgre Plateaus, water is a limited resource for wildlife, with patchy distribution and seasonal availability. Tributary creeks within these canyons drain into mainstem rivers, providing habitat and breeding sites for native amphibians. Yet, little is known about the diversity and distribution of amphibians that live in these harsh, dynamic

Invasive Burmese python research in the Greater Everglades

USGS leads federal research to control the highly invasive Burmese python ( Python bivittatus), which has become firmly established across the Greater Everglades Ecosystem and poses a serious threat to native wildlife. Capable of reaching over 17 feet long, this massive constrictor is believed to be a key factor in the sharp decline of mammal populations in the region. For over a decade...

Recommendations for conducting landscape assessments to inform decision making on multiple-use public lands

Landscape assessments have been proposed as a mechanism for informing conservation and natural resource management actions at broad scales. We are documenting the process used in a large effort to conduct 14 such assessments across the western United States, and evaluating how the assessments were used in subsequent land use plans. In this project, we seek to identify methods and characteristics...

The Strain and Genetic Online Tissue Repository for Chronic Wasting Disease

The Strain and Genetic Online Tissue Repository (SAGOTR) is being developed by the USGS Fort Collins Science Center to document, track, discover, and request physical samples of Chronic Wasting Disease (CWD). SAGOTR connects natural resource managers, tissue repositories, and researchers in one online platform, making it easier to locate and share samples and support research and management of CWD...
