Effects of climate change on wildlife in the Northern Rockies [Chapter 8]

Publications Posted on: September 22, 2017
Few data exist on the direct effects of climatic variability and change on animal species. Therefore, projected climate change effects must be inferred from what is known about habitat characteristics and the autecology of each species.

Effects of prescribed fire on wildlife and wildlife habitat in selected ecosystems of North America

Science Spotlights Posted on: March 28, 2017
Some objectives for prescribed fire include reducing fuel loads and fuel continuity, returning fire to an ecosystem, enhancing wildlife habitats, improving forage, preparing seedbeds, improving watershed conditions, enhancing nutrient cycling, controlling exotic weeds, and enhancing resilience from climate change. Regardless of the particular objective, fire affects ecosystem structure, composition, and function in many ways.

Ecosystems and watersheds

Pages Posted on: February 06, 2017
Ecosystems are spatially explicit, relatively homogeneous units of the Earth that include all interacting organisms and elements of the abiotic environment within their boundaries. They should be described in terms of their composition, structure, function, and connectivity. These publications and tools include valuable information for terrestrial ecosystems, aquatic ecosystems, and watersheds.

Wildlife, fish, and biodiversity [Chapter 11]

Publications Posted on: December 13, 2016
The 2010 Resources Planning Act (RPA) Assessment (2010 RPA) reviewed recent trends in wildlife, fish, and biodiversity, showing varied responses, depending on the resource, suggesting varied conditions that depend on region, species group, or habitat type.

Using step and path selection functions for estimating resistance to movement: Pumas as a case study

Publications Posted on: September 16, 2016
GPS telemetry collars and their ability to acquire accurate and consistently frequent locations have increased the use of step selection functions (SSFs) and path selection functions (PathSFs) for studying animal movement and estimating resistance. However, previously published SSFs and PathSFs often do not accommodate multiple scales or multiscale modeling.

Trans-kalahari predator conservation project

Science Spotlights Posted on: August 17, 2016
Populations of large carnivores are declining globally, and in Africa the ranges of lions, leopards, wild dogs and spotted hyenas have contracted dramatically in the past few decades. The goal of this project is to assess current population distribution and connectivity for these species across a vast trans-boundary region of Southern Africa, comprising the Kavango-Zambeizi Trans-Frontier Conservation Area (KAZA), which consists of most of Botswana as well as portions of Zambia, Angola, Zimbabwe, Angola and South Africa.

Quantifying the combined effects of climate, fire, and treatments on the connectivity and fragmentation of wildlife populations across the Great Basin

Projects Posted on: August 17, 2016
Over one million acres will receive treatments across the Great Basin Landscape Conservation Cooperative (GBLCC) to conserve greater sage-grouse habitat over the next decade. These treatments are intended to restore native sagebrush habitat by reducing encroachment of juniper, infestations of invasive weeds, and wildfire. This project will evaluate the effects of vegetation treatments on population connectivity, genetic diversity and gene flow of wildlife species across the full extent of the Great Basin Landscape Conservation Cooperative.

Where the wild things are: A research agenda for studying the wildlife-wilderness relationship

Publications Posted on: May 27, 2016
We explore the connection between US designated wilderness areas and wildlife with the goal of establishing a research agenda for better understanding this complex relationship. Our research agenda has two components. The first, "wildlife for wilderness," considers the impact of wildlife on wilderness character.

Birds of Southwestern grasslands: Status, conservation, and management

Publications Posted on: May 12, 2016
In the Southwestern United States, the grassland avifauna is collectively composed of a mixture of species found primarily in desert grasslands, shortgrass steppe, wet meadows, and alpine tundra (as used here, desert grasslands incorporate both arid grasslands and desert shrub grasslands). Of these habitats, desert grasslands and shortgrass steppe are the most extensive and support the greatest number of grassland bird species.

Countering misinformation concerning big sagebrush

Publications Posted on: May 12, 2016
This paper examines the scientific merits of eight axioms of range or vegetative management pertaining to big sagebrush. These axioms are: (1) Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) does not naturally exceed 10 percent canopy cover and mountain big sagebrush (A. t. ssp.
