ACCEPTANCE OF WILDLIFE CROSSING STRUCTURES ON US HIGHWAY 93 MISSOULA, MONTANA
Wildlife and humans have always interacted on the landscape. However, growing transportation infrastructure and its associated use are causing a large increase in direct and indirect effects on wildlife populations. Humans can also directly be affected, for example, through wildlife-vehicle …

Small mammal microhabitat use and species composition at a wildlife crossing structure compared with nearby forest
… or acting as complete connectivity barriers. Wildlife crossing structures (WCS) can increase the permeability of roads, allowing animals to move safely between habitats. Small mammals are especially vulnerable to the effects of reduced connectivity because of their limited mobility; however, …

IDENTIFYING WILDLIFE CROSSING ZONES FOR THE PRIORITIZATION OF HIGHWAY MITIGATION MEASURES ALONG U.S. HIGHWAY 2: WEST GLACIER, MT TO MILEPOST 193
Highways have been shown to fragment wildlife habitats and populations. In order to mitigate the effects that highways have on wildlife, it is important to assess where wildlife appear to be moving in close proximity to the highway. I surveyed for wildlife trails that approached either side of a …

Are Highways Stressful for Pikas?: Analysis of Stress Hormones of the American Pika (<i>Ochotona princeps</i>) Living Adjacent to Interstate 90 in the Cascade Range of Washington State
… disrupt ecosystem connectivity, harming many wildlife populations. Wildlife crossing structures perforate the barrier-effect of roads, providing safe passage for species dispersing across roads, thereby reconnecting ecosystems. Some wildlife species live in modified habitats along roads and in …

Ecological and Genetic Connectivity of Shrews (Sorex spp.) across Interstate-90 in the Washington Cascade Range
<p>Roads negatively affect wildlife by degrading and fragmenting habitat. The I-90 Snoqualmie Pass East project was established to improve traffic safety for both humans and wildlife. Here, the Washington State Department of Transportation is constructing wildlife crossing structures to increase …

Testing the forage preference of the American pika (Ochotona princeps) for use in connectivity corridors in the Washington Cascades
… of central Washington is to construct nearly 30 wildlife crossing structures along a 15-mile stretch of Interstate-90. American pikas (<em>Ochotona princeps</em>) are being monitored for the SPEP because they have specific habitat requirements and are poor dispersers. Making the crossing …

Ecological Infrastructure: A Framework for Planning and Design: "Addressing Landscape Connectivity and Wildlife Resources for Interstate Highway Systems"
… many roadways were not planned or designed with wildlife in mind. As long linear features in the landscape, interstates can function as landscape barriers and cause significant impacts to adjacent wildlife populations. While an aggressive transportation system is being carried out, researchers …

Variations of Wildlife Safety Crossings and Their Effects for Mule Deer in Northeast Nevada
… component of management and conservation of wildlife in North America. Traditionally, corridors have been viewed as linear strips of habitat that facilitate the movement of organisms through landscapes, but a form of corridor that has been widely accepted over the last several decades are …

Toadal Isolation: Genetic Connectivity of the Western Toad (Anaxyrus boreas) along I-90 in the Snoqualmie Pass Area of Washington State
<p>Single-nucleotide polymorphisms (SNPs) were used to assess the genetic connectivity of western toad (<em>Anaxyrus boreas</em>) breeding populations along Interstate-90 near Snoqualmie Pass, WA. Sites north and south of the freeway were sampled during the breeding season of 2019. SNP loci were …
