Ecotransology : integrated design for urban mobility
… awareness that bonds the disciplines of road ecology, urban design, transportation planning, automotive engineering, and energy consultation. This work establishes the theoretical foundations for Ecotransology in four parts. Part one, Ideation, is a survey of visions on cities …

Effects of Road Characteristics, Land Cover, and Topography on Roadkill Patterns Across a Rural-Urban Gradient in Southwest Virginia
Roads are one of the most recognizable artifacts of human habitation and development. They cross various landscapes and expand with the increasing density of human settlements. While these structures are vital in facilitating vehicular transportation, they can also have unintended negative …

ACCEPTANCE OF WILDLIFE CROSSING STRUCTURES ON US HIGHWAY 93 MISSOULA, MONTANA
… substantial mitigation measures along roadways in an attempt to reduce wildlife-vehicle collisions and to provide for safe crossing opportunities for wildlife. Wildlife-specific crossing structures are now increasingly considered in road construction. Reconstruction projects and a range …

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
<p>Roads often 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 …

Influence Of Landscape On Gene Differentiation In The American Pika (Ochotona princeps) Within The Interstate 90 Snoqualmie Pass Corridor
Understanding the impact of different landscape features on the movement of genes among populations can be helpful in managing wildlife populations. Our study used GIS tools to compare genetic connectivity among 13 American pika (<em>Ochotona princeps</em>) habitat patches across an approximately …

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 …

Occupancy of Stream-Associated Amphibians within the Interstate 90 Snoqualmie Pass Corridor
Detection of stream-associated amphibians in visual encounter surveys is challenging due to their cryptic nature; however, occupancy models were developed to deal with these detectability problems and provide estimates of occupancy that can also be related to site characteristics. Highway crossing …

Small mammal microhabitat use and species composition at a wildlife crossing structure compared with nearby forest
… (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, few studies have evaluated their use of WCS. This study was conducted …

Variations of Wildlife Safety Crossings and Their Effects for Mule Deer in Northeast Nevada
… may become unavailable (Forman et al. 2003). Roads are one anthropogenic factor that can create barriers to movement by species, span over 6.4 million kilometers, and cover over 1 % of the total land cover in the United States (Beckman et al. 2010). Roads also are a leading cause of habitat …
