The October issue of Current Biology will feature an article entitled “Roads threaten Asiatic cheetahs in Iran,” about the impacts of wildlife vehicle collisions on the endangered species (there are fewer than 50 free roaming cheetahs in the country). The authors reached out to WTI Research Ecologist Marcel Huijser to provide input and assistance on the road ecology components, and they recently contacted WTI to acknowledge Marcel’s “invaluable comments.” The final article is available online.
Road Ecology Researcher Marcel Huijser and his colleagues have a newly published journal article in Biological Conservation. “A fence runs through it: A call for greater attention to the inﬂuence of fences on wildlife and ecosystems” is one of the first empirical investigations of the interactions between fences, wildlife, ecosystems, and societal needs. It illustrates the global prevalence of fencing, outlines fence function and common designs, reviews the pros and cons of fencing relative to wildlife conservation, and identifies knowledge gaps and research needs in fence ecology. The full article is available at online.

A team of Montana-based fish passage researchers continue to produce notable results using the outdoor experimental flume at the Bozeman Fish Technology Center. Northwest Science has published the journal article “Sprint Swimming Performance of Shovelnose Sturgeon in an Open-Channel Flume.” The article, authored by Luke Holmquist of MSU’s Department of Ecology, Kevin Kappenman of the US Fish and Wildlife Service, Matt Blank of WTI, and Matt Schultz highlights research to study the swimming abilities of wild shovelnose sturgeon in fish passage structures. The results indicate that their swimming abilities have been underestimated in the past. These findings will help improve future designs of fish passage structures and facilitate efforts to prevent habitat fragmentation for this species.
The research is a collaboration among WTI, the MSU Department of Ecology, and the U.S. Fish and Wildlife Service, and one of several projects the partners have conducted together. More information about the sturgeon project is available on the project page and more information about the collaborative research program is available on the MSU Fish Passage webpage.

WTI Research Scientist Tony Clevenger has co-authored a journal article on the impacts of road expansion on cheetah populations. In June, the Journal for Nature Conservation will publish “Road expansion: A challenge to conservation of mammals, with particular emphasis on the endangered Asiatic cheetah in Iran.” The article summarizes a study to identify hotspot locations along an extremely high-risk road for mammals in northeast Iran (Touran Biosphere Reserve [TBR]) and proposes mitigation measures for mammals such as the Asiatic cheetah and Persian gazelles. The full article is currently available on the Science Direct website.

A peer-reviewed study of wildlife crossing structures used by grizzly bears has revealed usage patterns that may help re-connect populations and support conservation efforts. The Wildlife Society Bulletin has published “Road Mitigation is a Demographic Filter for Grizzly Bears,” by Adam Ford, Mirjam Barrueto, and WTI’s Tony Clevenger, based on research that investigated five crossing structure designs installed at 44 sites along the Trans-Canada Highway in Banff National Park. Using both tracking data and camera images, the research team compared usage of the five types of structures between single bears and family groups of bears. While single bears used both tunnels and overpasses, grizzly females traveling with cubs showed a strong preference for overpasses. The study was featured last week on the University of British Columbia website and highlighted today on Science Daily. The full journal article is available in the online edition of the Wildlife Society Bulletin.
Frontiers in Ecology and Evolution has published “Performance of Arch-Style Road Crossing Structures from Relative Movement Rates of Large Mammals,” authored by A.Z. Andis (University of Montana/Yale University), Marcel Huijser of WTI, and Len Broberg (University of Montana). The team measured the movements of large mammal species at 15 wildlife underpasses on U.S. Highway 93 in Montana, documenting findings for several species including white-tailed deer, mule deer, black bear and coyote.

Fish passage research by a Bozeman-based team will soon be published in Northwest Science. The journal has accepted “Sprint Swimming Performance of Shovelnose Sturgeon in an Open-Channel Flume,” authored by Luke Holmquist of MSU’s Department of Ecology, Kevin Kappenman of the US Fish and Wildlife Service, Matt Blank of WTI, and Matt Schultz. The article describes research in an outdoor experimental flume at the Bozeman Fish Technology Center. The sprint velocities from the laboratory study indicate that the swimming capability of shovelnose sturgeon has been previously underestimated. The results of this study provide data that might support design and analysis of fish passage projects for shovelnose sturgeon and other sturgeon species.

WTI safety researchers Ahmed Al-Kaisy, Levi Ewan, and graduate student Fahmid Hossain have published a study on safety improvements for low-volume roads. For “Economic feasibility of safety improvements on low-volume roads,” the research team investigated 27 safety improvements commonly used on high volume roads, and determined that appoximately half would also also be cost-effective to implement on roads with low traffic volumes.

Researchers from the Center for Health and Safety Culture have published a study in Transportation Research regarding driving under the influence of cannabis. “Cultural predictors of future intention to drive under the influence of cannabis (CUIC)” was authored by Nic Ward, Jay Otto, William Schell, Kari Finley and their research partners. In addition to identifying predictors, the article identifies strategies to address cultural perceptions about driving after using cannabis that may be effective in reducing these driving behaviors.
