Translocation and deterrence as tools for conservation and management of Columbian ground squirrels (Urocitellus columbianus) in a national park

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Our study evaluates two non‐lethal methods for managing Columbian ground squirrels in Jasper National Park, Alberta, Canada. We demonstrate that translocated squirrels exhibited lower survival than controls and that a deterrence methodology that includes blocking burrows may be an appropriate alternative, especially when combined with other tools ...

Potential Causes of Shedding Aggregations in Prairie Rattlesnakes

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The mechanisms that underpin aggregation behavior in animals—and the cues that elicit it—inform our understanding of how animals resolve tradeoffs among selection pressures. We documented aggregation during ecdysis in a population of asynchronously shedding prairie rattlesnakes (Crotalus viridis) and tested predictions generated from the four ...
