Cougar density on the Oregon Coast: Using dead recovery modeling in an open population
The Journal of Wildlife Management, EarlyView.The primary objective of this study was to determine cougar density in western Oregon. Our results demonstrate that integrating DNA collected via bio‐darting, mandatory hunter‐harvest check‐ins, and GPS collar data into the OPCR2 is a reliable method for estimating cougar densities in densely forested coastal systems.

Estimating widespread beaver dam loss: Habitat decline and surface storage loss at a regional scale
Ecosphere, 2022 The loss of beaver populations has commonly been accompanied by the failure of beaver dams, leading to stream incision, water table lowering, and the eventual transition from a beaver meadow to a drier riparian corridor.

Evaluating novel attachment methods for tracking devices on terrestrial mammals
The Journal of Wildlife Management, EarlyView.We deployed GNSS tracking devices on 2 endangered large terrestrial mammals, scimitar‐horned oryx and Przewalski's horses, using novel attachment methods. Tags achieved fix success rates and spatial accuracy that compare well with standard collars used on large mammals.

Frontiers in Conservation Science, 2022 Wildlife translocations alter animal movement behavior, so identifying common movement patterns post-translocation will help set expectations about animal behavior in subsequent efforts. American and Eurasian beavers (Castor canadensis; Castor fiber) are

River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...
