Why did the bear cross the road? Comparing the performance of multiple resistance surfaces and connectivity modeling methods

Publications Posted on: September 20, 2016
There have been few assessments of the performance of alternative resistance surfaces, and little is known about how connectivity modeling approaches differ in their ability to predict organism movements. In this paper, we evaluate the performance of four connectivity modeling approaches applied to two resistance surfaces in predicting the locations of highway crossings by American black bears in the northern Rocky Mountains, USA.

Wildlife dispersal ability and landscape connectivity in the northern Rocky Mountains

Science Spotlights Posted on: October 14, 2015
Increasing human populations have fueled urban development and land conversion, causing substantial loss and fragmentation of wildlife habitat. Researchers evaluated conditions for 108 different species across a large portion of the Northern Rockies in order to predict current and potential future patterns of fragmentation, prioritize keystone corridors for protection and enhancement, and identify which species in which places might require habitat restoration or assisted migration.

Evaluating the intersection of a regional wildlife connectivity network with highways

Publications Posted on: October 02, 2014
Reliable predictions of regional-scale population connectivity are needed to prioritize conservation actions. However, there have been few examples of regional connectivity models that are empirically derived and validated.

Detecting genotyping errors and describing black bear movement in northern Idaho

Publications Posted on: December 12, 2012
Non-invasive genetic sampling has become a favored tool to enumerate wildlife. Genetic errors, caused by poor quality samples, can lead to substantial biases in numerical estimates of individuals.
