Data from: Genetic connectivity for two bear species at wildlife crossing structures in Banff National Park ...
Roads can fragment and isolate wildlife populations, which will eventually decrease genetic diversity within populations. Wildlife crossing structures may counteract these impacts, but most crossings are relatively new, and there is little evidence that they facilitate gene flow. We conducted a thre...

We conducted a three-year research project in Banff National Park, Alberta, to evaluate the effectiveness of wildlife crossings to provide genetic connectivity.

We compared genetic data generated from wildlife crossings with data collected from greater bear populations.
