Sampling design and bias in DNA-based capture-mark-recapture population and density estimates of Grizzly Bears
Article Abstract:
Two sampling designs were assessed over a 3-year period for estimating the population size of grizzly bears (Ursus arctos), using the DNA capture-mark-recapture methods in British Columbia, Canada. The trade-off between intensive sampling to ensure robustness and the adequate precision of estimators is illustrated.

Estimating Grizzly bear distribution and abundance relative to habitat and human influence
Article Abstract:
Factors that influence and predict grizzly bear distribution are discussed. The evaluation of relationship of grizzly bears detections with landscape variables of habitat and human activity is also highlighted.
