Estimating population size of grizzly bears using hair capture, DNA profiling, and mark-recapture analysis
Article Abstract:
The combination of hair removal and DNA analysis offers potential for measuring distribution and abundance of grizzly bears and many other species for which it is possible to obtain tissue samples. This research used DNA analysis to estimate grizzly bear population size in a region of southeast British Columbia, Canada, and a region of southwest Alberta. It was found that capture success can be boosted without any additional financial cost by leaving sites operational for longer, particularly in areas where home ranges are large.

Lynx population dynamics in an untrapped refugium
Article Abstract:
Recent research has looked at the link between lynx population characteristics and snowshoe hare densities in a refugium in the Yukon Territory in the period 1986-1994. Proportions of breeding adults were 100% most years, but were zero in the two years following the decline in hare densities. Yearling females reproduced only in the two years of highest hare numbers. Emigration, which was not sex-biased, peaked annually in the period Mar-Jun.

Using placental scar counts to estimate littersize and pregnancy rate in lynx
Article Abstract:
It had been hypothesized that placental scar count to determine litter size and pregnancy rate of lynx may not be accurate due to inclusion of scars from previous/aborted pregnancies. Accuracy is maximized by comparing in utero with post partum estimates of litter size. Scar shades, which ranged from light brown to black, have been of no significance and may need further research.
