Relative effects of habitat loss and fragmentation on population extinction
Article Abstract:
The effects of fragmentation on wildlife population extinction are often confused because fragmentation occurs alongside habitat loss. A simulation model, which allowed both these processes to be varied independently, revealed that the effects of fragmentation are much less than the effects of habitat loss. The suggestion that habitat spatial arrangement can mitigate the effects of habitat loss on species extinction is not valid. Conservation efforts would be better directed at reducing habitat loss and restoring habitats.

Distinguishing tracks of marten and fisher at track-plate stations
Article Abstract:
A quantitative approach to index the populations of uncommon mammals such as the fisher, Martes pennanti and American marten, Martes americana, is presented. The method uses a discriminant function developed using 80 tracks for 21 individuals. Discriminant analysis of the tracks revealed 95 test tracks. The result suggests that baited track stations offer an alternative approach over expensive photographic bait stations for distinguishing tracks of fisher and marten.

Abundance estimators and truth: accounting for individual heterogeneity in wild house mice
Article Abstract:
Several population estimators are applied and compared in calculating wild house mice heterogeneity, including gender and body size. The Chao modified moment estimator demonstrated no bias, and provided confidence intervals that incorporated actual population size.
