Variation in genetic diversity across the range of North American brown bears

Article Abstract:

A study of levels of genetic diversity among North American brown bears was conducted using eight nuclear microsatellite markers that are highly variable. Northern populations had the highest levels of genetic diversity (H sub e=0.76), while the genetic diversity of bears on the Kodiak Archipelago was very low (H sub e=0.26). Results suggest a much smaller effective population size for the brown bears than had been thought.

Effectiveness of a Regional Corridor in Connecting Two Florida Black Bear Populations

Article Abstract:

Research on the Ocala and Osceola black bear populations indicates that the existing regional corridor connecting the two populations is adequate for providing gene flow. However, the corridor's efficacy may be reduced by human development; implications are discussed.

Using genetics to identify intraspecific conservation units: a critique of current methods

Article Abstract:

Genetic criteria proposed by Moritz in 1994 for identifying evolutionary significant units and management units should only be used with caution. Continued discussion and refinement of these ideas will result in more useful criteria.
