Genetic structure of cetacean populations in sympatry, parapatry, and mixed assemblages: implications for conservation policy
Article Abstract:
Patterns of intraspecific genetic differentiation among cetacean populations in parapatry, sympatry and mixed assemblages within a geographic region were investigated. An analysis of examples of resource specialization in vertebrate species showed that the assemblages can be spatially and temporally dynamic, presenting a special problem for conservation managers when cetacean species are hunted on feeding grounds. Intraspecific foraging specializations might play an important role in limiting gene flow between parapatric and sympatric cetacean populations.

Isolation of microsatellite loci from a social lizard, Egernia stokesii, using a modified enrichment procedure
Article Abstract:
It is has been possible to modify the methods developed by Kandpal and Refseth to isolate tetranucleotide repeat loci from the lizard Egernia stokesii. With a new enrichment technique, microsatellite sequences for both flanking regions can be isolated intact. A number of the loci isolated in E. stokesii were tested to assess their utility in related taxa. It was possible to successfully amplify four loci in closely linked species and genera.
