Quercus is one of the most abundant and economically important genera of woody plants in
the Northern Hemisphere. To infer phylogenetic relationships within Quercus subgenus …

The setting of conservation priorities within species requires explicit goals and identification
of the appropriate targets for conservation. I suggest that the conservation goal should be to …

The spatial distribution of genetic markers can be useful both in estimating patterns of gene
flow and in reconstructing biogeographic history, particularly when gene genealogies can …

Phylogeography has become a powerful approach for elucidating contemporary
geographical patterns of evolutionary subdivision within species and species complexes. A …

The rapid development of molecular techniques offers a palette of technical approaches for
population biologists interested in a wide range of questions. For example, these tools can …
