We also outline how to construct alternative covariance models for the analysis of geographical variation that are both mathematically well behaved and easily implementable.

Several lines of evidence suggest that some of the observed differences are adaptively relevant, but rigorous tests of local adaptation or the link between specific phenotypes and fitness are sorely lacking. Evidence for a role of altitudinal adaptation also exists for a number of candidate genes, most prominently haemoglobin, and for anonymous molecular markers.

An in-depth look at the death of a Duquesne University adjunct professor suggests that the University (and its associated community) did more to try and help her than has been credited—but it also reemphasizes what a lousy deal adjunct positions can be.
