Phylogeographic and genetic patterns of thermal tolerance: predicting Ozark crayfish population invasiveness, stability, or endangerment.

Duration

September 2009 - June 2012

Narrative

We hypothesize that crayfish in habitats with temperature regimes near the limits of their thermal tolerance will exhibit increased expression of heat shock protein 70 (hsp70). We will investigate the relations between physiological adaptation to thermal stress and phylogeographic patterns in the coldwater crayfish, which may serve as a sensitive indicator species for global climate change. Heat shock protein 70 (hsp70) is highly conserved among animals and is induced by temperature stress (Sørensen et al. 2003). Study results will be integrated with the results of the companion study to enable state agencies to make conservation management decisions based on factors which have been identified with the decline of this species.
