| Abstract: | - 1.1. Exposing adult salamanders, Eurycea bislineata and Desmognathus ochrophaeus, to heat shocks of 1 hr at 2 or 5°C below Critical Thermhal Maximum (CTM) resulted in the induction of two heat shock proteins (hsps) of approx. Mr 70,000 and 30,000.
- 2.2. Induction patterns in response to similar heat shocks generally differed between the two species.
- 3.3. The milder heat shocks (5°C below CTM) caused different induction patterns than those from the more severe heat shocks, on a tissue-dependent basis. These results indicate that induction of the two hsps is probably independent.
