There was no apparent increase in heat-shock survival between heat-pretreated and non-pretreated larvae. There was a positive correlation between the two experimental conditions of heat-shock survival...

Accumulation of HSPs confers thermotolerance in cell cultures and in ectotherms and is an important component of the heat shock response. This response, however, has...

... is below 25°C. The R. exoculata optimal thermal habitat may thus be restricted to values lower than previously expected (<25°C). The heat-shock response is universal, as almost all organims studied to date are able to express heat-shock proteins (hsp; reviewed in Lindquist, 1986 ). Lindquist( 1986...
