Assessing a species thermal tolerance through a multiparameter approach: the case study of the deep-sea hydrothermal vent shrimp Rimicaris exoculata.

ABSTRACT: Assessing species thermal tolerance requires identification of their thermal strategies and evaluation of their ability to cope with temperature fluctuations. The mobilization of the molecular heat stress response (HSR), which is a proxy for the thermal tolerance, would be part of the strategy of species colonizing highly variable thermal environments. We here investigate multiple parameters of the HSR in the deep-sea vent shrimp Rimicaris exoculata that colonizes such environments. The set points of the HSR induction, compared to those of the coastal species Palaemonetes varians, clearly reflect a high thermotolerance in this species, while the HSR is proved to be rarely mobilized in the R. exoculata natural populations. Finally, the compilation of multiple parameters such as the upper th
