The role of behavior and microhabitats on the physiology of intertidal benthic invertebrates during heatwaves

Abstract

Heatwaves are climatic events that are associated with abnormally higher temperatures for an extended period. It is expected that they might become more intense, longer, and more frequent in the future. An important model ecosystem for observing the effect of heatwaves in benthic organisms is the rocky intertidal zone. Although many studies are focusing on the effect of heatwaves in coastal organisms, few of them are looking for the role of environmental heterogeneity in this context. The rocky environments microclimate mosaic patter can have enormous influences on physiological performance and survival for most intertidal organisms during climatic issues. Species behavioral adjustments are also important to deal with thermal adverse conditions. Therefore, we aim to assess the role of behavior and microhabitat availability in the physiological performance of two interacting species (predator-prey system) experiencing heatwaves of different magnitude and duration. For such, we will do manipulative experiments in situ, in collaboration with Professor Brian Helmuth's laboratory, one of the best groups of the word in this area. Additionally, this proposal will give me the opportunity to complement and strengthen my postdoctoral research, to expand the investigation of my current research on extreme climatic events in benthic population from rocky shores, to work with an innovative technology by using biomimetic organisms and to strengthen the collaboration between Brazil and USA research institutions, with the potential of new studies to be carried out in the future.
