Microhabitat temperature variation combines with physiological variation to enhance thermal resilience of the intertidal musselMytilisepta virgata

Abstract

1. Predicting the effects of rising temperature entails measuring both habitat thermal characteristics and the physiological variation of the species as it relates to this microhabitat variation; these two types of measurements can generate what

Cardiac performance and heat shock response variation related to shell colour morphs in the mudflat snail Batillaria attramentaria

“…Thus, snails with D type shell may suffer stronger thermal stress than snails with UL type shell in the field. Our findings are similar to previous research in that they demonstrated that ABT of intertidal molluscs inhabiting hot conditions was higher than molluscs inhabiting benign conditions within a population (Moyen et al 2019;Li et al 2021). ABT is not acutely lethal, but does reflect cumulative damage to the cells that is initiated during earlier stages of heating and gradually builds up to a level that causes heart dysfunction at the critical temperature (Han et al 2013;Han et al 2017).…”

“…For intertidal molluscs, ABT is not acutely lethal, but does reflect cumulative damage to the cell during the heating process (Han et al 2013(Han et al , 2017, and is used as a proxy for sublethal (but stress) temperature (Tagliarolo & McQuaid 2015;Dong et al 2022). The differences in ABT reflect their distributions both in a large-scale temperature gradient (Tagliarolo & McQuaid 2015) and microhabitats within site (Li et al 2021), and highlight the critical importance of sublethal effects differences in physiology. At the cellular level, moderate stress induces a set of transcriptomic responses that include the repair of DNA and protein damage, cell cycle arrest or apoptosis, the removal of cellular and molecular debris generated by stress, and an overall transition from a state of cellular growth to one of cellular repairs (Sokolova et al 2012).…”

“…The thermal plasticity of intertidal macrobenthos varies greatly at different spatiotemporal scales in the face of global warming and increasing occurrences of heat wave (Li, Tan, et al, 2021;Zhang et al, 2021). Structural complexity of the habitat could provide microhabitat for intertidal species as "thermal refugia," and micro-scale physiological thermal tolerance can play an important role in determining whether species could survive in the face of extreme events (Li, Tan, et al, 2021;Lima et al, 2016).…”

The accumulation of microscale physiological variations could enhance the macro-scale thermal resilience of intertidal species (Dong et al, 2017;Strain, Cumbo, et al, 2020), and thereby influence species distributional shifts affected by climate change (Bates et al, 2018;Li, Tan, et al, 2021;Liao et al, 2021;Schils & Wilson, 2006).…”

At different time-scales, heat hardening can work synchronously with seasonal acclimatization to increase resistance of raze clam Sinonovacula constricta to high temperatures (Zhang et al, 2020(Zhang et al, , 2021.…”
