“…The mechanisms underpinning the hardening responses have been well defined in D. melanogaster and are linked to the upregulation of Hsp70, but changes in Hsp70 expression have not been linked to hardening in other Drosophila species (Krebs, 1999;Hoffmann et al, 2003). These results suggest that the capacity for Hsp70 to act as regulator of heat plasticity may be species-specific (Hamdoun et al, 2003;Ravaux et al, 2016;Willot et al, 2017). Despite plasticity only shifting CT MAX by <0.60°C, mechanistic species distribution models have shown that even a 0.50°C change in CT MAX can contribute to meaningful reductions in projected range losses under climate change (Bush et al, 2016).…”

Understanding the capacity for different species to reduce their susceptibility to climate change via phenotypic plasticity is essential for accurately predicting species extinction risk. The climatic variability hypothesis suggests that spatial and temporal variation in climatic variables should select for more plastic phenotypes. However, empirical support for this hypothesis is limited. Here, we examine the capacity for ten Drosophila species to increase their critical thermal maxima (CT ) through developmental acclimation and/or adult heat hardening. Using four fluctuating developmental temperature regimes, ranging from 13 to 33 °C, we find that most species can increase their CT via developmental acclimation and adult hardening, but found no relationship between climatic variables and absolute measures of plasticity. However, when plasticity was dissected across developmental temperatures, a positive association between plasticity and one measure of climatic variability (temperature seasonality) was found when development took place between 26 and 28 °C, whereas a negative relationship was found when development took place between 20 and 23 °C. In addition, a decline in CT and egg-to-adult viability, a proxy for fitness, was observed in tropical species at the warmer developmental temperatures (26-28 °C); this suggests that tropical species may be at even greater risk from climate change than currently predicted. The combined effects of developmental acclimation and adult hardening on CT were small, contributing to a <0.60 °C shift in CT . Although small shifts in CT may increase population persistence in the shorter term, the degree to which they can contribute to meaningful responses in the long term is unclear.

“…It also may comprise from the induction of many other non Hsps genes. 4,[8][9][10][11] The comparison between Drosophila and mussel Mytilus trossulus showed that in the Drosophila heat shock protein is synthesized during heat stress, but it will only be expressed after stress in mussel Mytilus trossulus. A range of HSPs proteins involved in response to heat were detected by faint SDS-PAGE bands in marine snails, yeast, and mussels.…”

The impact of climate change has been significant to threaten human health via different parameters. Temperature is a dangerous abiotic factor which affects organisms on its ecological level through infiltrating its molecular and cellular levels. Temperature is a measure of the kinetic energy of the molecules in a system. Environmental temperature has direct effect on molecular response and enzymatic activity of animals. This article is a short communication of the effect of the global warming and environmental temperature on the animal's molecular response and enzymatic activity.The effect of the global warming and environmental temperature on the animal's molecular response and enzymatic activity 45 Copyright: ©2020 Alinejad et al.

“…Environmental temperature influences the physiology and ecology of marine organisms across all the stages of their complex life cycles (Storch et al 2009, Hammond and Hofmann 2010, Byrne 2011. It is well-known that temperatures slightly above the optimal can result in negative impacts, including increased ventilation rate and cardiac activity, and can provoke insufficient O 2 supply (Frederich and Pörtner 2000, Harley et al 2006, Metzger et al 2007, Ravaux et al 2016. In many cases, this result in reduced performance and survival at temperatures only slightly above those commonly experienced in the field (e.g., Collin and Chan 2016;Collin et al 2018).…”

Thermal tolerance of the zoea I stage of four Neotropical crab species (Crustacea: Decapoda)

. Although larval stages are often considered particularly vulnerable to stressors, for many marine invertebrates studies of thermal tolerance have focused on adults. Here we determined the upper thermal limit (LT50) of the zoea I of four Caribbean crab species (Macrocoelomatrispinosum, Aratuspisonii, Armasesricordi, and Minucarapax) and compared their thermal tolerance over time and among species. The zoea from the subtidal species M.trispinosum and tree climbing mangrove species A.pisonii had a lower thermal tolerance, 35 and 38.5 °C respectively, than did the semiterrestrial A.ricordi and M.rapax. In all four species tested, the estimates of thermal tolerance depend on the duration of exposure to elevated temperatures. Longer exposures to thermal stress produce lower estimates of LT50, which decreased by ~1 °C from a two- to a six-hour exposure. Crab embryos develop on the abdomen of the mother until the larvae are ready to hatch. Therefore, the thermal tolerances of the embryos which need to coincide with the environmental conditions experienced by the adult stage, may carry over into the early zoea stage. Our results suggest that semiterrestrial species, in which embryos may need to withstand higher temperatures than embryos of subtidal species also produce larvae with higher thermal tolerances. Over the short term, the larvae of these tropical crab species can withstand significantly higher temperatures than those experienced in their marine habitat. Longer term rearing studies are necessary to determine the temperature at which chronic exposure has a negative impact on embryonic and larval survival.
