“…300 days) to future ocean conditions, females did not lay any eggs (Table 5). Under control conditions, six females laid 1525 ± 269 eggs each, which matches previous estimations (Mardones et al 2020). An explanation could be that energetic demands at high T°/pCO 2 are as high in exposed females to only invest energy in maintenance rather than reproduction.…”

Global average temperatures and seawater pCO2 have rapidly increased due to the oceanic uptake of atmospheric carbon dioxide producing severe consequences for a broad range of species. The impacts on marine ectotherms have been largely reported at short-term scales (i.e. from days to weeks); however, the prolonged effects on long-term processes such as reproduction have received little attention. The gastropod Ocenebra erinaceus is a key predator structuring communities on rocky shores of the French and UK coasts. Even though rocky shore species are regarded as being very tolerant to changes in temperature and pH, many of them are living near their upper tolerance limits, making them susceptible to rapid environmental changes. Here, we report that future mean seawater conditions (RCP8.5, + 3 °C and ~ 900 μatm CO2) do not significantly affect the physiology and molecular response of O. erinaceus adults after 132 days. During the first 50 days, there was a slight impact on oxygen consumption rates and body weight; however, after 95 days of exposure, gastropods fully acclimated to the experimental condition. Despite this, reproduction in females exposed to these future seawater conditions ceased after long-term exposure (~ 10 months). Therefore, in the short-term, O. erinaceus appear to be capable of full compensation; however, in the long-term, they fail to invest in reproduction. We conclude studies should be based on combined results from both short- and long-term effects, to present realistic projections of the ecological consequences of climate warming.

“…10-months) to future ocean conditions, females did not lay eggs under future ocean conditions. Under control conditions, six females laid 1525 ± 269 eggs each, which is coincident with previous estimations (Mardones et al, 2020). A possible explanation for this result could be that energetic demands of life under future conditions were so high that females exposed to high T°/pCO 2 only invested energy in survival instead of reproduction.…”

Global average temperatures and sea water pCO2 have rapidly increased due to the oceanic uptake of atmospheric carbon dioxide producing severe consequences for a broad range of species. The impacts on marine ectotherms have been largely reported at short-term scales (i.e. from days to weeks); however, the prolonged effects on long-term processes such as reproduction have received little attention. The gastropod Ocenebra erinaceus is a key predator structuring communities on rocky shores of the French and UK coasts. Even though rocky shore species are regarded as being very tolerant to changes in temperature and pH, many of them are living near their upper tolerance limits, making them susceptible to rapid environmental changes. Here, we report that future mean sea water conditions (RCP8.5, + 3°C and ~ 900 µatm CO2) do not significantly affect the physiology and molecular response of O. erinaceus adults after 132 days. During the first fifty-days, there was a slight impact on oxygen consumption rates and body weight; however, after ninety-five days of exposure, gastropods relied on food resources to fully acclimate to the experimental condition. Despite this, it was after long-term exposure (~ 10 months) reproduction ceased in females exposed to these future sea water conditions. Therefore, in the short-term O. erinaceus appear to be capable of full compensation; however, in the long-term, they fail to invest in reproduction. Future research should take into account the combined results from both, short- and long-term effects to improve our projections of the ecological consequences of climate change.

“…We found that the thermal response of early stages of Ocenebra erinaceus was influenced by local thermal conditions that they experienced during the intracapsular development, which led to intraspecific differences in their thermal limits and optimum temperatures. These differences could be a result of physiological and genetic adaptions to local environmental conditions (Mardones et al, 2020b); however, from our results we cannot rule out possible influences of phenotypic effects.…”

“…Embryos from the southern population showed higher respiration rates and metabolic adjustment to elevated temperatures; however, embryos from the northern population showed no metabolic adjustment, high capsular mortalities and limited acclimation to high temperatures (Mardones et al, 2020). In addition, a transplant study conducted on the same populations by Mardones et al (2020b) demonstrated that there are adaptive cost to live under their natal conditions, resulting in trade-offs between reproductive trait. Embryos transferred from the southern to the northern location showed poor performance and high mortality under the northern conditions; which suggests that O. erinaceus is locally adapted to natal conditions.…”
