由于海洋吸收大气中的二氧化碳，全球平均温度和海水pCO 2迅速上升，对许多物种造成严重后果。对海洋外温动物的影响主要是在短期范围内（即从几天到几周）报告的;然而，对生殖等长期过程的长期影响很少受到关注。腹足动物Ocenebra erinaceus是法国和英国海岸岩石海岸上构建社区的关键捕食者。尽管岩石海岸物种被认为对温度和pH值的变化非常耐受，但其中许多物种生活在其耐受上限附近，使它们容易受到快速环境变化的影响。在这里，我们报告说，未来的平均海水条件（RCP 8.5，+ 3 °C和~ 900 μatm CO2）不会显着影响O的生理和分子响应。132天后，成鼠。在前50天，对耗氧率和体重有轻微影响;然而，在暴露95天后，腹足类完全适应了实验条件。尽管如此，在长期暴露（约10个月）后，暴露于这些未来海水条件的雌性动物的生殖停止。因此，在短期内，O。刺猬似乎能够完全补偿;然而，从长远来看，它们没有投资于繁殖。我们的结论是，研究应该基于短期和长期影响的综合结果，以提出气候变暖的生态后果的现实预测。
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.
