The unprecedented rate of carbon dioxide accumulation in the atmosphere has led to increased warming, acidification and oxygen depletion in the world's oceans, with projected impacts also on ocean salinity. In this perspective article, we highlight potential impacts of these factors on neuronal responses in decapod crustaceans. Decapod crustaceans comprise more than 8,800 marine species which have colonized a wide range of habitats that are particularly affected by global ocean change, including estuarine, intertidal, and coastal areas. Many decapod species have large economic value and high ecological importance because of their global invasive potential and impact on local ecosystems. Global warming has already led to considerable changes in decapod species' behavior and habitat range. Relatively little is known about how the decapod nervous system, which is the ultimate driver of all behaviors, copes with environmental stressors. We use select examples to summarize current findings and evaluate the impact of current and expected environmental changes. While data indicate a surprising robustness against stressors like temperature and pH, we find that only a handful of species have been studied and long-term effects on neuronal activity remain mostly unknown. A further conclusion is that the combined effects of multiple stressors are understudied. We call for greater research efforts towards long-term effects on neuronal physiology and expansion of cross-species comparisons to address these issues.

海洋变化的神经生物学——来自十足目甲壳类动物的见解

大气中二氧化碳前所未有的积累速度导致世界海洋变暖、酸化和氧气消耗加剧,预计还会对海洋盐度产生影响。在这篇观点文章中,我们强调了这些因素对十足目甲壳类动物神经元反应的潜在影响。十足目甲壳类动物包括超过 8,800 种海洋物种,它们定居在广泛的栖息地,这些栖息地尤其受全球海洋变化的影响,包括河口、潮间带和沿海地区。许多十足目物种具有巨大的经济价值和高度的生态重要性,因为它们具有全球入侵潜力和对当地生态系统的影响。全球变暖已经导致十足目物种的行为和栖息地范围发生了相当大的变化。对于作为所有行为的最终驱动力的十足动物神经系统如何应对环境压力源,我们知之甚少。我们使用精选的例子来总结当前的发现并评估当前和预期环境变化的影响。虽然数据表明对温度和 pH 值等压力因素具有惊人的稳健性,但我们发现仅研究了少数物种,并且对神经元活动的长期影响仍然大部分未知。另一个结论是,多重压力因素的综合影响尚未得到充分研究。我们呼吁加大对神经元生理学的长期影响的研究工作,并扩大跨物种比较以解决这些问题。我们使用精选的例子来总结当前的发现并评估当前和预期环境变化的影响。虽然数据表明对温度和 pH 值等压力因素具有惊人的稳健性,但我们发现仅研究了少数物种,并且对神经元活动的长期影响仍然大部分未知。另一个结论是,多重压力因素的综合影响尚未得到充分研究。我们呼吁加大对神经元生理学的长期影响的研究工作,并扩大跨物种比较以解决这些问题。我们使用精选的例子来总结当前的发现并评估当前和预期环境变化的影响。虽然数据表明对温度和 pH 值等压力因素具有惊人的稳健性,但我们发现仅研究了少数物种,并且对神经元活动的长期影响仍然大部分未知。另一个结论是,多重压力因素的综合影响尚未得到充分研究。我们呼吁加大对神经元生理学的长期影响的研究工作,并扩大跨物种比较以解决这些问题。我们发现只研究了少数物种,对神经元活动的长期影响仍然未知。另一个结论是,多重压力因素的综合影响尚未得到充分研究。我们呼吁加大对神经元生理学的长期影响的研究工作,并扩大跨物种比较以解决这些问题。我们发现只研究了少数物种,对神经元活动的长期影响仍然未知。另一个结论是,多重压力因素的综合影响尚未得到充分研究。我们呼吁加大对神经元生理学的长期影响的研究工作,并扩大跨物种比较以解决这些问题。
