摘要

近几十年来,气候变化极大地改变了水生生态系统的环境动态,对其中错综复杂的生命平衡产生了深远影响。这篇综述深入探讨了气候变化对水生生物生理的多方面影响,强调温度和盐度是水生环境特有的关键生态因素。全球气温升高及其对淡水和海水栖息地的影响之间错综复杂的关系是本文探讨的基石。气温升高和极端热浪事件频率的增加重塑了鱼类的生存模式,使其超出了最佳温度阈值。此外,这项研究还深入探讨了看似不同的非生物因素之间的相互联系,即温室气体浓度的升高放大了沿海风,催生了沿海上升流。结果--营养丰富但氧气不足的水域--引发了一连串的挑战,导致缺氧状况,对水生生物产生了重大影响。鱼类作为外温动物,对环境波动的适应能力很强,它们的困境得到了强调,同时也揭示了它们对温度变化的易感性。外部温度和内部温度之间的直接相关性因气候引起的波动而加剧,这凸显了应对气候变化对水生栖息地影响的紧迫性。这篇综述揭示了相互关联的环境变化的复杂网络,阐明了它们对水生生物生理的深远影响。它强调了集体努力的必要性,旨在了解和应对不断变化的气候给这些不可或缺的生态系统带来的挑战。

Unraveling the Impact of Climate Change on Fish Physiology: A Focus on Temperature and Salinity Dynamics

Unraveling the Impact of Climate Change on Fish Physiology: A Focus on Temperature and Salinity Dynamics

In recent decades, climate change has significantly altered the environmental dynamics of aquatic ecosystems, profoundly impacting the intricate balance of life within them. This review paper delves into the multifaceted impacts of climate change on the physiology of aquatic life, emphasizing temperature and salinity as pivotal ecological factors unique to aquatic environments. The intricate relationship between rising global temperatures and their repercussions on freshwater and seawater habitats forms the cornerstone of this exploration. Elevated temperatures and escalating frequency of extreme heatwave events have reshaped the paradigm for fish survival, pushing them beyond optimal temperature thresholds. Furthermore, the study delves into the interconnection of seemingly disparate abiotic factors, where heightened greenhouse gas concentrations amplify coastal winds, precipitating coastal upwelling. The consequence—nutrient-rich yet oxygen-deprived waters—fuels a cascade of challenges, inducing hypoxic conditions that significantly impact aquatic organisms. The plight of fish, as ectotherms finely tuned to environmental fluctuations, is underscored, illuminating their susceptibility to temperature variations. The direct correlation between external and internal temperatures, exacerbated by climate-induced fluctuations, accentuates the urgency of addressing climate change’s impact on aquatic habitats. This review disentangles the complex web of interconnected environmental shifts, illuminating their far-reaching repercussions on the physiology of aquatic life. It emphasizes the imperative for collective endeavors aimed at understanding and addressing the challenges imposed by our evolving climate on these indispensable ecosystems.
