Identifying ecosystems resilient to climate and land-use changes is recognized as essential for conservation strategies. However, wetland ecosystems may respond differently to stressors depending on their successional state and the strength of ecohydrological feedbacks resulting in fluctuations in habitat availability and suitability. Long-term habitat suitability is necessary for the persistence of wetland-dependent species and a key characteristic of climatic refugia. In the present article, we review and synthesize biogeochemical, thermal, ecological, and hydrological feedbacks and interactions that operate within wetlands and, consequently, regulate overwintering suitability for many freshwater turtles and snakes. We propose that understanding the breadth and interconnected nature of processes controlling temperature, dissolved oxygen, and water table position are vital for the conservation of northern reptile populations that depend on wetlands to survive winter conditions. Finally, we suggest that our integrated framework can guide future research and the management of wetland ecosystems in an era of unprecedented change.

爬行动物越冬栖息地适宜性的主要驱动力:整合湿地生态水文学和空间复杂性

确定对气候和土地利用变化具有适应力的生态系统对于保护战略至关重要。但是,湿地生态系统对压力源的演替状态和生态水文学反馈的强度可能会导致对栖息地可用性和适应性的波动,因此对压力源的反应可能有所不同。长期的生境适应性对于依赖湿地的物种的持久存在和气候避难所的关键特征是必不可少的。在本文中,我们回顾并综合了在湿地内进行的生物地球化学,热,生态和水文反馈和相互作用,并因此调节了许多淡水龟和蛇的越冬适应性。我们建议理解控制温度,溶解氧的过程的广度和相互联系的性质,水位和水位对于保护依靠湿地生存以应付冬季条件的北部爬行动物种群至关重要。最后,我们建议,我们的综合框架可以在一个前所未有的变化时代指导未来的研究和湿地生态系统的管理。
