Abstract A combination of climatic and environmental factors influences, and potentially guides, certain life-history processes, such as breeding. Sea turtle females may wait offshore for the optimal conditions to nest, but these environmental cues remain mostly unknown. Our aim was to identify climatic and tidal influences on nesting for leatherback turtles (Dermochelys coriacea) and try to find any specific conditions that induced them to abort the nesting attempt. To assess these issues, the beach in Pacuare Nature Reserve, on the Caribbean Costa Rica, was monitored from 2010 to 2015. Models showed that high atmospheric pressure and wind speed favoured nesting but high rainfall discouraged successful nesting; high and low tides were negatively correlated with nesting, suggesting that turtles avoid nesting when tidal cycles reach their extremes. Overall, climatic features likely related to storm episodes, and extreme tidal ranges, appear to influence leatherbacks' nesting behaviour. Therefore, the steady increase in intense storm occurrence predicted by climatic projections might represent an additional obstacle to the survival of this species.

气候和潮汐对海龟筑巢行为的影响

摘要 气候和环境因素的结合会影响并可能指导某些生命历史过程，例如繁殖。海龟雌性可能会在海上等待最佳条件筑巢，但这些环境线索大多仍是未知数。我们的目标是确定气候和潮汐对棱皮龟 (Dermochelys coriacea) 筑巢的影响，并试图找到导致它们中止筑巢尝试的任何特定条件。为了评估这些问题，从 2010 年到 2015 年对加勒比海哥斯达黎加 Pacuare 自然保护区的海滩进行了监测。模型表明，高气压和风速有利于筑巢，但高降雨量阻碍了成功筑巢；高潮和低潮与筑巢呈负相关，这表明海龟在潮汐周期达到极端时会避免筑巢。总体而言，可能与风暴事件和极端潮汐范围相关的气候特征似乎会影响棱皮龟的筑巢行为。因此，气候预测预测的强风暴发生的稳定增加可能代表该物种生存的额外障碍。
