In species presenting long intervals between reproductive seasons, atmospheric-oceanic phenomena can affect the yearly number of individuals that become reproductively active. Sea turtles take multiyear intervals between reproductive seasons, which are influenced by environmental processes affecting their nutrition. Atmospheric-oceanic phenomena affect the reproductive output of different sea turtle species and populations. The population of green turtles (Chelonia mydas) nesting at Tortuguero-10.4489° N, 83.5069° W-, Costa Rica, is the largest in the Atlantic Basin and one of the most comprehensively studied. Nevertheless, only one study analyzed the effects of sea surface temperature on the reproductive output of Tortuguero green turtles. We analyzed three decades of data that revealed two likely scenarios: (1) more green turtle clutches were laid at Tortuguero after warm sea surface temperature anomalies during boreal winters and (2) fewer green turtle clutches were laid at Tortuguero 2 years after El Nino and more green turtle clutches were laid 2 years after La Nina events. Atmospheric-oceanic phenomena affect green turtle reproductive output likely through disrupting nutritional pathways, which alters the number of female green turtles that become reproductively active each year. Tortuguero green turtles are herbivorous feeding mostly on seagrass meadows off Nicaragua. As primary consumers, green turtles are tightly constrained by environmental conditions, and if the productivity of seagrass meadows decreased due to elevated sea surface temperature in the Caribbean basin or the altered hydric regime following El Nino events, fewer females would be able to accrue energy for reproduction.

厄尔尼诺南方涛动和当地海洋温度对在哥斯达黎加托尔图格罗筑巢的绿海龟（Chelonia mydas）繁殖产量的影响

在繁殖季节间隔很长的物种中，大气-海洋现象会影响每年繁殖活跃的个体数量。海龟的繁殖季节间隔多年，这受到影响其营养的环境过程的影响。大气-海洋现象影响不同海龟物种和种群的繁殖能力。栖息在哥斯达黎加 Tortuguero-10.4489° N, 83.5069° W- 的绿海龟种群 (Chelonia mydas) 是大西洋盆地中最大的种群，也是研究最全面的种群之一。然而，只有一项研究分析了海面温度对 Tortuguero 绿海龟繁殖能力的影响。我们分析了三个十年的数据，揭示了两种可能的情况：(1) 在北方冬季温暖的海面温度异常之后，托尔图格罗放置了更多的绿海龟离合器；(2) 厄尔尼诺现象发生 2 年后在托尔图格罗放置了更少的绿海龟离合器，而在拉尼娜事件后 2 年放置了更多的绿海龟离合器. 大气海洋现象可能通过破坏营养途径来影响绿海龟的繁殖产量，这可能会改变每年繁殖活跃的雌性绿海龟的数量。Tortuguero绿海龟是食草动物，主要以尼加拉瓜附近的海草草地为食。作为主要消费者，绿海龟受到环境条件的严格限制，如果海草草地的生产力因加勒比海盆地海面温度升高或厄尔尼诺事件后水力状况改变而下降，
