产前睾酮（T）从母体向后代的转移是表型可塑性的一个重要来源。在鸟类中，暴露于与生态相关的刺激（如社会竞争或有吸引力的配偶）会使雌鸟在卵黄中沉积更多的睾酮。暴露于升高的卵黄 T 会改变后代的几种体能相关性状的表达（如生长、免疫功能、第二性征和行为）。尽管其中一些变化具有潜在的适应性，但并非所有研究都发现卵黄 T 水平会随着生态相关刺激因素的变化而变化。这种异质性目前还无法解释，限制了我们预测代际间对生态变化反应的能力。在此，我们进行了系统的文献检索，在39个野生物种中发现了119个观察结果，这些观察结果测量了卵黄T分配在各种刺激下的雌性间差异。我们利用机器学习的一种形式--助推回归树来检验物种特异性或研究水平变量的变化是否能解释卵黄T分配的变化（即有统计学意义的反应与无意义的反应）。我们发现，物种特异性和研究水平变量都是预测卵黄T水平显著变化的重要因素。地理范围（纬度和经度）、进化独特性、寿命、相对于雌性质量的卵量、社会性、迁徙状态和羽化时间是 48 个被研究物种中影响最大的前 10 个预测因子。我们还发现，与其他生态环境研究相比，测量或操纵社会刺激（如竞争和繁殖密度）或繁殖日期的研究更有可能发现卵黄T分配的变化。总之，这些数据提供了有关卵黄T分配及其在不同物种和环境中的适应价值的几个可检验的假设。此外，这些发现还有助于我们预测生态变化将如何影响雌性的激素反应，从而影响后代。

The effects of climate change are now more pervasive than ever. Marine ecosystems have been particularly impacted by climate change, with marine heatwaves (MHWs) being a strong driver of mass mortality events. Even in the most optimistic greenhouse gas emission scenarios, MHWs will continue to increase in frequency, intensity and duration. For this reason, understanding the resilience of marine species to the increase of MHWs is crucial to predicting their viability under future climatic conditions.In this study, we explored the consequences of MHWs on the resilience (the ability of a population to resist and recover after a disturbance) of a Mediterranean key octocoral species, Paramuricea clavata, to further disturbances to their population structure. To quantify P. clavata's capacity to resist and recover from future disturbances, we used demographic information collected from 1999 to 2022, from two different sites in the NW Mediterranean Sea to calculate the transient dynamics of their populations.Our results showed that the differences in the dynamics of populations exposed and those not exposed to MHWs were driven mostly by differences in mean survivorship and growth. We also showed that after MHWs P. clavata populations had lower resistance and slower rates of recovery than those not exposed to MHWs. Populations exposed to MHWs had lower resistance elasticity to most demographic processes compared to unexposed populations. In contrast, the only demographic process showing some differences when comparing the speed of recovery elasticity values between populations exposed and unexposed to MHWs was stasis. Finally, under scenarios of increasing frequency of MHWs, the extinction of P. clavata populations will accelerate and their capacity to resist and recover after further disturbances will be hampered.Overall, these findings confirm that future climatic conditions will make octocoral populations even more vulnerable to further disturbances. These results highlight the importance of limiting local impacts on marine ecosystems to dampen the consequences of climate change.
