预测物种的生存能力暴露于日益增加的气候压力，需要了解的机制，支持的成功或失败的边缘人口。而不是传统的长期人口表现的指标，在这里，我们说明，短期（即瞬态）的人口特征，包括阻力，恢复和补偿的措施，是根本的硬珊瑚的极地范围扩大，促进珊瑚种群在高纬度地区的建立。通过对热带和亚热带鹿角珊瑚的年度普查。在2017-2019年期间，我们展示了亚热带珊瑚种群的瞬时扩增潜力如何支持其在不稳定的环境条件下的增强增长。热带和亚热带种群的瞬时动态强烈影响其相应的招聘模式。然而，我们证明两个群体之间菌落存活和片段化模式的差异决定了它们瞬时扩增的相对能力。这种横向变化的瞬间动态的鹿角珊瑚。《珊瑚种群》强调，珊瑚种群可以拥有利用更多可变的边际条件所需的人口可塑性。
Predicting the viability of species exposed to increasing climatic stress requires an appreciation for the mechanisms underpinning the success or failure of marginal populations. Rather than traditional metrics of long-term population performance, here we illustrate that short-term (i.e. transient) demographic characteristics, including measures of resistance, recovery, and compensation, are fundamental in the poleward range expansion of hard corals, facilitating the establishment of coral populations at higher-latitudes. Through the annual census of tropical and subtropical Acropora spp. colonies in Japan, between 2017-2019, we show how the transient amplification potential of a subtropical coral population supports its enhanced growth within unstable environmental conditions. The transient dynamics of both the tropical and subtropical populations were strongly influenced by their corresponding recruitment patterns. However, we demonstrate that variation in colony survival and fragmentation patterns between the two populations determines their relative capacities for transient amplification. This latitudinal variation in the transient dynamics of Acropora spp. populations emphasizes that coral populations can possess the demographic plasticity necessary for exploiting more variable, marginal conditions.
