描述幼虫的扩散模式对于了解海洋集合种群的生态和进化动态至关重要。最近的研究测量了种群内的局部扩散，但根据经验数据开发海洋扩散核心仍然是一个挑战。基于海景结构是已实现扩散模式的主要预测因子的假设，我们提出了一个框架，它超越了扩散的点估计，转向了简单的扩散核的近似。以珊瑚礁鱼类Elacatinus Lori为研究生物，我们使用遗传亲缘分析在小空间尺度上估计自我招募(
Characterizing patterns of larval dispersal is essential to understanding the ecological and evolutionary dynamics of marine metapopulations. Recent research has measured local dispersal within populations, but the development of marine dispersal kernels from empirical data remains a challenge. We propose a framework to move beyond point estimates of dispersal towards the approximation of a simple dispersal kernel, based on the hypothesis that the structure of the seascape is a primary predictor of realized dispersal patterns. Using the coral reef fish Elacatinus lori as a study organism, we use genetic parentage analysis to estimate self-recruitment at a small spatial scale (
