海洋生物幼虫的扩散规模对海洋保护区网络的设计具有重要意义。我们研究了在一个小岛保护区生产的珊瑚礁鱼幼虫的命运，使用基于母体稳定同位素传递给后代的大量标记方法。大约60%的定居幼鱼在岛上产卵，这些物种的中上层幼虫期短（< 2周）和长（约10 - 1个月）。如果幼虫的出生归巢是一种共同的生活史策略，那么管理和保护珊瑚礁的适当空间尺度可能比以前假设的要小得多。
The scale of larval dispersal of marine organisms is important for the design of networks of marine protected areas. We examined the fate of coral reef fish larvae produced at a small island reserve, using a mass-marking method based on maternal transmission of stable isotopes to offspring. Approximately 60% of settled juveniles were spawned at the island, for species with both short (< 2 weeks) and long (> 1 month) pelagic larval durations. If natal homing of larvae is a common life-history strategy, the appropriate spatial scales for the management and conservation of coral reefs are likely to be much smaller than previously assumed.
