以前的海景遗传学研究强调洋流和地理距离的作用来解释海洋物种的遗传结构，但底栖栖息地的作用很少被考虑。在这里，我们比较了西太平洋巨蛤种群中观察到的种群遗传结构与模型模拟的栖息地组成和配置，地理距离和洋流。由地理距离确定的扩散提供了一个模拟的遗传结构，更好地与观测比洋流扩散，可能是由于现有的海洋和沿海环流模型的空间分辨率不足。考虑栖息地的组成和配置显着提高了模拟和观察到的遗传结构之间的匹配。这项研究强调了珊瑚礁景观遗传学方法对海洋种群生态学、进化和保护的重要性。
Previous seascape genetics studies have emphasized the role of ocean currents and geographic distances to explain the genetic structure of marine species, but the role of benthic habitat has been more rarely considered. Here, we compared the population genetic structure observed in West Pacific giant clam populations against model simulations that accounted habitat composition and configuration, geographical distance, and oceanic currents. Dispersal determined by geographical distance provided a modelled genetic structure in better agreement with the observations than dispersal by oceanic currents, possibly due to insufficient spatial resolution of available oceanographic and coastal circulation models. Considering both habitat composition and configuration significantly improved the match between simulated and observed genetic structures. This study emphasizes the importance of a reefscape genetics approach to population ecology, evolution and conservation in the sea.
