沿海植被生态系统是世界上受到威胁最严重的生态系统之一，面临着多种人为压力。海草就是一个很好的例子，它支持碳捕获、海岸稳定和生物多样性，但在全球范围内正在以惊人的速度下降。为了了解这些生态系统变化的原因和后果，我们需要确定不同生物和非生物成分之间的联系。我们使用了由公民科学家在英国南海岸300公里范围内收集的关于Zostera marina海草的数据作为案例研究。我们收集了有关海草基因型、表型、动物群和相关水深、光照、海面温度、波浪和洋流能量的数据，以验证有关温带潮下生态系统分布和多样性的假设。我们发现了群体遗传学的空间结构，通过基因型的局部分类和在更广泛的地理尺度上的距离隔离来证明。通过将我们的分子数据与海草表型和动物的信息相结合，我们证明了这些生态系统成分主要是通过共同环境因素的影响间接联系在一起的。在一项研究中检查基因型、表型和环境数据是不寻常的，但这种方法可以为海草的保护和恢复提供信息，并为广泛而重要的生态系统提供新的见解。
Coastal vegetative ecosystems are among the most threatened in the world, facing multiple anthropogenic stressors. A good example of this is seagrass, which supports carbon capture, coastal stabilization, and biodiversity, but is declining globally at an alarming rate. To understand the causes and consequences of changes to these ecosystems, we need to determine the linkages between different biotic and abiotic components. We used data on the seagrass, Zostera marina, collected by citizen scientists across 300 km of the south coast of the United Kingdom as a case study. We assembled data on seagrass genotype, phenotype, infauna, and associated bathymetry, light, sea surface temperature, and wave and current energy to test hypotheses on the distribution and diversity of this temperate sub-tidal ecosystem. We found spatial structure in population genetics, evident through local assortment of genotypes and isolation by distance across a broader geographic scale. By integrating our molecular data with information on seagrass phenotype and infauna, we demonstrate that these ecosystem components are primarily linked indirectly through the effects of shared environmental factors. It is unusual to examine genotypic, phenotypic, and environmental data in a single study, but this approach can inform both conservation and restoration of seagrass, as well as giving new insights into a widespread and important ecosystem.
