动物的迁徙以及资源的获取和分配为个体行为特征提供了通过种群、社区和生态系统各级生物组织进行传播的机制。分析地球化学的最新发展为生态学家提供了新的机会来研究动物群落的运动和营养动态及其随后对结构和功能的影响。我们将这种方法称为生态地质化学--将地球化学技术应用于种群和群落生态学中的基本问题。我们使用已发表数据的荟萃分析，构建了全球海洋中的δ2H、δ13c、δ15N、δ18O和Δ14c等值线。这些地图显示了区域和海洋盆地尺度上稳定同位素值的巨大空间变异性。我们总结了海洋动物钙化组织中常见的溶解金属的分布。最后对氨基酸和脂肪酸的稳定同位素分析(SIA)进行了综述。这些分析克服了阻碍散装SIA在海洋应用中提供足够的地理或营养分辨率的许多问题。我们预计，生态学家将越来越多地使用生态地球化学方法来估计动物的运动并追踪海洋食物网中的营养途径。这些研究反过来将有助于为海洋环境中基于生态系统的管理战略提供科学依据。
animal movements and the acquisition and allocation of resources provide mechanisms for individual behavioural traits to propagate through population, community and ecosystem levels of biological organization. Recent developments in analytical geochemistry have provided ecologists with new opportunities to examine movements and trophic dynamics and their subsequent influence on the structure and functioning of animal communities. we refer to this approach as ecogeochemistry—the application of geochemical techniques to fundamental questions in population and community ecology. we used metaanalyses of published data to construct δ2H, δ13c, δ15N, δ18O and Δ14c isoscapes throughout the world’s oceans. These maps reveal substantial spatial variability in stable isotope values on regional and oceanbasin scales. we summarize distributions of dissolved metals commonly assayed in the calcified tissues of marine animals. Finally, we review stable isotope analysis (SIa) of amino acids and fatty acids. These analyses overcome many of the problems that prevent bulk SIa from providing sufficient geographic or trophic resolution in marine applications. we expect that ecologists will increasingly use ecogeochemistry approaches to estimate animal movements and trace nutrient pathways in ocean food webs. These studies will, in turn, help provide the scientific underpinning for ecosystembased management strategies in marine environments.
