Dispersal mediates the flow of organisms in meta-communities and subsequently energy and material flows in meta-ecosystems. Individuals within species often vary in dispersal tendency depending on their phenotypic traits (i.e., dispersal syndromes), but the implications of dispersal syndromes for meta-ecosystems have been rarely studied. Using empirical examples on vertebrates, arthropods, and microbes, we highlight that key functional traits can be linked to dispersal. We argue that this coupling between dispersal and functional traits can have consequences for meta-ecosystem functioning, mediating flows of functional traits and thus the spatial heterogeneity of ecosystem functions. As dispersal syndromes may be genetically determined, the spatial heterogeneity of functional traits may be further carried over across generations and link meta-ecosystem functioning to evolutionary dynamics.
扩散介导了生物在复合群落中的流动,进而影响了复合生态系统中的能量和物质流动。同一物种内的个体由于表型特征(即扩散综合征)的不同,其扩散倾向也会有所不同,但扩散综合征对复合生态系统的影响却很少被研究。通过对脊椎动物、节肢动物和微生物的实证案例,我们强调了关键功能特征可以与扩散联系起来。我们认为,这种扩散和功能特征之间的耦合可能会对复合生态系统的功能产生影响,从而调节功能特征的流动,进而影响生态系统功能的空间异质性。由于扩散综合征可能是由遗传决定的,因此功能特征的空间异质性可能会在代际间进一步传递,并将复合生态系统的功能与进化动态联系起来。
