海山底栖生物群落分布格局的研究进展OA北大核心

Considering that biodiversity conservation in areas beyond national jurisdiction is a key issue in aca-demia and deep-sea governance,seamounts,which are characterized by both high biodiversity and significant vul-nerability,have been recognized as critical habitats of significant interest for deep-sea biodiversity research and conservation.This review summarizes the important advances and concerns related to the study of seamount ben-thos,the characteristics and controlling factors of community distribution patterns,the prediction of distribution patterns,and the quantitative analyses of the controlling factors.This review also proposes future research topics that should be prioritized,both theoretically and practically.The benthic communities on seamounts exhibit depth zonation along the depth gradient,with biodiversity patterns of single peaks or double peaks or a decline with an increasing depth.In addition,the seamount benthic communities vary along the latitudinal gradient,signifying a significant biogeographic gradient.The complex spatial patterns of these benthic communities are further influ-enced by environmental and biological factors,which include oceanic dynamics that affect larval dispersal,suitable habitats for colonization,and substrate characteristics that support the growth of sessile organisms.
