庙岛群岛潮间带大型底栖动物群落的季节变化
Seasonal changes in the macrozoobenthic community in the intertidal zones of Miaodao Archipelago
摘要
Abstract
Species composition,dominant species,quantitative distribution,diversity,and community structure of the macrozoobenthic samples collected from the sandy intertidal zones of the 10 islands of Miaodao Archipelago collected in December 2022(autumn),February 2023(winter),and May 2023(spring)were studied.A total of 118 macrozoobenthic species were collected by qualitative and quantitative surveys during the three seasons,with the highest number in spring(57),followed by autumn(45)and winter(39).Mollusks and crustaceans were the main groups.The Miaodao Archipelago intertidal zones were dominated by weakly attached and mobile macrozooben-thos.The five predominant species identified included Pontogeneia littorea,Littorina brevicula,Pharyngocirrus gabriellae,Monodonta labio,and Chlorostoma rustica.The Kruskal-Wallis test indicated no considerable differ-ences in abundance and biomass among seasons and islands.A two-way ANOVA showed that both seasonal and station differences were significant in H',while only seasonal differences were significant in J'.The diversity indi-ces of the southern islands were higher;however,the spatial distribution of abundance and biomass revealed no clear pattern.Cluster analysis and nonmetric multidimensional scaling(NMDS)analysis indicated that the similar-ity of the community structures of the intertidal zones among the 10 islands was low,which may be attributed to the large environmental differences and varying degrees of human impact on the islands.关键词
