The purpose of this study was to assess the influence of anthropogenic modification of coastal habitats on fish assemblages in Taiwan, comparing the abundance, species richness and taxonomic composition of fishes on natural v. artificial habitats. While there was no significant variation in the abundance or richness of fishes between natural and artificial habitats, the species composition of fishes in artificial habitats was significantly different from that of natural habitats. Natural reefs were characterized by greater abundance of Stethojulis spp. (Labridae), Abudefduf spp. (Pomacentridae) and Thalassoma spp. (Labridae), whereas anthropogenic habitats were dominated by Parupeneus indicus (Mullidae), Pempheris oualensis (Pempheridae) and Parapriacanthus ransonneti (Pempheridae). In general, it appears that specialist reef-associated species are being replaced with fishes that are much more generalist in their habitat-use. The loss of natural coastal habitats may threaten some species that cannot live in anthropogenically altered habitats, though the overall abundance and diversity of coastal fishes was not significantly different between natural and artificial habitats in Taiwan.
本研究旨在评估人为改变海岸生境对台湾鱼类群落的影响,比较自然生境与人工生境中鱼类的丰度、物种丰富度和分类组成。虽然自然生境和人工生境中鱼类的丰度或丰富度没有显著差异,但人工生境中鱼类的物种组成与自然生境有显著差异。自然礁区以 Stethojulis spp.(雀鲷科)、Abudefduf spp.(雀鲷科)和 Thalassoma spp.(雀鲷科)的丰度较高,而人为生境则以 Parupeneus indicus(石鲈科)、Pempheris oualensis(天竺鲷科)和 Parapriacanthus ransonneti(天竺鲷科)为主。总的来说,似乎与珊瑚礁相关的特有种正在被更多栖息环境较广的鱼类所取代。自然海岸生境的丧失可能会威胁到一些无法在人为改变的生境中生存的物种,尽管台湾的自然生境和人工生境中的沿海鱼类的总体丰度和多样性没有显著差异。
