Utilization of species checklist data in revealing the spatial distribution of fish diversity
2020
Zhang, Qingtian | Hu, Guikun
Marine fish species checklists from six Chinese coastal waters were combined for the analysis of taxonomic diversity. The Genus‐Family index (G‐F index) ranged between 0.39 and 0.84, which generally indicated a decreasing trend with increasing latitude, with the exception of the southernmost area. Average taxonomic distinctness showed a slight increasing trend from northern to central study areas, but whether the taxonomic distinctness indices represent a latitudinal gradient of biodiversity requires further study. The multivariate analysis revealed a distinct latitudinal variation in fish assemblages. These results indicate that species checklist data are helpful in understanding the diversity distribution of fish species in the coastal zone. The potential of a species inventory should be exploited to fully understand biodiversity.
