基于组合物种分布模型的海州湾矛尾虾虎鱼空间分布特征及其影响因素研究
Spatial distribution of Chaeturichthys stigmatias and influence factors in Haizhou Bay based on ensemble species distribution model
摘要
Abstract
The spatial distribution of species can reflect the interrelationships among individuals,which are the result of long-term adaptation and selection between species and the environment.This has a significant impact on the development and resource utilization of species.This study constructed 10 species distribution models based on the samples collected from the bottom trawl surveys in Haizhou Bay and adjacent waters during springs and autumns of 2013-2022.We selected models with better performance and prediction accuracy to construct an ensemble species distribution model(ESDM)based on the true skill statistic and area under the receiver operator characteristic(ROC)curve.We analyzed the spatial distribution of Chaeturichthys stigmatias and the influencing factors.The results showed that ESDM could effectively reduce the uncertainty of single-species distribution models,improve the accuracy of model prediction,and analyze the spatial distribution characteristics of C.stigmatias in Haizhou Bay with higher accuracy.C.stigmatias generally concentrated in the western coastal and southern waters of Haizhou Bay during the spring seasons of 2013-2022,with lower distribution in the eastern,central,and northern waters.The longitude and latitude deviation ranges of the distribution center during this period were approximately 1°.C.stigmatias were mainly distributed in the southwestern area of Haizhou Bay during autumn,with the distribution center moving slightly.Additionally,we found that water depth,prey density,sea bottom temperature,and sea bottom salinity were significantly correlated with the spatial distribution of C.stigmatias in Haizhou Bay,of which prey density generated the greatest effect in spring,and water depth generated the greatest effect in autumn.This study analyzed the spatial distribution characteristics and changes in the distribution centers of C.stigmatias on a regional scale and explored seasonal differences in important influencing factors.This study provides basic information for sustainable utilization of C.stigmatias.关键词
