Analysis and enlightenment of a multispecies case study on the genetic connectivity between the Yellow and the East Seas
摘要
Abstract
The Yellow and the East Seas are important marginal seas in the Pacific Ocean that are characterized by high biodiversity and rich marine resources.However,these Seas are under the dual threat of climate change and human exploitation,thereby causing decreased marine biodiversity.Thus,these seas are in urgent need of protection,and the marine protected area network is effective in preventing or mitigating the negative impacts of the dual pressure on biodiversity.However,connectivity is an important parameter of protected area networks that is diffi-cult to directly measure.Therefore,this study aimed to reveal whether protected areas in the Yellow and the East Seas form a network by examining published reports on genetic connectivity between the two seas.A total of 175 cases were obtained from 137 published reports,and>50%of the cases(65.71%)revealed that there was a signifi-cant genetic differentiation between the Yellow and the East Seas,indicating that the cross-sea populations have low genetic connectivity.Six factors,such as the Yangtze River runoff,spatial distance,habitat heterogeneity,life history(shorter larval duration),ocean currents,and evolutionary processes,hampered the genetic connectivity between the populations from the two seas,whereas ocean currents and life history(longer larval duration)pro-moted genetic connectivity.Furthermore,the analysis revealed that the genetic connectivity between Yellow Sea and East Sea populations was significantly negatively correlated with spatial distance but positively correlated with planktonic larval duration.These results suggest that separate networks of marine protected areas should be con-structed in the Yellow and the East China Seas,and the dispersibility of the protected species and the spatial dis-tance of the protected areas should also be considered during the network design.This study provides a theoretical basis for constructing a network of marine protected areas covering the Yellow and the East Seas,which will aid in the construction of marine protected area networks in other seas.关键词
