| 2 | Diversity,endemism and conservation of the freshwater crabs of China(Brachyura:Potamidae and Gecarcinucidae)显示文摘China lies at the heart of the global center of freshwater crab diversity in tropical Asia,where the 2 most diverse families occur:Potamidae(505 species,95 genera)and Gecarcinucidae(344 species,59 genera).China stands out as the country with the highest species richness of freshwater crabs globally.Its fauna comprises 243 species in 37 genera and in 2 families,and species discovery is still progressing at a rapid pace.The vast majority of the species are distributed in southwest,south central and eastern China in the Oriental zoogeographical region.China also stands out as having a highly endemic freshwater crab fauna at the species level(96%)and at the genus level(78%).Although the recent International Union for the Conservation of Nature(IUCN)red list conservation assessment found only 6 out of 228 species(2%)to be threatened(5 potamids and 1 gecarcinucid),the majority(more than 75%)of Chinese species are regarded as data deficient,so the number of threatened species is likely to be a serious underestimate.Threats from increasing habitat destruction and pollution are a major concern due to the rapidly growing economy and massive developments taking place in China.There is therefore an urgent need for increased species exploration and for the development of a conservation strategy for China’s threatened(and potentially threatened)endemic freshwater crab species. | Neil CUMBERLIDGE Peter K.L.NG Darren C.J.YEO Tohru NARUSE Kirstin S.MEYER Lara J.ESSER | 2011 | Integrative Zoology2011，6，1： | 0 |
