Species diversity and habitat preference of bdelloid rotifers in the Weizhou island,Guangxi
The island habitat and biological community composition are unique,but there are few reports on the island bdelloid rotifers.During 2021-2022,we investigated seven different habitats,i.e.,moss,soil,leaf litters of bamboo,pine and other,petiolate plant petals and burned leaf stems,in the Weizhou island,Guangxi,to investigate species diversity and habitat preference of bdelloid rotifers.In the Weizhou island,a total of 53 species of bdelloid rotifers in three families,eight genera and 53 species were recorded,of which three species were newly found in China.The results showed that the species diversity of bdelloid rotifers in the island was high(accounting for 10.6%of the global reported bdelloid rotifer species).There was significant difference in species richness among the first four habitats(p<0.0001),and the difference of species composition between different habitats is significantly greater than that within the same habitat(p = 0.001).The habitat preference of bdelloid rotifer is obvious.In addition,IndVal index analysis showed that 10 rotifer species had significant preference for special habitats.In the future,we should strengthen the investigation of island habitats,especially rare habitats,for the purpose of finding more species of bdelloid rotifers and enriching their geographical distribution in China.
