– researchers from Guangdong and Hong Kong analysed genetic material from finless porpoises of the Pearl River Estuary and other geographic locations. Based on their results, they argue that the group which finless porpoises belong to originated in tropical waters closer to Southern China rather than in more northern locations. (Kuntong Jia, Wenzhi Lin, Duan Gui, Leszek Karczmarski, Yuping Wu, 2014. Molecular evidence reveals the distinctiveness of Indo-Pacific finless porpoises (Neophocaena phocaenoides) in the Pearl River Estuary and insights into genus Neophocaena’s origin.

– researchers at the Swire Institute for Marine Science investigated the mating behaviour of the mangrove snail and found that the males preferentially select larger females and larger males beat smaller males to the big females.

– researchers from China, Canada and Hong Kong investigated the accumulation of the flame retardant chemical BDE-47 in zebra fish. They found male zebra fish accumulate more of the chemical in their livers than females and that females pass on the chemical to their eggs.
