Hao, Xiuqing; Shan, Hong; Wu, Caiwen; Zhang, Di; Chen, Bingyao
Biological Trace Element Research (2020)
There has been increasing concern about trace element accumulation in finless porpoises over the past decades, while the long-term variation of its concentration has been little known. Since most soft…
Body contacts and social interactions in captive odontocetes are influenced by the context: An implication for welfare assessment
Serres, Agathe; Hao, Yujiang; Wang, Ding
Animals (2020)
Research on the welfare of captive odontocetes has increased in recent years, but has been mostly focused on bottlenose dolphins (Tursiops truncatus). Few studies investigated potential welfare indicators using quantitative…
