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…
Social, reproductive and contextual influences on fecal glucocorticoid metabolites in captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) and bottlenose dolphins (Tursiops truncatus)
Serres, Agathe; Robeck, Todd; Deng, Xiaojun; Steinman, Karen; Hao, Yujiang; Wang, Ding
Journal of Zoological and Botanical Gardens (2020)
Although the use of fecal glucocorticoid metabolite (FGCM) measurements as non-invasive biomarkers for the stress response in mammals has increased, few studies have been conducted in odontocetes. We investigated if…
Social responses of travelling finless porpoises to boat traffic risk in Misumi West Port, Ariake Sound, Japan
Morimura, Naruki; Mori, Yusuke
PLOS ONE (2019)
Anthropogenic effects have created various risks for wild animals. Boat traffic is one of the most fatal risks for marine mammals. Individual behavioral responses of cetaceans, including diving behavior such…
Investigating the distribution of the Yangtze finless porpoise in the Yangtze River using environmental DNA
Tang, Yongkai; Wu, Yunsheng; Liu, Kai; Li, Jianlin; Li, Hongxia; Wang, Qin; Yu, Juhua; Xu, Pao
PLOS ONE (2019)
Determining the distribution of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP) in the Yangtze River has to date relied on traditional visual and counting methods, but such field surveys…
The frequency of solitary behaviours in captive odontocetes is modulated by environmental and social factors
Serres, Agathe; Hao, Yujiang; Wang, Ding
International Journal of Comparative Psychology (2019)
The number of welfare-oriented studies is increasing in animals under human care, including odontocetes. However, validated welfare indicators are lacking for captive odontocetes. We studied the effect of several conditions…
Non-invasive fecal steroid measurements for monitoring the reproductive status of a critically endangered Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)
Hao, Yu-jiang; Nabi, Ghulam; Deng, Xiao-Jun; Wang, Ding
Frontiers in Endocrinology (2019)
Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is a critically endangered freshwater cetacean dwelling in the Yangtze River and its adjoining lakes. Affected mainly by the various anthropogenic activities in this…
A preliminary study on diet of the Yangtze finless porpoise using next‐generation sequencing techniques
Yang, Jiwei; Wan, Xiaoling; Zeng, Xianyuan; Zheng, Jinsong; Han, Yi; Fan, Fei; Hao, Yujiang; Wang, Kexiong; Mei, Zhigang; Wang, Ding
Marine Mammal Science (2019)
...the diet of the Yangtze finless porpoise has been poorly known for a long time because of the lack of studies of stomach contents. Until now, only one study (Chen…
Physical modeling and validation of porpoises’ directional emission via hybrid metamaterials
Dong, Erqian; Zhang, Yu; Song, Zhongchang; Zhang, Tianye; Cai, Chen; Fang, Nicholas X.
National Science Review (2019)
In wave physics and engineering, directional emission sets a fundamental limitation on conventional simple sources as their sizes should be sufficiently larger than their wavelength. Artificial metamaterial and animal biosonar…
Agonistic interactions and dominance relationships in three groups of captive odontocetes: Method of assessment and inter-species/group comparison
Serres, Agathe; Hao, Yujiang; Wang, Ding
Aquatic Mammals (2019)
Social group dynamics are known to impact odontocetes’ health and welfare in captivity. Social dominance and agonistic interactions that occur to establish and maintain these relationships might express themselves differently…
