PLOS ONE (2023)
Small odontocetes produce echolocation clicks to feed and navigate, making it an essential function for their survival. Recently, the effect of vessel noise on small odontocetes behavior has attracted attention…
A drone study of sociality in the finless porpoise Neophocaena asiaeorientalis in the Ariake Sound, Japan
Morimura, Naruki; Itahara, Akihiro; Brooks, James; Mori, Yusuke; Piao, Yige; Hashimoto, Hiroki; Mizumoto, Itsuki
Drones (2023)
The social structure of animal populations is a fundamental component of their biology, influencing gene flow, habitat use, competition and co-operation around resources, and communication. However, ecological and social relationships…
Out of sight, out of mind: How conservation is failing European porpoises
Carlén, Ida; Nunny, Laetitia; Simmonds, Mark P.
Frontiers in Marine Science (2021)
The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well…
The click production of captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaorientalis) is influenced by social and environmental factors
Serres, Agathe; Xu, Chen; Hao, Yujiang; Wang, Ding
Animals (2021)
Yangtze finless porpoises use high-frequency clicks to navigate, forage, and communicate. The way in which click production may vary depending on social or environmental context has never been investigated. A…
Contextual impacts on individual and synchronous breathing rate variations in three captive odontocete groups
Serres, Agathe; Hao, Yujiang; Wang, Ding
Zoo Biology (2020)
Breathing rates are often collected both in the wild and in captivity to inform on cetaceans' internal state. However, few studies have investigated the effect of various factors on this…
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…
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…
The bacterial diversity in infected tissue pus of an East Asian finless porpoise
Wu, Caiwen; Hong, Zhe; Ibrahim, Aamir; Zhang, Di; Wang, Lin; Li, Ting; Chen, Bingyao
African Journal of Microbiology Research (2019)
Two East Asian finless porpoises (Neophocaena asiaeorientalis sunameri) in Ningbo, East China Sea, China, were observed to be bacterially infected between the fat layer and muscle layer. The microbial communities…
Genetic footprint of population fragmentation and contemporary collapse in a freshwater cetacean
Chen, Minmin; Fontaine, Michael C.; Ben Chehida, Yacine; Zheng, Jinsong; Labbé, Frédéric; Mei, Zhigang; Hao, Yujiang; Wang, Kexiong; Wu, Min; Zhao, Qingzhong; Wang, Ding
Scientific Reports (2017)
Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of…
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…
