Environmental Pollution (2020)
Underwater sound plays an important role in some critical life functions of many aquatic animals. Underwater noise pollution has received relatively more attention in ocean systems. However, little attention has…
Habitat succession of the Yangtze finless porpoise in Poyang Lake under the changing hydrodynamic and feeding environment
Han, Yong; Sun, Zhiyu; Fang, Hongwei; Bai, Sen; Huang, Lei; He, Guojian
Ecological Modelling (2020)
Poyang Lake, located in the middle and lower reaches of the Yangtze River, is the largest freshwater lake in China and the most important habitat for the Yangtze finless porpoise.…
Swimming features in captive odontocetes: Indicative of animals’ emotional state?
Serres, Agathe; Hao, Yujiang; Wang, Ding
Behavioural Processes (2020)
Captive welfare studies in odontocete species have been mostly conducted on bottlenose dolphins (Tursiops truncatus) while the welfare of many other species’ -including endangered species- remains poorly studied. More research…
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…
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…
Histological variation in blubber morphology of the endangered East Asian finless porpoise (Neophocaena asiaeorientalis sunameri) with ontogeny and reproductive states
Ji, Junhua; Nabi, Ghulam; Zeng, Xianyuan; Hao, Yujiang; Wang, Ding
Zoological Studies (2019)
The highly lipid-rich blubber in the hypodermis is a specialized structure that functions in thermoregulation, energy storage, buoyancy control, locomotion, and streamlining the body shape in marine mammals. The key…
Position at birth and possible effects on calf survival in finless porpoises (Neophocaena asiaeorientalis)
Deng, Xiaojun; Hao, Yujiang; Serres, Agathe; Wang, Kexiong; Wang, Ding
Aquatic Mammals (2019)
Odontocetes are usually reported giving birth to calves in breech position (fluke-first). Cephalic position (head-first) is less frequently observed and, therefore, is considered to be abnormal for the parturition. However,…
Abundance decline in the narrow‐ridged finless porpoise population off the Pacific coast of eastern Japan
Shirakihara, Kunio; Nakahara, Fumio; Shinohara, Masanori; Shirakihara, Miki; Hiramatsu, Kazuhiko; Irie, Takahiro
Population Ecology (2019)
The narrow‐ridged finless porpoise Neophocaena asiaeorientalis is a small‐toothed whale with a coastal habitat and is sensitive to human activity. Aerial sighting surveys were conducted in 2012 to evaluate the…
