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,…
Tissue-specific accumulation and body burden of parabens and their metabolites in small cetaceans
Jeong, Yunsun; Xue, Jingchuan; Park, Kyum Joon; Kannan, Kurunthachalam; Moon, Hyo-Bang
Environmental Science & Technology (2018)
Parabens have been of global concern due to their endocrine disrupting properties. However, few studies have reported tissue-specific distribution of parabens in wildlife. In this study, we measured parabens and…
Raising your voice: Evolution of narrow-band high-frequency signals in toothed whales (Odontoceti)
Galatius, Anders; Olsen, Morten Tange; Steeman, Mette Elstrup; Racicot, Rachel A.; Bradshaw, Catherine D; Kyhn, Line A.; Miller, Lee A.
Biological Journal of the Linnean Society (2018)
Cetaceans use sound for communication, navigation and finding prey. Most extant odontocetes produce broadband (BB) biosonar clicks covering frequency ranges from tens of kilohertz to 150–170 kHz. In contrast, the…
Characterization of milk protein composition of the Yangtze finless porpoise
Zeng, Xianyuan; Chen, Minmin; Liu, Zhigang; Yu, Daoping; Huang, Shiang-Lin; Yang, Jiwei; Fan, Fei; Wang, Ding; Hao, Yujiang; Nabi, Ghulam
Marine Mammal Science (2018)
...Milk protein composition likely varies between lactation stages in the finless porpoise (Zeng et al. 2017). Zeng et al. (2017) indicate that crude protein concentration is much higher in colostrum…
Morphological analysis of the foramen magnum in finless porpoise (genus Neophocaena) using postmortem computed tomography 3D volume rendered images
Kot, Brian Chin Wing; Chan, Derek Kam Ping; Yuen, Adams Hei Long; Wong, Francis Ho Man; Tsui, Henry Chun Lok
Marine Mammal Science (2018)
...In the course of the pioneer virtopsy-driven stranding response program in Hong Kong (HK) waters, virtopsy using postmortem computed tomography (PMCT) has been implemented to augment conventional necropsy. A growing…
