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…
Differential population dynamics of a coastal porpoise correspond to the fishing effort in a large estuarine system
Lin, Wenzhi; Karczmarski, Leszek; Li, Jun; Chan, Stephen C. Y.; Guo, Lang; Wu, Yuping
Aquatic Conservation: Marine and Freshwater Ecosystems (2019)
The finless porpoise (genus Neophocaena) is susceptible to fishery‐caused mortality, and its numbers are thought to be in decline across its entire range. However, population demographics have rarely been quantified…
Gastric Braunina cordiformis and a review of helminth parasitism in the finless porpoise (Neophocaena phocaenoides)
Lombardini, Eric; Haetrakul, Thanida; Kuit, Sui; Chansue, Nantarika
Brazilian Journal of Veterinary Pathology (2019)
A pregnant adult female finless porpoise (Neophocaena phocaenoides) stranded off the coast of Phuket, Thailand and died during attempted rehabilitation. The cadaver was frozen for use in a Marine mammal…
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…
Porpoises the world over: Diversity in behavior and ecology
Teilmann, Jonas; Sveegaard, Signe
Ethology and Behavioral Ecology of Odontocetes (2019)
Unlike the large number of species of true dolphins, there are only seven porpoise or phocoenid species, inhabiting different habitats and climate zones. They range from ice-covered water in the…
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…
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…
Occurrence of threatened cetacean species and its conservation strategy along Ganjam coast, Odisha
Behera, S. K.; Mohanta, R.; Mishra, S. S.
International Journal of Zoology Studies (2018)
Cetaceans are an important component of marine biodiversity, as apex predators, cetacean abundance and distribution are key indicators of environmental status, such as food web integrity. Five species of cetacean…
Distribution of three sympatric cetacean species off the coast of the central-western Gulf of Thailand
Jutapruet, Suwat; Intongcome, Atichat; Wang, Xianyan; Kittiwattanawong, Kongkiat; Huang, Shiang-Lin
Aquatic Mammals (2017)
Baseline data on the distribution patterns of animals disclose the dynamic function of habitat use as it relates to the accessibility of prey, social interactions, predator-prey interactions, and inter-habitat-patch mobility.…
Assessment of beach-cast cetaceans in Pakistan: Implications for conservation and management
Gore, M. A.; Culloch, R. M.; Gray, H. W. I.; Hoelzel, R.; Lockyer, C.; Kiani, M. S.; Waqas, U.; Hussain, B.; Rahim, A.; Shah, A.; Ormond, R. F. G.
Journal of Cetacean Research and Management (2017)
Until recently, little was known about the distribution and species occurrence of marine cetaceans in Pakistani waters, an area which needed to be addressed exigently given its inclusion in the…
