Prey capture by harbor porpoises (Phocoena phocoena): A comparison between echolocators in the field and in captivity
Miller, L.A.
The Journal of the Marine Acoustics Society of Japan (2010)
The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…
Small cetacean captures in Peruvian artisanal fisheries: High despite protective legislation
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Van Waerebeek, Koen; Cáceres, Celia; Bearhop, Stuart; Witt, Matthew J.; Godley, Brendan J.
Biological Conservation (2010)
We detail the first direct, at sea monitoring of small cetacean interactions with Peruvian artisanal drift gillnet and longline fisheries. A total of 253 small cetaceans were captured during 66…
Microsatellite variation and significant population genetic structure of endangered finless porpoises (Neophocaena phocaenoides) in Chinese coastal waters and the Yangtze River
Chen, Lian; Bruford, Michael W.; Xu, Shixia; Zhou, Kaiya; Yang, Guang
Marine Biology (2010)
The finless porpoise (Neophocaena phocaenoides) inhabits a wide range of tropical and temperate waters of the Indo-Pacific region. Genetic structure of finless porpoises in Chinese waters in three regions (Yangtze…
Abundance of harbor porpoise (Phocoena phocoena) in three Alaskan regions, corrected for observer errors due to perception bias and species misidentification, and corrected for animals submerged from view
Hobbs, Roderick C.; Waite, Janice M.
Fishery Bulletin (2010)
Estimating the abundance of cetaceans from aerial survey data requires careful attention to survey design and analysis. Once an aerial observer perceives a marine mammal or group of marine mammals,…
High-density areas for harbor porpoises (Phocoena phocoena) identified by satellite tracking
Sveegaard, Signe; Teilmann, Jonas; Tougaard, Jakob; Dietz, Rune; Mouritsen, Kim N.; Desportes, Geneviève; Siebert, Ursula
Marine Mammal Science (2010)
The population status of harbor porpoises has been of concern for several years, and the establishment of Marine Protected Areas (MPAs) has been suggested as a method to protect the…
Variation in sexual behaviors in a group of captive male Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis): Motivated by physiological changes?
Wu, Hai-Ping; Hao, Yu-Jiang; Yu, Xue-Ying; Xian, Yi-Jie; Zhao, Qing-Zhong; Chen, Dao-Quan; Kuang, Xin-An; Kou, Zhang-Bin; Feng, Kang-Kang; Gong, Wei-Ming; Wang, Ding
Theriogenology (2010)
Most male mammals in temperate regions demonstrate seasonal sexual behaviors that coincide with seasonal variations in gonadal activities and androgen hormones. The Yangtze finless porpoise is a temperate freshwater cetacean…
Population status, threats and conservation of the Yangtze finless porpoise
Wang, Ding
Chinese Science Bulletin (2009)
The Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) is currently limited to the middle and lower reaches of the Yangtze River from Yichang to Shanghai, China, and the adjoining Poyang and…
Paedomorphic ossification in porpoises with an emphasis on the Vaquita (Phocoena sinus)
Mellor, Liliana; Cooper, Lisa Noelle; Torre, Jorge; Brownell, Robert L.
Aquatic Mammals (2009)
Heterochrony, the change in timing of developmental processes, is thought to be a key process shaping the numerous limb morphologies of tetrapods. Through a delayed offset in digit development, all…
Epidemiological pattern of tattoo skin disease: A potential general health indicator for cetaceans
Van Bressem, M. F.; Van Waerebeek, K.; Aznar, F. J.; Raga, J. A.; Jepson, P. D.; Duignan, P.; Deaville, R.; Flach, L.; Viddi, F.; Baker, J. R.; Di Beneditto, A. P.; Echegaray, M.; Genov, T.; Reyes, J.; Felix, F.; Gaspar, R.; Ramos, R.; Peddemors, V.; Sanino, G. P.; Siebert, U.
Diseases of Aquatic Organisms (2009)
The presence of tattoo skin disease (TSD) was examined in 1392 free-ranging and dead odontocetes comprising 17 species from the Americas, Europe, South Africa, New Zealand and Greenland. We investigated…
