Marine Ecology Progress Series (2010)
We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…

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…
Diversity and summer distribution of cetaceans in inlet waters of northern Aisén, Chile
Zamorano-Abramson, José; Gibbons, Jorge; Capella, Juan
Anales del Instituto de la Patagonia (2010)
(...) In this paper we present results on diversity, local distribution and group composition of cetacean species along inshore waters of the fjord Puyuhuapi and Channels Jacaf and Moraleda (between…
Molecular identification of small cetacean samples from Peruvian fish markets
Tzika, Athanasia C.; D’Amico, Eva; Alfaro-Shigueto, Joanna; Mangel, Jeffrey C.; Van Waerebeek, Koen; Milinkovitch, Michel C.
Conservation Genetics (2010)
In the last 60 years, incidental entanglement in fishing gears (so called by-catch) became the main cause of mortality worldwide for small cetaceans and is pushing several populations and species…
