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…


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…


Odontocetes of the Southern Ocean Sanctuary

Van Waerebeek, K.; Leaper, R.; Baker, A. N.; Papastavrou, V.; Thiele, D.; Findlay, K.; Donovan, G.; Ensor, P.
Journal of Cetacean Research and Management (2010)

Twenty-eight odontocete species were identified as occupying sub-Antarctic and Antarctic habitat covered by the 1994 IWC-established Southern Ocean Sanctuary. Toothed whales evidently play an important part in the Antarctic polar…


B-Mode ultrasonographic evaluation of the testis in relation to serum testosterone concentration in male Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) during the breeding season

Wu, H.-P.; Hao, Y.-J.; Li, X.; Zhao, Q.-Z.; Chen, D.-Q.; Kuang, X.-A.; Kou, Z.-B.; Feng, K.-K.; Gong, W.-M.; Wang, D.
Theriogenology (2010)

The use of ultrasonography as a noninvasive tool for assessing the reproductive status of the male Yangtze finless porpoise (YFP; Neophocaena phocaenoides asiaeorientalis) was validated by correlating ultrasonographically determined testicular…


Isotopic assessment of prey and habitat preferences of a cetacean community in the southwestern South Atlantic Ocean

Riccialdelli, L.; Newsome, S. D.; Fogel, M. L.; Goodall, R. N. P.
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…


Changes in click source levels with distance to targets: Studies of free-ranging white-beaked dolphins Lagenorhynchus albirostris and captive harbour porpoises Phocoena phocoena

Atem, Ana Carolina G.; Rasmussen, Marianne H.; Wahlberg, Magnus; Petersen, Hans C.; Miller, Lee A.;
Bioacoustics (2009)

Probably all odontocetes use echolocation for spatial orientation and detection of prey. We used a four hydrophone “Y” array to record the high frequency clicks from free-ranging White-beaked Dolphins Lagenorhynchus…
