Ecological Indicators (2017)
Concentrations of thirty two polychlorinated biphenyls (PCBs) were determined in the blubber of five sympatric species of odontocetes stranded or by-caught along the Northwest coast of the Iberian Peninsula: common…
Characterization of milk composition in narrow-ridged finless porpoises (Neophocaena asiaeorientalis) at different lactation stages
Zeng, Xianyuan; Huang, Shiang-lin; Qian, Zhengyi; Hao, Yujiang; Wang, Ding; Ji, Junhua; Nabi, Ghulam
Marine Mammal Science (2017)
Lactation plays a vital role in reproductive success, evolving with ecological adaptations of mammalian life histories. Knowledge of the lactation process in odontocetes is scarce and limited to a handful…
Comparison of dolphins’ body and brain measurements with four other groups of cetaceans reveals great diversity
Ridgway, Sam H.; Carlin, Kevin P.; Van Alstyne, Kaitlin R.; Hanson, Alicia C.; Tarpley, Raymond J.
Brain, Behavior and Evolution (2016)
We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…
Harbor porpoise, Phocoena phocoena, abundance estimation for California, Oregon, and Washington: II. Aerial surveys
Barlow, Jay; Oliver, Charles W.; Jackson, Terry D.; Taylor, Barbara L.
Fishery Bulletin (1988)
We conducted aerial surveys in September 1984 and September and October 1985 to determine the abundance of harbor porpoise along the coasts of California, Oregon, and Washington. Two observers and…
Precocious hearing in harbour porpoise neonates
Wahlberg, Magnus; Delgado-García, Lara; Kristensen, Jakob H.
Journal of Comparative Physiology A (2017)
Hearing is the primary sensory modality for toothed whales, but it is not known at which age it is fully developed. For newborn calves, hearing could fill an important function…
Persistent organic pollutants and methoxylated PBDEs in harbour porpoises from the North Sea from 1990 until 2008: Young wildlife at risk?
Weijs, Liesbeth; van Elk, Cornelis; Das, Krishna; Blust, Ronny; Covaci, Adrian
Science of The Total Environment (2010)
In the European North Sea, harbour porpoises are top predators with relatively long life spans and a limited capacity for metabolic biotransformation of contaminants compared to some other marine mammal…
A preliminary study on the variability of the mitochondrial DNA control region in populations of finless porpoises (Neophocaena phocaenoides) in Chinese waters
Yang, Guang; Zhou, Kaiya
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
The mitochondrial DNA control region of 12 finless porpoises (Neophocaena phocaenoides) from the Yangtze River, Yellow Sea, and South China Sea, was amplified. Two portions, 317 and 245 base pairs,…
Studies on echolocation of porpoises taken in salmon gillnet fisheries
Hatakeyama, Yoshimi; Soeda, Hideo
Sensory Abilities of Cetaceans (1990)
(...)In the Bering Sea, marine mammals, particularly Dall's porpoises, Phocoenoides dalli, get incidentally entangled in gillnets of the Japanese mothership salmon fishery. The maximum total number of Dall's porpoises to…
Anatomical and histological characteristics of the eyes of a month-old and an adult harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Zweypfenning, Ruud C. V. J.; Spekreijse, Henk
Sensory Abilities of Cetaceans (1990)
Several anatomical characteristics of the cornea, lens, iris and retina of the eyes of a month-old and an adult harbor porpoise (Phocoena phocoena) were investigated by scanning, transmission and light…
Asymmetry of the nasofacial skull in toothed whales (Odontoceti)
Huggenberger, S.; Leidenberger, S.; Oelschläger, H. H. A.
Journal of Zoology (2016)
In this study, the nasal asymmetry of odontocetes (toothed whales) was analyzed morphometrically by placing landmarks on photographed nasofacial skulls from 12 different species and genera that belong to four…
