We studied the growth and reproduction of finless porpoises in southern China, based on 86 specimens collected as strandings or fisheries bycatches in Hong Kong, southern Fujian Province, and Taiwan.…
Harbour porpoises (Phocoena phocoena) in the North Atlantic: Biological parameters
Lockyer, Christina
NAMMCOSP (2003)
Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings. All…
Foraging behaviour and reproductive season habitat selection of northeast Pacific porpoises
Hall, A.
Doctoral Thesis - University of British Columbia (2011)
Behavioural observations are fundamental to understanding and defining the habitat needs of animals. I compiled the behavioural repertoires reported for harbour (Phocoena phocoena) and Dall’s porpoise (Phocoenoides dalli) by classifying…
Life history of the vaquita, Phocoena sinus (Phocoenidae, Cetacea)
Hohn, A. A.; Read, A. J.; Fernandez, S.; Vidal, O.; Findley, L. T.
Journal of Zoology (1996)
The vaquita, Phocoena sinus, is the most endangered marine cetacean primarily due to incidental mortality in fishing nets. We examined a sample of 56 vaquitas to study the life history…
Subcellular distribution of trace elements in kidney of a mother–fetus pair of Dall’s porpoises (Phocoenoides dalli)
Yang, Jian; Kunito, Takashi; Anan, Yasumi; Tanabe, Shinsuke; Miyazaki, Nobuyuki
Chemosphere (2008)
Total and subcellular renal Zn, Cu, Se, Mn, V, Hg, Cd and Ag were determined by a mother–fetus pair of Dall’s porpoises (Phocoenoides dalli). All element concentrations in the maternal…
Natural hybridization between Dall’s porpoises (Phocoenoides dalli) and harbour porpoises (Phocoena phocoena)
Willis, Pamela M; Crespi, Bernard J; Dill, Lawrence M; Baird, Robin W; Hanson, M Bradley
Can. J. Zool. (2004)
Natural hybridization occurs rarely in mammals compared with other taxonomic groups of animals. Cetaceans appear unique among mammals in exhibiting striking karyological uniformity, which suggests that they have the potential…
Mate guarding in male Dall’s porpoises (Phocoenoides dalli)
Willis, Pamela M.; Dill, Lawrence M.
Ethology (2007)
Mate guarding, whereby a male closely attends and defends a fertile female from extra-pair matings, is one mating tactic males of many species use to protect their paternity. Although female…
The natural history of Dall’s Porpoise in the north Pacific Ocean
Morejohn, G. Victor
Behavior of Marine Animals (1979)
Dall’s porpoise, Phocoenoides dalli (True), is commonly encountered over the continental shelf of North America and in offshore and pelagic waters of the western and eastern North Pacific Ocean. This…
Calving seasonality of Dall’s porpoise in the eastern north Pacific
Jefferson, Thomas A.
Marine Mammal Sci (1989)
(...) Four newborn Dall’s porpoises were examined by the author during July of 1987 and 1988. All had muted color patterns, and some evidence of umbilical remnants, fetal folds, and…
Age, growth, and reproductive patterns of Dall’s porpoise (Phocoenoides dalli) in the central north Pacific ocean
Ferrero, Richard C.; Walker, William A.
Marine Mammal Sci (1999)
Life history parameters were estimated for Dall's porpoise, Phocoenoides dalli, from biological specimens collected in the western Aleutian Islands, during 1981–1987. Of 2,033 males and 3,566 females examined, reproductive data…
