Marine Pollution Bulletin (1997)

A wide range of organochlorine residues were determined in the blubber of harbour porpoises from the Black Sea. Concentrations of DDTs (8.3–180 μg g−1 wet weight) were the highest followed…


Diurnal variation in harbour porpoise detection – Potential implications for management

Williamson, L. D.; Brookes, K. L.; Scott, B. E.; Graham, I. M.; Thompson, P. M.
Marine Ecology Progress Series (2017)

Robust information on animal distributions and foraging behaviour is required to target management and conservation measures for protected species and populations. Visual survey data are commonly used to model these…


Habitat-based density models for three cetacean species off southern California illustrate pronounced seasonal differences

Becker, Elizabeth A.; Forney, Karin A.; Thayre, Bruce J.; Debich, Amanda J.; Campbell, Gregory S.; Whitaker, Katherine; Douglas, Annie B.; Gilles, Anita; Hoopes, Ryan; Hildebrand, John A.
Frontiers in Marine Science (2017)

Managing marine species effectively requires spatially and temporally explicit knowledge of their density and distribution. Habitat-based density models, a type of species distribution model (SDM) that uses habitat covariates to…


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…


Diet composition and food consumption rate of harbor porpoises (Phocoena phocoena) in the western Baltic Sea

Andreasen, Heidi; Ross, Stine D.; Siebert, Ursula; Andersen, Niels G.; Ronnenberg, Katrin; Gilles, Anita
Marine Mammal Science (2017)

Stomach content composition and prey-specific consumption rates of juvenile and adult harbor porpoises (Phocoena phocoena) were estimated from a data set including 339 stomachs collected over a 32 yr period…

The monitoring program on harbour porpoises at Horns Rev Offshore Wind Farm in the Danish North Sea, initiated in 1999, has now come to an end with collection of final…


Population- and growth-related differences in helminthic fauna of finless porpoises (Neophocaena asiaeorientalis) in five Japanese populations

Shiozaki, Akira; Amano, Masao
Journal of Veterinary Medical Science (2017)

A survey of helminths and ectoparasites, including epizoits, was conducted in narrow-ridged finless porpoises (Neophocaena asiaeorientalis) from Japanese five populations using dead stranded or incidentally caught animals. In total, 13…
