Epiphyseal development was investigated on X-rays of flippers from 158 harbour porpoises from Danish waters. Development followed a proximodistal pattern similar to what is known in other cetacean species. Ossification…

Mammalian body condition is an important individual fitness metric as it affects both survival and reproductive success. The ability to accurately measure condition has key implications for predicting individual and…


Dentinal anomalies in teeth of harbour porpoises (Phocoena phocoena) from Scottish waters: Are they linked to sexual maturation and environmental events?

Luque, P. L.; Pierce, G. J.; Learmonth, J. A.; Santos, M. B.; Ieno, E.; López, A.; Reid, R. J.; Rogan, E.; González, A. F.; Boon, J.; Law, R. J.; Lockyer, C. H.
Journal of the Marine Biological Association of the United Kingdom (2009)

We examined the tooth ultra-structure of harbour porpoises (Phocoena phocoena) from Scottish waters to determine whether the incidence of mineralization anomalies could be related to certain life history events (e.g.…


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…


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…
