Canadian Journal of Zoology (2011)
All extant porpoise species show paedomorphic skeletal traits. These traits are hypothesized to be connected with rapid growth to reproductive size and could thus show geographic variation according to ecological…
Timing of epiphyseal development in the flipper skeleton of the harbour porpoise (Phocoena phocoena) as an indicator of paedomorphosis
Galatius, Anders; Andersen, Mai-Britt Elin Rindom; Haugan, Birgitte; Langhoff, Heidi Elisabeth; Jespersen, Åse
Acta Zoologica (2006)
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…
Where is the risk? Integrating a spatial distribution model and a risk assessment to identify areas of cetacean interaction with fisheries in the northeast Atlantic
Breen, Patricia; Brown, Susie; Reid, David; Rogan, Emer
Ocean & Coastal Management (2017)
Throughout their range, marine mammals are vulnerable to incidental capture in fishing gear. Bycatch is a particularly important issue for cetaceans, which generally have lower potential rates of population growth…
Evaluating morphometric and metabolic markers of body condition in a small cetacean, the harbor porpoise (Phocoena phocoena)
Kershaw, Joanna L.; Sherrill, Meredith; Davison, Nicholas J.; Brownlow, Andrew; Hall, Ailsa J.
Ecology and Evolution (2017)
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…
Harbour porpoise (Phocoena phocoena) static acoustic monitoring: Laboratory detection thresholds of T-PODs are reflected in field sensitivity
Kyhn, Line A.; Tougaard, Jakob; Teilmann, Jonas; Wahlberg, Magnus; Jørgensen, Poul B.; Bech, Nikolaj I.
Journal of the Marine Biological Association of the United Kingdom (2008)
The T-POD (Timing POrpoise Detector) is a self-contained acoustic data logger used for detecting and monitoring the presence of echolocation clicks of small cetaceans. It has become a standard tool…
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…
Causes of mortality of harbor porpoises Phocoena phocoena along the Atlantic and Pacific coasts of Canada
Fenton, H.; Daoust, P. Y.; Forzán, M. J.; Vanderstichel, R. V.; Ford, J. K. B.; Spaven, L.; Lair, S.; Raverty, S.
Diseases of Aquatic Organisms (2017)
There is increasing public interest in the overall health of the marine environment. Harbor porpoises Phocoena phocoena have a coastal distribution, and stranded animals function as sentinels for population and…
Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area
Wingfield, Jessica E.; O’Brien, Michael; Lyubchich, Vyacheslav; Roberts, Jason J.; Halpin, Patrick N.; Rice, Aaron N.; Bailey, Helen
PLOS ONE (2017)
Offshore windfarms provide renewable energy, but activities during the construction phase can affect marine mammals. To understand how the construction of an offshore windfarm in the Maryland Wind Energy Area…
Persistent organic pollutant and hormone levels in harbor porpoise with B cell lymphoma
Norman, Stephanie A.; Winfield, Zach C.; Rickman, Barry H.; Usenko, Sascha; Klope, Matthew; Berta, Susan; Dubpernell, Sandra; Garrett, Howard; Adams, Mary Jo; Lambourn, Dyanna; Huggins, Jessica L.; Lysiak, Nadine; Clark, Adelaide E.; Sanders, Rebel; Trumble, Stephen J.
Archives of Environmental Contamination and Toxicology (2017)
B-cell lymphoma, a common morphologic variant of non-Hodgkin lymphoma, has been associated with persistent pollutants in humans, but this association is not well-characterized in top-level predators sharing marine resources with…
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.…
