Increasing anthropogenic activities in the marine environment are potential threats to the health of harbor porpoises by causing unnatural continuous stress to the animals. The present study was a first…
Tissue healing in two harbor porpoises (Phocoena phocoena) following long-term satellite transmitter attachment
Sonne, Christian; Teilmann, Jonas; Wright, Andrew J.; Dietz, Rune; Leifsson, Pall S.
Marine Mammal Science (2011)
(...) The present note evaluates, through postmortem findings, the effect of the attachment of satellite transmitters to the dorsal fin of two wild porpoises that were later lethally bycaught in…

First records of anomalously white harbor porpoises (Phocoena phocoena) from the Pacific ocean
Keener, William; Szczepaniak, Isidore; Ü, Adam; Webber, Marc; Stern, Jonathan
Journal of Marine Animals and Their Ecology (2011)
Anomalously white cetaceans are rarely seen, and only five records of white harbor porpoises (Phocoena phocoena) are found in the literature. We provide an updated list of those records, and…
“Porpicide” in California: Killing of harbor porpoises (Phocoena phocoena) by coastal bottlenose dolphins (Tursiops truncatus)
Cotter, Mark P.; Maldini, Daniela; Jefferson, Thomas A.
Marine Mammal Science (2011)
Between 2007 and 2009, we witnessed three aggressive interactions between harbor porpoises and bottlenose dolphins in Monterey Bay, California. This is the first time such aggression has been documented in…
Harbor porpoise observations in Burrows Pass, December 2009 through December 2010
Jeffries, A.
(2011)
Pacific Biodiversity Institute (PBI) initiated a study of the harbor porpoise in the Puget Sound in 2007. One of the early outcomes of this study was to identify an area,…
High-density areas for harbor porpoises (Phocoena phocoena) identified by satellite tracking
Sveegaard, Signe; Teilmann, Jonas; Tougaard, Jakob; Dietz, Rune; Mouritsen, Kim N.; Desportes, Geneviève; Siebert, Ursula
Marine Mammal Science (2010)
The population status of harbor porpoises has been of concern for several years, and the establishment of Marine Protected Areas (MPAs) has been suggested as a method to protect the…
Protected species bycatch estimating approaches: Estimating harbor porpoise bycatch in U.S. Northwestern Atlantic gillnet fisheries
Orphanides, C. D.
Journal of Northwest Atlantic Fishery Science (2010)
Harbor porpoise bycatch estimates for federally managed gillnet fisheries in northwestern Atlantic US waters were calculated for a nine-year period (1999–2007) using two new methods, and the results were compared…
Genetic and historic evidence for climate-driven population fragmentation in a top cetacean predator: The harbour porpoises in European water
Fontaine, Michaël C.; Tolley, Krystal A.; Michaux, Johan R.; Birkun, Alexei; Ferreira, Marisa; Jauniaux, Thierry; Llavona, Ángela; Öztürk, Bayram; Öztürk, Ayaka A; Ridoux, Vincent; Rogan, Emer; Sequeira, Marina; Bouquegneau, Jean-Marie; Baird, Stuart J. E.
Proceedings of the Royal Society B: Biological Sciences (2010)
Recent climate change has triggered profound reorganization in northeast Atlantic ecosystems, with substantial impact on the distribution of marine assemblages from plankton to fishes. However, assessing the repercussions on apex…
Prey capture by harbor porpoises (Phocoena phocoena): A comparison between echolocators in the field and in captivity
Miller, L.A.
The Journal of the Marine Acoustics Society of Japan (2010)
The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…
