Lutra (2018)
It is a tradition that regular overviews are published of strandings of cetaceans. The last overviews for Belgium covered the period 1975 to 1989 and 1990 to 1994. This overview…
Acoustic monitoring reveals the times and tides of harbor porpoise (Phocoena phocoena) distribution off central Oregon, U.S.A.
Holdman, Amanda K.; Haxel, Joseph H.; Klinck, Holger; Torres, Leigh G.
Marine Mammal Science (2018)
Harbor porpoises (Phocoena phocoena) are commonly observed in Oregon's nearshore marine environment yet knowledge of their ecosystem use and behavior remains limited, generating concerns for potential impacts on this species…
Water, water everywhere: Environmental DNA can unlock population structure in elusive marine species
Parsons, Kim M.; Everett, Meredith; Dahlheim, Marilyn; Park, Linda
Royal Society Open Science (2018)
Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a…
Cetacean stranding records along the Danish coastline: Records for the period 2008-2017 and a comparative review
Kinze, C. C.; Thøstesen, C. B.; Olsen, M. T.
Lutra (2018)
For the period 2008-2017, finds of stranded cetaceans along the Danish coastline are listed and reviewed in comparison to the preceding 40-year period (1968-2007). The harbour porpoise (Phocoena phocoena) was…
Seasonal changes in food consumption, respiration rate, and body condition of a male harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Helder-Hoek, Lean; Jennings, Nancy
Aquatic Mammals (2018)
Seasonal changes in food consumption, respiration rate, and body condition in a healthy captive male harbor porpoise (Phocoena phocoena) from the North Sea were recorded over 8 y. He was…
Environmental drivers of harbour porpoise fine-scale movements
van Beest, Floris M.; Teilmann, Jonas; Dietz, Rune; Galatius, Anders; Mikkelsen, Lonnie; Stalder, Dominique; Sveegaard, Signe; Nabe-Nielsen, Jacob
Marine Biology (2018)
Quantifying intraspecific variation in movement behaviour of marine predators and the underlying environmental drivers is important to inform conservation management of protected species. Here, we provide the first empirical data…
Feeding behaviour of harbour porpoises (Phocoena phocoena) in the Ems estuary
Weel, S. M. H.; Geelhoed, S. C. V.; Tulp, I.; Scheidat, M.
Lutra (2018)
Passive acoustic monitoring (PAM) was used to study the occurrence and distribution of feeding behaviour of harbour porpoises (Phocoena phocoena) in the Ems estuary, on the border between the Netherlands…
Spatial avoidance to experimental increase of intermittent and continuous sound in two captive harbour porpoises
Kok, Annebelle C. M.; Engelberts, J. Pamela; Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; Visser, Fleur; Slabbekoorn, Hans
Environmental Pollution (2018)
The continuing rise in underwater sound levels in the oceans leads to disturbance of marine life. It is thought that one of the main impacts of sound exposure is the…
Does interspecific competition drive patterns of habitat use and relative density in harbour porpoises?
Díaz López, Bruno; Methion, Séverine
Marine Biology (2018)
Determining the drivers that are responsible for the fine-scale distribution of cetacean species is fundamental to understand better how they respond to changes in their environment. We utilized information theoretic…
Behavioral responses of harbor porpoises (Phocoena phocoena) to sonar playback sequences of sweeps and tones (3.5-4.1 kHz)
Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; de Winter, Simone; Janssen, Susan; Ainslie, Michael A.
Aquatic Mammals (2018)
Naval sonar signals may affect the behavior of harbor porpoises (Phocoena phocoena). The 53C sonar system produces 1,600 ms sonar signals in the 3.5 to 4.1 kHz band, each consisting…
