Mammalian adipose tissue is increasingly being recognized as an endocrine organ involved in the regulation of a number of metabolic processes and pathways. It responds to signals from different hormone…
Plastic ingestion by harbour porpoises Phocoena phocoena in the Netherlands: Establishing a standardised method
van Franeker, Jan A.; Bravo Rebolledo, Elisa L.; Hesse, Eileen; IJsseldijk, Lonneke L.; Kühn, Susanne; Leopold, Mardik; Mielke, Lara
Ambio (2018)
Stomach contents of harbour porpoises (Phocoena phocoena) collected in the Netherlands between 2003 and 2013 were inspected for the presence of plastic and other man-made litter. In 654 stomach samples…
Estimating effective detection area of static passive acoustic data loggers from playback experiments with cetacean vocalisations
Nuuttila, Hanna K.; Brundiers, Katharina; Dähne, Michael; Koblitz, Jens C.; Thomas, Len; Courtene‐Jones, Winnie; Evans, Peter G. H.; Turner, John R.; Bennell, Jim D.; Hiddink, Jan G.
Methods in Ecology and Evolution (2018)
Passive acoustic monitoring (PAM) is used for many vocal species. However, few studies have quantified the fraction of vocalisations captured, and how animal distance and sound source level affect detection…
Abundance of harbour porpoises (Phocoena phocoena) on the Dutch continental shelf, aerial surveys 2012-2017
Geelhoed, S. C. V.; Scheidat, M.
Lutra (2018)
The harbour porpoise (Phocoena phocoena) is the most abundant marine mammal species in Dutch waters. Aerial surveys along predesigned track lines in 2012-2017 provided density and abundance estimates for the…
The metabolic cost of swimming and reproduction in harbor porpoises (Phocoena phocoena) as predicted by a bioenergetic model
Gallagher, Cara A.; Stern, S. Jonathan; Hines, Ellen
Marine Mammal Science (2018)
While harbor porpoises currently enter San Francisco Bay year‐round, evidence suggests a disappearance that spanned approximately 65 yr. The range of energetic costs of basal metabolism, locomotion, thermoregulation, and reproduction…
Click reception in the harbor porpoise (Phocoena phocoena): Effects of electrode and contact transducer location on the auditory brainstem response
Mulsow, Jason; Finneran, James J.; Houser, Dorian S.; Nordstrom, Chad A.; Barrett-Lennard, Lance G.; Burkard, Robert F.
The Journal of the Acoustical Society of America (2018)
Unlike terrestrial mammals that have unambiguous aerial sound transmission pathways via the outer ear and tympanum, sound reception pathways in most odontocetes are not well understood. Recent studies have used…
About stranding and accidentally caught cetaceans in the Black Sea: Death reasons, feeding characteristics and pregnancy status
Bilgin, Sabri; Onay, Hatice; Köse, Ozay; Yeşilçiçek, Tuncay
Türk Tarım ve Doğa Bilimleri Dergisi (2018)
This study was carried out to determine stranding levels, dead reasons and some reproduction features and diet of the Black Sea’ cetacean species (harbour porpoise, Phocoena phocoena and common dolphin,…
Strandings of cetaceans in Belgium from 1995 to 2017
Haelters, J.; Kerckhof, F.; Jauniaux, T.
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…
