Aquatic Mammals (2017)
Harbor porpoises (Phocoena phocoena) were rarely seen in San Francisco Bay prior to 2008 despite numerous marine mammal search efforts beginning in the 1970s. The species inhabited the bay historically…
Linear transect surveys of abundance and density of cetaceans in the area near the Dzharylgach Island in the north-western Black Sea
Gladilina, E. V.; Vishnyakova, K. A.; Neprokin, O. O.; Ivanchikova, Yu. F.; Derkacheva, T. A.; Kryukova, A. A.; Savenko, O. V.; Gol’din, P. E.
Vestnik Zoologii (2017)
The first assessment of cetacean density and abundance by linear transect survey was conducted in 2016 and 2017 in the shallowest coastal area of the Ukrainian sector of the north-western…
Long-term tag retention on two species of small cetaceans
Heide-Jørgensen, Mads Peter; Nielsen, Nynne H.; Teilmann, Jonas; Leifsson, Páll S.
Marine Mammal Science (2017)
The effects of tagging on small cetaceans are difficult to assess due to logistical difficulties in recapturing the whales. In this study two narwhals, Monodon monoceros, and five harbor porpoises,…
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…
Dead useful; methods for quantifying baseline variability in stranding rates to improve the ecological value of the strandings record as a monitoring tool
ten Doeschate, Mariel T. I.; Brownlow, Andrew C.; Davison, Nicholas J.; Thompson, Paul M.
Journal of the Marine Biological Association of the United Kingdom (2017)
The ecological value of the stranding record is often challenged due to the complexity in quantifying the biases associated with multiple components of the stranding process. There are biological, physical…
Long-term association between a solitary common dolphin (Delphinus delphis delphis) and a harbour porpoise (Phocoena phocoena)
Ryan, Conor; Macleod, Greig; Dinsdale, Cameron; Cook, Stuart
Aquatic Mammals (2017)
(...)The occurrence of solitary dolphins (i.e., those in isolation from conspecifics) is well-documented in the case of bottlenose dolphins (Tursiops truncatus) along the western seaboard of northern Europe (Lockyer, 1990);…
Don’t forget the porpoise: Acoustic monitoring reveals fine scale temporal variation between bottlenose dolphin and harbour porpoise in Cardigan Bay SAC
Nuuttila, Hanna K.; Courtene-Jones, Winnie; Baulch, Sarah; Simon, Malene; Evans, Peter G. H.
Marine Biology (2017)
Populations of bottlenose dolphin and harbour porpoise inhabit Cardigan Bay, which was designated a Special Area of Conservation (SAC), with bottlenose dolphin listed as a primary feature for its conservation…
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…
Passive acoustic methods for fine-scale tracking of harbour porpoises in tidal rapids
Macaulay, Jamie; Gordon, Jonathan; Gillespie, Douglas; Malinka, Chloë; Northridge, Simon
The Journal of the Acoustical Society of America (2017)
The growing interest in generating electrical power from tidal currents using tidal turbine generators raises a number of environmental concerns, including the risk that marine mammals might be injured or…
Genital interactions during simulated copulation among marine mammals
Orbach, Dara N.; Kelly, Diane A.; Solano, Mauricio; Brennan, Patricia L. R.
Proceedings of the Royal Society B: Biological Sciences (2017)
Genitalia are morphologically variable across many taxa and in physical contact during intromission, but little is known about how variation in form correlates with function during copulation. Marine mammals offer…
