Evolution (2017)
Male genital diversification is likely the result of sexual selection. Female genital diversification may also result from sexual selection, although it is less well studied and understood. Female genitalia are…
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…
High field metabolic rates of wild harbour porpoises
Rojano-Doñate, Laia; McDonald, Birgitte I.; Wisniewska, Danuta M.; Johnson, Mark; Teilmann, Jonas; Wahlberg, Magnus; Højer-Kristensen, Jakob; Madsen, Peter T.
The Journal of Experimental Biology (2018)
Reliable estimates of field metabolic rates (FMRs) in wild animals are essential for quantifying their ecological roles, as well as for evaluating fitness consequences of anthropogenic disturbances. Yet, standard methods…
Tissue-specific accumulation and body burden of parabens and their metabolites in small cetaceans
Jeong, Yunsun; Xue, Jingchuan; Park, Kyum Joon; Kannan, Kurunthachalam; Moon, Hyo-Bang
Environmental Science & Technology (2018)
Parabens have been of global concern due to their endocrine disrupting properties. However, few studies have reported tissue-specific distribution of parabens in wildlife. In this study, we measured parabens and…
Loop-mediated isothermal amplification (LAMP) as a confirmatory and rapid DNA detection method for grey seal (Halichoerus grypus) predation on harbour porpoises (Phocoena phocoena)
Heers, Teresa; van Neer, Abbo; Becker, André; Gross, Stephanie; Hansen, Kirstin Anderson; Siebert, Ursula; Abdulmawjood, Amir
Journal of Sea Research (2018)
An increasing number of harbour porpoises along the coastlines of northern Europe are victims of attacks by preying grey seals. To confirm grey seal attacks at a molecular level, a…
Not just fat: Investigating the proteome of cetacean blubber tissue
Kershaw, Joanna L.; Botting, Catherine H.; Brownlow, Andrew; Hall, Ailsa J.
Conservation Physiology (2018)
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…
Predicting harbour porpoise (Phocoena phocoena) activity in the Eastern Scheldt
Gansen, C.; Hoeneveld, J.-L.; Poot, J.
(2018)
The harbour porpoise (Phocoena phocoena) is a small ceteacean species and is common in Dutch coastal waters. The Eastern Scheldt, an estuary in the Dutch province of Zeeland, housed a…
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…
Seasonal and diel patterns in cetacean use and foraging at a potential marine renewable energy site
Nuuttila, Hanna K.; Bertelli, Chiara M.; Mendzil, Anouska; Dearle, Nessa
Marine Pollution Bulletin (2018)
Marine renewable energy (MRE) developments often coincide with sites frequented by small cetaceans. To understand habitat use and assess potential impact from development, echolocation clicks were recorded with acoustic click…
Influence of anthropogenic activities on marine mammal strandings in the estuary and northwestern Gulf of St. Lawrence, Quebec, Canada, 1994–2008
Truchon, M.-H.; Measures, L.; Brêthes, J.-C.; Albert, É.; Michaud, R.
Journal of Cetacean Research and Management (2018)
Stranding records have long been used to monitor marine mammal mortalities and to help identify threats to populations. In coastal areas, marine mammals face numerous anthropogenic threats such as marine…
