A risk‐based forecast of extreme mortality events in small cetaceans: Using stranding data to inform conservation practice

Conservation Letters, 2019
Effective conservation requires monitoring and pro‐active risk assessments. We studied the effects of at‐sea mortality events (ASMEs) in marine mammals over two decades (1990–2012) and built a risk‐based indicator for the European Union's Marine Strategy

Central nervous system disease and genital disease in harbor porpoises (Phocoena phocoena) are associated with different herpesviruses [PDF]

, 2016
Herpesvirus infection causes disease of variable severity in many species, including cetaceans. However, little is known about herpesvirus infection in harbor porpoises (Phocoena phocoena), despite being widespread in temperate coastal waters of the ...

Life history and ecology of harbour porpoises (Phocoena phocoena) from West Greenland

NAMMCO Scientific Publications, 2003
During 1988, 1989 and 1995, 187 harbour porpoises (Phocoena phocoena) were sampled from the catches off West Greenland. The samples were taken in 3 areas between 62° N and 70° N: northerly (n=134, Maniitsoq and locations Kangaamiut, Qeqertarsuaq and ...

Combining DNA metabarcoding with macroscopic analysis increases the number of detected prey taxa in the estimated diet for harbour porpoises

Frontiers in Marine Science
Knowledge of animal diets is fundamental in ecology as it can provide insight into the structure, function and resilience of entire ecosystems. In this study we investigate the diet composition of the harbour porpoise (Phocoena phocoena), a small marine ...

Zn, Cu, Cd and Hg binding to metallothioneins in harbour porpoises Phocoena phocoena from the southern North Sea [PDF]

, 2006
Background: Harbour porpoises Phocoena phocoena from the southern North Sea are known to display high levels of Zn and Hg in their tissues linked to their nutritional status (emaciation). The question arises regarding a potential role of metallothioneins

Bruinvisstrandingen in Nederland in 2006: achtergronden, leeftijdsverdeling, sexratio, voedselkeuze en mogelijke oorzaken [PDF]

, 2006
Bruinvissen komen in steeds grotere aantallen voor in de Nederlandse (kust)wateren. In de periode 1960␂ 1985 was de bruinvis vrijwel uitgestorven in Nederland, maar de soort heeft een spectaculaire comeback gemaakt.

Shortlist Masterplan Wind Ship-based monitoring of seabirds and cetaceans [PDF]

During April 2010 – February 2011, monthly surveys of seabirds and marine mammals were conducted aboard ships engaged in plankton surveys. After many years of little or no effort in far offshore areas of the DCS, this series of surveys provided the first
