Negative long term effects on harbour porpoises from a large scale offshore wind farm in the Baltic—evidence of slow recovery

open access: yesEnvironmental Research Letters, 2012
Offshore wind farms constitute a new and fast growing industry all over the world. This study investigates the long term impact on harbour porpoises, Phocoena phocoena , for more than 10 years (2001–12) from the first large scale offshore wind farm in ...

Applicability of cetacean microsatellite primers in the Yangtze finless porpoise

open access: yes, 2004
Application of microsatellites in the Yangtze finless porpoise ( Neophocaena phocaenoides asiaeorientalis) has not been reported. In this study amplification of microsatellites were performed in DNA samples of the Yangtze finless porpoise population by ...

The Intellect of Porpoises [PDF]

open access: yesNature, 1873

And yet, since we have ceased to credit the story of Arion, it is hard to believe that porpoises are much troubled with intellect.”

Integrating Porpoise and Cod Management: A Comparison of Days-at-sea, ITQs, and Closures

open access: yes
The purpose of this study is to determine if management measures based on effort reductions, in particular days-at-sea (DAS) controls, can approach a harbor porpoise individual transferable quotas (ITQ) program in terms of efficiency.
