Time and tide: Seasonal, diel and tidal rhythms in Wadden Sea Harbour porpoises (Phocoena phocoena).

open access: yesPLoS ONE, 2019
Odontocetes have evolved a rich diversity of prey- and habitat-specific foraging strategies, which allows them to feed opportunistically on locally and temporally abundant prey.

Follow-up study after four years shows reduced deterrence effect of pingers on harbour porpoises in Norwegian gillnet fishery

open access: yesNAMMCO Scientific Publications
We report results from follow-up field trials testing acoustic deterrents (pingers) as a measure to reduce harbour porpoise (Phocoena phocoena) by-catch rates in coastal gillnet fisheries in Norway.

A negative trend in abundance and an exceeded mortality limit call for conservation action for the Vulnerable Belt Sea harbour porpoise population

open access: yesFrontiers in Marine Science
The management and conservation of biodiversity relies on information on both the abundance of species and the potential impact of threats. Globally, one of the largest threats towards marine biodiversity is bycatch in fisheries.

Monitoring life history parameters in harbour porpoises

open access: yes, 2011
No abstracts are to be cited without prior reference to the author.Implementation of the Ecosystem Approach to Fisheries Management will require monitoring of the status and trends in populations of top predators such as dolphins and porpoises. Existing monitoring, as required under (for example) the Habitats Directive typically involves collection of ...

The times they are a changin’: Temporal patterns in small cetacean abundance in the northeast Atlantic

open access: yesEcological Indicators
Conserving marine species effectively requires spatially and temporally explicit knowledge of their abundance and distribution for assessing potential impacts (e.g., from fishery bycatch, anthropogenic sound, ship strikes) over different spatial and ...

Cetacean Strandings along the Bulgarian Coast of the Black Sea in 2010–2022

open access: yesOceans
Cetacean strandings are valuable sources of data about their life history, health status, population trends, and impact of threats. We examined the strandings along the Bulgarian coast of the Black Sea for a period of 13 years from 2010 to 2022.
