High field metabolic rates of wild harbour porpoises [PDF]
ABSTRACTReliable 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 for measuring FMR are difficult to use on free-ranging cetaceans whose FMR may deviate substantially from scaling predictions

Testicular morphology and spermatogenesis in harbour porpoises (Phocoena phocoena) [PDF]
Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the present study was to report changes in the histological appearance of the testicular morphology of neonatal and juvenile harbour porpoises during ...

Large‐Scale Passive Acoustic Monitoring Data Shows Seasonal and Diel Diversity in Foraging Behaviour of Harbour Porpoises Within Their Distributional Range in the Northeast Atlantic [PDF]
Latitudinal gradient can influence ecosystem dynamics and species distribution, yet the influence on some aspects, such as intra‐species diversity, is less well understood.

Loop-mediated isothermal amplification (LAMP) assay-A rapid detection tool for identifying red fox (Vulpes vulpes) DNA in the carcasses of harbour porpoises (Phocoena phocoena). [PDF]
Carcasses of wild animals are often visited by different scavengers. However, determining which scavenger caused certain types of bite marks is particularly difficult and knowledge thereof is lacking.

Comparing Distribution of Harbour Porpoises (Phocoena phocoena) Derived from Satellite Telemetry and Passive Acoustic Monitoring. [PDF]
Cetacean monitoring is essential in determining the status of a population. Different monitoring methods should reflect the real trends in abundance and patterns in distribution, and results should therefore ideally be independent of the selected method.

The effects of marine traffic on the behaviour of Black Sea harbour porpoises (Phocoena phocoena relicta) within the Istanbul Strait, Turkey. [PDF]
Marine traffic is threatening cetaceans on a local and global scale. The Istanbul Strait is one of the busiest waterways, with up to 2,500 vessels present daily.

Spatial Dynamics of Harbour Porpoise Phocoena phocoena Relative to Local Hydrodynamics and Environmental Conditions [PDF]
Understanding the spatial dynamics of harbour porpoise (Phocoena phocoena) is crucial for effective conservation and management. The study presents a multidisciplinary approach to modelling and analysing the site occurrence and habitat use of Phocoena ...

Harbour porpoises respond to climate change [PDF]
AbstractThe effects of climate change on marine ecosystems and in particular on marine top predators are difficult to assess due to, among other things, spatial variability, and lack of clear delineation of marine habitats. The banks of West Greenland are located in a climate sensitive area and are likely to elicit pronounced responses to oceanographic

Bycatch is a significant cause of population declines of marine megafauna globally. While numerous bycatch mitigation strategies exist, acoustic alarms, or pingers, are the most widely adopted strategy for small cetaceans.

Porpoises and their prey : Diet and foraging behaviour of Belt Sea harbour porpoises
The harbour porpoise (Phocoena phocoena) is a small toothed whale with a mainly coastal distribution in the northern hemisphere. As a marine top predator, the species can act as an indicator for early warning signs of ecosystem changes. At the same time, harbour porpoises are globally threatened by human activities and in need of conservation ...
