The Importance of Individual Body Condition in Mammalian Behavioural Responses to Disturbance
Body condition, shaped by the balance between energy demands and reserves, predictably shapes mammalian disturbance responses. Poor‐condition individuals adopt needs‐based strategies, accepting greater risks to meet immediate energetic needs, while good‐condition individuals follow asset‐protection strategies, minimizing risks to protect their survival

Bycatch as a potential threat to harbour porpoises (Phocoena phocoena) in Polish Baltic waters
Sixty-two verified reports obtained in the years 1990-1999 on the bycatch, strandings and sightings of harbour porpoises in the Polish Baltic were analysed in this study. In relative terms the highest number of reports (22) was noted in Puck Bay.

ABSTRACT Understanding how demographic dynamics interact with environmental heterogeneity is central to explaining patterns of genomic variation in the marine realm. Indo‐Pacific bottlenose dolphins (Tursiops aduncus) occur along most of the Australian coastline, from tropical to temperate waters, encompassing pronounced differences in temperature ...

Sex and size matter:foraging ecology of offshore harbour porpoises in waters around Greenland
Individuals of different sex or age can vary in their prey and habitat resource use due to differences in behaviour, life history, energetic need, or size.

Grey seal attacks on harbour porpoises in the Eastern Scheldt: cases of survival and mortality [PDF]
In the southern North Sea, hundreds of mutilated harbour porpoise carcasses (Phocoena phocoena) are found each year on beaches. Recent studies have confirmed that these concern the remains of predation by grey seals (Halichoerus grypus).

Abstract Estuaries host important populations of marine megafauna. These environments provide shelter from the open ocean alongside a myriad of bathy‐hydographic features where interactions between topography and tidal flows may enhance foraging opportunities.

European harbour seal (Phoca vitulina) populations decreased substantially during the phocine distemper virus (PDV) outbreaks of 1988 and 2002. Different hypotheses have stated that various seals and terrestrial carnivore species might be the source of ...

Fatty Acid Composition in Blubber, Liver, and Muscle of Marine Mammals in the Southern Baltic Sea
To date, only limited results on the fatty composition in different tissues of the top predators in the Baltic Sea are available. In the current study, tissue samples of blubber, skeletal muscle, and liver from 8 harbour porpoise (Phocoena phocoena) and ...
