Relatively little is known about the distribution and diversity of marine mammals around offshore anthropogenic structures. We present results obtained from incidental sightings of marine mammals around oil and gas…
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. This is the…
Marine habitat heterogeneity underpins species distribution and can be generated through interactions between physical and biological drivers at multiple spatiotemporal scales. Passive acoustic monitoring (PAM) is used worldwide to study…
Hearing is the primary sensory modality for toothed whales, but it is not known at which age it is fully developed. For newborn calves, hearing could fill an important function…
The mechanism by which odontocetes produce sound is unique among mammals. To gain insight into the physiological properties that support sound production in toothed whales, we examined myoglobin content ([Mb]),…
Throughout their range, marine mammals are vulnerable to incidental capture in fishing gear. Bycatch is a particularly important issue for cetaceans, which generally have lower potential rates of population growth…
...Recently, Wisniewska et al. (2016) used high-resolution digital acoustic tags (DTAGs) to monitor the foraging behavior of five harbor porpoises in Danish waters. This approach provided detailed observations on the…
Complex foldings of the vaginal wall are unique to some cetaceans and artiodactyls and are of unknown function(s). The patterns of vaginal length and cumulative vaginal fold length were assessed…
Contact zones between ecotypes are windows for understanding how species may react to climate changes. Here, we analysed the fine-scale genetic and morphological variation in harbour porpoises (Phocoena phocoena) around…
