Exploitation of renewable energy from offshore wind farms is substantially increasing worldwide. The majority of wind turbines are bottom mounted, causing high levels of impulsive noise during construction. To prevent…
The preference for coastal habitats makes the harbour porpoise, Phocoena phocoena, vulnerable to fisheries conflicts and hence prone to die due to entangling in fishing nets. An opportunistic sampling of…
Echolocation signals emitted by odontocetes can be roughly classified into three broad categories: broadband echolocation signals, narrowband high-frequency echolocation signals, and frequency modulated clicks. Previous measurements of broadband echolocation signal…
The exposure of marine mammals to phthalates has received considerable attention due to the ubiquitous occurrence of these pollutants in the marine environment and their potential adverse health effects. The…
Polychlorinated biphenyls (PCBs) are a group of 209 persistent and bio-accumulative toxic pollutants present as complex mixtures in human and animal tissues. Harbor porpoises accumulate some of the highest levels…
The aim of the present study was to assess the effectiveness of pinger devices on the Black-Sea harbour porpoises Phocoena phocoena relicta. The study was carried out in Sinop, Turkey,…
The need to minimize bycatch of toothed whales (odontocetes) in gillnets has long been recognized, because they are often top predators and thus essential to ecosystem resilience. It is likely…
The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well…
Harbor porpoises are typically seen in small groups of 1–3 individuals, with aggregations of 20+ individuals treated as rare events. Since the 1990s, the harbor porpoise population in the Salish…
The availability of reliable information on the abundance and distribution of threatened species is fundamental to evaluating their conservation status and taking the necessary measures to implement effective management. The…
