Algorithms are presented for the accurate time of arrival difference estimation of high frequency narrow band echolocation clicks from Harbor Porpoise. These clicks typically have a center frequency of around…
...Harbor porpoises have been reported as an uncommon species in Kotzebue Sound during the ice-free months of June through October (Frost & Lowry, 1990), but their presence in Kotzebue Sound…
Acoustic deterrent devices (ADDs) are used to deter seals from aquacultures but exposure of harbour porpoises (Phocoena phocoena) occurs as a side-effect. At construction sites, by contrast, ADDs are used…
Harbor porpoises (Phocoena phocoena) in the North and Baltic Seas are exposed to anthropogenic influences including acoustic stress and environmental contaminants. In order to evaluate immune responses in healthy and…
Harbour porpoises (Phocoena phocoena) in the North Sea live in an environment heavily impacted by humans, the consequences of which are a concern for their health. Autopsies carried out on…
During the last few years, the Western Black Sea coast has documented increase in the number of stranded marine mammals, particularly the harbour porpoise (Phocoena phocoena). This species is a…
Naval sonar systems produce signals that may affect the behavior of harbor porpoises (Phocoena phocoena), and behavioral responses may be influenced by the received signal and by the signal-to-noise ratio…
Echolocating mammals generally target individual prey items by transitioning through the biosonar phases of search (slow-rate, high-amplitude outputs), approach (gradually increasing rate and decreasing output amplitude) and buzzing (high-rate, low-amplitude…
Studies on odontocetes (e.g., porpoises) have revealed that these animals may adaptively use vision. The present study examined the contributions of vision to the approaching behavior of the harbor porpoise…
Podoplanin (PDPN)/T1 alpha is known as a specific marker of lymphatic endothelial cells and type I alveolar cells. Sensitive and specific monoclonal antibodies (mAbs) for PDPN are needed for immunohistochemical…
