We developed a chemical analytical procedure for sampling, extracting and determining epidermal skin cortisol concentrations (SCCs) in the harbour porpoise (Phocoena phocoena) using gas chromatography–tandem mass spectrometry. In brief, this…
Similar to terrestrial mammals, male-female sexual behavior is significant for the survival and continuation of certain cetacean species. However, non-reproductive mating behaviors, i.e. homosexual behaviors and masturbation, are widespread in…
Airguns used in seismic surveys are among the most prevalent and powerful anthropogenic noise sources in marine habitats. They are designed to produce most energy below 100 Hz, but the…
The clicks of Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) from 7 individuals in the tank of Baiji aquarium, 2 individuals in a netted pen at Shishou Tian-e-zhou Reserve and 4…
The Expert Panel on Vaquita Acoustic Monitoring had its second meeting on April 28, 2015 to analyze the first four seasons (2011-2014) of the acoustic monitoring program. Results indicate an…
There are two porpoise stocks in the northern Black Sea: the north-western (Odessa Gulf) and northeastern (Crimean and Caucasian waters); in addition, another stock is in the Sea of Azov.…
(...) gray seal (Halichoerus grypus) consumption of harbor porpoises—whether predation or scavenging—might reflect a change in gray seal feeding habits in the southern North Sea (Haelters et al. 2012), where…
During recent decades, the 2 distinct harbour porpoise populations of the Baltic Sea have decreased sharply in abundance. The Baltic Proper population is down to a few hundred individuals and…
Ships and wind turbines generate noise, which can have a negative impact on marine mammal populations by scaring animals away. Effective modelling of how this affects the populations has to…
The construction of industrial offshore structures may lead to colonization by a variety of marine organisms resulting in locally enhanced biodiversity and biomass, which may then affect the habitat use…
