Aquatic Mammals (2017)
Harbor porpoises (Phocoena phocoena) were rarely seen in San Francisco Bay prior to 2008 despite numerous marine mammal search efforts beginning in the 1970s. The species inhabited the bay historically…

This study investigated whether there is evidence of widespread niche partitioning based on environmental factors in the Black Sea and tested the hypothesis that physiographic factors may be employed as…
Wildlife Species Description and Significance The Pacific Harbour Porpoise (Phocoena phocoena vomerina) is the smallest cetacean in British Columbia (BC), ranging from 1.5 to 1.6 m and 45 to 60…
Analyses of animal species distribution in a neutral or minimally-interrupted habitat provide a baseline that is essential for assessment of population status, identification of key habitat, and conservation planning for…
A survey of helminths and ectoparasites, including epizoits, was conducted in narrow-ridged finless porpoises (Neophocaena asiaeorientalis) from Japanese five populations using dead stranded or incidentally caught animals. In total, 13…
Conventional spatial density models assume a constant relationship between densities and habitat covariates over some time period, typically a survey season. The estimated population size must change whenever total habitat…
The first assessment of cetacean density and abundance by linear transect survey was conducted in 2016 and 2017 in the shallowest coastal area of the Ukrainian sector of the north-western…
Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of…
Tidal-stream habitats present periodically fast-flowing, turbulent conditions. Evidence suggests that these conditions benefit top predators such as harbour porpoises Phocoena phocoena, presumably allowing them to optimise exploitation of prey resources.…
The study was conducted by examining stranded cetaceans while explicitly searching for dead marine mammals. Observations were made through covering transects along the Bulgarian Black Sea coast. The data collection…
