Herpesviruses including novel gammaherpesviruses are widespread among phocid seal species in Canada [PDF]

, 2016
Little is known about herpesviruses in Canadian pinnipeds. We measured prevalence of antibodies to herpesviruses in the sera from Canadian phocid seals by an indirect enzyme-linked immunosorbent assay.

Intraspecific and temporal variability in the diet composition of female polar bears in a seasonal sea ice regime

Arctic Science, 2017
Predator foraging behaviour is influenced by a suite of intrinsic and extrinsic factors, including energetic requirements, resource availability, and habitat conditions.

Serologic survey for phocid herpesvirus-1 and -2 in marine mammals from Alaska and Russia. [PDF]

, 1997
Blood samples were collected from 1,042 marine mammals off the coast of Alaska (USA) and Russia during the period 1978 to 1994. Eight species of pinnipeds were represented. Sera were tested for presence of neutralizing antibodies to both the PB84 isolate

Summing the strokes: energy economy in northern elephant seals during large-scale foraging migrations. [PDF]

, 2015
BackgroundThe energy requirements of free-ranging marine mammals are challenging to measure due to cryptic and far-ranging feeding habits, but are important to quantify given the potential impacts of high-level predators on ecosystems.

Stomach temperature records reveal nursing behaviour and transition to solid food consumption in an unweaned mammal, the harbour seal pup (Phoca vitulina) [PDF]

, 2014
Knowledge of milk transfer from mother to offspring and early solid food ingestions in mammals allows for a greater understanding of the factors affecting transition to nutritional independence and pre-weaning growth and survival.

Assessment of impacts and potential mitigation for icebreaking vessels transiting pupping areas of an ice-breeding seal [PDF]

, 2017
Icebreaker operations in the Arctic and other areas are increasing rapidly to support new industrial activities and shipping routes, but the impact on pinnipeds in these habitats is poorly explored.

Shape of Aquatic Animals and Their Swimming Efficiency

Journal of Marine Sciences, Volume 2014, Issue 1, 2014., 2014
The best swimmers have a streamlined shape that ensures an attached flow pattern and a laminar boundary layer at rather large values of the Reynolds number. Simple expressions may be obtained for the volumetric drag coefficient of an ideal body of revolution under laminar unseparated flow conditions together with estimations of a critical value of the ...

Phocine distemper Virus: Current knowledge and future directions [PDF]

, 2014
Phocine distemper virus (PDV) was first recognized in 1988 following a massive epidemic in harbor and grey seals in north-western Europe. Since then, the epidemiology of infection in North Atlantic and Arctic pinnipeds has been investigated.

Ecological and economic consequences of introductions of exotic wildlife (birds and mammals) in Germany

Wildlife Biology, Volume 2, Issue 3, Page 205-211, September 1996., 1996
This paper describes the ecological and economic consequences of introduced bird and mammal species for fauna, flora and habitats, for forestry and agriculture and also for other parts of the land developed and cultivated by man. The results presented are based on enquiries to various institutions for the environment, nature conservation, agriculture ...
