Complex Origins and History of the Relict Fennoscandian Ringed Seals [PDF]
Ecology and EvolutionSpatiotemporal environmental heterogeneity is a major evolutionary driver, which can cause profound phylogeographic complexity, particularly at the periphery of species ranges.

Seasonal activity budget of adult baltic ringed seals. [PDF]
PLoS ONE, 2008 Although ringed seals are important components in oceanic and fresh water ecosystems at high latitudes, little is known about how they exploit these harsh environments.

DNA barcoding reveals different cestode helminth species in northern European marine and freshwater ringed seals [PDF]
International Journal for Parasitology: Parasites and Wildlife, 2021 Three subspecies of the ringed seal (Pusa hispida) are found in northeastern Europe: P. h. botnica in the Baltic Sea, P. h saimensis in Lake Saimaa in Finland, and P. h. ladogensis in Lake Ladoga in Russia.

The numbers of ringed seals (Phoca hispida) in Baffin Bay and associated waters
NAMMCO Scientific Publications, 1998 The size of the population of ringed seals (Phoca hispida) inhabiting Baffin Bay and associated waters was estimated by two methods. An approximate model of the energetics of the polar bear (Ursus maritimus) estimated an energetic need of about 16,000 MJ/

Variation in Ringed Seal (Pusa hispida) Density Along a Latitudinal Gradient of Sea‐Ice Conditions [PDF]
Ecology and EvolutionAnthropogenic climate warming is triggering poleward species redistributions, highlighting the importance of understanding how species distributions and abundance vary along latitudinal gradients.

Spatial overlap of sea ice-associated predators and prey in western Hudson Bay. [PDF]
PLoS ONESpatio-temporal distribution of species shapes community structure and ecosystem function, yet the mechanisms driving biological hotspots remain unclear in dynamic environments like sea ice. We computed Getis-Ord (Gi*) distribution hotspots based on four

Ringed Seal (Pusa hispida) Haul‐Out Behavior and Emergence Timing in the Bering, Chukchi, and Beaufort Seas [PDF]
Ecology and EvolutionRinged seals are ice‐associated marine mammals that excavate lairs in snowdrifts on sea ice during winter for resting and pupping. Before lairs melt in the spring, seals shift from predominantly hauling out in lairs to predominantly hauling out on the ...

In search of virus carriers of the 1988 and 2002 phocine distemper virus outbreaks in European harbour seals [PDF]
, 2008 European harbour seal (Phoca vitulina) populations decreased substantially during the phocine distemper virus (PDV) outbreaks of 1988 and 2002. Different hypotheses have stated that various seals and terrestrial carnivore species might be the source of ...
