Ringed seal (Pusa hispida) seasonal movements, diving, and haul‐out behavior in the Beaufort, Chukchi, and Bering Seas (2011–2017) [PDF]
Ecology and Evolution, 2020 Continued Arctic warming and sea‐ice loss will have important implications for the conservation of ringed seals, a highly ice‐dependent species. A better understanding of their spatial ecology will help characterize emerging ecological trends and inform ...

Modeling Ringed and Bearded Seal Future Habitats Indicates Stability, Shifts, and Refugia. [PDF]
Glob Chang BiolEvery year, ringed seals and bearded seals rely on specific ice and snow conditions to support events such as feeding or reproduction. With Earth System Models, we simulate habitat over 1850–2100, revealing a relatively stable past habitat contrasting with rapid regional shifts in contemporary simulations and future projections.

Top-Down and Bottom-Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology. [PDF]
Ecol LettThis study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

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

Molting phenology of a lacustrine ringed seal, Pusa hispida saimensis
Ecology and Evolution, 2022 The timing and effect of a range of environmental variables on the annual molt of ringed seals (Pusa hispida saimensis) in Lake Saimaa were studied in 2013–2019. Molting patterns were investigated by mixed models run on photoidentification data collected

Polar Research, 2021 The ringed seal is a small phocid seal that has a northern circumpolar distribution. It has long been recognized that body size is variable in ringed seals, and it has been suggested that ecotypes that differ in size exist.

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.

Demographic, ecological, and physiological responses of ringed seals to an abrupt decline in sea ice availability [PDF]
PeerJ, 2017 To assess whether demographic declines of Arctic species at the southern limit of their range will be gradual or punctuated, we compared large-scale environmental patterns including sea ice dynamics to ringed seal (Pusa hispida) reproduction, body ...

Stable ringed seal (Pusa hispida) demography despite significant habitat change in Svalbard, Norway
Polar Research, 2020 Ringed seals, which are small phocid seals, range across the circumpolar Arctic, and have evolved in close association with sea ice and depend on it for all aspects of their life history.
