Extreme moulting site fidelity of the Saimaa ringed seal
Site fidelity is commonly observed in pinnipeds and has direct consequences for individual space use and population dynamics. Here, we used...

Haul-out site use by Ladoga ringed seal (Pusa hispida ladogensis) on the islands of the Valaam Archipelago
In June–July 2020, a study of the Ladoga ringed seal haul-out use pattern was carried out on the islands of the Valaam Archipelago, Lake Ladoga, in...

Complementary diet analyses reveal intraspecific and temporal variation in ringed seal (Pusa hispida) foraging in the Canadian high arctic
Warming ocean temperatures and loss of Arctic sea ice have contributed to shifts in the distribution of endemic forage species important to the diets...

The Ringed Seal: Behavioral Adaptations to Seasonal Ice and Snow Cover
Behavioral adaptations for maintaining breathing holes in sea ice and lairs in the overlying snow cover allow ringed seals to occupy sea ice...

Peripheral Blood Cell Composition of Baikal Seal Phoca sibirica
AbstractThe cellular composition of the peripheral blood of the Baikal seal Phoca sibirica (Gmelin, 1788) has been studied. Various cells have been...

Genomic evidence uncovers inbreeding and supports translocations in rescuing the genetic diversity of a landlocked seal population
Fragmentation of isolated populations increases the risk of inbreeding and loss of genetic diversity. The endemic Saimaa ringed seal ( Pusa hispida...

Matching individual Ladoga ringed seals across short-term image sequences
Automated wildlife reidentification has attracted increasing attention in recent years as it provides a non-invasive tool to identify and to track...

Genetic Characteristics of the Baikal Seal Pusa sibirica Population
AbstractNucleotide sequence diversity in two mtDNA loci (the cytochrome b gene and the control region) was for the first time studied in the Baikal...

The Antarctic Weddell seal genome reveals evidence of selection on cardiovascular phenotype and lipid handling
The Weddell seal ( Leptonychotes weddellii ) thrives in its extreme Antarctic environment. We generated the Weddell seal genome assembly and a...

Extended Molting against the Background of Climate Warming Explains the Emergence of the Baikal Seal (Pusa sibirica, Pinnipedia) onto Coastal Rookeries
AbstractAn analysis of the video films taken at a Baikal seal rookery in the period 2011–2021 on Dolgii Island (Ushkan’i Islands, northern Lake...

The First Record of a New Haul-Out Site of Ringed Seals, Pusa hispida (Schreber, 1775) (Phocidae), on Sakhalin Island
AbstractA new coastal haul-out site of ringed seals, Pusa hispida (Schreber, 1775), has been found on the coast of Sakhalin Island. Information on...

Ringed seal (Pusa hispida) diet on the west coast of Spitsbergen, Svalbard, Norway: during a time of ecosystem change
Global warming is causing Atlantification of water masses and concomitant changes in food webs in the Barents Sea region. To determine whether...

Linking movement and dive data to prey distribution models: new insights in foraging behaviour and potential pitfalls of movement analyses
BackgroundAnimal movement data are regularly used to infer foraging behaviour and relationships to environmental characteristics, often to help...

Whaling, Seal Hunting and the Effect of Fisheries on Marine Mammals
There are various types of interactions between marine mammals and fisheries, and their presence in the same area inevitably leads to conflicts....

Assessing the performance of open-source, semi-automated pattern recognition software for harbour seal (P. v. vitulina) photo ID
Photographic identification (photo ID) is a well-established, non-invasive, and relatively cost-effective technique to collect longitudinal data from...

The Weddell Seal: Eco-Physiological Adaptations to a High-Latitude Seasonal Environment
As the world’s southernmost living mammal, the Antarctic Weddell seal (Leptonychotes weddellii) experiences large shifts in light levels,...
