Freshwater populations of typically marine species present unique opportunities to investigate biodiversity, evolutionary divergence, and the adaptive potential and niche width of species. A few pinniped species have populations that reside solely in freshwater. The harbour seals inhabiting Iliamna Lake, Alaska constitute one such population.

- Ice-associated seals depend on sea ice for essential activities such as pupping and resting, particularly during the spring months when the ice starts to melt.
- Climate change poses a significant threat to these seals by diminishing the habitat they rely on, making accurate population abundance estimations increasingly necessary for monitoring their conservation status.
- The study utilized satellite-linked bio-loggers to analyze seal behavior, focusing on bearded, ribbon, and spotted seals, to provide data that helps correct aerial survey counts by accounting for those seals that are in water and not visible.
Polar bears are of international conservation concern due to climate change but are difficult to study because of low densities and an expansive, circumpolar distribution. In a collaborative U.S.
View Article and Find Full Text PDFSouthern Ocean ecosystems are under pressure from resource exploitation and climate change. Mitigation requires the identification and protection of Areas of Ecological Significance (AESs), which have so far not been determined at the ocean-basin scale. Here, using assemblage-level tracking of marine predators, we identify AESs for this globally important region and assess current threats and protection levels.

- The Retrospective Analysis of Antarctic Tracking Data (RAATD) is a collaborative project aiming to consolidate tracking data for various Antarctic predators to pinpoint Areas of Ecological Significance.
- This initiative enhances our understanding of ecosystem dynamics in the Southern Ocean and aids in predicting how predator distributions may change in response to climate change.
- The publicly accessible dataset includes information from over 70 contributors, featuring 17 predator species and tracking over 2.9 million locations since the 1990s.
