Reply to the discussion by Pilfold “Polar bear mass change confirms hyperphagia follows ringed seal whelping” Reply to the discussion by Pilfold “Polar bear mass change confirms hyperphagia follows ringed seal whelping”
The spring is a critical period when polar bears (Ursus maritimus Phipps, 1774) are thought to have peak access to seals and acquire the majority of their annual energy requirements during a period of hyperphagia. Pagano et al. (Pagano A.M., Atkinson S.N., and Archer L.C. 2025. Arctic Science.11:1-14. doi:10.1139/as-2024-0051) examined the intra-seasonal changes in body mass of 31 polar...
Amphibian diversity of the western Colorado canyonlands including potential threats from nonnative bullfrogs and disease Amphibian diversity of the western Colorado canyonlands including potential threats from nonnative bullfrogs and disease
Throughout the canyons of the Colorado and Uncompahgre Plateaus, water is a limited resource for wildlife, with patchy distribution and seasonal availability. Tributary creeks within these canyons drain into mainstem rivers, providing habitat and breeding sites for native amphibians. Yet, little is known about the diversity and distribution of amphibians that live in these harsh, dynamic
U.S. Geological Survey Pollinator Science Strategy, 2025–35—A Review and Look Forward U.S. Geological Survey Pollinator Science Strategy, 2025–35—A Review and Look Forward
This “U.S. Geological Survey Pollinator Science Strategy, 2025–35—A Review and Look Forward” (“Pollinator Science Strategy”) describes the science vision of the U.S. Geological Survey (USGS) to support management, conservation, and policy decisions on animal pollinators and their habitats. As the science arm of the Department of the Interior, the USGS has a primary role in providing...

Polar Bear Research
Polar bears ( Ursus maritimus) are one of 4 marine mammal species managed by the U.S. Department of Interior. The USGS Alaska Science Center leads long–term research on polar bears to inform local, state, national and international policy makers regarding conservation of the species and its habitat. Our studies, ongoing since 1985, are focused on population dynamics, health and energetics...
Terrestrial Mammal Research
Understanding the population dynamics, predator/prey relationships and habitat ecology of terrestrial mammals, such as caribou and muskoxen, is critical for the management of these species and their habitats in Alaska.
