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...

Redesigning the Eastern Breeding Waterfowl Population and Habitat Survey
USGS and partners are revising the design of a key waterfowl survey to increase management efficiency and cost-effectiveness, and inform annual harvest regulations in the U.S. and Canada.
Evaluating the Design of the Waterfowl Breeding Population and Habitat Survey
The Waterfowl Breeding Population and Habitat Survey (WBPHS) is a primary source of waterfowl population status and trend information for management of ducks in North America. The survey has not been reviewed in several decades, and since the last review new analysis approaches and information needs have created a need to reassess the design, scope of inference, and analysis of the survey to...
