The Challenge: Treeshrews (order Scandentia) are small-bodied mammals endemic to South and Southeast Asia. Since it was first described in 1820, the Common Treeshrew (Tupaia glis) has had a complex taxonomic history that has led to widely variable estimates of diversity, misidentification of populations, and general confusion regarding it and closely related species. One result is that T. glis has...

The Challenge: Despite more than a century and a half of study, accurate understanding of the diversity North American mammalian species and the distribution of those species remains unrefined. Yet this understanding is essential for determining the conservation status of species, for mapping out potential disease reservoirs, and for understanding the response of species to habitat perturbation...

The Challenge: The postcranial skeletons of mammals exhibit tremendous variation in form that partly relates to phylogeny (who a particular species is related to) and partly to locomotory function (how that species moves through its environment). Understanding the contributions of these two factors is important because phylogenetic characters assist in working out evolutionary relationships...

The Challenge: Ancient Egyptians mummified animals for a variety of reasons, not the least of which was as votive offerings to certain deities. Among the six species of shrews that have been identified as mummies, one is now extinct, one is no longer occurs in Egypt, and the remaining four have more restricted distributions in the country. One of the latter species also exhibits significantly...

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...

This project aims to understand the factors driving breeding success of multiple waterbird species, with special emphasis on Least and Common Terns (two species of concern) on Poplar Island Environmental Restoration Project.

The U.S. Geological Survey Upper Midwest Environmental Sciences Center is developing deep learning algorithms and tools for the automatic detection, enumeration, classification, and annotation of seabirds and other marine wildlife from digital aerial imagery — advancing cutting-edge research in collaboration with the Bureau of Ocean Energy Management (BOEM), the U.S. Fish and Wildlife Service (FWS...

USGS researchers assessed trends in non-native mammalian predator trapping methods designed to protect endangered ʻuaʻu and nēnē at Haleakalā National Park, Hawaiʻi.

USGS scientists and partners are studying how growing goose populations in the California Central Valley wintering areas are affecting ducks and other waterfowl.

The range expansion of the North American beaver ( Castor canadensis) has implications for water quality, aquatic ecosystems, and fisheries in Arctic streams.

WARC researchers will estimate the density and distribution of bobcats in relation to environmental variables through the development of spatially explicit capture-recapture and occupancy models.

The Prairie Pothole Region (PPR) covers parts of five states and three Canadian provinces. The region contains millions of wetlands that annually produce 50-80% of the continent’s duck population. Previous modeling efforts indicated that climate change would result in a shift of waterfowl habitat from the central PPR to the southeast PPR where the majority of wetlands have been drained. However...
