Great Lakes Deepwater Monitoring

USGS work on assessing the status and trends of deepwater aquatic communities in the Great Lakes provides information fisheries managers are using to see if management actions (such as reducing invasive sea lampreys) have helped important commercials fisheries (such as lake trout) recover. Our monitoring program helps guide decision-making in effective directions for a variety of stakeholders...

Pollinators are crucial contributors to our environment and society by enhancing plant diversity in wild lands and providing food for humans in agricultural settings. Some three-fourths of all native plants in the world require pollination by an animal, most often an insect, and most often a native bee.

North American Breeding Bird Survey (BBS)

With 2015 marking its 50th anniversary, the Breeding Bird Survey (BBS) continues to provide critical science-based estimates of population change on more than 600 continental bird species annually to improve our understanding of how these federally entrusted species respond to environmental variation and ecosystem change.

National Phenology Network (NPN)

The USA National Phenology Network is a national-scale science and monitoring initiative focused on phenology, which is the study of seasonal life-cycle events such as leafing, flowering, reproduction and migration, as a tool to understand how plants, animals and landscapes respond to environmental variation and change.

Population Genetics and Emergency Management of Two Kauai Island Endangered Species

The Challenge: The Akeke’e (Loxops caeruleirostris) and the Akikiki (Oreomystis bairdi), two species of Hawaiian honeycreeper, are critically endangered bird species endemic to high elevation ohia forests on the Hawaiian island of Kauai.  Both species have suffered severe population declines and range contractions in recent decades.  Akeke’e are currently thought to number ca. 950 wild...

Analyzing the Gut Microbiome of Urban Canada Geese

The Challenge: The Canada Goose Branta canadensis was historically a highly migratory species.  However, this species has recently established resident populations in urban, suburban, and agricultural areas in many parts of the U.S., including the Chesapeake Bay region.  The enormous success of these populations has led to consideration of this species as a nuisance, largely due to its...

What Ancient Egyptian Shrew Mummies Reveal About Small Mammal Responses to Climate Change

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...

How Mammals Move: Locomotory Function in the Soricidae

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,...
