While the Hawaiian avian disease system has been well-studied in the forests of the older section of Hawai‘i Volcanoes National Park (HAVO), and in many other locations throughout the state, nothing was known about avian disease in the new Kahuku Unit of Hawai‘i Volcanoes National Park and the adjacent Kau Forest Reserve. The high elevation forests of Kahuku are the only habitat located on...
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...
The team's long term goal is:
- Examine the causes, fates, exposures, biological accumulation, and adverse effects (including sublethal effects) of environmental contaminants on animal (largely bird) populations.
The Status and Trends Program responds to the monitoring and information needs and requirements of
resource management bureaus within Interior and other science and resource management organizations
by working with them to design, develop, and support research, monitoring, and assessment activities
required for resource management and policy decisions by a variety of...
Bird banding is used to study the movement, behavior, and survival of birds. In North America, bird banding is a joint program between USGS and the Canadian Wildlife Service.
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.
The Wyoming Landscape Conservation Initiative (WLCI) is a long-term, science-based program focused on assessing, conserving, and enhancing fish and wildlife habitats while facilitating responsible energy development through local collaboration and partnerships.
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.
Common loons often migrate several hundred miles to reach coastal waters during fall migration. Information about this part of the loon's life history is not well known.
The use of satellite telemetry allows biologists to track loon movements through distant migrations and during winter. A transmitter attached to a radiomarked loon periodically sends a signal which is detected by a...
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.
Rapid Ohia Death (ROD) is an emerging and rapidly spreading disease of ohia (Metrosideros polymorpha), a keystone native forest tree in the Hawaiian Islands. The disease is highly pathogenic in native ohia and can lead to significant mortality once symptoms become evident. This emerging pathogen is a significant threat to native forests throughout the state because of its potential...
Striped bass (Morone saxatilis) displaying ulcerative skin lesions and chronic wasting, both typical clinical signs of mycobacteriosis, a bacterial disease that is problematic among many types of fishes around the world.
