Avian Pathogens and Vectors - Kahuku Unit of Hawaii Volcanoes National Park

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...

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

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.

Common Loon Migration Study

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...

Pathways for Movement and Rate of Spread of Rapid ‘Ōhi‘a Death on the Island of Hawai‘i

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...
