This is an introductory video to an adaptive management approach for the invasive plant Phragmites australis in the Great Lakes basin. An adaptive management framework is an iterative process of robust decision making aimed at reducing uncertainty over time, for a variety of stakeholders with differing backgrounds and interests, via system monitoring.

This short clip is representative of a large amount of video footage of an adult female polar bear, equipped with a point of view camera, that is used by scientists to study polar bear behavior and feeding rates.

So many unknowns and so many potentials.

This video describes USGS research utilizing remote thermal imaging cameras to study the extent and impact of mange on wolves in Yellowstone National Park.

This is a recorded presentation describing a statistical software package called "Evidence of Absence" that can be used to provide evidence of compliance with incidental take permits.

This video was shot in Three Sisters Springs at the Crystal River National Wildlife Refuge, Florida. The footage was captured using a GoPro while conducting health check-ups and taking photography for population research on Jan. 30, 2014.

The USGS Northern Prairie Wildlife Research Center, located in the Northern Great Plains state of North Dakota highlights their current and ongoing research on land use and pollinator health.

Heading out to take water chemistry samples for a study on permafrost in the Yukon River Basin. The study examined the chemical and hydrological changes occurring in the basin due to permafrost loss.
