Barred owls (Strix varia) have expanded their geographic range from eastern to western North America. Their newly expanded range now completely overlaps that of the federally threatened northern spotted owl (S. occidentalis caurina).

This female Burmese python broke the records for her length -- 17 feet, 7 inches – and the number of eggs she contained: 87. She was first captured in Everglades National Park by USGS researchers in the spring of 2012, when they followed a "Judas snake" -- a male python with a transmitter -- and found her nearby in the bushes.

Amount of soil (about 200 mg) from which Geomyces destructans was cultured. This shows the small amount of soil needed to harbor live fungus and the threat that humans might pose in moving it around from cave to cave on their gear, boots, and clothing.

From 2012-2013, telemetry data were collected from nine eagles outfitted with a backpack holding a global positioning system-global system for mobile communications, or GPS-GSM, telemetry system. The telemetry system recorded and stored a GPS location every 15-minutes and sent the locations, via the GSM – or mobile phone – network, to a server once per day.

Researchers use a net to pull an endangered wild manatee onto the beach in order to conduct a physical examination. Information on manatee biology in Crystal River enables biologists to better understand the complex issues confronting this fragile species.

Research of the Montana Cooperative Fishery Research Unit will continue to focus on applied fisheries-management problems and issues. Our studies are initiated in response to the needs of the Cooperators and other management agencies and are designed to provide information useful in directly improving management of aquatic resources.
