Southern California's fire ecology is unlike that of anywhere else in the United States. Fire control strategies developed for mountain forests don't have the same results here. So can science help uncover new answers to help Southern California communities manage and live with wildfires?

Devastation from the 1913 flood is shown primarily through photographs taken during the March 1913 flood. In the aftermath of the 1913 flood, State and Federal funds were allocated for the installation of a streamgage network to monitor the water level and flow of Ohio's rivers and streams.

Bat Activity Behind Turbine Rotor Swept Area

This clip shows a bat (not identified to species) flying near a turbine as imaged with a thermal camera. The recording shows the bat making numerous repeated passes behind the rotor swept area of a turbine. This activity is of particular interest to researchers because it provides a window into behavior that places bats at risk from turbine strikes.

Bat Investigation of Nacelle and Turbine Rotors

This clip shows a bat (not identified to species) flying near a turbine as imaged with a camera sensitive to near infrared light. The bat flies in rapidly from the top left, then turns and flies into the spinning rotor blades of the turbine. The bat appears to be deflected upwards by the blades and escapes a direct strike.
