Tracking bats and their prey in the aerosphere

Using Doppler weather radar, Winifred Frick from the University of California, Santa Cruz, and colleagues explored the role of atmospheric conditions and insect prey presence in bat behavior. Specifically, the researchers used weather tracking technology to determine the regional patterns of migratory arrival and departure times of Brazilian free-tailed bats in Texas. They also found that weather conditionssuch as surface temperature, precipitation and windplayed a significant role in when these bats emerged from caves and from under bridges in Texas.

"For quite some time, the flight and foraging behavior of nocturnal aerial animals has been difficult to track," said Frick, who will be presenting this research with colleagues at ESA's 2011 Annual Meeting in Austin. "Now we are able to study radar visualizations to observe animal behavior while they interact in the aerosphere."

The presentation "Meteorological drivers of predator-prey interactions in the aerosphere" led by Winifred Frick, University of California, Santa Cruz, will be held Thursday, August 11, 2011 at 2:30 pm during the "Aeroecology: An Emerging Discipline" organized oral session.

Other presentations on aeroecology include:

"Impacts of wind-energy development on bats: Challenges and solutions" by Edward Arnett, Bat Conservation International, Austin; "Large-scale navigational map in a flying mammal: Evidence from GPS tracking of Egyptian fruit bats" led by Nachum Ulanovsky, Weizmann Institute of Science, Rehovot, Israel; "Radar aeroecology: The need for cohesive radar studies of organisms in the aerosphere" led by Phillip Chilson, University of Oklahoma; and "Integrating novel technologies to understand the flight behavior of bats at different temporal and spatial scales" led by Nickolay Hristov, Winston-Salem State University.
