Dr. Klimley oversees research conducted in the Biotelemetry Laboratory at UC Davis.  He has been involved in the development of many facets of animal tracking system from the origination of algorithms for inferring geographical position based on irradiance and magnetic field measurements to the creation of stand-alone receivers that detect the identity of species passing by carrying coded acoustic beacons.  Under his guidance,  undergraduates, graduate students, and staff utilize sophisticated electronic tagging equipment to study the physiology, behavior, and ecology of aquatic and terrestrial species. Members of the Biotelemetry Laboratory have conducted studies ranging from (1) use of two dimensional  VRAP and VPS arrays to study reproduction in abalones and white shark predation, (2) utilizing emg transmitters to record tails beats of trout  to record their energetic output during pulsed flow for electrical energy generation and 3-axis acceleration sensors to monitor anti-predator behavior in ant eaters,  and (3) satellite transmitters to record optimal foraging by brown bears and pop-up release satellite transmitters that recorded the diving behavior of hammerhead sharks.  Much of the work is conservation oriented in the Biotelemetry Laboratory.
