Paper Abstract

Rapid frame rate motion picture data is being used in two diverse areas of biological investigation. A study of the bat population decline at Carlsbad Cavern, New Mexico, requires frequent estimates of the size of the bat population. Motion pictures are taken at intervals during an exit flight and are used to estimate the number of bats leaving the cavern on a given evening. Rapid frame rate motion pictures are also used to analyze the locomotion mechanisms in different species of bats. Electrodes implanted in muscles permit simultaneous recording on motion picture film the movements of a bat and the concurrent electrical activity of a contributory muscle. To permit visualization of skeletal movements during flight, steel wires are firmly implanted in bones and pectoral girdle and exteriorized. Reflective paint applied to the tips of the wires increase their visibility in rapid frame rate motion pictures taken of the bat in flight.
