Brown Treesnake morphological and behavioral differences following ingestion of large meals, 2015

Data set resulting from monitoring the behavior of snakes (n = 62) that had been feed a standardized large meal with transmitter, proportional to their body mass, to make direct comparisons to a control group of snakes that had not been fed a meal (only the transmitter). Transmitters were equipped with a two-position switch that changes pulse rate when the body position of the animal changes more than 10 degrees from the switch's preset orientation. Changes in pulse rate serve as a proxy measurement for snake activity, under the logic that a relatively stationary/sedentary snake would cause the transmitter to tip less frequently that an actively moving/foraging snake would. The experiment took place in the U.S. Geological Survey's Brown Treesnake study enclosure on Northwest Field of Andersen Air Force Base, Guam.
