  • The energy cost of activities central to overall fitness in most animals, such as pedestrian locomotion, is traditionally measured in the laboratory and then extrapolated to field conditions for modeling or hypothesis-testing purposes. However, no accurate, direct, in situ validation of these extrapolations has been made on undisturbed animals. We present the first such validation here, on harvester ants (Messor pergandei). After measuring their energy parameters in the laboratory using a… CONTINUE READING
