A growing number of mammal species are recognized as heterothermic, capable of achieving large energetic savings through the use of torpor. To better understand the conditions in which small mammals use torpor during the summer, we studied Rafinesque's big-eared bats (Corynorhinus rafinesquii) using temperature-sensitive radio telemetry. We found that different hypotheses explaining summer torpor each received strong support from our data in explaining different torpor variables, highlighting the multifaceted nature of torpor and the need to collect large datasets in an ecophysiological context.
