... on torpor–arousal cycles of free-ranging little brown bats during hibernation and is one of the first to estimate energy expenditure for a hibernator based on radio-telemetry measurements of T sk . Our measurements of T sk did not support predictions of the torpor optimization hypothesis. We...

.... As the overhelming proportion of animal species are small (<20 g), the new transmitter design greatly expands the range of radio-telemetry applications. The 0.2 g tag can be attached, for example, to a 4 g bird or mammal (transmitter ≤5% of body mass) or to a 2 g insect (transmitter≤10% of body mass; Cant et al...
