Sedgeley, J. A. 2001. Quality of cavity micro-climate as a factor influencing maternity roost selection by a tree-dwelling bat, Chalinolobus tuberculatus, in New Zealand. Journal of Applied Ecology 38: 425–438.
Building on recent work that showed that long-tailed bats were highly selective of trees and cavities for roosting (Biological Conservation 88:261–276; J. Zoology London 249:437–446), this paper shows that these bats selected cavities on the basis of their thermoregulatory quality. Cavities used conveyed significant thermoregulatory advantages to roost occupants, especially reproductive females during the day and non-volant young, which were left alone for most of the night. Bat roosts had stable microclimates, displaying small ranges in temperature and hu-midity compared with external ambient conditions and available cavities that were not used by bats.
