“…Examination of my preliminary data for a tree-roosting bat suggests that the thermal tolerance of hibernating bats is greater than has been previously appreciated. In tree roosts, daily fluctuations in T skin of C. morio during prolonged torpor bouts typically exceeded the range of T a experienced by cave-roosting bats throughout the entire hibernation season (Hall 1982;Nagel and Nagel 1991;Ransome 1968;Webb et al 1995). Passive daily fluctuations in T skin were of greater amplitude and reached a higher maximum relative to T a in the male bat during winter.…”

“…Body mass losses of M. daubentonii wintering in 100% relative humidity were up to 2.3 times lower than in individuals roosting in 80% relative humidity at the same temperature (Daan, 1973). On the other hand, many vespertilionid species hibernate in crevices (Kuipers and Daan, 1970;Daan, 1973;Bagrowska-Urbańczyk and Urbańczyk, 1983;Bogdanowicz and Urba½czyk, 1983;Lesiński, 1986;Nagel and Nagel, 1991). The ecological meaning of this behaviour is not clear.…”

“…(Kim et al 2009). During hibernation, the temperature preferred by M. formosus was markedly higher than the temperature selected by other cave-dwelling bat species of Korea (Kim 2010), as well as that of most vespertilionid listed by Nagel and Nagel (1991) and by Webb et al (1996). Myotis formosus did not penetrate into cracks (crevices) like pipistrelle or Daubenton's bats (Myotis daubentonii (Kuhl, 1817)) but generally hung from the ceiling or walls, thereby exposing their bodies to air (Kim 2005).…”

Thermal preference and hibernation period of Hodgson’s bats (Myotis formosus) in the temperate zone: how does the phylogenetic origin of a species affect its hibernation strategy?

Hibernation is regarded as a physiological and behavioral adaptation that permits the survival of animals such as bats during seasonal periods of energy shortage. Moreover, the phylogenetic history of a species can be used to investigate the evolution of its thermal regulation system during torpor. Hodgson's bat (Myotis formosus (Hodgson, 1835)) is a temperate species that arose phylogenetically from an Ethiopian lineage, suggesting that this bat lineage secondarily colonized a temperate climate. Therefore, the hibernation pattern of M. formosus may differ from that of other temperate bat species. This study investigated the hibernation period of M. formosus in the temperate climate zone and the relationship between thermal preference and hibernating process of bats. Myotis formosus hibernated in roosts maintained in warm (temperature, 12-14°C) and humid (relative humidity, >95%) ambient conditions. The bats began to hibernate in early October and final arousals occurred in mid-May so that the total length of the hibernation "season" was 220 days. The period of hibernation was strongly influenced by fluctuations in the external minimal temperature. Most bats entered the hibernacula when the external minimal temperature was lower than the temperature of the hibernacula (mean, 13°C) and emerged from the hibernacula when the external temperature exceeded the temperature of the hibernacula. This study suggests that the onset and termination of M. formosus hibernation is due to the interaction between the temperature of the hibernacula and that of the external environment and is based on the thermal preference of the bats. The study also suggests that the hibernation strategy of this species may be a product of its phylogenetic origin as a tropical bat species adapting to a severely cold climate.Résumé : L'hibernation est considérée comme étant une adaptation physiologique et comportementale qui permet à des animaux comme les chauves-souris de survivre durant des périodes saisonnières de pénurie d'énergie. L'histoire phylogénétique d'une espèce peut en outre être utilisée pour étudier l'évolution de son système de thermorégulation durant la léthargie. La chauve-souris d'Hodgson (Myotis formosus (Hodgson, 1835)) est une espèce de chauve-souris des régions tempérées qui provient toutefois, sur le plan phylogénétique, d'une lignée présente en Éthiopie, ce qui suggère une colonisation secondaire de régions tempérées par cette lignée de chauves-souris. De ce fait, les habitudes d'hibernation de M. formosus pourraient être différentes de celles d'autres espèces de chauves-souris des régions tempérées. L'étude se penche sur la période d'hibernation de M. formosus dans la zone climatique tempérée et sur le lien entre la préférence thermique et le processus d'hibernation des chauves-souris. Les M. formosus hibernaient dans des dortoirs dans lesquels des conditions ambiantes chaudes (températures de 12 à 14°C) et humides (humidité relative, >95 %) étaient maintenues. Les chauves-souris ont commencé à hiberner au début d'octobre...
