“…Like some subtropical species, 2002-2003 (N = 136; gray circles), 2003-2004 (N = 114; open squares), and 2007-2008 (N = 87; black triangles) in Hampyeong, Korea. (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).…”

“…ments of the roosts. This is supported by the fact that large hibernating populations are observed in roosts with small entrances (Kim et al 2009). Under stable environments, the bats can spend low energy expenditure for the entire hibernation period, thereby prolonging the hibernation period to 220 days without the additional expense in energy from adjusting the body temperature or moving to more suitable sites.…”

“…The species concentrates to hibernate in caves during winter, but disperses to other habitats such as forests and shrubby areas during summer, and a single specimen or a small colony of less than 10 individuals have been found hanging on leafy trees in Korea (Won 1968;Won and Smith 1999). Since the first record obtained in 1999 of the hibernaculum used by numerous M. formosus individuals in Hampyeong, Jeollanam-do, several hibernacula have been reported elsewhere throughout Korea (Kim et al 2009). …”

“…However, to date little is known about ecological and physiological traits of M. formosus. According to Kim et al (2009), M. formosus has a preference for sites with a warm and narrow temperature range during the winter and that maintain a stable inner environment. These reflect that M. formosus is highly sensitive to temperature conditions in the winter roosting site.…”

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...

The echolocation calls of bats can provide useful information about species that are generally difficult to observe in the field. In many cases characteristics of call structure can be used to identify species and also to obtain information about aspects of the bat's ecology. We describe and compare the echolocation call structure of 14 of the 21 bat spe cies found in Korea, for most of which the ecology and behavior are poorly understood. In total, 1,129 pulses were analyzed from 93 echolocation call sequences of 14 species. Analyzed pulses could be classified into three types according to the pulse shape: FM/CF/FM type, FM type and FM/QCF type. Pulse structures of all species were con sistent with previous studies, although geographic variation may be indicated in some species. Overall classification rate provided by the canonical discriminant analysis was relatively low. Especially in the genera Myotis and Murina, there are large overlaps in spectral and temporal parameters between species. On the other hand, classification rates for the FM/QCF type species were relatively high. The results show that acoustic monitoring could be a powerful tool for assessing bat activity and distribution in Korea, at least for FM/QCF and FM/CF/FM species.
