This study seeks to determine how temperate bats react to subtropical climates in which flying insects are available throughout the year and in which cave microclimates in winter are appreciably warmer than those typical of temperate climates. The cave temperatures selected by bats in a cold climate are negatively correlated with their body weight; clusters of bats select even colder temperatures. The temperature differential that a bat (or a cluster) maintains with the environment is also a function of body weight (and thus cluster size), rate of metabolism and Qio. Only bats that are both small and nonclustering are capable of hibernating at environmental temperatures above 140C. Therefore, the small Pipistrellus subflavis is the only cave bat that hibernates for an extended period in Florida. Myotis grisescens, a large species, is limited to caves in northernmost Florida, and much of that population migrates northward to winter in Alabama, where the cave temperatures are low enough for large clustering bats to remain in torpor for extended periods. Myotis austroriparius, an intermediatesized species, remains active for the entire year in Florida, although it probably spends more time in torpor in the northern than in the central part of the state. The seasonal pattern of fat deposition in bats is correlated with their hibernal behavior: large fat deposits are found both in M. grisescens and P. subflavus, whereas those in M. austroriparius are larger in northern than in central Florida. Some temperate bats, such as M. grisescens and P. subflavus, do not seem able to eliminate hibernation to take advantage of the nearly continuous food supply in warmer climates. Rather, these species appear to be obligatory hibernators. In these species most of the copulation occurs in fall and winter, which in turn requires that the females remain torpid if pregnancy is to be delayed to spring. In warm climates this behavior is impossible for large or clustering species that require extended periods of torpor. Such species are thus excluded from a subtropical environment.

“…Those studies focused on normal ontogeny in Myotis lucifugus [Kunz and Anthony, 1982], Eptesicus fuscus [Burnett and Kunz, 1982] and Tadarida brasiliensis mexicana [Kunz and Robson, 1995]. The present study assesses ontogeny, both prenatal and postnatal, of two species sharing a common maternity roost environment.Tadarida brasiliensis cynocephala and Myotis austroriparius were the most abundant bat species in Florida, and perhaps in the southeastern USA [Jennings, 1957;Lowery, 1974;Rice, 1957]. The predominant natural roosts used by both species are caves, with M. austroriparius preferentially hanging over pools of water.…”

Skeletogenesis was studied in two species of bats, Myotis austroriparius (southeastern brown bat) and Tadarida brasiliensis (Brazilian free-tailed bat), occupying a maternity roost in central Florida. These bats often use distinct maternity roost environments, so this provided an opportunity to examine differential patterns of long bone growth while fetuses and newborn developed under similar environmental conditions. Some differences in the timing of onset of osteogenesis were revealed in the bats, indicating that some elements of the hindlimb develop relatively more rapidly in T. brasiliensis than in M. austroriparius. Some variance was also noted, with similarity to other species previously studied by others, in the exact timing and elongation of both long bones, as well as carpal and tarsal bones. In contrast to many elements of the long appendicular skeleton of developing Mus musculus, the bats all exhibit relatively precocial patterns of osteogenesis during which cartilaginous precursors are replaced by bone tissue. The relative advanced timing of osteogenesis in select hindlimb bones of T. brasiliensis may account for its relatively low neonatal mortality compared to M. austroriparius newborn in the same roost.

“…This dissociation of reproductive functions and activities has been shown for the species indicated in Table 2. In addition, this dissociation can be inferred from studies of other bats for which more complete data are lacking: Eptesicus fuscus fuscus, western U.S.A. (Phillips, 1966); Myotis austroriparius (Rice, 1957); M. daubentoni (Herlant, 1967); M. keenii septentrionalis (Gustafson, 1975a); M. I. leibii (Gustafson, 1975a); M. mystacinus (Herlant, 1967); Pipistrellus abramus (Nakano, 1928); P. subflavus (Gustafson, 1975a); Plecotus auritus (Courrier, 1927;Stebbings, 1966); P. austriacus (Stebbings, 1966); Rhinolophus ferrumequinum korai (Oh, 1977); Vespertilio superans (Oh, 1977).…”
