“…Reduced growth rates as a consequence of inclement weather as found in the present study (Figs 6 & 7) was also described for the building-dwelling Pipistrellus subflavus in the U.S.A. (Hoying & Kunz, 1998) and the foliage-roosting Lasiurus cinereus in Canada (Koehler & Barclay, 2000).…”

The timing of birth and postnatal growth in lesser horseshoe bats Rhinolophus hipposideros were studied during 2000 and 2001 at three maternity roosts located in the provinces of Carinthia and Salzburg, Austria. Postnatal growth curves for length of forearm and body mass were determined separately for the different colonies and years. Cooler weather during June 2001 coincided with a median birth date that was 8 days later than in 2000, whilst the difference between colonies was 4 and 5 days, respectively, for the pooled data of both years. Cool temperatures in June also coincided with a longer duration of the parturition period. Postnatal growth rates were higher than in most other bat species but differences between years and colonies were considerable. These differences may be attributed to the ambient roost temperatures, whereby the young of two cooler roosts showed significantly reduced growth rate during 8 days of cool weather in 2000. Moreover, later born and therefore smaller pups were more strongly affected by low temperatures than earlier born and larger ones. The mean length of forearm of young lesser horseshoe bats at the beginning of September equalled that of adult bats, whilst their body mass was still lower. Non-volant juveniles did not cluster following the nightly emergence of adult females, and a preferred location within the roosts could not be identified. High and very low roost temperatures, however, did have an influence on the location of non-volant young in the colonies.

“…We presume that the roost mates of the juvenile bat we radio-tagged were its mother and sibling, which is consistent with the typical litter size reported in the literature (Constantine 1966, Koehler and Barclay 2000, Perry and Thill 2007, Willis and Brigham 2005. Parturition dates have been observed during mid-June in Arkansas (Perry and Thill 2007), Iowa (McClure 1942), and southern Manitoba, Canada (Koehler and Barclay 2000). In Manitoba, young became volant between 26 and 33 d after birth, but continued to nurse for an additional 16 days, and remained with their mother up to 19 days post-volancy.…”

“…Since bats are heterothermic, their body temperature and physiological activities are also strongly affected by changes in their roost temperature. Several studies have shown a clear correlation between birth time, prevailing climatic temperatures, and the size of juvenile bats, especially horseshoe bats (Rhinolophidae), along the respective species' northern distribution ranges (Ransome 1989(Ransome , 1998McOwat and Andrews 1995;Hoying and Kunz 1998;Koehler and Barclay 2000;Kunz and Hood 2000;Hood et al 2002;Reiter 2004). Sustained foraging flight in bats requires a mature, rigid skeleton (Burnett and Kunz 1982), and their wing bone growth takes place during the first few weeks of life.…”

Growth characteristics of three species of horseshoe bats (Rhinolophus ferrumequinum, R. euryale and R. mehelyi) were studied in northern Bulgaria, and measurements of cohorts born there in different years were compared interannually. Bulgarian horseshoe bats are usually born in the first 3 weeks of June and start to leave the roost at an age of about 3 weeks. Young horseshoe bats of all three species had attained more than 95% of the adult dimensions at the time when they started to regularly leave the cave to forage on their own in mid of July. Individually marked juvenile R. ferrumequinum reached adult dimensions in most external wing measurements in the first half of August. Accordingly the pooled measurements of all juveniles did not differ anymore from those of adult bats in the second half of August. The same pattern was found in R. mehelyi and R. euryale. We found a clear relationship between the climatic conditions prevailing in each year and the final size of individuals born respectively in those years. Whereas previous studies have addressed climatic effects only on several bat species along their northern limits of distribution, these data provide the first evidence for an influence of climate on the growth of individuals in the centre of the species' distributions.
