Amplification of Emerging Viruses in a Bat Colony
Figure 4. Myotis myotis bat maternity roost composition and reproductive success. Age composition of bats composing the M. myotis maternity roost under study are depicted before and after parturition in 2 different sampling years, 2008 and 2010. The y-axis represents the number of individual bats, additionally indicated in individual bars. The brace and asterisks represent statistical significance of the gain in total colony size after parturition in 2010, compared with colony size in 2008. Error bars represent an assumed 10% error margin in counting.
