Figure 4: Seasonal variation in the activity of Myotisbats at “Middle Earth” cave in 2018. Panel (i) shows all Myotisspecies combined, detected as full spectrum sonograms and identified by
automated identification to genus using the Bat Classify software. The
temperature data shown in panel (ii) were obtained from the mouth of the
cave at dusk, and the smoothed seasonal pattern (fitted using a GAM, k =
6), is shown in addition to the raw data. Seasonal activity patterns of
individual taxa are shown in panels (iii) to (vi).
