Figure Lengend Snippet: Seasonal variation in the activity of Myotis bats at “Middle Earth” cave in 2018. Panel (a) shows all Myotis species combined, detected as full spectrum sonograms and identified by automated identification to genus level using the Bat Classify software. The smoothed seasonal pattern (fitted using a GAM, effective degrees of freedom = 5) is shown in addition to the raw data. The temperature data shown in panel (b) were obtained from the mouth of the cave at dusk, and the smoothed seasonal pattern (fitted using a GAM, effective degrees of freedom = 5) is shown in addition to the raw data. Seasonal activity patterns of individual taxa are shown in panels (c)–(f); the smoothed seasonal pattern for each taxon (fitted using a GAM, effective degrees of freedom = 5) is shown in addition to the raw data. For all graphs, the upper and lower smoothed dotted lines show ±1 SE, respectively. The GAM analyses for these seasonal variations are shown in Tables and .

Article Snippet: Capture data were analyzed using a Chi‐squared approach to test for sex‐ratio differences for each Myotis species within and between years, and using negative binomial GAM models to examine seasonal and between‐year variation in capture rate.

Figure Lengend Snippet: Seasonal variation in the activity of Myotis bats (all species combined) at “Hobbit Hole” cave in 2015–2017, measured as the number of zero crossing files, and identified to genus level by visual inspection of the resulting sonograms. Fitted lines show GAM analysis of activity in each year (Table ). Standard errors not included for the sake of clarity.

Figure Lengend Snippet: Catches of different Myotis species in 2017–2018. Captures are plotted against calendar date, but in each year, the timing of peak activity was different. Solid lines represent model fitted lines from the GAM model for each taxon described in Table (negative binomial error family, log‐link function, maximum k ‐value = 40). Dashed lines represent ±1SE.

Figure Lengend Snippet: Hourly activity of different Myotis species across the night, across the 2018 peak swarming period. The vertical lines indicate the changing night lengths throughout the study period, and the colors indicate respective weeks. (a) Overnight distribution of Myotis nattereri calls. (b) Overnight distribution of Myotis daubentonii calls. Vertical lines and colors represent mean time of sunrise during each week of the study period. Fitted lines show GAM analysis for each week throughout the swarming period (Tables and ). Standard errors are not shown for the sake of clarity.
