From: Co-roosting relationships are consistent across years in a bat maternity group
Lagged association rates for female little brown myotis with at least 10 day roost observations during the pregnancy period from 2012 to 2021 in Salmonier Nature Park demonstrating the probability that an association persists on the i-th day after it first occurs. Red dashed line denotes the null rate of association calculated based on Whitehead36. Periods of no data that occur at yearly intervals correspond to fall-winter (swarming and hibernation period) and no data were collected in 2020. The inset shows the average number of roosts in use by day of the year (Julian Day) across all years of the study where the line represents the smoothed value based on a smoothed loess fit and the shaded area shows the standard error. Fewer roosts used early in each year may correspond to the increased lagged association rate peaks seen at the start of each maternity period.
