Model coefficients of five moon variables (moon fraction, moonlight intensity, time since moonrise, time to moonset, and moonlight duration per night). For each variable, two models are presented: one with skylark occurrence per hour (binomial), and another with skylark abundance per hour (Poisson: number of caught skylarks, excluding zeros) as the dependent variables. Colored dots represent means, thin lines show 95% credible intervals (CrIs), and thick lines indicate 80% CrIs. Effects are considered significant when the 95% CrI does not cross the black zero line. See methods section for further details.
