Table 1 Competing (ΔQAICc< 2) negative binomial mixed models describing bat activity, as well as null and global models, with random effects for site and transect, by species, at Warm Springs Mountain, Bath County, Virginia, USA, 24 May to 2 August 2015. We present the degrees of freedom (df), log likelihood (logLik), Akaike’s Information Criteria for overdispersion and small sample size (QAICc), delta QAICc (ΔQAICc), and QAICc weight (Weight). *Data for Perimyotis subflavus were not overdispersed, thus estimates are from competing models with ΔAICc < 2

From: Bat activity following repeated prescribed fire in the central Appalachians, USA
