Table 2 AIC table of generalized linear models predicting (a) the presence of skin lesions, (b) qPCR detection of Ophidiomyces ophiodiicola, and (c) ophidiomycosis category in snakes from Georgia, USA, 2016–2018 (n = 618). Y = year, M = month, S = species, G = Genus, A = age class, K = number of parameters, AICc = second-order Akaike information criterion, ΔAICc = difference in AICc between ranked models, wi = Akaike weight.
