We then used an information theoretic approach to compare 13 logistic generalized linear mixed models, each of which related frog occurrence to a distinct combination of additive and interactive ef-fects of fire, vegetation structure and proximity to known breeding sites.Results: For all four species, the effect of one or more fire variables on frog occurrence depended on both the density of breeding sites in the surrounding area, or on the vegetation structure at the trap locality. A classic “fire averse” response of initial de-clines followed by post- fire recovery did occur, but only in frequently burned, low- quality terrestrial habitats (i.e., heath vegetation for Uperoleia tyleri, or locations with few available breeding sites for the remaining species), or in some cases, when suitable habitats were infrequently burned. However, a “fire- dependent” result of negative ef-fects of time since fire was also evident for some species and contexts.Main conclusions: The effect of fire on frog occurrence can be mediated by environ-ment. Therefore, a single species could be identified as either “fire dependent” or “fire averse” depending on the combination of isolation, vegetation types and fire histories in the study region. Failure to account for the context specificity of fire response curves could lead to incomplete conclusions regarding the effect of time since fire—or the cumulative impacts of multiple fires—on faunal assemblages.application/pdfen-AU© 2017 John Wiley & Sons Ltd201810.1111/ddi.126592019-12-01
