Table 3 Akaike Information Criterion values for each candidate model for the probability of seedling survival in 2013 and in 2014 following burn treatments applied to longleaf pine seedlings in South Carolina, USA, in 2013. Lower AICc values and higher wi values indicate better models for the data, and the best model for each year is shown in boldface; RCD = root collar diameter, Max = peak temperature during burn application; Area60 = area above 60 °C within the time−temperature curve; Dur60 = duration (s) with temperature above 60 °C; Month = month of treatment application (January or May)
