Columns indicate response variable, model terms, Akaike's Information Criterion (AIC) score, and difference in AIC score from the best model (ΔAIC). Model terms are abbreviated as follows: DAYL (proportion daylight in each 6 h period), LME (NOAA Large Marine Ecosystem), SEAS (days since 1 October), LUN (lunar fraction in each 6 h period), WIND (NCEP2 interpolated 10 m wind speed).
