TABLE J1. Results of the multi-model inference procedure used to select the best model structure on culmen length of chicks of Black-browed Albatrosses at Kerguelen from 1968 to 2010. The n indicates the number of models used to obtain the sum of AIC weights for a given type of model. Evidence ratios were calculated following Burnham and Anderson (2002). They allow obtaining an idea of the closeness between two types of models.
