This result is likely owing to the unbalanced data (more lactating females sampled), small sample size and skewed data owing to a small number of outliers (table 1).\n\n(b) Call type usage\n\nThe results of the GLMM reveal that low-amplitude calls comprise a significantly larger proportion of the call reper- toire for lactating females than for non-lactating whales (table 2 and figure 2).","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/57572"}]}
