Between-species differences of behavioural repertoire of castes in the ant genus Pheidole: a methodological artefact?

Abstract

This study highlights the influence of sampling size on the interpretation of between castes division of labour in the dimorphic ant genus Pheidole. We show that data analyses based on rarefaction curves provide better estimates of caste repertoire sizes. Weighted observations of the two worker castes of Pheidole pallidula reveals that the behavioural… (More)
