- W7712137 abstract "The metapleural gland is a unique and complex structure located on the propodeum of ants. Given its functionin immune defence against microbes, it has undoubtedly played an important role in the ecological success ofants by enforcing colony hygiene and preventing diseases. Although this gland has an important antimicrobialfunction, it has been lost several times. It has been proposed that these losses are due to a shift in nestinghabit, i.e. ants living in trees can afford to loose the metapleural gland because this environment harboursfewer microbes. Here we test this idea, the 'Arboreality Hypothesis', by constructing a phylogeny for 48formicine ant species using eight markers (nuclear and mitochondrial) and Bayesian tree building methods.Character mapping for the presence/absence of the gland and nesting habitat was carried out with SIMMAPincluding 1000 trees from the posterior distribution of the MCMC run. Our results show several independentlosses and regains of the metapleural gland across the subfamily. We also find a significant correlationbetween the two traits, suggesting that the 'Arboreality Hypothesis' can indeed explain the pattern ofpresence/absence of the metapleural gland in this group of ants." @default.
