Abstract (englisch):

Most animals undergo ecological niche shifts between distinct life phases,but such shifts can result in adaptive conflicts of phenotypic traits. Metamor-phosis can reduce these conflicts by breaking up trait correlations, allowingeach life phase to independently adapt to its ecological niche. This process iscalled adaptive decoupling. It is, however, yet unknown to what extentadaptive decoupling is realized on a macroevolutionary scale in hemimeta-bolous insects and if the degree of adaptive decoupling is correlated with thestrength of ontogenetic niche shifts. It is also unclear whether the degree ofadaptive decoupling is correlated with phenotypic disparity. Here, we quan-tify nymphal and adult trait correlations in 219 species across the wholephylogeny of earwigs and stoneflies to test whether juvenile and adulttraits are decoupled from each other. We demonstrate that adult head mor-phology is largely driven by nymphal ecology, and that adult head shapedisparity has increased with stronger ontogenetic niche shifts in some stone-fly lineages. Our findings implicate that the hemimetabolan metamorphosisin earwigs and stoneflies does not allow for high degrees of adaptive decou-pling, and that high phenotypic disparity can even be realized when theevolution of distinct life phases is coupled.
