Punctuational ecological changes rather than global factors drive species diversification and the evolution of wing phenotypes in Morpho butterflies
<p>Assessing the relative importance of geographical and ecological drivers of evolution is paramount to understand the diversification of species and traits at the macroevolutionary scale. Here, we use an integrative approach, combining phylogenetics, biogeography, ecology, and quantified phenotypes to investigate the drivers of both species and phenotypic diversification of the iconic Neotropical butterfly genus <i>Morpho</i>. We generated a time-calibrated phylogeny for all known species and inferred historical biogeography. We fitted models of time-dependent (accounting for rate heterogeneity across the phylogeny) and paleoenvironment-dependent diversification (accounting for global effect on the phylogeny). We used geometric morphometrics to assess variation of wing size and shape across the tree, and investigated their dynamics of evolution. We found that the diversification of <i>Morpho</i> is best explained when considering variable diversification rates across the tree, possibly associated with lineages occupying different microhabitat conditions. First, a shift from understory to canopy was characterized by an increased speciation rate partially coupled with an increasing rate of wing shape evolution. Second, the occupation of dense bamboo thickets accompanying a major host-plant shift from dicotyledons towards monocotyledons was associated with a simultaneous diversification rate shift and an evolutionary "jump" of wing size. Our study points to a diversification pattern driven by punctuational ecological changes instead of a global driver or biogeographic history.</p>

Data from: Post-fledging behavioral ecology of migratory songbirds: How do fledgling activity rates vary across species?
<p>This datsaset contains data for a comparison of fledgling activity rates from 9 songbird species in east-central Illinois, USA, described in the paper: "Jones, TM, and MP Ward. 2021. Post-fledging behavioral ecology of migratory songbirds: how do fledgling activity rates vary across species?"; published in <em>Behavioral Ecology</em>. The dataset contains estimates of fledgling activity rates during the daytime, nighttime, and across the post-fledging period, which were compared to estimates of fledgling morphologies (e.g. mass, tarsus, wing development) and post-fledging survival. Analyses, which can be reproduced with this data, showed that overall rates of post-fledging activity differed by species, but species showed similarities in the development of activity rates across the period. All species exhibited a stead increase in activity rates with age and general patterns mirrored rates of post-fledging mortality, including the presence and absence of post-fledging bottlenecks within each species. Additionally, our findings suggest that fledgling wing development and brood size at fledging contribute to variatio in activity rates within and across species.</p>
