The mimetic butterflies Heliconius erato and H. melpomene have undergone parallel radiations to form a near-identical patchwork of over 20 different wing pattern races across the Neotropics. Previous molecular phylogenetic work on these radiations has suggested that similar but geographically disjunct color patterns arose multiple times independently in each species. The neutral markers used in these studies, however, can move freely across color pattern boundaries and therefore might not represent the history of the adaptive...

Data from: Ecological effects on metabolic scaling amphipod responses to fish predators in freshwater springs

Douglas S. Glazier, Eric M. Butler, Sara A. Lombardi, Travis J. Deptola, Andrew J. Reese & Erin V. Satterthwaite
Metabolic rate is commonly thought to scale with body mass to the 3/4-power as a result of universal body-design constraints. However, recent comparative work has shown that the metabolic scaling slope may vary significantly among species and higher taxa, apparently in response to different lifestyles and ecological conditions, though the precise mechanisms involved are not well understood. To better understand these under-appreciated ecological effects and their causes, it is important to control for extraneous phylogenetic...

Data from: The effects of weak genetic perturbations on the transcriptome of the wing imaginal disc, and its association with wing shape in Drosophila melanogaster

Ian Dworkin, Julie A. Brown Anderson, Youssef Idaghdour, Erin Kennerly Parker, Eric A. Stone, Greg Gibson & Julie A. Anderson
A major objective of genomics is to elucidate the mapping between genotypic and phenotypic space as a step toward understanding how small changes in gene function can lead to elaborate phenotypic changes. One approach that has been utilized is to examine overall patterns of co-variation between phenotypic variables of interest, such as morphology, physiology and behavior, and underlying aspects of gene activity, in particular transcript abundance on a genome wide scale. Numerous studies have demonstrated...

Data from: Epidermal growth factor receptor and transforming growth factor-beta signaling contributes to variation for wing shape in Drosophila melanogaster

Ian Dworkin & Greg Gibson
Wing development in Drosophila is a common model system for the dissection of genetic networks and their roles during development. In particular, the RTK and TGF-beta regulatory networks appear to be involved with numerous aspects of wing development, including patterning, cell determination, growth, proliferation, and survival in the developing imaginal wing disc. However, little is known as to how subtle changes in the function of these genes may contribute to quantitative variation for wing shape,...

Data from: Best practices for justifying fossil calibrations

Smith, Jessica M. Theodor, Rachel C. M. Warnock, Michael J. Benton … & Louis Jacobs
Our ability to correlate biological evolution with climate change, geological evolution, and other historical patterns is essential to understanding the processes that shape biodiversity. Combining data from the fossil record with molecular phylogenetics represents an exciting synthetic approach to this challenge. The first molecular divergence dating analysis (Zuckerkandl and Pauling 1962) was based on a measure of the amino acid differences in the hemoglobin molecule; with replacement rates established (calibrated) using inaccurate paleontological age estimates...

Data from: Quantifying historical trends in the completeness of the fossil record and the contributing factors: an example using Aves

Daniel T. Ksepka & Clint A. Boyd
Improvements in the perceived completeness of the fossil record may be driven both by new discoveries and by reinterpretation of known fossils, but disentangling the relative effects of these processes can be difficult. Here, we propose a new methodology for evaluating historical trends in the perceived completeness of the fossil record, demonstrate its implementation using the freely available software ASCC (version 4.0.0), and present an example using crown-group birds (Aves). Dates of discovery and recognition...
