Data from: Convergent regulatory evolution and loss of flight in palaeognathous birds

A core question in evolutionary biology is whether convergent phenotypic evolution is driven by convergent molecular changes in proteins or regulatory regions. We combined phylogenomic, developmental, and epigenomic analysis of 11 new genomes of paleognathous birds, including an extinct moa, to show that convergent evolution of regulatory regions, more so than protein-coding genes, is prevalent among developmental pathways associated with independent losses of flight. A Bayesian analysis of 284,001 conserved noncoding elements, 60,665 of which...

Kimball, Andrew L. Mack, Colin M. Miskelly, A. Townsend Peterson … & Brant C. Faircloth
Avian diversification has been influenced by global climate change, plate tectonic movements, and mass extinction events. However, the impact of these factors on the diversification of the hyperdiverse perching birds (passerines) is unclear because family level relationships are unresolved and the timing of splitting events among lineages is uncertain. We analyzed DNA data from 4,060 nuclear loci and 137 passerine families using concatenation and coalescent approaches to infer a comprehensive phylogenetic hypothesis that clarifies relationships...

Data from: Comparative phylogeography of mainland and insular species of Neotropical molossid bats (Molossus)

Livia O. Loureiro, Mark D. Engstrom & Burton K. Lim
Genetic structures, historical events, habitat preferences, and geographic barriers might result in distinct patterns in insular versus mainland populations. Comparison between these two biogeographic systems provides an opportunity to investigate the relative role of isolation in phylogeographic patterns and to elucidate the importance of evolution and demographic history in population structure. Herein we use a genotype by sequencing approach (GBS) to explore population structure within three species of mastiff bats (Molossus molossus, M. coibensis, and...

The Burgess Shale paleocommunity with new insights from Marble Canyon, British Columbia

Karma Nanglu, Jean-Bernard Caron & Robert Gaines
The middle (Wuliuan Stage) Cambrian Burgess Shale is famous for its exceptional preservation of diverse and abundant soft-bodied animals through the “thick” Stephen Formation. However, with the exception of the Walcott Quarry (Fossil Ridge) and the stratigraphically older Tulip Beds (Mount Stephen) which are both in Yoho National Park (British Columbia), quantitative assessments of the Burgess Shale have remained limited. Here we first provide a detailed quantitative overview of the diversity and structure of the...
