Data from: A population genetic signature of human releases in an invasive ladybeetle

Yukie Kajita, Eric M. O'Neill, Yanbing Zheng, John J. Obrycki & David W. Weisrock
Biological invasions have been accelerated by a variety of human activities. Propagule pressure, the number of introduced individuals and independent introductions, is likely to be influenced by these human activities and may be an important factor for successful range expansion in new environments. We tested whether the current distribution of the predatory ladybeetle Coccinella septempunctata in the introduced range (USA) is the result of multiple historical human introductions or natural range expansion from the first...

Data from: Concordance analysis in mitogenomic phylogenetics

David W. Weisrock
Here I advocate the utility of Bayesian concordance analysis as a mechanism for exploring the magnitude and source of phylogenetic signal in concatenated mitogenomic phylogenetic studies. While typically applied to the study of independently evolving gene trees, Bayesian concordance analysis can also be applied to linked, but individually analyzed, gene regions using a prior probability that reflects the expectation of similar phylogenetic reconstructions. For true branches in the mitogenomic tree, concordance factors should represent the...

Data from: Parallel tagged amplicon sequencing reveals major lineages and phylogenetic structure in the North American tiger salamander (Ambystoma tigrinum) species complex

Eric M. O'Neill, Rachel Schwartz, C. Thomas Bullock, Joshua S. Williams, H. B. Shaffer, X. Aguilar-Miguel, Gabriela Parra-Olea & David W. Weisrock
Modern analytical methods for population genetics and phylogenetics are expected to provide more accurate results when data from multiple genome-wide loci are analyzed. We present the results of an initial application of parallel tagged sequencing (PTS) on a next generation platform to sequence thousands of barcoded PCR amplicons generated from 95 nuclear loci and 93 individuals sampled across the range of the tiger salamander (Ambystoma tigrinum) species complex. To manage the bioinformatic processing of this...

Data from: Widespread and persistent invasions of terrestrial habitats coincident with larval feeding behavior transitions during snail-killing fly evolution (Diptera: Sciomyzidae)

Eric G. Chapman, Andrey A. Przhiboro, James D. Harwood, Benjamin A. Foote & Walter R. Hoeh
Background: Transitions in habitats and feeding behaviors were fundamental to the diversification of life on Earth. There is ongoing debate regarding the typical directionality of transitions between aquatic and terrestrial habitats and the mechanisms responsible for the preponderance of terrestrial to aquatic transitions. Snail-killing flies (Diptera: Sciomyzidae) represent an excellent model system to study such transitions because their larvae display a range of feeding behaviors, being predators, parasitoids or saprophages of a variety of mollusks...

Data from: Cast adrift on an island: introduced populations experience an altered balance between selection and drift

Eric M. O'Neill, Karen H. Beard & Michael E. Pfrender
A long-standing question in evolutionary biology is what becomes of adaptive traits when a species expands its range into novel environments. Here we report the results of a study on an adaptive colour pattern polymorphism (stripes) of the coqui frog following its introduction to Hawaii from Puerto Rico. We compared population differentiation (φ'ST and FST) for the stripes locus —which underlies this colour pattern polymorphism— with neutral microsatellite loci to test for a signature of...
