Data from: Challenging the inbreeding hypothesis in a eusocial mammal: population genetics of the naked mole-rat, Heterocephalus glaber.

Colleen M. Ingram, Nicholas J. Troendle, Clare A. Gill, Stanton Braude & Rodney L. Honeycutt
The role of genetic relatedness in the evolution of eusociality has been the topic of much debate, especially when contrasting eusocial insects with vertebrates displaying reproductive altruism. The naked mole-rat, Heterocephalus glaber, was the first described eusocial mammal. Although this discovery was based on an ecological constraints model of eusocial evolution, early genetic studies reported high levels of relatedness in naked mole-rats, providing a compelling argument that low dispersal rates and consanguineous mating (inbreeding as...

Data from: Signal diversification in Oecanthus tree crickets is shaped by energetic, morphometric, and acoustic trade-offs

Laurel B. Symes, Matthew P. Ayres, Colleen P. Cowdery & Robin A. Costello
Physiology, physics, and ecological interactions can generate trade-offs within species, but may also shape divergence among species. We tested whether signal divergence in Oecanthus tree crickets is shaped by acoustic, energetic, and behavioral trade-offs. We found that species with faster pulse rates, produced by opening and closing wings up to twice as many times per second, did not have higher metabolic costs of calling. The relatively constant energetic cost across species is explained by trade-offs...

Data from: Normal table of embryonic development in the four-toed salamander, Hemidactylium scutatum

Carol A. Hurney, Sharon K. Babcock, David R. Shook, Teresa M. Pelletier, Stephen D. Turner, John Maturo, Salimah Cogbill, Michael C. Snow, Kristie Kinch, C.A. Hurney, S.K. Babcock, T.M. Pelletier, M.C. Snow, S.D. Turner & D.R. Shook
We present a complete staging table of normal development for the lungless salamander, Hemidactylium scutatum (Caudata: Plethodontidae). Terrestrial egg clutches from naturally ovipositing females were collected and maintained at 15 °C in the laboratory. Observations, photographs, and time-lapse movies of embryos were taken throughout the 45-day embryonic period. The complete normal table of development for H. scutatum is divided into 28 stages and extends previous analyses of H. scutatum embryonic development (Bishop, 1920; Humphrey, 1928)....

Data from: \"Development of the draft genome sequence of the marbled flounder Pseudopleuronectes yokohamae as a reference of population genomic analysis\" in Genomic Resources Notes accepted 1 February 2015 – 31 March 2015

This article documents the public availability of the draft genome sequence data (raw reads, assembled contigs and unassembled reads) and RAD-tag read data of the marbled flounder Pseudopleuronectes yokohamae (Pleuronectiformes; Pleuronectidae).

Data from: Evolutionary shifts in habitat aridity predict evaporative water loss across squamate reptiles

Christian L. Cox & Robert M. Cox
Aridity is an important determinant of species distributions, shaping both ecological and evolutionary diversity. Lizards and snakes are often abundant in deserts, suggesting a high potential for adaptation or acclimation to arid habitats. However, phylogenetic evidence indicates that squamate diversity in deserts may be more strongly tied to speciation within arid habitats than to convergent evolution following repeated colonization from mesic habitats. To assess the frequency of evolutionary transitions in habitat aridity while simultaneously testing...

Data from: Environmental effects on the structure of the G-matrix

Corlett Wolfe Wood, & Edmund D. Brodie
Genetic correlations between traits determine the multivariate response to selection in the short term, and thereby play a causal role in evolutionary change. While individual studies have documented environmentally induced changes in genetic correlations, the nature and extent of environmental effects on multivariate genetic architecture across species and environments remain largely uncharacterized. We reviewed the literature for estimates of the genetic variance-covariance (G) matrix in multiple environments, and compared differences in G between environments to...

Data from: An examination of fitness costs of glyphosate resistance in the common morning glory, Ipomoea purpurea

Catherine L. Debban, Sara Okum, Kathleen E. Pieper, Ariana Wilson & Regina S. Baucom
Fitness costs are frequently invoked to explain the presence of genetic variation underlying plant defense across many types of damaging agents. Despite the expectation that costs of resistance are prevalent, however, they have been difficult to detect in nature. To examine the potential that resistance confers a fitness cost, we examined the survival and fitness of genetic lines of the common morning glory, Ipomoea purpurea, that diverged in the level of resistance to the herbicide...

Data from: Systems analysis of adaptive responses to MAP Kinase pathway blockade in BRAF mutant melanoma

Brian J. Capaldo, Devin Roller, Mark J. Axelrod, Alex F. Koeppel, Emanuel F. Petricoin, Craig L. Slingluff, Michael J. Weber, Aaron J. Mackey, Daniel Gioeli & Stefan Bekiranov
Fifty percent of cutaneous melanomas are driven by activated BRAFV600E, but tumors treated with RAF inhibitors, even when they respond dramatically, rapidly adapt and develop resistance. Thus, there is a pressing need to identify the major mechanisms of intrinsic and adaptive resistance and develop drug combinations that target these resistance mechanisms. In a combinatorial drug screen on a panel of 12 treatment-naïve BRAFV600E mutant melanoma cell lines of varying levels of resistance to mitogen-activated protein...
