Data from: The predictability of genomic changes underlying a recent host shift in Melissa blue butterflies

Samridhi Chaturvedi, Lauren K. Lucas, Chris C. Nice, James A. Fordyce, Matt L. Forister, Zachariah Gompert & Matthew L. Forister
Despite accumulating evidence that evolution can be predictable, studies quantifying the predictability of evolution remain rare. Here, we measured the predictability of genome-wide evolutionary changes associated with a recent host shift in the Melissa blue butterfly (Lycaeides melissa). We asked whether and to what extent genome-wide patterns of evolutionary change in nature could be predicted (1) by comparisons among instances of repeated evolution, and (2) from SNP $\times$ performance associations in a lab experiment. We...

Data from: Distance, elevation, and environment as drivers of diversity and divergence in bumble bees across latitude and altitude

Jason M. Jackson, Meaghan L. Pimsler, Kennan Jeannet Oyen, Jonathan B. Koch-Uhuad, James D. Herndon, James P. Strange, Michael E. Dillon & Jeffrey D. Lozier
Identifying drivers of dispersal limitation and genetic differentiation is a key goal in biogeography. We examine patterns of population connectivity and genetic diversity using Restriction-site Associated DNA sequencing (RADseq) in two bumble bee species, Bombus vosnesenskii and Bombus bifarius across latitude and altitude in mountain ranges from California, Oregon, and Washington, U.S.A. Bombus vosnesenskii, which occurs across a broader elevational range at most latitudes, exhibits little population structure while B. bifarius, which occupies a relatively...

Data from: Phylogenomic insights into the evolution of stinging wasps and the origins of ants and bees

Michael G. Branstetter, Bryan N. Danforth, James P. Pitts, Brant C. Faircloth, Philip S. Ward, Matthew L. Buffington, Michael W. Gates, Robert R. Kula & Seán G. Brady
The stinging wasps (Hymenoptera: Aculeata) are an extremely diverse lineage of hymenopteran insects, encompassing over 70,000 described species and a diversity of life history traits, including ectoparasitism, cleptoparasitism, predation, pollen feeding (bees [Anthophila] and Masarinae) and eusociality (social vespid wasps, ants, and some bees) [1]. The most well-studied lineages of Aculeata are the ants, which are ecologically dominant in most terrestrial ecosystems [2], and the bees, the most important lineage of angiosperm-pollinating insects [3]. Establishing...

Data from: Detection of individual ploidy levels with genotyping-by-sequencing (GBS) analysis

Zachariah Gompert & Karen E. Mock
Ploidy levels sometimes vary among individuals or populations, particularly in plants. When such variation exists, accurate determination of cytotype can inform studies of ecology or trait variation and is required for population genetic analyses. Here we propose and evaluate a statistical approach for distinguishing low-level ploidy variants (e.g., diploids, triploids and tetraploids) based on genotyping-by-sequencing data. The method infers cytotypes based on observed heterozygosity and the ratio of DNA sequences containing different alleles at thousands...

Data from: Vertical differentiation in tropical forest butterflies: a novel mechanism generating insect diversity?

Chris C. Nice, James A. Fordyce, Katherine L. Bell, Matthew L. Forister, Zachariah Gompert & Phil J. DeVries
Many tropical fruit-feeding nymphalid butterflies are associated with either the forest canopy or the understory, however, the exceptions offer insights into the origins of tropical diversity. As it occurs in both habitats of tropical forests in Ecuador and Peru, Archaeoprepona demophon is one such exception. We compared patterns of occurrence of A. demophon in the canopy and understory and population genomic variation for evidence of ecological and genetic differentiation between habitats. We found that butterfly...

Data from: Developmental and evolutionary history affect survival in stressful environments

Gareth R. Hopkins, , Susannah S. French & Edmund D. Brodie
The world is increasingly impacted by a variety of stressors that have the potential to differentially influence life history stages of organisms. Organisms have evolved to cope with some stressors, while with others they have little capacity. It is thus important to understand the effects of both developmental and evolutionary history on survival in stressful environments. We present evidence of the effects of both developmental and evolutionary history on survival of a freshwater vertebrate, the...

Data from: Potential for local adaptation in response to an anthropogenic agent of selection: effects of road deicing salts on amphibian embryonic survival and development

Gareth R. Hopkins, Susannah S. French, & Edmund D. Brodie
The application of millions of tons of road deicing salts every winter in North America presents significant survival challenges to amphibians inhabiting road-side habitats. While much is known of the effects of NaCl on anuran tadpoles, less is known of effects on amphibian eggs, or any caudate life-stage. In addition, little is known of the effects of MgCl2, which is now the 2nd most commonly used road deicer. Most studies have considered amphibians to be...

Data from: Historical contingency in a multigene family facilitates adaptive evolution of toxin resistance

Joel McGlothlin, Megan Kobiela, Chris R. Feldman, Todd A. Castoe, Shana L. Geffeney, Charles T. Hanifin, Gabriela Toledo, Freek J. Vonk, Michael K. Richardson, , Michael Pfrender &
Novel adaptations must originate and function within an already established genome [ 1 ]. As a result, the ability of a species to adapt to new environmental challenges is predicted to be highly contingent on the evolutionary history of its lineage [ 2–6 ]. Despite a growing appreciation of the importance of historical contingency in the adaptive evolution of single proteins [ 7–11 ], we know surprisingly little about its role in shaping complex adaptations...

T. Michael Anderson, Daniel M. Griffith, James B. Grace, Eric M. Lind, Peter B. Adler, Lori A. Biederman, Dana M. Blumenthal, Pedro Daleo, Jennifer Firn, Nicole Hagenah, W. Stanley Harpole, Andrew S. MacDougall, Rebecca L. McCulley, Suzanne M. Prober, Anita C. Risch, Mahesh Sankaran, Martin Schütz, Eric W. Seabloom, Carly J. Stevens, Lauren L. Sullivan, Peter D. Wragg & Elizabeth T. Borer
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant stoichiometry and compare the relative contribution of climatic vs. anthropogenic effects. We addressed this goal by measuring plant elemental (C, N, P and K) responses to eutrophication and vertebrate herbivore exclusion at eighteen sites on six continents. Across sites, climate and...

Data from: Transitions between phases of genomic differentiation during stick-insect speciation

Rüdiger Riesch, Moritz Muschick, Dorothea Lindtke, Romain Villoutreix, Aaron A. Comeault, Timothy E. Farkas, Kay Lucek, Elizabeth Hellen, Víctor Soria-Carrasco, Stuart R. Dennis, Clarissa F. De Carvalho, Rebecca J. Safran, Cristina P. Sandoval, Jeff Feder, Regine Gries, Bernard J. Crespi, Gerhard Gries, Zach Gompert & Patrik Nosil
Speciation can involve a transition from a few genetic loci that are resistant to gene flow to genome-wide differentiation. However, only limited data exist concerning this transition and the factors promoting it. Here, we study phases of speciation using data from >100 populations of 11 species of Timema stick insects. Consistent with early phases of genic speciation, adaptive colour-pattern loci reside in localized genetic regions of accentuated differentiation between populations experiencing gene flow. Transitions to...

Data from: Intraspecific variability and reaction norms of forest understory plant species traits

Julia I. Burton, Steven S. Perakis, Sean C. McKenzie, Caitlin E. Lawrence & Klaus J. Puettmann
1.Trait-based models of ecological communities typically assume intraspecific variation in functional traits is not important, though such variation can change species trait rankings along gradients in resources and environmental conditions, and thus influence community structure and function. 2. We examined the degree of intraspecific relative to interspecific variation, and reaction norms of 11 functional traits for 57 forest understory plant species, including: intrinsic water-use efficiency (iWUE), Δ15N, 5 leaf traits, 2 stem traits and 2...

Dataset for \"Attributes of Phragmites australis in response to climate change using a common garden study\"

Steve Young
The response of plant species to environmental change, including climate, is based on phenotypic plasticity. Empirical research can help in understanding how invasive plants adapt to changing conditions for successful establishment. Our goal was to assess the effect of environment of origin and ecotypic variation on phenotypic response of native and invasive Phragmites australis using morphological and ecophysiological measurements. We established a common garden study using seeds collected from Southwest, Midwest, and Great Lakes regions...

Grand Staircase Escalante Economic Effects Data

Paul Jakus & Sherzod Akhundjanov
The designation of landscape-scale national monuments has generated intense debate as to whether their regional economic effects are positive or negative. National monuments can restrict land uses, thus favoring economic development based on the low-wage tourism industry relative to higher-wage extractive industries. Utah’s Grand Staircase-Escalante National Monument has been managed for landscape-scale conservation whilst protecting existing valid uses. We assess post-designation trends in the ranching, mining, and tourism industries, after which pre- and post-designation paths...

Thirteen years of vegetation chronosequence data in ex-arable and undisturbed fields near Winthrop, Washington, USA

andrew kulmatiski & Karen Beard
Non-native plants have invaded much of the western United States over the past 100 years. Most of these invasive species are early-successional, yet they appear to persist for decades. The goal of this research was to describe non-native and native plant abundance in ex-arable and adjacent undisturbed fields over time.

Genetic differentiation between two species of buckwheat (Eriogonum)

Paul G. Wolf & Jenessa B. Lemon
Discovering the extent of genetic differentiation between closely related taxa facilitates decisions regarding species protection under the Endangered Species Act. Here, we analyze genotype data to explore the relatedness of two buckwheat species: Eriogonum soredium Reveal- a narrow endemic under consideration for protection, and a widespread close relative, Eriogonum shockleyi S. Watson. Eriogonum soredium grows only on Ordovician limestone outcroppings in west central Utah, whereas the range of E. shockleyi is broad, spanning the western...
