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: 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...

Data from: Evolutionary history of a complex adaptation: tetrodotoxin resistance in salamanders

Charles T. Hanifin & William F. Gilly
Understanding the processes that generate novel adaptive phenotypes is central to evolutionary biology. We used comparative analyses to reveal the history of tetrodotoxin (TTX) resistance in TTX-bearing salamanders. Resistance to TTX is a critical component of the ability to use TTX defensively but the origin of the TTX-bearing phenotype is unclear. Skeletal muscle of TTX-bearing salamanders (modern newts, family: Salamandridae) is unaffected by TTX at doses far in excess of those that block action potentials...

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: Carrion fly-derived DNA metabarcoding is an effective tool for mammal surveys: evidence from a known tropical mammal community

Torrey W. Rodgers, Charles C. Y. Xu, Jacalyn Giacalone, Karen M. Kapheim, Kristin Saltonstall, Marta Vargas, Douglas W. Yu, Panu Somervuo, W. Owen McMillan & Patrick A. Jansen
Metabarcoding of vertebrate DNA derived from carrion flies has been proposed as a promising tool for biodiversity monitoring. To evaluate its efficacy, we conducted metabarcoding surveys of carrion flies on Barro Colorado Island (BCI), Panama, which has a well-known mammal community, and compared our results against diurnal transect counts and camera-trapping. We collected 1084 flies in 29 sampling days, conducted metabarcoding with mammal-specific (16S) and vertebrate-specific (12S) primers, and sequenced amplicons on Illumina MiSeq. For...

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: The scaling of population persistence with carrying capacity does not asymptote in populations of a fish experiencing extreme climate variability

Richard S.A. White, Brendan A. Wintle, Peter A. McHugh, Douglas J. Booker, Angus R. McIntosh & Richard S. A. White
Despite growing concerns regarding increasing frequency of extreme climate events and declining population sizes, the influence of environmental stochasticity on the relationship between population carrying capacity and time-to-extinction has received little empirical attention. While time-to-extinction increases exponentially with carrying capacity in constant environments, theoretical models suggest increasing environmental stochasticity causes asymptotic scaling, thus making minimum viable carrying capacity vastly uncertain in variable environments. Using empirical estimates of environmental stochasticity in fish metapopulations, we showed that...

Data from: Long-term balancing selection on chromosomal variants associated with crypsis in a stick insect

Dorothea Lindtke, Kay Lucek, Victor Soria-Carrasco, Romain Villoutreix, Timothy E. Farkas, Rüdiger Riesch, Stuart R. Dennis, Zach Gompert & Patrik Nosil
How polymorphisms are maintained within populations over long periods of time remains debated, because genetic drift and various forms of selection are expected to reduce variation. Here, we study the genetic architecture and maintenance of phenotypic morphs that confer crypsis in Timema cristinae stick insects, combining phenotypic information and genotyping-by-sequencing data from 1360 samples across 21 populations. We find two highly divergent chromosomal variants that span megabases of sequence and are associated with color polymorphism....

Data from: Competition between apex predators? Brown bears decrease wolf kill rate on two continents

Trophic interactions are a fundamental topic in ecology, but we know little about how competition between apex predators affects predation, the mechanism driving top-down forcing in ecosystems. We used long-term datasets from Scandinavia (Europe) and Yellowstone National Park (North America) to evaluate how grey wolf (Canis lupus) kill rate was affected by a sympatric apex predator, the brown bear (Ursus arctos). We used kill interval (i.e. the number of days between consecutive ungulate kills) as...

Data from: Stable isotope tracers reveal a trade-off between reproduction and immunity in a reptile with competing needs

Andrew M. Durso & Susannah S. French
1.Trade-offs between the reproductive and immune systems are predicted when resources are limited, but are difficult to measure. 2.We used 15N labeled amino acids to directly compare protein allocation by lizards to eggs and healing wounds. 3.We showed that these two demands compete for the same resource, and that the ratio of protein allocation between them was related to body size, reproductive stage, and plasma corticosterone levels. 4.On average, rates of leucine deposition into eggs...
