Data from: The island-mainland species turnover relationship

Yoel E. Stuart, Jonathan B. Losos & Adam C. Algar
Many oceanic islands are notable for their high endemism, suggesting that islands may promote unique assembly processes. However, mainland assemblages sometimes harbour comparable levels of endemism, suggesting that island biotas may not be as unique as often assumed. Here, we test the uniqueness of island biotic assembly by comparing the rate of species turnover among islands and the mainland, after accounting for distance decay and environmental gradients. We modeled species turnover as a function of...

Data from: Pleiotropy in the wild: the dormancy gene DOG1 exerts cascading control on life-cycles

George C. K. Chiang, Deepak Barua, Emily Dittmar, Elena M. Kramer & Kathleen Donohue
In the wild, organismal life cycles occur within seasonal cycles, so shifts in the timing of developmental transitions can alter the seasonal environment experienced subsequently. Effects of genes that control the timing of prior developmental events can therefore be magnified in the wild because they determine seasonal conditions experienced by subsequent life stages, which can influence subsequent phenotypic expression. We examined such environmentally-induced pleiotropy of developmental-timing genes in a field experiment with Arabidopsis thaliana. When...

Data from: Asexual reproduction in introduced and native populations of the ant Cerapachys biroi

Daniel J. C. Kronauer, Naomi E. Pierce & Laurent Keller
Asexual reproduction is particularly common among introduced species, probably because it helps to overcome the negative effects associated with low population densities during colonization. The ant Cerapachys biroi has been introduced to tropical and subtropical islands around the world since the beginning of the last century. In this species, workers can reproduce via thelytokous parthenogenesis. Here we use genetic markers to reconstruct the history of anthropogenic introductions of C. biroi, and to address the prevalence...

Data from: High gene flow on a continental scale in the polyandrous Kentish Plover Charadrius alexandrinus

Clemens Kuepper, Scott V. Edwards, András Kosztolányi, Monif AlRashidi, Terry Burke, Phillipp Herrmann, Araceli Argüelles Tico, Juan A. Amat, Mohamed Amezian, Afonso Rocha, Hermann Hötker, Anton Ivanov, Joseph Chernicko & Tamas Szekely
Gene flow promotes genetic coherence of species in time and space. It can be modulated by sex-biased dispersal which links population genetics to mating systems. We investigated the phylogeography of the widely distributed Kentish plover Charadrius alexandrinus. This small shorebird has a large breeding range spanning from Western Europe to Japan, and exhibits an unusually flexible mating system with high female breeding dispersal. We analyzed genetic structure and gene flow using a 427 bp fragment...

Data from: A phylogenomic approach to vertebrate phylogeny supports a turtle-archosaur affinity and a possible paraphyletic Lissamphibia

Jonathan J. Fong, Jeremy M. Brown, Matthew K. Fujita & Bastien Boussau
In resolving the vertebrate tree of life, two fundamental questions remain: 1) what is the phylogenetic position of turtles within amniotes, and 2) what are the relationships between the three major lissamphibian (extant amphibian) groups? These relationships have historically been difficult to resolve, with five different hypotheses proposed for turtle placement, and four proposed branching patterns within Lissamphibia. We compiled a large cDNA/EST dataset for vertebrates (75 genes for 129 taxa) to address these outstanding...

Data from: Mate choice and the genetic basis for color variation in a polymorphic dart frog: inferences from a wild pedigree

Corinne L. Richards-Zawacki, Ian J. Wang & Kyle Summers
Understanding how reproductive barriers evolve during speciation remains an important question in evolution. Divergence in mating preferences may be a common first step in this process. The striking colour pattern diversity of strawberry dart frog (Dendrobates pumilio) populations has likely been shaped by sexual selection. Previous laboratory studies have shown that females attend to male coloration and prefer to court with males of their own colour, suggesting that divergent morphs may be reproductively isolated. To...

Data from: Significance Analysis of Prognostic Signatures

Andrew H. Beck, Nicholas W. Knoblauch, Marco M. Hefti, Jennifer Kaplan, Stuart J. Schnitt, Aedin C. Culhane, Markus S. Schroeder, John Quackenbush, Benjamin Haibe-Kains & Thomas Risch
A major goal in translational cancer research is to identify biological signatures driving cancer progression and metastasis. A common technique applied in genomics research is to cluster patients using gene expression data from a candidate prognostic gene set, and if the resulting clusters show statistically significant outcome stratification, to associate the gene set with prognosis, suggesting its biological and clinical importance. Recent work has questioned the validity of this approach by showing in several breast...

Data from: High diversity and widespread occurrence of mitotic spore mats in ectomycorrhizal Pezizales

Rosanne A. Healy, Matthew E. Smith, Gregory M. Bonito, Donald H. Pfister, Gonzalo G. Guevara, Caroline Hobart, Leticia Kumar, Thai Lee, Katherine Stafford, Zai-Wei Ge, Rytas Vilgalys, Gwendolyn Williams, James Trappe, David J. McLaughlin &
Fungal mitospores may function as dispersal units and/ or spermatia and thus play a role in distribution and/or mating of species that produce them. Mitospore production in ectomycorrhizal (EcM) Pezizales is rarely reported, but here we document mitospore production by a high diversity of EcM Pezizales on three continents, in both hemispheres. We sequenced the internal transcribed spacer (ITS) and partial large subunit (LSU) nuclear rDNA from 292 spore mats (visible mitospore clumps) collected in...
