Data from: Limitations of climate data for inferring species boundaries: insights from speckled rattlesnakes

Jesse M. Meik, Jeffrey W. Streicher, A. Michelle Lawing, Oscar Flores-Villela & Matthew K. Fujita
Phenotypes, DNA, and measures of ecological differences are widely used in species delimitation. Although rarely defined in such studies, ecological divergence is almost always approximated using multivariate climatic data associated with sets of specimens (i.e., the “climatic niche”); the justification for this approach is that species-specific climatic envelopes act as surrogates for physiological tolerances. Using identical statistical procedures, we evaluated the usefulness and validity of the climate-as-proxy assumption by comparing performance of genetic (nDNA SNPs...

Data from: Multilocus phylogeography reveals nested endemism in a gecko across the monsoonal tropics of Australia

Multilocus phylogeography can uncover taxonomically unrecognized lineage diversity across complex biomes. The Australian monsoonal tropics includes vast, ecologically intact savanna-woodland plains interspersed with ancient sandstone uplands. Though recognized in general for its high species richness and endemism, the biodiversity of the region remains underexplored due to its remoteness. This is despite a high rate of ongoing species discovery, especially in wetter regions and for rock-restricted taxa. To provide a baseline for ongoing comparative analyses, we...

Data from: Estimating the temporal and spatial extent of gene flow among sympatric lizard populations (genus Sceloporus) in the southern Mexican highlands

Jared A. Grummer, Martha L. Calderón-Espinosa, Adrián Nieto-Montes De Oca, Eric N. Smith, Fausto R. Méndez De La Cruz & Adam D. Leaché
Interspecific gene flow is pervasive throughout the tree of life. Although detecting gene flow between populations has been facilitated by new analytical approaches, determining the timing and geography of hybridization has remained difficult, particularly for historical gene flow. A geographically explicit phylogenetic approach is needed to determine the overlap of ancestral populations. In this study, we performed population genetic analyses, species delimitation, simulations and a recently developed approach of species tree diffusion to infer the...

Data from: Whole transcriptome analysis reveals changes in expression of immune related genes during and after bleaching in a reef-building coral

Jorge H. Pinzón, Bishoy Kamel, Colleen A. Burge, C. Drew Harvell, Mónica Medina, Ernesto Weil & Laura D. Mydlarz
Climate change is negatively affecting the stability of natural ecosystems, especially coral reefs. The dissociation of the symbiosis between reef-building corals and their algal symbiont, or coral bleaching, has been linked to increased sea surface temperatures. Coral bleaching has significant impacts on corals, including an increase in disease outbreaks that can permanently change the entire reef ecosystem. Yet, little is known about the impacts of coral bleaching on the coral immune system. In this study,...

Data from: EpiRADseq: scalable analysis of genome-wide patterns of methylation using next-generation sequencing

Drew R. Schield, Matthew R. Walsh, Daren C. Card, Audra L. Andrew, Richard H. Adams & Todd A. Castoe
1. Research addressing the role of epigenetics in a diversity of experimental and natural systems is rapidly accumulating. Diverse methods have been developed to study epigenetic states, including bisulfite sequencing and AFLP-based approaches. However, existing methods are sometimes difficult to apply to non-traditional model organisms that lack genomic resources (bisulfite sequencing), and can fail to be economical and readily scalable to diverse research questions because of reliance on traditional Sanger sequencing (AFLP approaches). 2. Here...
