Data from: Development and evaluation of 200 novel SNP assays for population genetic studies of westslope cutthroat trout and genetic identification of related taxa
DNA sequence data were collected and screened for single nucleotide polymorphisms (SNPs) in westslope cutthroat trout (Oncorhynchus clarki lewisi) and also for substitutions that could be used to genetically discriminate rainbow trout (O. mykiss) and cutthroat trout, as well as several cutthroat trout subspecies. In total, 260 expressed sequence tag-derived loci were sequenced and allelic discrimination genotyping assays developed from 217 of the variable sites. Another 50 putative SNPs in westslope cutthroat trout were identified by restriction-site-associated DNA sequencing, and seven of these were developed into assays. Twelve O. mykiss SNP assays that were variable within westslope cutthroat trout and 12 previously published SNP assays were also included in downstream testing. A total of 241 assays were tested on six westslope cutthroat trout populations (N = 32 per population), as well as collections of four other cutthroat trout subspecies and a population of rainbow trout. All assays were evaluated for reliability and deviation from Hardy–Weinberg and linkage equilibria. Poorly performing and duplicate assays were removed from the data set, and the remaining 200 assays were used in tests of population differentiation. The remaining markers easily distinguished the various subspecies tested, as evidenced by mean GST of 0.74. A smaller subset of the markers (N = 86; average GST = 0.40) was useful for distinguishing the six populations of westslope cutthroat trout. This study increases by an order of magnitude the number of genetic markers available for the study of westslope cutthroat trout and closely related taxa and includes many markers in genes (developed from ESTs).
Distinguishing between dispersal and vicariance: A novel approach using anti-tropical taxa across the fish Tree of Life
<p><em>Aim:</em> Anti-tropical taxa are species split by the tropics into disjunct northern and southern populations. These distributions occur throughout the Tree of Life, but the mechanisms proposed to drive this pattern are debated and generally fit into two categories: dispersal and vicariance. Here we quantitatively test the prevalence of dispersal and vicariance as plausible drivers of anti-tropical marine distributions using intra-specific anti-tropical marine fishes as a model system.<br> <em>Location:</em> Primarily Indo-Pacific.<br> <em>Major Taxa Studied:</em> Marine fishes.<br> <em>Methods:</em> To test between dispersal and vicariance in latitudinally disjunct marine fishes, we used an ecological niche modeling framework to predict the spatiotemporal suitability of tropical habitats during contemporary and glacial time periods. Three different model configurations were used per species to test: (1) presence of contemporary tropical suitable habitat for northern populations, (2) the same for southern populations, (3) presence of tropical suitable habitat during the last glacial maximum for the entire species. These models were examined in an evolutionary context to determine if there was any phylogenetic signal in biogeographic predictions. Additionally, we tested if life history traits could account for biogeographic predictions.<br> <em>Results:</em> Our analyses resulted in 87 strongly supported models for 29 anti-tropical fishes across the fish Tree of Life (northern population model, southern population model, and full species model for each taxon). Model projections consistently matched predictions of vicariance in 13 fishes and 10 fishes matched predictions of dispersal regardless of thresholding approach. We failed to find any phylogenetic signal for anti-tropicality in general, or for dispersal and vicariant species specifically. Further, dispersal and vicariant tendencies were not found to be correlated with life history traits. <br> <em>Main conclusions:</em> These data quantitatively support both dispersal and vicariance as active mechanisms driving disjunct distributions in marine systems and suggest that they occur stochastically across the fish Tree of Life. This novel approach for examining dispersal and vicariance hypotheses supports the species-specific nature of biogeographic mechanisms structuring distributions, and that a "one-size-fits-all" prediction for current and future species' responses to environmental change is unlikely to be informative.</p>
