Data from: Model selection as a tool for phylogeographic inference: an example from the willow Salix melanopsis

Bryan C. Carstens, Reid S. Brennan, Vivien Chua, Caroline V. Duffie, Michael G. Harvey, Rachel A. Koch, Caleb D. McMahan, Bradley J. Nelson, Catherine E. Newman, Jordan D. Satler, Glenn Seeholzer, Karine Posbic, David C. Tank & Jack Sullivan
Phylogeographic inference has typically relied on analyses of data from one or a few genes to provide estimates of demography and population histories. While much has been learned from these studies, all phylogeographic analysis is conditioned on the data, and thus, inferences derived from data that represent a small sample of the genome are unavoidably tenuous. Here, we demonstrate one approach for moving beyond classic phylogeographic research. We use sequence capture probes and Illumina sequencing...

Data from: The carnivorous plant described as Sarracenia alata contains two cryptic species

Bryan C. Carstens & Jordan D. Satler
Modern methods for species delimitation provide biologists with the power to detect cryptic diversity in nearly any system. To illustrate the application of such methods, we collected data (21 sequence loci) from a carnivorous plant in southeastern North America and applied several recently developed methods (Gaussian clustering, Structurama, BPP, spedeSTEM). The pale pitcher plant Sarracenia alata inhabits the southeastern USA along the northern coast of the Gulf of Mexico. Sarracenia alata populations are separated by...

Data from: Katian (Upper Ordovician) conodonts from Wales

Annalisa Ferretti, Stig M. Bergstrom & Christopher R. Barnes
Middle and Upper Katian conodonts are previously known in the British Isles from relatively small collections obtained from a few localities. The present study is mainly based on 17 samples containing more than 17,000 conodont elements from an approximately 14 m thick succession of the Sholeshook Limestone in a road cut near Whitland, South Wales that yielded a diverse fauna of more than 40 taxa. It is dominated by representatives of Amorphognathus, Aphelognathus/Plectodina, and Eocarniodus...

Data from: Mapping of two suppressors of OVATE (sov) loci in tomato

Esther Van Der Knaap, Gustavo R. Rodriguez & Hyun J. Kim
Tomato fruit shape varies significantly in the cultivated germplasm. To a large extent, this variation can be explained by four genes including OVATE. While most varieties with the OVATE mutation bear elongated fruits, some accessions carry round fruit suggesting the existence of suppressors of OVATE in the germplasm. We developed three intraspecific F_2 populations with parents that carried the OVATE mutation but differed in fruit shape. We used a Bulk Segregant Analysis approach and genotyped...

Data from: Genetic mapping of three quantitative trait loci for soybean aphid resistance in PI 567324

M. A. Rouf Mian, Tae-Hwan Jun & Andy P. Michel
Host-plant resistance is an effective method for controlling soybean aphid (Aphis glycines Matsumura), the most damaging insect pest of soybean (Glycine max (L.) Merr.) in North America. Recently, resistant soybean lines have been discovered and at least four aphid resistance genes (Rag1, Rag2, Rag3 and rag4) have been mapped on different soybean chromosomes. However, the evolution of new soybean aphid biotypes capable of defeating host-plant resistance conferred by most single genes demonstrates the need for...

Data from: A comparison of supermatrix and supertree methods for multilocus phylogenetics using organismal datasets

Daniel A. Janies, Jonathon Studer, Samuel K. Handelman & Gregorio Linchangco
It has been proposed that supertree approaches should be applied to large multilocus sequence datasets to achieve computational tractability. Large datasets such as those derived from phylogenomics studies can be broken into many locus-specific tree searches and the resulting trees can be stitched together via a supertree method. Using simulated data, workers have reported that they can rapidly construct a supertree that is comparable to the results of heuristic tree search on the entire dataset....

Data from: Implementing an evolutionary framework for understanding genetic relationships of phenotypically defined insect biotypes in the invasive soybean aphid (Aphis glycines)

Jacob A. Wenger & Andy P. Michel
Adaptive evolution of pest insects in response to the introduction of resistant cultivars is well documented and commonly results in virulent (i.e. capable of feeding upon resistant cultivars) insect populations being labeled as distinct biotypes. Phenotypically defined, biotypes frequently remain evolutionarily indistinct, resulting in ineffective application of virulence control measures and shorter durability of resistant cultivars. Here we utilize an evolutionary framework to discern the genetic relationship between biotypes of the soybean aphid (Aphis glycines,...
