Here is a combined dataset of genetic data on 2,643 individuals from 163 worldwide human populations. These genotypes were all generated on Illumina chips (550, 610, 660) for multiple different studies. The two main papers that this dataset was compiled for are: Hellenthal, et al 2014 A Genetic Atlas of Human Admixture History, Science; and Busby, et al 2015 The role of recent admixture in forming the contemporary West Eurasian genomic landscape, Current Biology. The data are in PLINK format and the BusbyWorldwidePopulations.csv file outlines where the different datasets come from. Note that because these two datasets were combined together, not all populations are typed on the same set of SNPs. We have included genotype data on 523,443 SNPs, of which 441,038 are genotyped on at least 97.5% of individuals. Therefore, additional QC steps are required to filter this set down to high quality calls, depending on the subset of samples that are required. Complete information about the populations used is available in the various publications that are outlined in the associated paper. Note that these same populations are available elsewhere and this dataset represents that compiled for the above mentioned papers. UPDATE 11/11/2019 Thanks to some heroic work by Kristján Helgi Swerford Moore at DECODE, I have now updated the population and sample information to more accurately and verbosely label the individuals.

The purpose of this study was to determine whether using two natural enemies (a predator, Amblyseius swirskii, and parasitic wasp, Eretmocerus eremicus) in combination would be better at suppressing the main pest of poinsettias, the sweetpotato whitefly (Bemisia tabaci), compared to each natural enemy alone. To test whether the combination of the two natural enemies is superior at suppressing the whiteflies compared to each natural enemy alone, we used both a substitutive and additive design (see Sih et al. 1998. Emergent impacts of multiple predators on prey) to test for both intraspecific and interspecific interactions between our natural enemies on whitefly suppression. Experimental design: Experimental units consisted of 12 whitefly-infested potted poinsettias (subsamples) within a large cage (4 ft x 5 ft x 3 ft; w x l x h). Each trial consisted a total of 24 cages split between two adjacent greenhouses (block_greenhouse 8 and 9). Cages were assigned to one of six treatments (4 treatment replications): 1. Control. No natural enemies were released. Only whiteflies at the start of the trial. 2. Eremicus. Twenty-five E. eremicus pupae released into the cage weekly. 3. Swirskii. Two and a half milliliters of A. swirskii bulk (in carrier material, ~123 mites) spread across the 12 poinsettias at weeks 0 and 4. 4. Eremicus + Swirskii. Combination of treatments 2 and 3 above. 5. Eremicusx2. Fifty E. eremicus pupae released into the cage weekly. 6. Swirskiix2. 5 milliliters of A. swirskii bulk (in carrier material, ~246 mites) pread across the 12 poinsettias at weeks 0 and 4. At the start of the trial (week 0), total number of whitefly nymphs, pupae, exuviae, and adults were counted for every other plant within each cage prior to releasing natural enemies. Number of whitefly nymphs, pupae, exuviae, adults, A. swirskii mites, and E. eremicus adults were subsequently counted on the same plants for individual leaves (1 to 10 = lower to upper canopy) for weeks 2, 4, 6 and 8. Due to difference in subsample level (whole plant vs leaf), data is best analyzed if summed to the plant level first, prior to analysis. In our analysis (ob1_analysesv3), we averaged all plants to the cage level prior to analysis to avoid zero-inflation. Entire trial was replicated a total of three times (spring "A", fall "B", and summer). Spring and fall trials are in the same file ("wfcounts"), since initial and environmental conditions were very similar. Summer trial data is found in the "summertrial.csv" file and was ended prematurely (week 6) due to very high whitefly numbers and rapid plant health decline in all treatments. Endeavor (Pymetrozine) insecticide was applied to all treatments on week four in the summer trial, with no apparent suppression to whitefly populations. Hobo data loggers were placed inside cages in the middle of the greenhouse for each trial and recorded temperature (F) and relative humidity in 30-minute intervals.
