Annual procurement plans for the Main Directorate of the State Tax Service in Ukraine's Poltava region, covering 2020. The data lists procedures for procuring goods, works, and services using public funds. It was published on the States site of Ukraine and last updated on 2020-07-10.
Data from a study comparing pre- and post-copulatory investment in nine populations of the dung fly Sepsis punctum across Europe and North America. The dataset supports analysis of a continental reversal in sexual size dimorphism, with European populations showing male-biased size and North American populations showing female-biased size. It includes measurements related to mating behavior, testes size, spermathecal size, and body morphology.
Featuring RNA-seq data from kidney tissue of three Heteromyid rodent species, used to study the genetic basis of water retention. The analysis identified 1,890 differentially expressed genes between arid and mesic species and 323 annotated full-length genic regions. It was authored by Nicholas J. Marra and published in 2020.
Data from J. Stuart F. Barker's 2020 Dryad publication investigates selection at the Esterase-2 locus in Drosophila buzzatii. It includes results from perturbation-reperturbation experiments on 20 replicate cage populations and pre-adult viability estimates from crosses among 12 sequential gel electrophoretic alleles. The experiments test for direct selective effects versus linked loci influences.
Molecular variation data from one mitochondrial and 13 nuclear genes for the endangered Xenopus gilli and Xenopus laevis frog species. The dataset includes genetic samples collected in 1994 and 2013 to examine hybridization and gene flow. It provides evidence on the lack of extensive introgression despite the presence of F1 hybrids.
Dryad hosts genomic evidence from an evolution experiment on Drosophila serrata. The dataset genotypes over 1,400 single nucleotide polymorphisms (SNPs) across 12 experimentally evolved populations. It was authored by Stephen F. Chenoweth to study the interaction between natural and sexual selection.
Data from Pagán et al. characterizes coding and promoter sequence variation in MHC Class II DQA and DQB genes from bottlenose dolphin populations. The study identified 10 alleles each in DQA and DQB coding regions and 6-7 alleles in their promoter regions, revealing positive selection and geographic differences. It provides genetic context for assessing population vulnerability profiles between estuarine and coastal habitats.
Dryad hosts physiological measurements for 215 bird species collected across a 2.6-km altitude gradient in the Peruvian Andes. The data, authored by Gustavo A. Londono and last updated in 2020, was used to test hypotheses about thermoregulatory costs limiting altitude distributions. It includes metrics such as thermal conductance, body temperature, and lower critical temperature.
Delivering genomic data for testing methods to detect recent selective sweeps while controlling for mutation rate variation and background selection. It was created by Christian D. Huber and published in 2020.
Experimental data from free-living pied flycatchers (Ficedula hypoleuca) where brood size was manipulated to study parental and offspring behaviors. The dataset supports analysis of means and variances in provisioning rates, nestling begging intensity, and parental body mass changes. It was collected by David F. Westneat and published in 2020.
Featuring simulation data from an individual-based model investigating the detection of stabilizing selection in natural populations. It was created by Benjamin C. Haller in 2020 to test hypotheses explaining the paradox of stasis. The data supports the model's conclusion that stabilizing selection is difficult to detect empirically after populations adapt to a fitness peak.
32 Indo-Pacific humpback dolphin samples from the Pearl River Estuary, collected between 2003 and 2011, provide data on MHC class II gene expression and sequence polymorphism. The study investigates two specific genes, DQB and DRB, to evaluate the role of balancing selection in this endangered population. Analysis includes metrics like non-synonymous to synonymous substitution rates and tests for trans-species polymorphism.
Dryad hosts transcriptomic variation data from a study on cryptic field cricket species Gryllus rubens and G. texensis. The dataset supports analyses of demographic history, genetic divergence, and signatures of selection, including FST outlier loci. Author Thomas Blankers published the data in 2020 under a CC0 license.
Data from a 2020 study by Njal Rollinson investigates the paradox of stasis in body size evolution. It provides measurements of directional selection on juvenile and adult size, alongside selection against investment per offspring. The dataset supports analysis of trade-offs between fecundity and juvenile size.
Population genetic simulations evaluate seven regression-based model selection methods for landscape genetics. The study assesses method performance across varied landscapes differing in resistance variables, magnitude, and functional relationships. Andrew J. Shirk authored this dataset, which was last updated in June 2020.
Quantitative genetic analysis of leaf traits across wild tomato species (Solanum sect. Lycopersicon) using an introgression line population. The study maps quantitative trait loci (QTL) for traits associated with adaptation to precipitation, with a QTL Sign Test indicating directional natural selection on several traits. Data includes stomatal distribution QTL and genetic correlations with carbon isotope discrimination.
Featuring GPS and video data from peregrine falcons (Falco peregrinus) attacking stationary targets, maneuvering targets, and live prey. The trajectories are modeled using system identification techniques, fitting them to the proportional navigation (PN) guidance law used by guided missiles, with a median navigation constant N < 3.
Comprising simulation results modeling adaptation under divergent selection with gene flow across a set of two-node, two-phenotype genetic network motifs. It was created by Tyler D. Hether and published in 2020 to analyze how network interactions shape mutational (co)variance (M-matrix) and constrain evolutionary trajectories.
Zachariah Gompert produced this simulation dataset in 2020 to test multilocus approaches for measuring selection on correlated genetic loci. It models high-dimensional genomic data where the number of parameters exceeds observations (p ≫ n) to evaluate the efficacy of Bayesian sparse linear mixed models.
Passports of budget programs of the executive committee of the Loshkarivka village council for 2019. The dataset was published on the States site of Ukraine and last updated on July 20, 2020.
