647 worker ant samples from 16 localities in Finland were analyzed using microsatellite markers and a 1200 bp mitochondrial sequence. The data reveals 69 hybrid nests of varying degrees alongside 27 parental-like nests, showing systematic cytonuclear mismatches. It was collected by Jack Beresford to study hybridization between Formica aquilonia and F. polyctena.
Dryad hosts a dataset from a study on cytonuclear incompatibility as a driver of speciation in the herbaceous plant Campanulastrum americanum. The research quantifies postzygotic reproductive isolation in first-generation hybrids, with fitness reductions up to 92%, and links incompatibility strength to chloroplast genetic distance. The data was authored by Karen B. Barnard-Kubow and last updated in June 2020.
Aggregating results from a study analyzing the three-dimensional shape and size of external head surfaces in male and female Nile tilapia (Oreochromis niloticus). It includes data from computational fluid dynamics simulations used to calculate the effect of head morphology on drag force during locomotion. The analysis found that females, which are maternal mouthbrooders, have a 27% larger external head volume than males, resulting in an approximate 15% increase in drag force.
This dataset originates from a specialized low-turbulence wind tunnel built at Stanford University for studying animal and small vehicle flight. It includes experimental data from a facility capable of airspeeds up to 50 m/s, with turbulence intensities adjustable from 0.030% to 45%.
Experimental data investigates the effects of thermal treatment at five temperatures (65, 80, 95, 110, and 125 °C) on defatted soybean flour for wood adhesive applications. The study measures chemical structure, crystalline degree, water-insoluble content, acetaldehyde value, thermal stability, and bonding properties of adhesives. It was authored by Bing-Han Zhang and published in 2020.
Phylogenetic data from a study investigating evolutionary conflict between chloroplast and nuclear genomes in Neotropical Catasetinae orchids. The dataset includes sequence data used to infer phylogenetic relationships and detect outlier associations using PACo and ParaFit methods. It was authored by Oscar Alejandro Pérez-Escobar and published in 2020.
A 2020 study by Robert M. Griffin provides genetic variance estimates for lifespan and aging in Drosophila melanogaster. The analysis uses 80 chromosome substitution lines, with 40 targeting the X chromosome and 40 targeting the major autosomes, to compare additive genetic variation within and between sexes.
Featuring multi-locus DNA sequence data from a phylogenetic study of the Ambystomatidae family of salamanders. The analysis utilized coalescent-based and concordance-based methods to estimate species trees, robustly resolving many clades while identifying regions of unresolved divergence.
41,000 measurements of 3,200 quantities from medicine, nuclear physics, particle physics, and interlaboratory comparisons were analyzed by David C. Bailey in 2020. The dataset studies reported scientific uncertainties, finding outliers and heavy-tailed distributions of uncertainty-normalized differences.
Annual maps of Antarctic ice velocity from 2007 to 2017, produced by the NASA MEaSUREs program. The dataset is assembled by the NSIDC using synthetic aperture radar (SAR) data from multiple international satellite missions and optical imagery from Landsat-8. It provides a multi-year record for tracking ice sheet dynamics.
A dataset from Ossi Lehtikangas, published in 2020, containing results from a proposed Bayesian reconstruction method for electromagnetic flow tomography. The method estimates the vz-component of velocity fields on pipe cross-sections to address limitations of conventional flow meters in asymmetric flows. It tests different asymmetric velocity fields encountered near pipe elbows, solids-in-water flows in inclined pipes, and stratified or multiphase flows.
Data from a study on the invasive whitefly Bemisia tabaci in tropical Colombia tests for genetic divergence in thermal responses. The dataset includes heritable variation in survival and fecundity under temperature stress, with findings indicating rapid adaptation linked to local mean temperature and temperature variation. Phenotypic divergence for survival after a sublethal heat shock was greater than neutral genetic expectations.
Genetic data from populations of the endemic gecko Urocotyledon inexpectata across the Seychelles Islands, used to examine phylogeographic structure. The dataset contains mitochondrial and nuclear gene sequences, revealing at least two highly differentiated lineages with a main split dated to the Miocene/Late Pliocene. It was authored by Sara Rocha and last updated in 2020.
Experimental data characterizes a single photon avalanche diode designed for 1550 nm photon detection. The dataset includes measurements of leakage current, dark count rate, and single photon detection efficiency across temperatures from 210 to 294 K. It was authored by Xiao Meng and published in 2020.
13 Drosophila species were studied to characterize phenotypic plasticity in thermal limits. The dataset provides high-resolution reaction norms for cold tolerance (CTmin) and heat tolerance (CTmax) across a developmental acclimation temperature range of 12.5 to 30°C. It was created by Mads Fristrup Schou and published in 2020 to investigate interspecific variation and associations with species' climatic parameters.
A collection of numerical and experimental results from a study on the combustion characteristics of pyrophoric activated magnesium. The research establishes a surface heat balance equation and compares computational fluid dynamics (CFD) simulations with infrared thermal imaging data. The dataset is associated with the author Hesong Huang and was last updated in June 2020.
Data from a study comparing Symbiodinium algae communities in waters, sediments, and ten coral species between two thermally distinct reef pools in American Samoa. The analysis, conducted by Ross Cunning, used pyrosequencing to examine clades A, C, D, F, and G across different habitat compartments. It reveals distinct assemblages and altered habitat distributions linked to thermal environments.
A 1290 MHz radar wind profiler on the southeastern coast of the Bay of Biscay collected data from 2010 to 2012 for assessing bird migration. The study used thermal imaging and moon watching to verify biological signatures in the radar echoes. It provides qualitative and quantitative migration parameters including flight altitude and migration traffic rates.
Immunosignature data from a study applying ImmunoSignature Technology (IST) to blood donor samples. The IST platform uses a library of over 100,000 chemically-diverse peptides to capture antibody repertoire information. It was used to train and test algorithms for distinguishing seropositivity for Trypanosoma cruzi, hepatitis B, hepatitis C, and West Nile virus.
Comprising results from a Hodge decomposition analysis of wall shear stress vector fields in aortic blood flows. The analysis compares 11 patients with coarctation of the aorta before and after treatment against 10 control patients. The decomposition subdivides the vector field into five components: gradient, co-gradient, and three harmonic fields.
