Data from a study probing the thixotropic and rheopectic behavior of single permeabilized muscle fibers using sinusoidal length changes. The dataset contains measurements of force response and stiffness under varying oscillation frequencies and chemical treatments with EDTA and blebbistatin. It was generated by David Altman and published in 2020.
Encompassing in vivo single unit recordings from the hippocampal CA1 region of freely moving rats. The data was collected to study how environmental enrichment impacts fine spike timing and place-modulated rate coding in a model of cortical malformations. The dataset was authored by Amanda E. Hernan and last updated in June 2020.
Aggregating experimental data from 20 healthy young subjects walking in a virtual reality environment with visual disturbances to induce perceived falls. It includes measurements of muscular responses, ground reaction forces, and body kinematics to study corrective motor responses. The research investigates neural feedback mechanisms with onset times ranging from 350 to 600ms during the gait cycle.
Aggregating neural recordings from the motor cortex of Macaca mulatta monkeys during reaching tasks. It examines preparatory neural events when movements are initiated after an imposed delay, at a self-chosen time, or reactively with low latency. The data supports the hypothesis that a preparatory state is consistently achieved before movement onset.
A 2020 study by Tim R. Hofmeester analyzes data from 20 forest plots across the Netherlands. It measures predator activity, rodent density, tick burdens, and densities of questing and infected nymphs for three pathogens to investigate cascading effects on disease risk.
Presenting quantitative trait locus (QTL) mapping results from a Round-robin cross between twelve diverse S. cerevisiae strains. It identifies genetic variants underlying phenotypic differences related to MAPK signaling cascades and interconnected pathways. The data was generated by Sebastian Treusch and published in 2020.
Experimental results from the first study to analyze the backward homing navigation of Cataglyphis fortis desert ants. It compares their performance in channel and open field experiments to forward-walking control groups, evaluating direction and distance gauging. The data includes observations of foodless search loops performed by the ants.
A study of synonymous genetic variation across genes in natural Escherichia coli isolates and a long-term evolution experiment. The analysis reveals a more than 20-fold variation in synonymous differences among genes in natural isolates. It finds that gene length, not natural variation patterns, predicts synonymous substitution prevalence in the experimental populations.
Next-generation genotype-by-sequencing data tests for genetic introgression between wild and selectively bred Sydney rock oysters from two sites in the Georges River, NSW. The study found strong genetic partitioning and no evidence of gene flow, despite farmed oysters being present since the early 1990s. It also reports higher genetic diversity and heterozygosity in the selectively bred population compared to the wild population.
Over 4,600 opportunistic occurrence records of Enallagma damselflies in the United States, compiled by Jason T. Bried in 2020. The data was used to investigate geographic patterns of species composition and turnover across spatial and phylogenetic scales. It includes validation against systematic presence/absence surveys.
This dataset contains genetic mapping data from a QTL study focused on chromosome five in maize and its wild progenitor, teosinte. The research identified multiple linked QTL of small effect influencing domestication traits, with the smallest QTL support interval containing 54 candidate genes. The analysis used simulated trait data to evaluate mapping power, finding the population design can detect approximately 4.5 QTL per trait even with many underlying causal genes.
Three studies by Elise M. Cardinale, last updated in 2020, investigate the impact of psychopathic traits on moral judgments. The data examines distinctions between judgments about causing emotional distress (fear) and causing physical harm.
Experimental data characterizes lotus fibers extracted using microwave irradiation and hydrogen peroxide treatment. The dataset includes measurements of cellulose content, whiteness, moisture regain, impurity removal rate, fineness, tensile strength, and breaking elongation. It was authored by Cheng Cheng and published in 2020.
Dryad hosts this dataset from a quantitative trait loci (QTL) mapping study of reciprocal F2 hybrids between two strongly differentiated populations of the copepod Tigriopus californicus. The study used a saturated linkage map spanning all 12 autosomes and the mitochondrion to investigate genetic incompatibilities, finding the strongest deleterious interaction was mito-nuclear. Research by Brad R. Foley found viability problems were stronger in males and that trigenic interactions were substantially more frequent than digenic ones in this highly divergent cross.
Behavioral data from a study on post-conflict third-party affiliation in rooks (Corvus frugilegus) and jackdaws (Corvus monedula). The dataset contains observations of aggression and affiliative interactions following conflicts, authored by Corina J. Logan and published in 2020. It tests the hypothesis that affiliation with bystanders reduces further aggression for aggressors.
Biomechanical data from an experiment on male clasping ability and female elytral morphology in two diving beetle species, Dytiscus lapponicus and Graphoderus zonatus. The dataset supports analysis of sexually antagonistic coevolution by comparing adhesive forces on rough versus smooth female morph surfaces. It was authored by Kristina Karlsson Green and published in 2020.
Multilocus genetic sequences and species distribution model projections for the crested newt (Triturus cristatus) were compiled by Ben Wielstra in 2020. The data includes five genetic markers—one mitochondrial gene, three nuclear introns, and one MHC gene—paired with climate layers from the Last Glacial Maximum. This collection supports research into the postglacial recolonization of temperate Eurasia from the Carpathian Mountains.
A large sample of wild sea lions reveals spatial memory deficits predicted by the extent of right dorsal hippocampal lesions from natural domoic acid exposure. The data connects toxin exposure to disrupted hippocampal-thalamic brain networks in Zalophus californianus. This behavioral and neurological dataset provides evidence for how algal toxins may affect survival in wild marine mammals.
Nine delayed-estimation experiments provide data on encoding precision in human visual working memory. The dataset supports a normative theory analyzing set size effects and probing probability. It was authored by Ronald Van den Berg and last updated in June 2020.
The dataset contains molecular and fossil data from terrestrial and marine organisms, used to analyze the timing of the Isthmus of Panama's emergence. It supports an earlier and more complex formation timeline than commonly assumed, with implications for biodiversity and climate models. The data was authored by Christine D. Bacon and last updated in June 2020.
