This dataset contains information about the multivariate plastic life-history responses and thermal tolerance capability of 56 Daphnia magna clones exposed to 4 different environments. The experiment was conducted in a laboratory at the University of Liverpool in 2017. The work was part of a larger mesocosm study that aimed to tease apart how plasticity and genetic diversity influence the evolutionary potential of natural populations. Life history data were measured in common garden experiments. For each clone of the same genotype across all environments, we measured: length at maturity; length at second clutch; age at maturity; age at second clutch; juvenile growth rate ((length at maturity - length as neonate) / age at maturity); adult growth rate ((length at second clutch - length at maturity) / (age at second clutch-age at maturity)); average fecundity (across clutches 1 and 2); and average offspring size (across clutches 1 and 2) The work was supported by the Natural Environment Research Council (Grant NE/K007394/1).

This dataset contains phenotypic information for three-spined stickleback (Gasterosteus aculeatus) that were raised from a single marine x freshwater cross from populations on North Uist, Scottish Outer Hebrides for approximately 5 generations in a freshwater pond in Nottinghamshire, UK. The fish were then used in a quantitative trait loci (QTL) experiment to determine the genomic regions associated with various phenotypic traits in the fish. The phenotypic information includes body length, body weight, sex, whether species of the parasite Schistocephalus was observed in the body cavity, and the composition of the body of the fish (determined by ICPMass Spectromotry) including the following elements: B, Na, Mg, P, S, K, Ca, Ti, Li, Be, Al, V , Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Mo, Ag, Cd, Cs, Ba, Tl, Pb, U Full details about this nonGeographicDataset can be found at https://doi.org/10.5285/e7797949-8b96-423e-870e-69e8314dbe90

Data contain measurements of physiological variation in threespine stickleback from Icelandic populations. The data includes metabolic rates measured on individual stickleback fish across three temperatures (Metabolism.csv), inter-individual variation in distances between individuals under different temperature treatments using fish from a geothermal and ambient population (Sociability.csv), and the time individuals spent under different temperatures on their own (TemperaturePreference.csv).

This dataset contains information about hourly temperature variation, phenotypic and genetic change, and change in environmental parameters in a two-year mesocosm study designed to tease apart the impact that phenotypic plasticity and genetic diversity have on rate of adaptation to experimental heatwaves. All data were collected between 2017 and 2019. Thermal data was collected continuously using data loggers. The frequency of natural heatwaves was manipulated using a programmable aquatic mesocosm facility using data collected from real heatwaves from 2006. Phenotypic evolution was tracked using intermittent common garden life-history studies while changes in clone frequency were determined using microsatellite markers to track changes in clone frequency in manipulated populations over two years. Experimental data on zooplankton community dynamics were monitored using intermittent depth integrated sampling of communities in each mesocosm over two years. The work was supported by the Natural Environment Research Council (Grant NE/N016017/1). Full details about this dataset can be found at https://doi.org/10.5285/2ae5e8d3-be36-4517-b80c-c6b91792b769
