Zenodo. http://doi.org/10.5281/zenodo.3555223 ----------------------------- The data is composed of two datasets: ----------------------------------------- - Biodiversity_ecosystem_function_data.csv - Cell_traits_data.csv Composition of the Biodiversity ecosystem function dataset ------------------------------------------------------------ The dataset contains 27 columns - Temperature: the temperature treatment, either 15, 25or 30°C - R: the community richness (1, 2, 4, 8 or 16 species) - log2_R: the log2-scaled richness - M: the community identity (e.g. ABCD is a community composed of 4 species, species A, B, C and D) - P: the partition id (5 independent partitions of the species pool were drawn, following Bell et al 2009) - Q: the partitioned species pool id (following Bell et al 2009) - R: the replicate id (3 replicates per community within a partition, named 1 to 3) - SA to SP: the species presence-absence status for each of the 16 species (species A to species P), with 1: species present within the community, 0: species absent - Abundance: number of cells per ml at the end of the experiment - ln_Abundance: log-transformed Abundance - Chl_a : chlorophyll a content at the end of the experiment in pg ml-1 - ln_Chl_a : log-transformed chlorophyll a Composition of the Cell traits dataset ----------------------------------------- The dataset contains 9 columns - Species_alpha: the alphanumeric id of the species used in the Biodiversity ecosystem function dataset - Species_name: species identity - Phylum: the phylum - ln.c: the ln transformed metabolic rate b(Tc) at the reference temperature Tc = 293.15°K from the Sharpe-Schoolfield equation (eq. 4 in the article) in µgO2 cell-1 hour-1 - Ea: the activation energy (eV) from the Sharpe-Schoolfield equation - Eh: the deactivation energy (eV) from the Sharpe-Schoolfield equation - Th: the temperature at which half of the enzyme have become non functional (°K) from the Scharpe-Schoolfield equation - Topt: the optimum temperature from differentiating the Sharpe-Schoolfield equation. It is presented in °C to be easier to link to the temperature treatments in the experiment - cell_volume: the cell volume, in µm
