2023_ Datasets and R source code of "Allometry Bird Mitochondrial Bioenergetics"

METHODOLOGICAL INFORMATION This dataset contains mitochondrial bioenergetic data and enzymatic activities of our studies from two tissues: skeletal and cardiac muscles, of 13 bird species ranging from 15 g to 160 kg. Methodology: mitochondrial isolation, respiration, enzyme assays, measurement of body mass All analyses were performed in R version 4.2.1 (R Core Team 2022), using phylogenetic comparative analyses. ## Description of the Data and file structure "2023_Data_Allometry Bird mitochondrial bioenergetics" The file contains two sheets: one for the skeletal muscle data and the second for the cardiac muscle. For each section you will find: the name of the species studied, the number of individuals, their body mass (in grams), mitochondrial flux measurements (oxygen consumption, ATP synthesis, ROS generation), ratios (RCR, Slope, Mitochondrial efficiency ATP/O...) and enzymatic activity measurements. Missing data correspond to individuals for whom we were unable to collect data (e.g. no heart samples, not enough tissue for analysis...) ## Phylogenetic tree " BirdTree_MCMCglmm " The phylogenetic tree combining the 13 species studied was obtained from the BirdTree.org website (Rubolini et al., 2015).The tree source used was Hackett Sequenced Species: a set of 10 000 trees with 6670 OTUs each (Hackett et al., 2008). We performed 1000 simulations to create the most parsimonious tree. The avian tree was summarized using BEAST (v1.10.4, 2002-2018) to create a target tree usable in nexus format in R version 4.2.1 (R Core Team 2022). The parameters used were: burnin as a number of trees (100), maximum clade credibility tree as target tree type, and common ancestor heights.
