| Summary: | Temperature is a primary driver in defining the ecophysiological activity and performance of ectotherms. Thus, thermal tolerance limits have a profound effect in determining geographic ranges. In regions with extreme cold temperatures, lower thermal limits of species are a key physiological trait for survival. Moreover, thermal niche breadth also plays an important role in allowing organisms to withstand climatic variability and confers species with broader potential to establish in new regions. Here we study the evolution of thermal tolerance limits among Collembola (Arthropoda) and explore how they are affected by the colonization of polar environments. In addition, we test the hypothesis that globally invasive species are more eurythermal than non-invasive ones. Critical thermal limits (CTmin and CTmax), classic measurements of thermal tolerance, were compiled from the literature and complemented with experimental assays for springtail species. Genetic data of the mitochondrial gene cytochrome oxidase ... : # Colonizing polar environments: thermal niche evolution in Collembola ## Description of the Data and file structure * Sp: Species * n\_max: Number of individuals for CTmax * ctmax\_mean: Mean of CTmax * sd\_ctmax: Standard deviation of CTmax * n\_min: Number of individuals for CTmin * ctmin\_mean: Mean of CTmin * sd\_ctmin: Standard deviation of CTmin * ctrange: Range of CT (CTmax + CTmin) * locality: Region of collection * status: If the species is considered invasive or native * reference\_status: Reference of the invasive/native status * reference\_ct: Reference of the CT value * code\_COI: Code of the sequence * source: Website of the sequence * ramping\_rate: Experimental ramp in ºC/minute * acclimation\_temp\_ºC: Acclimation temperature in ºC * acclimation\_time: Acclimation time in hours, weeks or generations (F2) * cat\_acc\_time: Category attributed to acclimation time * arr\_mean\_ctmax: Mean of the acclimation response ratio for CTmax * arr\_mean\_ctmin: Mean of the acclimation response ratio for ... |
