title: Data, script, full methods and full results for: Macroclimate temperature modulates pH niches of European fen species

description: This package presents data, script, full methods and full results for the paper entitled Macroclimate temperature modulates pH niches of European fen species (under review). The aim of the paper is to model temperature and pH niches at the European scale for 96 fen species in order to test the hypothesis that macroclimate temperature modulates pH niches of the fen species, making the calcicole species the most endangered. The data are presented as working data sheet, i.e., the presence-absence data for 96 tested species in 35,984 vegetaion-plot records supplemented by environmenal variables (GDD5, Minimum temperature of the coldest month, adjusted pH, indication of water table depth). The methods of data preparation, including selection of vegetation-plot data from European Vegetation Archive are described in a separate file. The list of used vegetation-plot databases, their GIVD codes and names of custodians are in separate table (Table 1: Data sources). We further present the R script used for data analysis and detailed results of niche modelling for all tested species.These full results are presented as contour plots representing GAM models of all fen species in relation to pH and climate temperature, with indicated number of samples and occurrence probabilities for individual cells defined as a part of pH temperature gradients. Adjusted r2 and pH ⨯ temperature interaction coefficients are presented. In addition, the GAMs of occurrence probabilities with respect to water table depths estimated by indicator values are presented for all individual fen species.
