If more that 1 EUNIS habitat is present in a site, the richness will be calculate for the two (or more that 2) habitats in the site; - the selection of the best fitting model, by calling a set of R functions from the packages lme4 and MuMIn. Initially, a full GLMM model is calculated including both richness and level-1 EUNIS habitat as fixed factor. Subsequently, reduced models are calculated and compared with the full model using the Akaike Information Criteria (AIC). The model showing the best AIC is used to create the output (tables and graph); - the plot of the rarefaction curves on the reshaped dataset. modelling climate change alien species EUNIS habitats Generalized Linear Mixed Model R code rarefaction curve 2016 2021 license copyright LifeWatch Italy 2021 University of Bari, Biology Department CNR Electromagnetic Sensing of the Environment (IREA), Remote Sensing Departement CNR - Institute of Ecosystem Study LifeWatch ERIC Service Centre University of Salento, LifeWatch Italy Cataldo Pierri Paolo Tagliolato Paolo Colangelo Maria Teresa Manca Lucia Vaira Alberto Basset
