Ecosystem vulnerability to invasive and alien species

This service provides a user-friendly Graphical User Interface (GUI) that allow researchers to run a workflow wrapped into R code for:

- the reshaping of the input dataset in order to obtain alien species and native specie richness for each family at the habitat and site level. 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.
