Rationale of the case study

  • Rationale of the case study

    The case study was proposed by the LifeWatch CT Mediterranean in order to explore the susceptibility of EUNIS habitat to AS invasions. The case study was originally presented for freshwater and marine habitat (Boggero et al., 2014; Corriero et al, 2016). In the VRE alien species the case study, originally used to analyze freshwater and marine habitat, has been generalized to work with any biodiversity dataset available in the LW data portal. For a full comprehension of the rationale of the case study and the statistical approach used we strongly encourage the users to read carefully Boggero et al. (2014) and Corriero et al. (2016). 


    The workflow allows automating a set of operations that were originally written in an R script. This allows the user not skilled in R to replicate the same analyses in Taverna, and eventually modify the statistical workflow according to the aims of his research. However, for a full comprehension of what are the users doing, knowledge of the statistical tools used in this workflow (Generalized Linear Mixed Model) is a prerequisite. This is particularly relevant for two aspects: understanding if your data are suitable for this kind of analysis (i-e fit the assumption of GLMMs) and for the interpretation of the output.
