Finite Mixture Model-based classification of a complex vegetation system
2020
Aim: To propose a Finite Mixture Model (FMM) as an additional approach for classifying large datasets of georeferenced vegetation plots from complex vegetation systems. Study area: The Italian peninsula including the two main islands (Sicily and Sardinia), but excluding the Alps and the Po plain. Methods: We used a database of 5,593 georeferenced plots and 1,586 vascular species of forest vegetation, created in TURBOVEG by storing published and unpublished phytosociological plots collected over the last 30 years. The plots were classified according to species composition and environmental variables using a FMM. Classification results were compared with those obtained by TWINSPAN algorithm. …
Modelling strategies for the reduction of fat dormice in northern Italian hazel groves
2018
The production of hazelnuts represents an important resource for several Italian rural areas. Sicily and Piedmont, two of the most important producers of hazelnuts, are affected by the presence of the dormouse (Glis glis), that has considerably severely harmed the production of hazelnuts. This study aims to analyse the issue in the Province of Cuneo in Piedmont and to evaluate the sustainability of the policies implemented by using the system dynamics (SD) methodology. An SD predator-prey microworld was built to reproduce the main relevant cause and effect relationships between the development of the dormouse population and local hazelnut production. The results of the SD microworld simulat…
