L’ecologia del Picchio Nero, Dryocopus Martius, nelle foreste casentinesi come chiave per la possibile espansione della specie nell'Appennino

Abstract

Ecological mathematical models are useful tools to define geographic distribution and ecological features of species, playing a fundamental role in defining conservation policies. Through the various methods we can use, recently, those which work with only-presence-data are growing in popularity and particularly MaxEnt. The recent colonization of Foreste Casentinesi National Park by Black Woodpecker represent a very interesting study-case to show how this method work, analysing possible evolution of an expansion process that is still evolving.
