摘要:Flow connectivity (FC) is a methodology, alternative and in opposition to both circuit theory and least-costmodelling, first introduced in 2013 to realistically forecast biotic flows over real landscapes. FC turns a staticfrictional map into a dynamical simulation of biotic flows from any source points indicated by the user. In thiswork, FC is further developed to find a solution to the problem of detecting the true corridors of speciesdispersals and gene flows. The output of this method is the realistic map of biotic corridors, determined in abottom-up way by considering the interaction between landscape properties and species requirements, and notin a top-down approach based on the supposed expert knowledge of some researcher. Not only true corridorsare mapped, but they are also automatically weighted based on their importance to support biotic flows. Thesame corridor can bear different levels of importance in different portions of its length. This outcome is pivotalfrom both conservation and management viewpoints. An applicative example is provided.
