  • 摘要:Species dispersal over the landscape is a dynamical issue. By the way, such biotic process is promoted by a static process, i.e. how much each portion of the landscape pushes species dispersal, and towards which directions. In this view, in this paper I add a further skill to Flow Connectivity, i.e. the potential of calculating and mapping the azimuthal impulses of the landscape to biotic flows. Momentum Flow Connectivity is able to produce landscape maps (both vectorial and raster) of impulse strengths and directions to biotic dispersal. The contribution of this new tool to the conservation of priority species and to the eradication of undesired exotic ones is obvious.
