2 (a) Map of the northern US Rockies with cumulative least-cost paths between systematically placed locations (circles) in spring snow cover cells. Areas in red are predicted to be used more often than those in cooler colors. The color of the circle corresponds to the average cost distance between that location and all other locations, based on modeling. (b) Cumulative plot of the average cost distance (in millions of cost units) between each systematically placed location and all other locations. The graph was divided into four modes (three within the northern US Rockies, and 1 between the Greater Yellowstone Area and Colorado). The yellow mode has the lowest average cost distances (within the Northern US Rockies), the blue bars the next lowest, the pink bars (Crazy and Little Belt Mountains) have the greatest average cost distances in the Northern US Rockies, and the green bars show the distances between all points from Colorado to the Greater Yellowstone Area

In reading this book, you have observed that the spatial data used in landscape ecology
come from many sources and in many forms. For many organisms, these data take
the form of presence or absence at a location, or numbers of individuals at that
same location. For species such as trees, where huge size differences exist between
individuals, indice...
