Description :
The AA. examined the spatial distributions of 30 abundant plant species of the grasslands of North America distributed among 4 functional groups : C4 grasses, C3 grasses, forbs, and woody species. For each species, they mapped its distribution using occurrence data from georeferenced herbarium specimens and a species distribution model (MAXENT). They then assessed which of several climate, soil, and elevation variables contribute to determining its range. Functional groups differ primarily in range size and the centroid of the ranges. Conservation of tallgrass, mixed-grass, and shortgrass prairie biomes will require a flexible strategy with widely distributed habitat over the Great Plains along both north-south and east-west gradients.
