The distribution of native C3 and C4 grasses in a temperate arid region of Mendoza, Argentina, was studied in six areas at different altitudes.

At medium altitudes (1100–1600 m) grass species composition is balanced but plant cover of C3 species is greater. Of 31 genera in the whole area, 19 were C4. Only the genera Stipa (C3) and… CONTINUE READING
