In a review about the use of isoscapes for natural resource management in the Brazilian context, which has high biological diversity and landscape heterogeneity, the authors present this figure that shows mean annual precipitation δ¹⁸O (A) and δ²H (B) isoscapes. As this figure presents, the average rates show a significantly lower spatial variation in comparison to temporal and spatial fluctuation found by other studies at a state level. Therefore, developing precipitation isoscape models specific for Brazil is imperative, since current global models mask part of the natural variations of isotopic ratios.
