AB - In contrast to documented increases in woody plant dominance of former savannas and grasslands of North America, ecotones between oak (Quercus L.) woodlands and semi‐desert grasslands of the southwestern United States and northwestern Mexico have been relatively stable over the past several centuries. Soil resource partitioning, wherein shallow‐rooted grasses use summer precipitation and deep‐rooted woody plants use winter precipitation, may have contributed to the stable coexistence of grasses and trees that form savannas at this ecotone. Thus, predicted changes in regional precipitation patterns and soil moisture caused by anthropogenic trace gas emissions have the potential to alter interactions between woody plants and grasses with potential ramifications for their relative abundance and distribution.
