AbstractThe seasonal pattern of water status of Larrea divaricata was measured on three sites in southern New Mexico. One site had no carbonate deposition layer. One site had a carbonate deposition layer at a depth of 15 cm and the third had carbonate deposition at a depth of 25 cm. Larrea shrubs on sites with no carbonate deposition layer experienced less water stress during periods of greater precipitation. However, plants on sites with carbonate deposition layers showed less water stress when precipitation was low. These differences may in part account for local variations in size, density and pattern of spatial distribution of Larrea.
