Effect of gender on sap-flux-scaled transpiration in a dominant riparian tree species: Box elder (Acer negundo)

Acer negundo is a dioecious riparian tree species with a spatial segregation of the sexes along soil moisture gradients. Females are typically more common in wet sites along streams (typically F/M = 1.6), whereas males are more common in drier sites away from streams (typically F/M = 0.6). Spatial segregation between sexes may develop because of the higher reproductive cost in females compared to males. Copyright [year] American Geophysical Union.
