Correlative evidence exists suggesting that latitudinal gradients in species diversity are, at least in part, driven by climate, in particular rainfall. Using reciprocal transplantation and drought tolerance studies we examine whether species compositional changes along the Thai-Malay Peninsula are driven by differential species growth and physiological responses to the increasing seasonality of rainfall encountered moving from Malaysia into Peninsular Thailand. To compliment these data, we are also analyzing data from the Center for Tropical Forest Science Forest Dynamics Project plots in Malaysia and Thailand.
