This paper presents the results of a study on the diurnal and seasonal dynamics of photosynthetic parameters in Quercus pubescens leaves under varying water availability and temperature regimes on the southern coast of Crimea. With a sufficient water supply, the diurnal performance of photosynthesis, stomatal conductance and transpiration followed a typical parabolic pattern. On hot days with low-to-moderate drought, however, they exhibited a bimodal pattern with a midday depression. Under sever
