      abstract     = {This study reports evidence that the timing of leaf growth
                      responds to developmental and environmental constraints in
                      Clusia spp. We monitored diel patterns of leaf growth in the
                      facultative C(3)-crassulacean acid metabolism (CAM) species
                      Clusia minor and in the supposedly obligate CAM species
                      Clusia alata using imaging methods and followed diel
                      patterns of CO2 exchange and acidification. Developing
                      leaves of well-watered C. minor showed a C3-like diel
                      pattern of gas exchange and growth, with maximum relative
                      growth rate (RGR) in the early night period. Growth slowed
                      when water was withheld, accompanied by nocturnal CO2
                      exchange and the diel acid change characteristic of CAM.
                      Maximum leaf RGR shifted from early night to early in the
                      day when water was withheld. In well-watered C. alata,
                      similar changes in the diel pattern of leaf growth occurred
                      with the development of CAM during leaf ontogeny. We
                      hypothesize that the shift in leaf growth cycle that
                      accompanies the switch from C3 photosynthesis to CAM is
                      mainly caused by the primary demand of CAM for substrates
                      for nocturnal CO2 fixation and acid synthesis, thus reducing
                      the availability of carbohydrates for leaf growth at night.
                      Although the shift to leaf growth early in the light is
                      presumably associated with the availability of
                      carbohydrates, source-sink relationships and sustained
                      diurnal acid levels in young leaves of Clusia spp. need
                      further evaluation in relation to growth processes.},
