It seems likely that turbulence under natural conditions, both aquatic and terrestrial, is higher than it is in the bottles or leaf chambers used when photosynthesis is measured experimentally. Most of the maximal photosynthetic rates reported in the literature are probably lower than those which occur in nature.

SummaryIt is now possible to measure, with considerable precision and accuracy, the gas exchange characteristics of plants in natural environments. Controlled experiments can be made in the field on

Photosynthetic activity and respiration in an equatorial African soda lake
SUMMARY. Photosynthetic activity and respiration in Lake Sonachi (Kenya), a meromictic soda lake lying in a volcanic crater, were measured through diel cycles during a 15-month period. A pattern of
Photosynthetic rates of phytoplankton in East African alkaline, saline lakes1
Photosynthetic rates were calculated in six myxophycean-dominated alkaline, saline lakes in Kenya and Tanzania from changes in dissolved O2 in light and dark bottles and from diurnal variations in
Field Measurements of Carbon Dioxide Exchange in Some Woody Perennials
The objectives and problems of making measurements of net carbon dioxide exchange under natural field conditions have been discussed by several investigators, including Tailing (1961), Larcher
Plankton production in Raritan Bay is described based on total chlorophyll data and two series of 24-hr dark and light bottle differential oxygen experiments. Maximum chlorophyll (r) recorded was 663
Pioneering research on C4 photosynthesis: implications for crop water relations and productivity in comparison to C3 cropping systems.
This review summarizes the history of the discoveries of the many anatomical, agronomical and physiological aspects of C 4 photosynthesis and documents the scientists at the University of Arizona and theUniversity of California, Davis, who made these early discoveries.

Energy Fixation and Utilization by Natural Communities in Western Lake Erie
The photosynthesis and respiration rates exhibited by communities concentrated by screening water through No. 25 silk bolting cloth, and by communities studied at their natural population density, are presented below.
    A sample computation from bottle data is as
      This study represents only 2 days' work. On both days the diurnal net rate under completely natural conditions exceeded the rate observed in bottles
      • This finding suggests that diurnal respiration rates may exceed the nocturnal rates
