Tropical river systems undoubtedly sit at the high end of the global productivity spectrum, and the wet and dry forest catchments they drain have the highest rates of primary production of any terrestrial biome.

Production of epilithophyton in two lakes of the Experimental Lakes Area, northwestern Ontario. 1972. Rivers draining undisturbed tropical catchments are low in nutrients and consequently aquatic primary production is low.

INTRODUCTION Mesoscale features of Gulf Stream circulation have been recognized as important in influencing phytoplankton bio- mass and primary production distributions [e.g., Yentsch, 1987]. They are characterized by climatic conditions that often promote year-round growth, with less seasonal variation in solar irradiance than temperate latitudes. 1982. Sudo, R., H. Ohtake, S.
