Nitrogen is unlikely to consistently limit primary productivity in most tropical lakes
Ecosphere, 2023 Despite mounting evidence that tropical lakes may experience an array of phytoplankton nutrient limitation regimes, references to low‐latitude lakes being predominantly nitrogen limited remain common in the literature. To assess the current understanding

Trophic State: A Useful Scale for Classifying Lakes Based on Biological Productivity
EDISLakes are diverse and come in all shapes and sizes. The Trophic State Classification System allows people to group waterbodies into one of four categories, called “trophic states,” based on their level of biological productivity.

WHO NEEDS TROPHIC STATE INDICES? [PDF]
Lake and Reservoir Management, 1984 ABSTRACT The degree of nutrient enrichment has classically indicated trophic state. Nutrients alone, however, inadequately describe a lake's trophic-dynamic structure. Therefore, trophic state indices are simplifications of a more dynamic process. The specific utility of trophic state indices for their intended uses (classification and ranking by ...
