Nutrient dynamics and phytoplankton resource limitation in a deep tropical mountain lake

Popis výsledku v původním jazyce

Managing lake eutrophication requires a clear understanding of resource limitation of primary productivity, yet historically research on this subject has focused on temperate lakes. In 2010, we quantified several metrics of resource limitation in Lake Atitlan, Guatemala, Central America's deepest tropical mountain lake that has recently experienced extensive phytoplankton blooms. In contrast to many temperate lakes, Lake Atitlan did not show a relationship between total phosphorus (TP) and chlorophyll a(Chl-a) concentrations. Average molar ratios of total nitrogen (TN) to TP decreased from 16.4 to 4.5 between stratified and mixing conditions. During our monitoring period, Tropical Storm Agatha landed on Guatemala, washing in sediment from the watershed, and concentrations of P temporarily increased in the lake by >60%. Initial experimental bioassays indicated phytoplankton growth was colimited by N and P prior to the storm, whereas post-storm assays suggested limitation by P and trace
