Primary production of phytoplankton in the three types of Amazonian waters. III. Primary productivity of phytoplankton in a tropical flood-plain lake of Central Amazonia, Lago do Castanho, Amazonas, Brasil

, 1973
The primary productivity of phytoplankton in Lago do Castanho is characterized by a high production density (production per unit volume g C/m³). Because of unfavourable optical conditions in the water body, however, the thickness of the productive area ...

Balance de calor e interacción agua-nutrientes-cadena alimenticia en el lago de Zapotlán, México

, 2007
This paper presents a heat balance for Lake Zapotlán, which was solved numerically using the fourth-order Runge-Kutta method with a step size of one day. Like other tropical lakes, the annual heat budget of Lake Zapotlán is very low.

Nitrógeno: elemento limitante para el crecimiento fitoplanctónico en un lago oligotrófico tropical

, 2008
"El presente estudio tuvo como propósito evaluar si las concentraciones naturales de fósforo y nitrógeno limitaban la biomasa fitoplanctónica en el Lago Alchichica. Se aplicaron tratamientos de enriquecimiento con nitrógeno, fósforoy nitrógeno + fósforo durante las dos etapas características de la hidrodinámica del lago: estratificación y mezcla.Se dio

Metabolismo lacustre de un lago tropical profundo: ¿Fuente o sumidero de carbono?

, 2015
"Los sistemas acuáticos epicontinentales constituyen un componente importante en el ciclo global del carbono. Con el fin de generar una línea base respecto a si los lagos tropicales funcionan como fuente o sumidero de dióxido de carbono (CO2) se evaluó la producción primaria bruta, neta y la respiración en la zona eufótica de un lago oligotrófico ...
