PHOTOSYNTHETIC EFFICIENCY OF PHYTOPLANKTON IN A TROPICAL MOUNTAIN LAKE
Caldasia, 2006 Minimum (F0), maximum (Fm), and variable (Fv = Fm - F0) fluorescence andphotosynthetic efficiency (Fv/Fm) of phytoplankton were measured for severaldepths and under laboratory conditions during two seasons (June and October of2000) in Lake Guatavita, Colombia.

Climate change in lowland Central America during the late deglacial and early Holocene
The transition from arid glacial to moist early Holocene conditions represented a profound change in northern lowland Neotropical climate. Here we report a detailed record of changes in moisture availability during the latter part of this transition (11 ...

Limnology of Botos Lake, a tropical crater lake in Costa Rica.
Revista de biologia tropical, 2001 Botos Lake, located at the Poas Volcano complex (Costa Rica) was sampled eight times from 1994 to 1996 for physicochemical conditions of the water column and phytoplanktonic community composition. Depth was measured at fixed intervals in several transects across the lake to determine its main morphometric characteristics.
