Limnology of Botos Lake, a tropical crater lake in Costa Rica.

open access: yesRevista 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.
