Abstract

In paleoclimatological reconstruction from lake sediments in Central America, climate and human disturbance signals are difficult to separate. The analysis of diatoms offers paleoclimate records less influenced by human activity. Paper describes the first diatom record a lake sediment core in Costa Rica. Specific study site is Lago de las Morrenas in Chirripó National Park. A single diatom, Aulacoseira lirata/alpigena overwhelmingly dominated all core samples, but whether this reflects long-term stability in lake conditions is uncertain. - (SLD)
