Abstract Analysis of a sediment core from Lago Puerto Arturo, a closed basin lake in
northern Peten, Guatemala, has provided an∼ 8700 cal year record of climate change and …

In the northern tropical Americas (Neotropics), notable hydrological variability has been
documented in multi-proxy paleoclimate records between∼ 600 and 1200 CE. This interval …

Páramo is a grass-or shrub-dominated ecosystem that occupies the cool and wet upper
slopes of tropical mountains, at alpine elevations above the timber or tree line and below the …

Abstract Lakes occur throughout Costa Rica, in a variety of geomorphic settings. Nearly
