Leaf Area Index (LAI) has been defined as the total leaf area (one-sided) in relation to the ground. LAI has an impact on tree growth and recruitment through the interception of light, which in turn a...
Turrialba Volcano, located in Central-Southern Costa Rica, has been characterized, since the last period of eruptive activity in 1884-1886, by a weak and discontinuous fumarolic activity in the wester...
Radon-in-soil monitoring at the Poas volcano (Costa Rica) has been performed together with water chemistry from the hot crater lake since 1981 and 1983 respectively. The results are discussed as a fu...
The equilibrium composition of volcanic gases with their magma is often overprinted by interaction with a shallow hydrothermal system. Identifying the magmatic signature of volcanic gases is critical ...
Background: Food fortification is one approach for addressing anemia, but information on program effectiveness is limited.
We investigated the spatial variability of picocyanobacterial community structure across the Costa Rica Dome(CRD), an offshore upwelling system characterized by high seasonal abundance of Synechococcu...
The World History Association, along with our gracious local host, the University of Costa Rica, are pleased to announce the 2014 WHA Costa Rica Conference. The dual themes of the conference will be T...
This dissertation chiefly examines the difficulties and principles of establishing sustainable ecotourism based on local communities. Furthermore, mainly address management techniques of sustainabilit...
The bamboo sector in Costa Rica is extremely small, as much in actors as in extension of plantations, that country has an important investigation process and technological development in cultivation a...
We report results of a 9-year monitoring program that took place from 2001 to 2009 of the helium and carbon isotope (3He/4He, δ13C) and relative abundances ratios (CO2/3He) of fumarole sites at Poás a...
At the end of the last decade many Latin American states initiated public security reform. This included police human rights strategies, which aim to improve police officers' compliance with human rig...
Problem statement: The tropics contain primary forests with a significant value for society, as they provide services such as carbon sequestration, soil conservation, bio-prospecting, water storage an...
A regional ocean circulation model with fine horizontal resolution has been developed in order to obtain a coherent seasonal picture of the eastern tropical Pacific off Central America. The Costa R...
Macrofungi of Costa Rica is a collaborative project between the Principal Investigators (Roy E. Halling & Gregory M. Mueller) with funding from the National Science Foundation (grant nos. DEB–9972018 ...
The Costa Rica upwelling dome (CRD; ~8.67°N and 90.6°W) was characterized chemically for cobalt and nickel abundances and speciation and biologically using cyanobacterial abundances and phylogeny. Tot...
