Chirripó Hydrological Research Site: advancing stable isotope hydrology in the Central American Páramo
The Chirripó Hydrological Research Site (CHRS) is located within the Chirripó National Park, Costa Rica (between 3,100-3,820 m asl) whereby ~100 km2 are covered by Páramo, a high‐elevation tropical grassland ecosystem. A ...
Revisiting the fundamentals of p-nitrophenol analysis for its application in the quantification of lipases activity. A graphical update
(Universidad Nacional (Costa Rica), 2020-07-31)
p-Nitrophenol (pNP) is a widely used compound for analytical determinations of several esterases (EC. 3.1.1.X), including lipases (E.C. 18.104.22.168). Most enzymatic measurements employ pNP derivatives such as ...
Environmental isotope applications in Latin America and the Caribbean region
(Taylor & Francis, 2020-11)
This Special Issue illustrates the use of environmental isotopes in studying and assessing hydrogeological and ecohydrological issues in the Latin America and the Caribbean (LAC) region. The issue includes twenty selected ...
Tracing water sources and fluxes in a dynamic tropical environment from observations to modeling
(Frontiers in Earth Science, 2020-11-06)
Tropical regions cover approximately 36% of the Earth’s landmass. These regions are home to 40% of the world’s population, which is projected to increase to over 50% by 2030 under a remarkable climate variability scenario ...
Bayesian estimates of the mean recharge elevations of water sources in the Central America region using stable water
Study region: Central America. Study focus: Knowledge of the mean recharge elevation (MRE) of water resources is important where water resources are vulnerable. The purpose of this study was to develop and apply a Bayesian ...
Hydrogeochemical baseline in a human altered landscape of the Central Pacific coast of Costa Rica
(Springer Nature, 2020)
Abstract Groundwater pollution in tropical and human-altered coastal landscapes is receiving novel attention due to decreasing in annual recharge as a consequence of recurrent droughts and overexploitation, whereby saline ...
Hydrological dataset of a sub-humid continental plain basin (Buenos Aires, Argentina)
The Chaco-Pampean Plain (Argentina) is the strongest eco- nomic region and the most inhabited in the country, comprising approximately 66% of the country’s population (26,500 million)  . In this region, surface slopes ...
