Estimation of aquifer recharge measured by the isotopic fractionation of water vapor and the hydrological balance of the soil in the dry tropical forest of Costa Rica
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), 2022)
It develop an approach of an hourly, lumped, conceptual, tracer-aided water balance model that simulates aquifer recharge in a dry tropical forest in Costa Rica. The model considers evaporative fractionation by estimating ...
Strategic planning for sustainable organic hillside agriculture with a farming system and value chain model in Nicoya, Guanacaste
(CATIE, Turrialba (Costa Rica), 2017)
La enfermedad de la roya anaranjada que se da en el café, es causada por el patógeno llamado Hemileia vastatrix. Este es un hongo que causa pérdidas económicas a este cultivo, como las producidas durante el ataque del ...
A geospatial data integration framework for mapping and monitoring tropical landscape diversity in Costa Rica's San Juan-La Selva Biological Corridor
(CATIE, Turrialba (Costa Rica), 2006)
Landcover change has substantially reduced the amount of tropical rain forests since the 1950s. Little is known about the extent of remaining forest types. A multivariate analysis of 144 forest plots across Costa Rica's ...
Distribution and foraging by the leaf-cutting ant, Atta cephalotes L., in coffee plantations with different types of management and landscape contexts, and alternatives to insecticides for its control
(CATIE, Turrialba (Costa Rica). Universidad de Idaho, ID (EUA), 2006)
Atta cephalotes L., the predominant leaf-cutting ant species found in coffee farMON in the Turrialba region of Costa Rica, is considered a pest of the crop because it removes coffee foliage. I applied agroecosystem and ...
Estimation and use of modified prior probabilities for digital classification improvement of tropical forests
(CATIE, Turrialba (Costa Rica), 2000)
This dissertation addresses the problem of tropical forest classification using remotely sensed data. Traditional remote sensing methods have had probleMON for discriminating tropical secondary and disturbed forests. As ...
Effects of deforestation and riparian buffers on lotic communities in Southeastern Costa Rica: implications for biodiversity conservation in tropical streams
(CATIE, Turrialba (Costa Rica), 2007)
To examine the effects of deforestation on stream communities in southeastern Costa Rica and test the hypothesis that riparian forest buffers can reduce these effects, comparisons were made between forested stream reaches ...
Effects of habitat fragmentation on the reproductive ecology and conservation genetics of the almendro (Dipteryx panamensis), a keystone rainforest tree
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), Turrialba (Costa Rica), University of Idaho, Moscow, ID (EUA), 2006)
Deforestation in the tropics creates a mosaic of forest patches embedded in a human-dominated matrix. Maintaining biodiversity in these fragmented landscapes relies on their ability to sustain ecological processes. This ...
Análisis del efecto de infraestructura verde para la protección del recurso hídrico en las microcuencas del rio Segundo y río Ciruelas, Heredia, Costa Rica
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), 2022)
La implementación de infraestructura verde como proyectos de conservación de suelo y agua a nivel local es importante en la gestión integrada de los recursos hídricos por la medidas preventivas y correctivas que ofrecen ...
Response of dwarf elephant grass (Pennisetum purpureum Schum) to different frequencies and intensities of grazing in the humid zone of Guápiles, Costa Rica
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), Turrialba (Costa Rica), 1990)
Cost-benefit analysis of manure applications on specialized dairy farms in the highlands and lowlands of Costa Rica
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), 2019)
The objective of this study is to estimate the value of manures for dairy farm pastures through a cost-benefit analysis (CBA) by quantifying manure- N content and costs for manure application. This work focuses on Intensive ...
