Contribution of agricultural land uses to bird conservation: a case study of ecosystem service provisioning
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), 2016)
Understanding the contribution of agricultural land uses to biodiversity conservation is of utmost importance. With 38% of earth’s ice free land surface covered by crops and pastures, studying and understanding the potential ...
Effects of tropical forest fragmentation on ecology and conservation of migrant and resident birds in lowland Costa Rica
(University of Idaho, Moscow, ID (EUA), Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), Turrialba (Costa Rica), 2007)
The overall objetive of my research was to understand the value of forest fragments to a diverse group of rainforest birds that depend on lowland tropical rainforest for their survival at one part or all of their annual ...
Mammal diversity, threats and knowledge across spatial scales
(University of Idaho, Moscow, ID (EUA), Centro Agronómico Tropical de Investigación (CATIE), Turrialba (Costa Rica), 2010)
Herein we provide a global dataset and analysis framework to address declines in mammal populations and ultimately extinction risk. By making this data freely and publically available we hope that it can bring the best ...
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 ...
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 ...
Landscape effects on insect pests of Dracaena marginata and their associated natural enemies in Costa Rica
(CATIE, Turrialba (Costa Rica), 2012)
This study examined how the landscape in which D. marginata is embedded affected the abundance and distribution of these three insect pest groups and their associated natural enemies. In order to evaluate the effect of the ...
Forest ecosystem responses to edge effects and secondary forest development in northeastern Costa Rica: implications for conservation
(University of Idaho, Moscow, ID (EUA), Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), Turrialba (Costa Rica), 2007)
Forest structure was examined at 20+ year old forest-pasture edges to assess edge effects. Stem density was significantly higher at forest edges than interiors due to an increase in small diameter trees close to edges. ...
Payments for environmental services in Costa Rica: conservation and production decisions within the San Juan - La Selva Biological Corridor
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), Turrialba (Costa Rica) University of Idaho, Moscow, ID (EUA), 2007)
This dissertation develops a model linking social and ecological theories to explain this interaction. This model is applied to Costa Rica’s program of payments for environmental service (PES) as a case example. The model ...
The effects of local and landscape context on leafhopper (Hemiptera: cicadellinae) communities in coffeee agroforestry system of Costa Rica
(CATIE, Turrialba (Costa Rica)
University of Idaho, Moscow, ID (EUA), 2008-05)
This study examined the effects of local (shade composition, organic or conventional management, and weed management) and landscape (surrounding land uses) context on sharpshooter communities in coffee agroforestry systeMON ...
