Experimental field exclosure of birds and bats in agricultural systems — Methodological insights, potential improvements, and cost-benefit trade-offs
(ELSEVIER, 2019)Experimental exclosure of birds and bats constitutes a powerful tool to study the impacts of wildlife on pests and crop yields in agricultural systems. Though widely utilized, exclosure experiments are not standardized ... -
Extinction filters mediate the global effects of habitat fragmentation on animals
(Science, 2019)Habitat loss is the primary driver of biodiversity decline worldwide, but the effects of fragmentation (the spatial arrangement of remaining habitat) are debated. We tested the hypothesis that forest fragmentation ... -
Forecast models of coffee leaf rust symptoms and signs based on identified microclimatic combinations in coffee-based agroforestry systems in Costa Rica
(Elsevier, Ámsterdam (Países Bajos), 2019)Coffee leaf rust is a polycyclic disease that causes severe epidemics impacting yield over several years. For this reason, since the 1960s, more than 20 models have been developed to predict different indicators of the ... -
Genetic diversity and spatial structure in a new distinct Theobroma cacao L. population in Bolivia
(2015)Cacao (Theobroma cacao L.) is an important economic crop in the Bolivian Amazon. Bolivian farmers both cultivate cacao, and extract fruits from wild stands in the Beni River region and in valleys of the Andes foothills. ... -
Good data are not enough: Understanding limited information use for climate risk and food security management in Guatemala.
(2020)Climate extremes are one of the main drivers of acute food insecurity. In Guatemala, acute food insecurity reaches alarming levels when the usual dry period during the bimodal rainy seasons is extended or starts earlier ... -
Human pressure on water quality and water yield in the upper Grijalva river basin in the Mexico-Guatemala border
(ELSEVIER, 2016)Forest ecosystems are major providers of high quality water and contribute to maintain a better distribution of base flows during the year. However, these environmental services have been adversely affected by human pressure ... -
Impact of Shrimp Ponds on Mangrove Blue Carbon Stocks in Ecuador
(2021-06)Mangrove forests play an important role in mitigating climate change but are threatened by aquaculture expansion. The inclusion of mangroves in climate change mitigation strategies requires measuring of carbon stocks and ... -
Impacts of protected areas vary with the level of government: Comparing avoided deforestation across agencies in the Brazilian Amazon
(Proceedings of the National Academy of Sciences of the United States of America, 2019) -
Influence of topographic and edaphic factors on vulnerability to soil degradation due to cattle grazing in humid tropical mountains in northern Honduras
(2015-01-22)Low altitude humid tropical mountains in Central America have experienced a process of livestock expansion during recent decades. However, the use of sloping areas for cattle grazingmay lead to significant soil degradation and ... -
Información hidrológica, primer paso para diseñar una política local de pago por servicios ambientales
(2015)Los recursos hidrológicos tienen significativa importancia en países con problemas de escasez de agua, parte de los cuales se atribuyen a la inexistencia de una relación entre los proveedores de servicios ambientales y de ... -
Leaf functional traits and pathogens Linking coffee leaf rust with intraspecific trait variation in diversified agroecosystems
(PLOS, 2023-04-13)Research has demonstrated that intraspecific functional trait variation underpins plant responses to environmental variability. However, few studies have evaluated how trait variation shifts in response to plant pathogens, ... -
Leaf functional traits vary within and across tree species in tropical cloud forest on rock outcrop versus volcanic soil
(2019)Functional leaf traits are used to classify plants into ecological strategies according to the leaf economic spectrum. Geological substrate has an important effect on functional trait variation, however, interspecific and ... -
Long-term response of groundcover components to organic and conventional weed control in shaded and open-sun coffee in Nicaragua
(Crop protection, 2020)The weed-free period is employed to evaluate the effectiveness of practices to reduce crop loss to weeds. To orient sustainable cropping system approaches in perennial crops such as coffee which are often grown with trees, ... -
Making the post-2020 global biodiversity framework a successful tool for building biodiverse, inclusive, resilient and safe food systems for all
(IOP Publishing, Bristol (Reino Unido), 2020-08)COVID-19 has exposed the vulnerability of our economies to shocks, and it has laid bare deep inequalities in our society that threaten to derail the Sustainable Development Goals. Governments around the world are looking ... -
Marginal Abatement Cost Curves for Latin American dairy production: A Costa Rica case study
(Elsevier, Ámsterdam (Países Bajos), 2021-05)This study utilises data collected from Costa Rican dairy farmers to conduct a cradle to farm gate Life Cycle Assessment and the first Marginal Abatement Cost Curve (MACC) for dairy production in Latin America. Ninety dairy ... -
Measured ammonia emissions from tropical and subtropical pastures: A comparison with 2006 IPCC, 2019 Refinement to the 2006 IPCC, and EMEP/EEA (European Monitoring and Evaluation Programme and European Environmental Agency) inventory estimates
(American Dairy Science Association, Champaign, IL, EUA ; Elsevier, Ámsterdam, Países Bajos, 2020)Agriculture is the largest source of ammonia (NH3) emissions. As NH3 is an indirect greenhouse gas, NH3 measurements are crucial to improving greenhouse gas emission inventory estimates. Moreover, NH3 emissions have wider ... -
Microsatellite DNA fingerprinting of Coffea sp. germplasm conserved in Costa Rica through singleplex and multiplex PCR
(Crop Breeding and Applied Biotechnology, 2020)A large collection of coffee genetic resources is conserved in Costa Rica. In this study, microsatellite DNA fingerprinting of coffee through singleplex and multiplex PCR approaches coupled with capillary electrophoresis ... -
Old-growth neotropical forests are shifting in species and trait composition
(2016)Tropical forests have long been thought to be in stable state, but recent insights indicate that global change is leading to shifts in forest dynamics and species composition. These shifts may be driven by environmental ...
