Species interactions across trophic levels mediate rainfall effects on dryland vegetation dynamics
(2020)
Arid ecosystems are strongly limited by water availability, and precipitation plays a 2 major role in the dynamics of all species in arid regions, as well as the ecosystem processes that 3 occur there. However, understanding ...
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 ...
Efecto de fitohormonas y fertilizantes sobre el enraizamiento y crecimiento de mini-estaquillas de híbridos F de café (Coffea arabica)
(2020)
[Introducción]: En el Centro Agronómico Tropical de Investigación y Enseñanza (CATIE) se está buscando optimizar
la técnica hortícola de enraizamiento de mini-estaquillas de café para la multiplicación comercial de ...
Shade tree Chloroleucon eurycyclum promotes coffee leaf rust by reducing uredospore wash-off by rain
(Elsevier, Ámsterdam (Países Bajos), 2020)
addition, may interact with environment. To better understand shade trees effects on coffee leaf rust (CLR), we
studied three disease stages separately: sporulation, uredospore wash-off by rain, and uredospore deposition ...
The positive association between natural vegetation, native coccinellids and functional diversity of aphidophagous coccinellid communities in alfalfa
(2021-01)
1. A greater taxonomic and functional diversity of natural enemies in agroecosystems is frequently positively associated with more effective pest control, due to the complementarity of species or traits. But this diversity ...
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 ...
Unraveling the Complexity of Coffee Leaf Rust Behavior and Development in Different Coffea arabica Agroecosystems
(2020)
Crop health management systems can be designed according to practices that help to reduce crop losses by restricting pathogen development and promoting host plant growth. A good understanding of pathogen and host dynamics, ...
Economic constraints as drivers of coffee rust epidemics in Nicaragua
(Elsevier, Ámsterdam (Países Bajos), 2020)
Coffee rust (Hemileia vastatrix) epidemics of an intensity never seen before have hit Central America since 2012.
This study set out to identify management and socio-economic factors that facilitate coffee rust development ...
Cacao agroforestry systems improve soil fertility: Comparison of soil properties between forest, cacao agroforestry systems, and pasture in the Colombian Amazon
(Elsevier, Ámsterdam (Países Bajos), 2021-01)
The objective of our work was to evaluate soil quality in different cacao agroforestry systems (AFS) in the Colombian Amazon. We compared soil quality of AFS at the study site with soil quality of two control systems: a ...
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 ...
