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 ...
Above-ground biomass storage potential in primary rain forests managed for timber production in Costa Rica
(Elsevier, Ámsterdam (Países Bajos), 2021-07)
Tropical forests play a fundamental role in mitigating climate change through storage of carbon in above- and below- ground biomass. Their mitigation potential is, however, affected by significant greenhouse gas emissions ...
Almacenamiento de carbono en sistemas agroforestales en los Llanos Orientales de Colombia
(2021-03)
Carbon storage in agroforestry systems in Colombia’s Eastern Plains. Introduction: Coffee, cocoa crops and pastures for livestock are agricultural activities of economic interest in Colombia. When these activities are ...
Intraspecific variation in biocontrol traits in Mastrus ridens (Hymenoptera: Ichneumonidae) laboratory populations
(Springer, Nueva York (Estados Unidos), 2021-05)
Breeding natural enemies to generate populations with improved characteristics is an attractive idea, particularly nowadays with the increase in use of biological control and the availability of modern molecular and genetic ...
Shade and Agronomic Intensification in Coffee Agroforestry Systems: Trade-Off or Synergy?
(2021)
Despite many years of research, there is still a lack of consensus as to the nature of the relationship between shade trees and agronomic intensification in coffee agroforestry systems. While some studies find unshaded ...
Prediction model for sap flow in cacao trees under different radiation intensities in the western Colombian Amazon.
(2021-01)
In this study, we measured diurnal patterns of sap fow (Vs) in cacao trees growing in three types of agroforestry systems (AFs) that difer in the incident solar radiation they receive. We modeled the relationship of Vs ...
Cacao cultivation as a livelihood strategy: contributions to the well‑being of Colombian rural households
(Springer, Nueva York (Estados Unidos), 2021-07)
Cacao cultivation is one of the most important livelihoods for rural households in Colombia, where it is promoted as a substitute for the illegal cultivation of coca. To strengthen Colombian cacao farming, it is important ...
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 ...
Permanence of PES and the role of social context in the Regional Integrated Silvo-pastoral Ecosystem Management Project in Costa Rica
(Elsevier, Ámsterdam (Países Bajos), 2021-07)
We present rare, empirical evidence on the permanence of land use changes induced by a payments for ecosystem services (PES) program. A follow-up study was conducted a decade after the end of the Regional Integrated ...
Genotype–environment interactions shape leaf functional traits of cacao in agroforests
(Springer, Nueva York (Estados Unidos), 2021)
The outbreak of frosty (Moniliophthora roreri) and black pod (Phytophthora palmivora) in Central American cacao agroforests throughout the 1980s led to the breeding of Theobroma cacao clones resistant to these diseases. ...
