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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 tree identity rather than diversity influences soil macrofauna in cacao-based agroforestry systems
(Elsevier, Ámsterdam (Netherlands), 2021-09)
Humanity is facing a rapid decline in global biodiversity, caused mainly by tropical deforestation through industrial and smallholder agriculture. However, smallholder agriculture landscapes host areas containing home ...
Dispersal limitation, soil, and fire affect functional properties of tropical secondary forests on abandoned cattle ranching landscapes
(2021)
Forest age is a major predictor of secondary forest functional properties and through the chronosequence approach continues to be a principal focus in local, landscape, and regional-scale studies of secondary succession. ...
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. ...
