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 ...
The effect of different levels of tree cover on milk production in dual-purpose livestock systems in the humid tropics of the Colombian Amazon region
(Springer, Nueva York (Estados Unidos), 2020)
Abstract Caqueta´, Colombia, has a bovine population of 1,809,702 head, of which 88% are in dual purpose livestock systems; it ranks fifth in milk production at the national level. The aim of this study was to evaluate the ...
Total litterfall and leaf‑litter decomposition of Theobroma grandiflorum under different agroforestry systems in the western Colombian Amazon
(Springer, 2023)
The objective of this study was to quantify the amount of litter accumulated on the soil and the rate of decomposition in multistrata successional agroforestry systems with Theobroma grandiflorum as mainly crop, compared ...
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 ...
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 ...
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 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 ...
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 ...
