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 ...
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 ...
Agronomic conditions of cacao cultivation: its relationship with the capitals endowment of Colombian rural households
(Springer, Nueva York (Estados Unidos), 2020)
Abstract Cacao cultivation has great socioeconomic importance for the development of rural areas of Colombia, especially for the approximately 52,000 rural households that depend on it. Therefore, is important to analyze ...
Altitude and species identity drive leaf litter decomposition rates of ten species on a 2950 m altitudinal gradient in Neotropical rain forests
(2019)
Identifying the environmental factors controlling litter decomposition is key to understanding the magnitude and rates of nutrient cycling in tropical forests, and how they may be influenced by climate variability and ...
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 ...
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 ...
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 ...
