Evaluation of data pre-processing and regression models for estimation of soil organic carbon using Vis–NIR spectroscopy in acid soils of Colombian tropical savanna
https://hdl.handle.net/10568/181918
Abstract
Soil organic carbon (SOC) plays a critical role
in terrestrial ecosystem functioning and
global climate regulation.
• The SOC pool in agricultural soils maintains
fertility, supports sustainable development,
and is essential for national food security
(Bangelesa et al. 2020).
• Rapid and accurate SOC estimation using
near-…

Differential agronomic trait responses of inbred and hybrid rice cultivars to rice–forage rotations
https://hdl.handle.net/10568/181914
Abstract
Integrating rotation into rice systems offers a promising opportunity to enhance soil health, improve nutrient cycling, and support long-term productivity (Chen at al., 2018). This approach aligns with the objectives of the Carbon Sequestration project, supported by the Bezos Earth Fund, which seeks to leverage genetic diversity and develop innovative root ideotypes in tropical forage…

Caregivers' nutritional knowledge and attitudes mediate seasonal shifts in children's diets
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/98259
Abstract
Smallholder farmers dependent on rain‐fed agriculture experience seasonal variationsin food and nutrient availability occasioned by seasonality of production patterns. This results in periods of nutrient abundance in the plenty seasons followed closely by periods of nutrient inadequacies and malnutrition. This pattern…

NTFP harvesters as citizen scientists: Validating traditional and crowdsourced knowledge on seed production of Brazil nut trees in the Peruvian Amazon
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/83368
Abstract
Understanding the factors that underlie the production of non-timber forest products (NTFPs), as well as regularly monitoring production levels, are key to allow sustainability assessments of NTFP extractive economies. Brazil nut (Bertholletia excelsa, Lecythidaceae) seed…

Abstract
Conservation priorities for Prunus africana, a tree species found across Afromontane regions, which is of great commercial interest internationally and of local value for rural communities, were defined with the aid of spatial analyses applied to a set of georeferenced molecular marker data (…

https://hdl.handle.net/10568/35761
Abstract
In Sub-Saharan Africa, 40% of children under five years in age are chronically undernourished. As new investments and attention galvanize action on African agriculture to reduce hunger, there is an urgent need for metrics that monitor agricultural progress beyond calories produced per capita and address nutritional diversity essential for human…

Screening genetic resources of Capsicum peppers in their primary centre of diversity in Bolivia and Peru
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/69456
Abstract
For most crops, like Capsicum, their diversity remains under-researched for traits of interest for food, nutrition and other purposes. A small investment in screening this diversity for a wide range of traits is likely to reveal many traditional varieties with distinguished values. One objective of this study was to…

Comparative phylogeography in rainforest trees from Lower Guinea, Africa
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/66079
Abstract
Comparative phylogeography is an effective approach to assess the evolutionary history of biological communities. We used comparative phylogeography in fourteen tree taxa from Lower Guinea (Atlantic Equatorial Africa) to test for congruence with two simple evolutionary scenarios based on physio-climatic features 1) the W-E environmental gradient…

New genes in traditional seed systems: diffusion, detectability and persistence of transgenes in a maize metapopulation
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/35817
Abstract
Gene flow of transgenes into non-target populations is an important biosafety concern. The case of genetically modified (GM) maize in Mexico has been of particular interest because of the country’s status as center of origin and landrace diversity. In contrast to maize in the U.S. and Europe, Mexican…

Transcriptome analysis of filling stage seeds among three buckwheat species with emphasis on rutin accumulation
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/90556
Abstract
Buckwheat is an important minor crop with pharmaceutical functions due to rutin enrichment in the seed. Seeds of common buckwheat cultivars (Fagopyrum esculentum, Fes) usually have much lower rutin content than tartary buckwheat (F. tartaricum, Ft). We previously found a wild species of common buckwheat (F.…

Fine-scale processes shape ecosystem service provision by an Amazonian hyperdominant tree species
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/97417
Abstract
Conspecific distance and density-dependence is a key driver of tree diversity in natural forests, but the extent to which this process may influence ecosystem service provision is largely unknown. Drawing on a dataset of >135,000 trees from the Peruvian Amazon, we assessed its manifestation in biomass accumulation and…

How effective are DNA barcodes in the identification of African rainforest trees?
Bioversity International (Bioversity International)
https://hdl.handle.net/10568/35565
Abstract
DNA barcoding of rain forest trees could potentially help biologists identify species and discover new ones. However, DNA barcodes cannot always distinguish between closely related species, and the size and completeness of barcode databases are key parameters for their successful application. We test the ability of rbcL, matK and trnH-psbA…
