Genome-Wide Diversity in Lowland and Highland Maize Landraces From Southern South America: Population Genetics Insights to Assist Conservation. [PDF]

Evol Appl
ABSTRACT Maize (Zea mays ssp. mays L.) landraces are traditional American crops with high genetic variability that conform a source of original alleles for conventional maize breeding. Northern Argentina, one the southernmost regions of traditional maize cultivation in the Americas, harbours around 57 races traditionally grown in two regions with ...

The role of geography, ecology, and hybridization in the evolutionary history of Canary Island Descurainia

American Journal of Botany, Volume 110, Issue 5, May 2023., 2023
Abstract Premise Oceanic islands offer the opportunity to understand evolutionary processes underlying rapid diversification. Along with geographic isolation and ecological shifts, a growing body of genomic evidence has suggested that hybridization can play an important role in island evolution.

Variables that intervene in the weight of rotifer biomass and fatty acids

Journal of the World Aquaculture Society, Volume 53, Issue 3, Page 741-753, June 2022., 2022
Abstract The biomass of rotifers is used as live food in aquaculture; their quality is determined by the content of the main polyunsaturated fatty acids and the weight it acquires over time. The objective of this work was to evaluate the variables involved in this process to achieve higher quality.

The widely distributed, edible seaweeds in Peru, Chondracanthus chamissoi and Chondracanthus chamissoi f. glomeratus (Gigartinaceae, Rhodophyta), are morphologically diverse but not phylogenetically distinct

Journal of the World Aquaculture Society, Volume 52, Issue 6, Page 1290-1311, December 2021., 2021
Abstract Chondracanthus chamissoi is part of the diet of coastal people from Peru and is exported dehydrated to Asian countries for direct consumption. Although it is considered endemic to Peru and Chile, its range has extended to distant regions, such as Korea, Japan, and France. Using morphological and molecular approaches, we examined specimens from

The Key Role of Cultural Preservation in Maize Diversity Conservation in the Argentine Yungas

Evidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013
Farmers’ decisions on what to grow and why can contribute in understanding the conservation of agrobiodiversity. Culture and ethnicity are indicated as first‐class factors leading preservation of heirloom cultivars but this has been little considered in studies examining factors that influence the loss or preservation of agrobiodiversity.
