Genomic Variation and Population Structure of Portuguese Native Dog Breeds. [PDF]

Anim Genet
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle. [PDF]

Conserv Biol
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Species distribution modeling and conservation assessment of the northwestern Argentinian highland papayas under global change scenarios

Ecología Austral, 2022
Wild species related to crops are a source of genes for improving crop tolerance of biotic and abiotic stresses. Vasconcellea quercifolia and V. glandulosa are wild relatives of papaya (Carica papaya).

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
