Characterisation and transferability of transcriptomic microsatellite markers for Nothofagus species
(2017-07)Discriminant molecular markers are required for research on population genetics, as well as evolutionary studies involving identification of hybrids and parental species, or detection of the genome regions under selection. ... -
Clone differences among young Salix humboldtiana Willd. from Patagonia
(Springer, 2023-09)Willows represent some of the most extended tree crop species worldwide. Understanding their global architecture could help improving the forestry based on these species and thus the associated economic activities. Our ... -
Differentiation in phenology among and within natural populations of a South American Nothofagus revealed by a two-year evaluation in a common garden trial
(Elsevier, 2020-03-15)Phenological traits are crucial for understanding adaptation to climate change due to their genetic control and association with abiotic factors. However, few data on phenology patterns are available for South American ... -
Efecto del nivel de alimentación sobre la producción de lana de dos líneas genéticas de ovinos
(Asociación Argentina de Producción Animal, 2010-07)A los fines de estudiar si ovinos genéticamente más productivos son también más eficientes en la conversión de alimento en lana y si esa eficiencia se mantiene en diferentes ambientes nutricionales se realizó un ensayo con ... -
Estimation and analysis of insect population dynamics parameters via physiologically based models and hybrid genetic algorithm MCMC methods
(Elsevier, 2023-11)Decision support systems are gaining importance in several fields of agriculture, forest, and ecological systems management. Their predictive potential, entrusted to mathematical models, is of fundamental importance to set ... -
Genetic progress and economic benefit of community-based breeding programs for sheep out- and upscaling options in Ethiopia
(Elsevier, 2019-08)In this study, expected genetic progress and economic benefits from implementing three community-based breeding programs for sheep (CBBP) out- and upscaling strategies were investigated. Strategy 1 is to replicate average ... -
Genetic versus environmental contributions to variation in seedling resprouting in Nothofagus obliqua
(Springer, 2015-04)Resprouting is an almost universal functional trait in temperate angiosperms and confers persistence at an individual level after the loss of above-ground biomass. The importance of genetic versus environmental sources of ... -
How to succeed in implementing community-based breeding programs: Lessons from the field in Eastern and Southern Africa
(Frontiers Media, 2023-03)Breeding programs involving either centralized nucleus schemes and/or importation of exotic germplasm for crossbreeding were not successful and sustainable in most Africa countries. Community-based breeding programs (CBBPs) ... -
Identificación del origen genético de un rodal semillero implantado de Nothofagus obliqua a través del análisis de dos regiones inter-génicas de ADN de cloroplasto
(Ediciones INTA, 2021-04)En planes de forestación, tanto con fines productivos como de conservación, la correcta elección de la fuente de semilla para utilizar es un factor clave. El área productora de semilla (APS) “Trevelin” de Nothofagus obliqua ... -
Identification of Brucella ovis exclusive genes in field isolates from Argentina
(2016)La brucelosis ovina es una enfermedad infecciosa de curso crónico causada en nuestro país por Brucella ovis (B. ovis). Esta enfermedad constituye un problema importante para la producción ovina del país, especialmente en ... -
Integrating genetics and suitability modelling to bolster climate change adaptation planning in Patagonian nothofagus forests
(2017)We investigated the impact of past changes in habitat suitability on the current patterns of genetic diversity of two southern beeches (Nothofagus nervosa and Nothofagus obliqua) in their eastern fragmented range in ... -
Native Forests Claim for Breeding in Argentina: General Concepts and Their State
(Springer, 2021)The first genetic studies on forest trees in Argentina were carried out with exotic fast-growing species and in relation to their productive use. These antecedents, conducted mainly by the National Institute of Agricultural ... -
