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. ... -
Clinal variation along precipitation gradients in Patagonian temperate forests: unravelling demographic and selection signatures in three Nothofagus spp.
(Springer Nature, 2020-01-10)Past demographic changes and current selection pressures determine the genetic variation displayed by Nothofagus species along rainfall gradients. Based on the diversity trends observed at candidate genes associated to ... -
Deciphering the transcriptomic regulation of heat stress responses in Nothofagus pumilio
(Plos One, 2021-03-30)Global warming is predicted to exert negative impacts on plant growth due to the damaging effect of high temperatures on plant physiology. Revealing the genetic architecture underlying the heat stress response is therefore ... -
Dendrogeomorphic reconstruction of flash floods in the Patagonian Andes
(Elsevier, 2015-01-01)Flash floods represent a significant natural hazard in small mountainous catchments of the Patagonian Andes and have repeatedly caused loss to life and infrastructure. At the same time, however, documentary records of past ... -
Desarrollo temprano del roble (Nothofagus obliqua): un análisis arquitectural de procedencias de Argentina = Early development of roble (Nothofagus obliqua): an architectural analysis of provenances from Argentina
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2006-04-28)Se estudió el desarrollo arquitectural en tres años de plántulas de Nothofagus obliqua bajo condiciones de vivero. Las plántulas derivaron de semillas de cinco procedencias dentro del área de distribución natural de esta ... -
Development of genomic resources for Nothofagus species using next‐generation sequencing data
(Wiley, 2014-11)Using next‐generation sequencing, we developed the first whole‐genome resources for two hybridizing Nothofagus species of the Patagonian forests that crucially lack genomic data, despite their ecological and industrial ... -
Diagramas de manejo de densidad para renovales de roble, raulí y coigüe en Chile = Stocking management charts for roble, raulí and coigüe second growth forests in Chile
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2007)A total of 214 permanent and temporary plots from roble (Nothofagus obliqua ), raulí (N. alpina) and coigüe (N. dombeyi) pure and mixed second growth forests located between 37°30 and 42°00 south latitude in Chile were ... -
Different drought‑adaptive capacity of a native Patagonian tree species (Nothofagus pumilio) resulting from local adaptation
(Springer, 2021-06)The resistance of different genotypes to abiotic stress may be due to genetic effects and/or to phenotypic plasticity allowing them to acclimate to variable conditions. The contribution of one or the other mechanism ... -
Differential response of natural regeneration to silvopastoral use intensity in mixed forests of northern Patagonia, Argentina
(Elsevier, 2022-07-07)Silvopastoral use (combined livestock and forestry) is widely distributed in South America’s native forests. Without medium to long-term planning, this activity may affect the population dynamics of the dominant canopy ... -
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 ... -
