(Springer, 2021)Nothofagus alpina (Poepp. and Endl.) Oerst. (= N. nervosa (Phil.) Dim. et Mil.), raulí, is an iconic forest tree species of the South American temperate forests due to its hardwood quality. With a pinkish colour and light ... -
Respuestas a la temperatura en especies del género Nothofagus distribuidas en un gradiente altitudinal
(Edición del Autor, 2019-03-07)Las predicciones del Cambio Clim´atico Global para el noroeste de la Patagonia indican un aumento de la temperatura media, acompañado de mayor frecuencia de eventos extremos. En este contexto, es fundamental comprender la ... -
Respuestas morfológico-fisiológicas ante distintos tipos e intensidades de estrés en dos especies patagónicas del genéro Nothofagus con aptitud comercial
(Facultad de Agronomía, Universidad de Buenos Aires, 2010-09)Algunas especies nativas andino - patagónica poseen alto valor maderero. La utilización de las mismas en cultivo requiere del conocimiento de su respuesta fisiológica y morfológica frente a factores ambientales generadores ... -
Roble pellín (Nothofagus obliqua): A Southern Beech with a Restricted Distribution Area But a Wide Environmental Range in Argentina
(Springer, 2021)Nothofagus obliqua (Mirb.) Oerst. (Nothofagaceae, Hill and Jordan 1993), known as ‘roble’, ‘pellín’, ‘roble pellín’ or ‘hualle’, is a tree species endemic to South American temperate forests. It is under protection in ... -
Robles in Lagunas de Epulauquen, Argentina: previous and recent evidence of their distinctive character
(2014-12)The northernmost ‘robles’ of Argentina, located in Lagunas de Epulauquen (northwest Patagonia), are considered a population of Nothofagus obliqua, even though they differ in some respects from individuals of other populations ... -
Searching for molecular insight on hybridization in Nothofagus spp. forest at Lagunas de Epulauquen, Argentina = Estudio de la hibridación a nivel molecular en bosques de Nothofagus spp. en Lagunas de Epulauquen, Argentina
(2016)Los bosques en Lagunas de Epulauquen (36º49’S; 71º04’O) han sido considerados como la población más septentrional de Nothofagus obliqua en Argentina. En años recientes se ha cuestionado su verdadero estatus. La convergencia ... -
Seed dormancy responses to temperature relate to Nothofagus species distribution and determine temporal patterns of germination across altitudes in Patagonia
(2015-08-26)Seeds integrate environmental cues that modulate their dormancy and germination. Although many mechanisms have been identified in laboratory experiments, their contribution to germination dynamics in existing communities ... -
Seedling drought stress susceptibility in two deciduous Nothofagus species of NW Patagonia
(2010-06)The physiological capacities of seedlings to cope with drought may be subject to strong selective pressure in the context of future climate scenarios, threatening the regeneration and sustainability of forests. Characterization ... -
Shaping forces modelling genetic variation patterns in the naturally fragmented forests of a South-American Beech
(Elsevier, 2009-10)Fourteen natural populations of the South-American Beech Nothofagus obliqua at the Eastern naturally fragmented area of its distribution range were subjected to genetic analysis using genetic markers. The genetic ... -
