Regeneración de un bosque mixto de Nothofagus (Nothofagaceae) después de una corta selectiva Regeneration of a Nothofagus (Nothofagaceae) mixed forest after selective cutting

Revista Chilena de Historia Natural, 2003
El estudio de la ecología de la regeneración natural del bosque constituye una parte esencial de la silvicultura. El cerro Tren Tren (40°12' S, 71°26' O, 1.367 m, Reserva Mapuche Curruhuinca, Argentina) está ocupado por un bosque cerrado compuesto por ...

Crecimiento y ramificación de Nothofagus alpina y Nothofagus obliqua (Nothofagaceae) bajo diferentes condiciones lumínicas Growth and branching in Nothofagus alpina and Nothofagus obliqua (Nothofagaceae) under different light conditions

Boletín de la Sociedad Argentina de Botánica, 2013
Summary: Growth and branching in Nothofagus alpina and Nothofagus obliqua (Nothofagaceae) under different light conditions. Architectural traits of entire main branches and their growth units (GUs) were assessed for trees of Nothofagus alpina and N ...

Variaciones Intra-Específicas en el crecimiento primario de Nothofagus dombeyi (Nothofagaceae) Intra-specific variations in the primary growth of Nothofagus dombeyi (Nothofagaceae)

Boletín de la Sociedad Argentina de Botánica, 2005
Se evaluó el patrón de crecimiento bajo condiciones controladas de los ejes foliados de 16 plántulas de Nothofagus dombeyi. Los individuos fueron ubicados en una cámara de crecimiento y se evaluó el crecimiento del tronco en dos eventos de crecimiento ...

Nature vs nurture in the leaf morphology of Southern beech, Nothofagus cunninghamii (Nothofagaceae) [PDF]

New Phytologist, 2003
•  Leaf morphology varies predictably with altitude, and leaf morphological features have been used to estimate average temperatures from fossil leaves. The altitude-leaf morphology relationship is confounded by the two processes of acclimation and adaptation, which reflect environmental and genetic influences, respectively.

Morfología y Anatomía del Ápice Caulinar de Nothofagus dombeyi (Nothofagaceae) a lo largo de un año Morfology and anatomy of the shoot apex of Nothofagus dombeyi (Nothofagaceae) along a year

Boletín de la Sociedad Argentina de Botánica, 2006
En el presente estudio se evaluó la posible variación anual de la morfología y la anatomía del ápice caulinar de coihue, Nothofagus dombeyi (Nothofagaceae). A partir de muestras tomadas a lo largo de un año calendario, se realizaron cortes longitudinales

Phylogenetic relationships in Nothofagus: The role of Antarctic fossil leaves [PDF]

Acta Palaeontologica Polonica, 2023
The Nothofagus (southern beech) has a rich fossil record and a number of living species distributed exclusively in the Southern Hemisphere. Many attempts have been made to clarify the phylogenetic relationships in Nothofagus but only a few works have ...

Complex History of Organellar Introgression in <i>Nothofagus</i> Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection. [PDF]

Ecol Evol
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Genome duplications, genomic conflict, and rapid phenotypic evolution characterize the Cretaceous radiation of Fagales. [PDF]

J Integr Plant Biol
Fagales show “early burst” model of phenotypic disparification, with morphospace being filled during the early radiation of the Fagales crown and its major families. The elevated levels of phenotypic evolution often correspond to hotspots of gene duplication, whereas species diversification is decoupled from both phenotypic and genomic evolution ...

Diversity-Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent. [PDF]

Ecol Evol
We investigated diversity patterns of vascular plants of overstorey and understorey vegetation separately per stratum and the influence of anthropogenic disturbances along two elevational transects with contrasting slope aspects in a temperate rainforest and alpine scrub in southern Chile.

Bark-associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes. [PDF]

Plant Biol (Stuttg)
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.
