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 ...

Acta Botânica Brasílica, 2018 Fruits of Gevuina avellana (Proteaceae) seem to mimic wasp-induced galls of Nothofagus dombeyi (Nothofagaceae) to escape predation by rodents, which may change both spatially and temporarily.

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

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

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 ...

Fires in rainforests: Quantifying litter bed flammability of cool temperate rainforests in eastern Australia. [PDF]
Am J BotAbstract Premise Rainforests are usually too wet to burn, acting as natural barriers to fire spread and as refuges for biodiversity. However, climate change is increasing the risk of fire incursion into rainforests. Our capacity to manage these impacts is hindered by limited research on rainforest flammability.

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

Testing key tenets of pyro-ecophysiology: Indicators of drought response in relation to shoot flammability. [PDF]
Am J BotAbstract Premise Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro‐ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare.
