Potencial dendroclimático de Nothofagus betuloides en la Cordillera de Darwin, Tierra del Fuego, Chile [PDF]
Bosque, 2017 El estudio de la variabilidad climatica en regiones remotas se dificulta por la escasez de series instrumentales largas y completas. Una alternativa es recurrir al uso de fuentes de informacion paleoambiental, tales como las series de anillos de crecimiento arboreo.

Efecto del vaporizado inicial en el secado artificial de madera de coigüe de Magallanes (Nothofagus betuloides)* [PDF]
Bosque, 2005 El trabajo consistio basicamente en someter madera aserrada de Nothofagus betuloides (Mirb.) Oerst. a tres distintos niveles de vaporizado inicial (4, 8 y 10 horas, respectivamente) y a un posterior proceso de secado artificial convencional unico. Se evaluo el efecto del vaporizado inicial sobre la calidad de la madera obtenida y el tiempo de secado ...

Forest Systems, 1994 N. betuloides (Fagaceae) is an economically important tree species from Fuegian forest (Argentina). The present work was carried out aiming to study the effects of gibberellic acid and potassium nitrate on the release of dormacy, and the presence of differences in germination of 2-winged and 3-winged.

Inferring population dynamic trends of Nothofagus pumilio and N. betuloides in coastal and mountain forests of Tierra del Fuego: contrasting from flowering to seedling survival through several reproductive cycles [PDF]
Trees - Structure and Function, 2021 Flower to fruits × and seed-to-seedling were the most critical transition in the early regeneration cycle of pure and mixed Nothofagus forests, both in coastal and mountain geographic locations. Within mixed forest, the deciduous N. pumilio shows better recruitment performance (e.g., highest transition probabilities) than the evergreen N.

Phylogenetic relationships and time-calibration of the South American fossil and extant species of southern beeches (Nothofagus) [PDF]
Acta Palaeontologica Polonica, 2018 The genus Nothofagus is considered as one of the most interesting plant genera, not only for the living species but also due to the fossil evidence distributed throughout the Southern Hemisphere. Early publications postulated a close relationship between

Structural and Biometric Characterization ofNothofagus betuloidesProduction Forests in the Magellan Region, Chile [PDF]
Journal of Sustainable Forestry, 2007 Summary This study, in die Chilean Magellan Region, undertook the structural and biometrie characterization of Nothofagus betuloides (Mirb.) Blume (coihue de Magallanes) production forests to provide information for sustainable forest management. Six locations were surveyed, five on the continent and one on Tierra del Fuego Island.

Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem. [PDF]
Mol EcolABSTRACT It is known that phenological changes (i.e., behavioural and sometimes morphological and physiological traits that repeat annually) influence the wildlife gut microbiota. However, it remains largely unknown to what extent geographic variation could modulate the effect that phenology has on wildlife microbiota.

Evidence of endozoochory in upland geese Chloephaga picta and white-bellied seedsnipes Attagis malouinus in sub-Antarctic Chile. [PDF]
Ecol Evol, 2021 Birds are known to act as potential vectors for the exogenous dispersal of bryophyte diaspores. Given the totipotency of vegetative tissue of many bryophytes, birds could also contribute to endozoochorous bryophyte dispersal. We evaluated the role of endozoochory in two herbivorous and sympatric bird species in sub‐Antarctic Chile and hypothesized that
