Assessing the dendroclimatic potential of Nothofagus betuloides (Magellan’s beech) forests in the southernmost Chilean Patagonia [PDF]
Trees, 2018 Tree growth of Nothofagus betuloides forests south of 50°S is affected by local temperature and precipitation together with large-scale high-latitude climate patterns, but also significant influences from the Tropical Pacific were found. The characterization of past climate dynamics in southern South America is difficult due to the shortness of ...

Plant Physiology and Biochemistry, 2023 Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this study, we analysed the wettability, anatomy and ultra-structure of leaves of Nothofagus antarctica (deciduous) and N.

Variabilidad topográfica y edáfica en bosques de Nothofagus betuloides (Mirb) Blume, en el suroeste de Tierra del Fuego, Chile [PDF]
Revista chilena de historia natural, 2007 Se investigo la variabilidad de las relaciones topograficas y edaficas en sitios con presencia de Nothofagus betuloides y especies arboreas asociadas en el suroeste de Tierra del Fuego. Estas relaciones se analizaron con metodos estadisticos bivariados y multivariados.

Efecto del vaporizado inicial en el secado artificial de madera de coigüe de Magallanes (Nothofagus betuloides)* [PDF]
Bosque (Valdivia), 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 ...

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2012 Abstract Old-growth forests present a mosaic of different conditions resulting from the natural forest structure of the stands. Nothofagus betuloides forests have high spatial variability in regeneration without a clear correlation with overstory, and could be related to location of the stands in the landscape.

International Journal of Biometeorology, 2009 The transmission of direct, diffuse and global solar radiation in and around canopy gaps occurring in an uneven-aged, evergreen Nothofagus betuloides forest during the growing season (October 2006-March 2007) was estimated by means of hemispherical photographs. The transmission of solar radiation into the forest was affected not only by a high level of

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.

Trees, 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.

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.

Habitat distribution modeling reveals vegetation flammability and land use as drivers of wildfire in SW Patagonia [PDF]
Ecosphere, Volume 4, Issue 5, Page 1-20, May 2013., 2013 Despite important recent advances in modeling current and future global fire activity in relation to biophysical predictors there remain important uncertainties about finer-scale spatial heterogeneity of fire and especially about human influences which ...
