Monografía de lenga Nothofagus pumilio

1998
La lenga crece desde la provincia del Ñuble hasta el Cabo de Hornos. Es la especie de mayor distribución en la Patagonia, donde se encuentran bosques de gran valor comercial. Alcanza 20-25 m. de altura y 60-80 cm. de DAP. Los crecimientos varían entre 3 y hasta 4 o 5 m/ha/año para bosques sin manejo y de hasta 9,5 m³/ha/año en rodales intervenidos.

Role of abiotic factors in Nothofagus pumilio forest mortality: The sensitivity of ecotones

Forest Ecology and Management, 2021
Abstract The world's forests are being affected by a changing climate. Recently, patches of dead trees have been found in forests of the Patagonian endemic species Nothofagus pumilio, which could not be related to insects or pathogenic fungi acting as primary agents. This study aimed to analyze environmental variables associated with N.

Notes on the dynamics and decomposition of leaves in a Nothofagus pumilio forest

Environmental Monitoring and Assessment, 1994
A research project was conducted in a native forest of Nothofagus pumilio in one of the southernmost Chilean Nation Parks, Torres del Paine, to check the amount and timing of leaf fall, their decomposition rate and the respiration rate of the soil on an annual cycle.This paper also provides the results of the decay of fallen leaves in time, the loss ...

Microclimate within a Nothofagus pumilio forest and the effects of a regeneration felling

2017
The forest microclimate in a Nothofagus pumilio primary forest (BV) and the effect of a regeneration felling (RG) and an open field (SD) were studied during seven years. Three weather stations measured the global solar radiation (RSG), the air temperature (Ta), the soil temperature at 15 (TS15) and 30 (TS30) cm depth, the relative humidity (HRa) and ...

Litter fluxes and decomposition in Nothofagus pumilio stands in the region of Magallanes, Chile

Forest Ecology and Management, 2001
Abstract Seasonal and annual litter fluxes, potential nutrient returns, and litter decomposition were evaluated in two stands, one natural stand and the other under a shelterwood system, within a natural Nothofagus pumilio forest located in the region of Magallanes, Chile.

Wood‐rotting fungi on Nothofagus pumilio in Patagonia, Argentina

European Journal of Forest Pathology, 1995
SummaryThe presence of basidiomes of wood‐decay fungi on living lenga (Nothofagus pumilio) was investigated in seven forest stands in Patagonia (Argentinia). The following species accounted for 85% of the rots: Postia pelliculosa, Phellinus andinopatagonicus, Piptoporus portentosus, Aurantioporus albidus, and Serpula himantoides. Ph.

Use of thin sections to improve age estimates of Nothofagus pumilio seedlings

Ecoscience, 2007
ABSTRACT This paper reports the use of thin sections to improve precision and accuracy when ageing seedlings of Nothofagus pumilio. We compare 2 methods for determining the number of rings on 85 basal disks from seedlings: (1) ring counts of wood disks viewed with reflected light and (2) ring counts of thin sections viewed with transmitted light ...

Soil–plant relationships and tree distribution in old growth Nothofagus betuloides and Nothofagus pumilio forests of Tierra del Fuego

Geoderma, 2005
The evergreen Nothofagus betuloides and deciduous Nothofagus pumilio live close together in Tierra del Fuego. The fact that these two species rarely form mixed forests suggests that the soil factor can contribute to the distribution of two species on a local scale.

Trunk and main-branch development in Nothofagus pumilio (Nothofagaceae): a retrospective analysis of tree growth

Canadian Journal of Botany, 2002
The development of the trunk and main branches of approximately 26-year-old Nothofagus pumilio (Poepp. et Endl.) Krasser trees was studied. The length and number of leaves of annual shoots were recorded for 56 trees from a natural population. Morphological and macroanatomical features allowed the identification of shoot apex deaths and the axillary ...

Litter decomposition in Nothofagus pumilio stands in Magallanes Region

2017
Litter decomposition in two Nothofagus pumilio stands located in Magallanes Region (Chile) was studied during two years. One stand was a primary forest (SI), without silvicultural treatment, and the other had a regenerative felling under a shelterwood system (CR). Weight loss and litter decomposition rates were obtained with the litter-bag method.
