Morphological and architectural features of young Nothofagus pumilio (Poepp. & Endl.) Krasser (Fagaceae) [PDF]

open access: yesBotanical Journal of the Linnean Society, 1999
The morphology and architecture of young Nothofagus pumilio plants growing as understorey and in a cleared area were assessed. Length, number of internodes, presence of branches and apex condition were registered for each growth unit (GU) in the sampled plant. GUs were grouped according to branching order and age of the bearing axis. Understorey plants

Isozyme Polymorphisms Provide Evidence of Clinal Variation With Elevation in Nothofagus pumilio [PDF]

open access: yesJournal of Heredity, 2003
Variable physical conditions along elevational gradients strongly influence patterns of genetic differentiation in tree species. Here, the hypothesis is tested that different growth forms of Nothofagus pumilio, which characterizes the subalpine forests in the southern Andes, will display continuous genetic variation with elevation.

Forty years of silvicultural management in southern Nothofagus pumilio primary forests

open access: yesForest Ecology and Management, 2004
To achieve sustainability of a forest system it is necessary to apply appropriate silvicultural management, including preservation measures. The characterization of the status and development of the harvested stands, as well as the timber potential of the unmanaged ones, is necessary to achieve a sustainable forest management.

Analysis of Nothofagus pumilio and Nothofagus antarctica Hybridization Zones in Southern Chile

open access: yes, 2023
Interspecific hybridization is documented in various tree species, including the three types of Nothofagus species (N. pumilio, N. antarctica, and N. betuloides) unique to Southern Patagonia. Previous studies found that hybridization results in developmental instability, which is reflected in the increase of leaf fluctuating asymmetry.

Tree health influences diameter growth along site quality, crown class and age gradients in Nothofagus forests of southern Patagonia

open access: yesJournal of Forest Science, 2013
We examined the influence of tree health on annual diameter increment of trees along gradients in stand site quality, crown classes and tree age in Nothofagus pumilio forests of Southern Patagonia.

Tree seedlings respond to both light and soil nutrients in a Patagonian evergreen-deciduous forest.

open access: yesPLoS ONE, 2017
Seedlings of co-occurring species vary in their response to resource availability and this has implications for the conservation and management of forests.

New insights into postglacial vegetation dynamics and environmental conditions of Península Avellaneda, southwest Patagonia, revealed by plant macrofossils and pollen analysis [PDF]

open access: yesMires and Peat, 2018
Reconstruction of the history of past events becomes more objective when considering an increased number of possible indicators. Combining plant macrofossil analysis with pollen analysis has the potential to give a more detailed picture of the ...

A Qualitative Methodologic Proposal to describe regeneration on Nothofagus pumilio forests

open access: yesForest Systems, 1993
It's presented a new methodologic proposal to be applied in Nothofagus pumilio forests. It arranged by relating on a qualitative way, certain regeneration variables with canopy cover and understory abundance. The field evaluation is quick and it is suggested like an accomplishment of large studies such as Forest Inventories, installation of Permanent ...

Functional ecology of Nothofagus pumilio regeneration in relation to light availability = Ecología funcional de la regeneración de lenga (Nothofagus pumilio) respecto a la disponibilidad de luz

open access: yesCiencia & Investigación Forestal, 2021
Las propuestas silvícolas de los bosques de Nothofagus pumilio se basan en la apertura del dosel para estimular el crecimiento de la regeneración, cambiando la disponibilidad de agua y luz. Las plántulas sobreviven como si fueran especies tolerantes y crecen lentamente por largo tiempo (más de 20 años) bajo altas coberturas.

Soil and Forest Degradation Driven by Cattle Grazing and Selective Logging in Sub‐Antarctic Nothofagus Ecosystems of Patagonia

open access: yesLand Degradation &Development, Volume 37, Issue 14, Page 10532-10545, 30 August 2026.
ABSTRACT Soil and forest degradation driven by chronic land‐use pressures is an increasingly widespread process in forested landscapes worldwide, yet its empirical characterization remains limited, particularly in temperate and sub‐Antarctic ecosystems.
