Decoupled Climatic Drivers of Tree and Ground-Layer Carbon Uptake in Mountain Ecosystems Around the World. [PDF]

Glob Chang Biol
Across four continents, we investigated how temperature controls the productivity of high mountain vegetation. We found that the productivity of plants growing close to the ground (< 1 m) tends to be controlled by highly localised “microclimate” temperatures, while the productivity of trees was strongly linked to broader‐scale temperatures.

Impact of protection methods and abiotic factors on Nothofagus pumilio seedlings mortality in Torres del Paine National Park, Chile

, 2023
National parks (NP) are the last refugia of forests dominated by the Nothofagus species in Chile. However, frequent, careless human-caused fires are destroying these forests even within the national parks. After large-scale fires, N.

Photosynthetic response to different light intensities and water status of two main Nothofagus species of southern Patagonian forest, Argentina

Journal of Forest Science, 2009
Net photosynthetic rate (A) and stomatal conductance (gs) of leaves of Nothofagus pumilio and N. an-tarctica seedlings were measured at different photosynthetic photon flux densities (PPFDs, 20, 150, 250, 500, 750, 1,000, 1,500 and 2,200 μmol/m2/s) and ...

Impacts of fire severity and cattle grazing on early plant dynamics in old-growth Araucaria-Nothofagus forests

Forest Ecosystems, 2019
Background Fire has historically shaped the dynamics of Araucaria araucana-Nothofagus pumilio forests in the Andean region of South America. Nevertheless, human disturbances and stronger drought events have resulted in increased occurrence and severity ...

Forest management with variable retention impact over bryophyte communities of Nothofagus pumilio understory [PDF]

, 2008
Bryophyte communities are an essential component of the understory in temperate forest, but few works analyze their potential as habitat indicators. Bryophytes, as the other plant species and wildlife, were significantly affected after the harvesting ...

MODIS Time Series Reveal New Maximum Records of Defoliated Area by Ormiscodes amphimone in Deciduous Nothofagus Forests, Southern Chile

Remote Sensing, 2023
Outbreaks of the Ormiscodes amphimone moth are among the largest biotic disturbances in South America, defoliating vast areas of native Nothofagus pumilio forests in the Chilean and Argentinian Patagonia in the last decade.

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

Botanical 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]

Journal 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.

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

, 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.
