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

Background Understory plants represents the largest component of biodiversity in most forest ecosystems and plays a key role in forest functioning. Despite their importance, the influence of overstory-layer composition on understory plant diversity is ...

Genomic Offset Analyses: Mind Your Climate Variables
Recent methods based on genomic offset (GO) statistics aim to quantify the risk of non‐adaptation of populations to future climates. This study assesses how well genomic offset values correspond to population variation in fitness, depending on the methods and climate data used.

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.

Ecology of bryophytes along altitudinal and latitudinal gradients in Chile [PDF]
The bryophyte vegetation in twenty-eight hectare plots in forests of S-Chile between 38° and 42°S and sea level and the forest line has been studied. Since bryophytes are fully dependend on atmospheric water and nutrient supply, they are good indicators ...

Hydrological controls on nutrient exportation from old-growth evergreen rainforests and Eucalyptus nitens plantation in headwater catchments at Southern Chile [PDF]
Soil cover disturbances have a direct effect on biogeochemistry, potentially enhancing nutrient loss, land degradation and associated changes in ecosystem services and livelihood support.

En Magallanes los bosques de lenga aptos para la producción de madera son del orden de 500.000 ha. Desde 1991 los bosques que se intervienen se manejan con cortas de protección. Hasta la fecha se han intervenido cerca de 30.000 ha bajo este sistema. En este trabajo se analiza las modificaciones que se producen en los bosques intervenidos a existencias,

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