Insect antifeedant compounds from Nothofagus dombeyi and N. pumilio [PDF]

Phytochemistry, 2004
A bioassay-guided purification of the extracts of Nothofagus dombeyi and N. pumilio leaves yielded several triterpenes and flavonoids including 2-O-acetylmaslinic acid, 3-O-acetyl 20,24,25-trihydroxydammarane, and 3,20,24,25-tetrahydroxydammarane as new natural products.

Richness and Density of Birds in Timber Nothofagus pumilio Forests and their Unproductive Associated Environments [PDF]

Biodiversity and Conservation, 2005
Research on forest management impact focuses mainly on timber stands, and leaves out the unproductive forest environments. These stands are spatially mixed with timber forests. The objective was to evaluate richness and density of birds in timber Nothofagus pumilio forests and their unproductive associated environments, and discuss forest management ...

Biomass accumulation in natural Nothofagus pumilio stands Fireland-Chile

Forest Systems, 1995
The aim of this study was to analize the biomass accumulations in two Lenga (Nothofagus pumilio) natural forests, growing at 250 meters above sea level in Tierra del Fuego-Magallanes, Chile. Allometric equations were developed, based on destructive sampling (91 trees) in order to estimate the biomass.

A cost-effective DNA extraction protocol for long-read sequencing in non-model plants. [PDF]

Appl Plant Sci
Abstract Premise Third‐generation sequencing has revolutionized genomics, enabling in‐depth analysis of genome sequence, structure, and epigenetic features. Yet, extracting high‐quality DNA for long‐read sequencing remains a bottleneck—particularly in non‐model plants, such as mature trees growing in natural environments, which often contain abundant ...

Assessing the role of foliar habit on nutrient losses in a sub-Antarctic forest. [PDF]

Ecology
Abstract Biogeochemical cycles drive global biodiversity and plant productivity. In terrestrial ecosystems, nutrient losses through plants' litter are a critical component of these biogeochemical cycles. In forests, nutrient losses are thought to be higher in deciduous angiosperm species than in evergreen conifers.

Complex History of Organellar Introgression in <i>Nothofagus</i> Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection. [PDF]

Ecol Evol
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Recovery of Seed Quality and Germination Success Following Severe Wildfires in <i>Araucaria araucana</i> Forests of the Southern Andes. [PDF]

Ecol Evol
We assessed post‐fire germination of Araucaria araucana in the southern Andes and found that seed viability and germination increased markedly (from 65% to 90%) between 1 and 8 years after a severe wildfire. Improved germination at longer time‐since‐fire reflects a recovery of reproductive capacity in this ecologically and culturally significant ...
