Development of an Araucaria araucana Beer-like Beverage: Process and Product [PDF]

Fermentation, 2021
The seed from the Araucaria araucana (in Spanish, piñon) tree, native to Chile and Argentina, is sold mainly as raw seed. Engineering a process to add value to piñon has the potential to positively impact local indigenous communities with very little ...

First wild boar density data from Araucaria forest in Patagonian Andes [PDF]

PeerJ
As Sus scrofa is an invasive species in South America, it may have a significant impact on biodiversity. Evaluating this threat requires reliable data, and population density can serve as a critical measure.

Recovery of Seed Quality and Germination Success Following Severe Wildfires in Araucaria araucana Forests of the Southern Andes

Ecology and Evolution
Increasing frequency and severity of forest fires is affecting natural ecosystems on a global scale. Temperate forests that have experienced severe wildfires are likely to encounter difficulties to recover and establish new cohorts of plants in the short‐

Antifungal and Antibacterial Activities of Araucaria araucana (Mol.) K. Koch Heartwood Lignans

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 2006
Abstract Five lignans (secoisolariciresinol, pinoresinol, eudesmin, lariciresinol, and lariciresinol-4- methyl ether) were isolated from an MeOH extract from Araucaria araucana (Mol.) K. Koch wood for the first time in this species and their structures determined with spectroscopic methods.

Fragmentation of Araucaria araucana forests in Chile: quantification and correlation with structural variables [PDF]

iForest - Biogeosciences and Forestry, 2016
Landscape fragmentation is one of the main threats to South American temperate forests due to population growth, conversion of native forests to plantations of exotic species and non-sustainable timber harvesting.

Functional Diversity and Community Composition of Soil Fungi Associated With Canopy Dieback in Araucaria araucana Forests of Contrasting Edaphic Conditions. [PDF]

Environ Microbiol Rep
Soil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...

Reproductive patterns in Araucaria araucana forests in the Andean range, Chile

Ecological Processes
Background Araucaria araucana is a mast species that presents a high variability in annual cone production. Researchers have recorded synchronization events in cone production in different populations, which allows the seed production to be concentrated,

A Mosaic of Future Maladaptation Predicted for the Widespread Tree <i>Nothofagus pumilio</i>. [PDF]

Evol Appl
ABSTRACT Nothofagus pumilio, or lenga beech, is a widespread and locally‐adapted tree species endemic to South America's Patagonia region. Its diverse populations span a 2000‐km‐long range in the Andes Mountains, which is already experiencing adverse effects from climate change.

Listening Deeply to Indigenous People: A Collaborative Perspective and Reflection Between a Mapuche Machi and Ecologists. [PDF]

Ecol Evol
Two‐eyed seeing offers a way to see with both Indigenous Traditional Ecological Knowledge and Western ecological sciences. In this collaborative perspective piece between ecologists and a Mapuche spiritual authority (a Machi), we interweave lived experiences and ecological evidence to present the alarming social‐ecological devastation and conflict in ...
