Determination of optimal tree height models and calibration designs for Araucaria araucana and Nothofagus pumilio in mixed stands affected to different levels by anthropogenic disturbance in South-Central Chile

Annals of Forest Science, 2023
Key message Here, we present a workflow for determining the optimal tree height model and calibration design for forests affected to varying degrees by anthropogenic disturbance.

First records of three species of Oxycraspedus Kuschel (Coleóptera: Belidae) in Argentina and use of a predictive model to compare their potential distribution with the range of their host-plant, Araucaria araucana Primera cita de las tres especies de Oxycraspedus Kuschel (Coleóptera: Belidae) en Argentina y uso de un modelo predictivo para comparar su distribución potencial con el rango de su planta huésped, la Araucaria araucana

Revista Chilena de Historia Natural, 2007
The first records of the three known species of Oxycraspedus Kuschel (Belidae: Oxycoryninae) in Argentina are reported, and added to their known distribution in Chile.

Comparative Study of the Starch Digestibility of Araucaria angustifolia and Araucaria araucana Seed Flour

Starch - Stärke, 2008
AbstractAraucaria angustifolia and Araucaria araucana are South American conifers; the former grows in southern and south‐eastern Brazil and north‐eastern Argentina and the latter grows in mountainous region of southern Argentina and Chile. The seeds of the conifers have been consumed by the natives for a long time.

Branch whorls of juvenile Araucaria araucana (Molina) Koch: are they formed annually? [PDF]

Revista chilena de historia natural, 2000
El crecimiento de A. araucana, al igual que el de muchas otras coniferas, se caracteriza por la produccion de un fuste monopodico y ramas en verticilos. Sin embargo, en esta especie, no se ha investigado sistematicamente la periodicidad de la formacion de los verticilos.

Resilience beyond expectations: seedling performance under fire and grazing pressure in old-growth Andean Araucaria araucana forests

Frontiers in Forests and Global Change
Altered fire regimes are mainly driven by anthropogenic factors and amplified by climate anomalies globally. Biological legacies that persist after fire are key for the post-fire vegetation recovery, facilitating the establishment and growth of new plant

Inverse effects of soil moisture and litter quality on litter decomposition along a gradient from hyper‐arid to temperate climate

Journal of Ecology, Volume 114, Issue 1, January 2026.
We hypothesized that litter decomposition (H1) and litter quality (H2) increase with increasing soil humidity, therefore litter from the wetter sites to have the highest litter quality and decompose fastest in each site, and fastest on the wet end of the gradient (H3).

Structure and conservation status of Araucaria araucana forest outside the natural reserves of Argentina. The case of the Chiuquilihuín Mapuche community

Revista de la Facultad de Agronomía, 2012
Chiuquilihuín (39° 36´ S and 71° 13´ W, 5,144 ha) is an area of natural grasslands, shrublands and forests, dwelled by 300 native people of the Mapuche ethnic group devoted to extensive cattle ranging, forestry and edible seed gathering.

Structural and Functional Properties of Araucaria araucana and Araucaria angustifolia Seed Proteins as a Plant‐Based Food Source

Sustainable Food Proteins, Volume 3, Issue 4, December 2025.
Morphologically, A. angustifolia seeds were significantly larger, while A. araucana exhibited more regular, triangular shapes. Proximate composition revealed a carbohydrate‐rich profile in both species, with a significantly higher lipid content in A. araucana. Amino acid analysis showed similar profiles, with high levels of aspartic and glutamic acids.

Applying Genomic Offsets to Breeding Programmes: Bridging Evolutionary Insights With Practical Applications

Evolutionary Applications, Volume 18, Issue 10, October 2025.
ABSTRACT As global temperatures rise and become more variable, the capacity of domestic species to adapt, while maintaining production efficiency, is becoming a pressing concern. In this context, genotype‐by‐environment (GxE) interactions pose a significant challenge for selective breeding, as traits that perform well in one environment may not in ...
