Genetic variation in the vulnerable and endemic Monkey Puzzle tree, detected using RAPDs [PDF]

Heredity, 2002
Araucaria araucana (Monkey Puzzle), a southern South American tree species of exceptional cultural and economic importance, is of conservation concern owing to extensive historical clearance and current human pressures. Random amplified polymorphic DNA (RAPD) markers were used to characterise genetic heterogeneity within and among 13 populations of ...

Araucaria araucana: Monkey Puzzle Tree

EDIS, 2003
Monkey-Puzzletree is a large, bizarre evergreen, 60 to 70 feet tall and 30 to 35 feet wide, which forms a loose, see-through, pyramidal shape with a straight trunk. The tree is so open in habit you could almost look at it and not see it.

Aboveground tree biomass of Araucaria araucana in southern Chile: measurements and multi-objective optimization of biomass models

iForest - Biogeosciences and Forestry, 2021
Estimating carbon stocks in wooded systems is crucial to quantify national greenhouse gas balance estimates. However, inaccurate estimates are likely due to the divergent architecture of many species.

Sustainable and efficient protocols for in vitro germination and antioxidants production from seeds of the endangered species Araucaria araucana

Journal of Genetic Engineering and Biotechnology, 2021
Background The Pehuén or Monkey puzzle tree (Araucaria araucana) is an evergreen coniferous tree, which has been historically used for social, medicinal, and nutritional purposes. We have recently showed the value of A. araucana seeds as a rich source of

A Holocene history of monkey puzzle tree (pehuén) in northernmost Patagonia

Journal of Biogeography, 2020
AbstractAimAlthough it is established that climate and fire have greatly influenced the long‐term ecosystem dynamics of Patagonia south of 40°S, the environmental history from northernmost Patagonia (37–40°S), where endemic and endangered monkey puzzle tree (Araucaria araucana) occurs, is poorly known.

Mountain seeds: gathering, uses and commercialization of seeds of the monkey puzzle tree (Araucaria araucana) by Mapuche-Pewenche communities of the southern Andes

Pirineos: Revista de Ecología de Montaña, 2019
The monkey puzzle tree (Araucaria araucana), or pewen in Mapuche language, is a native tree from Chile and Argentina with a strong cultural importance for Mapuche-Pewenche communities from the southern Andes. Using qualitative methodologies and ethnografic techniques, we assessed the different current uses, and economic and commercial aspects ...
