Chemical composition and thermal properties of Chilean Araucaria araucana starch

Starch - Stärke, 2015
Starch isolated from Chilean Araucaria araucana seed was characterized as a follow‐up on a previous study. The apparent amylose (AMM) content determined by potentiometric titration was 28%. The chain length distribution profile of amylopectin (AP) showed two peaks at polymerization degrees (DP) of 12 and 43–44.

Intraspecific variation in masting across climate gradients is inconsistent with the environmental stress hypothesis

Ecology, Volume 106, Issue 4, April 2025.
Abstract Year‐to‐year variation in seed crop size (i.e., masting) varies strongly among populations of the same species. Understanding what causes this variation is vital, as masting affects the ability of tree species to regenerate and determines the population dynamics of a wide variety of animals.

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

Novel phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon Gothan reveals close affinity with extant Podocarpaceae (Coniferales)

Journal of Systematics and Evolution, Volume 63, Issue 2, Page 469-478, March 2025.
We perform a phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon to understand the systematic relationship with extant conifers. Data come from four nucleotide regions (trnL‐F, trnK‐matK, rbcL, psbA‐trnH), xylological characters, and biomolecular composition of five extant conifer families and extinct Xenoxylon. Using maximum parsimony in

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.
