Native trees are related to advanced bird breeding phenology and increased reproductive success along an urban gradient. [PDF]

Ecology
Abstract Urban areas are altered from natural landscapes in several ways that can impact wildlife. Birds are widespread in urban areas, and it is well documented that there are phenotypic differences between urban and non‐urban conspecifics. However, little is known about which characteristics of the urban environment are driving differences. We used 9

The Cinderella tree, <i>Quillaja saponaria</i> - A soap story. [PDF]

Plants People Planet
Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

An ecophysiographic approach for Araucaria araucana regeneration management [PDF]

Ciencia e investigación agraria, 2012
Chilean temperate forests are dominated by Nothofagus and Araucaria araucana species. Despite A. araucana not being at imminent risk of extinction, its cultural value and the associated environmental services and landscape goods have an important role for the conservation of this native forest. In some areas, the future conservation of A. araucana is a

Poblaciones de araucaria enana (Araucaria araucana) en la Cordillera de Nahuelbuta, Chile [PDF]

Bosque (Valdivia), 2008
Araucaria araucana (araucaria o pehuen) desarrolla normalmente en su habitat natural un crecimiento arboreo con altura > 20 m. Sin embargo, en 1984, en la cima de la Cordillera de Nahuelbuta se encontraron dos poblaciones enanas. En este trabajo se caracterizo la estructura, composicion y edades de ambas poblaciones de A.

Intraspecific variation in masting across climate gradients is inconsistent with the environmental stress hypothesis. [PDF]

Ecology
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.

Biotransformation of Araucaria araucana lignans: solid-state fermentation with a naturally occurring Pleurotus ostreatus strain

Rodriguésia, 2022
The effects of a naturally occurring Patagonian strain of the white-rot fungus Pleurotus ostreatus on Araucaria araucana wood lignans was evaluated. Lignans of colonized and non-colonized wood shavings and the activity of fungal ligninolytic enzymes were
