Disparate responses of above- and belowground properties to soil disturbance by an invasive mammal [PDF]
, 2014 Introduced mammalian herbivores can negatively affect ecosystem structure and function if they introduce a novel disturbance to an ecosystem. For example, belowground foraging herbivores that bioturbate the soil, may alter process rates and community ...

Insect antifeedant compounds from Nothofagus dombeyi and N. pumilio
Phytochemistry, 2004 A bioassay-guided purification of the extracts of Nothofagus dombeyi and N. pumilio leaves yielded several triterpenes and flavonoids including 2-O-acetylmaslinic acid, 3-O-acetyl 20,24,25-trihydroxydammarane, and 3,20,24,25-tetrahydroxydammarane as new natural products.

An ecophysiographic approach for Araucaria araucana regeneration management [PDF]
, 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

Secado artificial de madera de coigiie (Nothofagus dombeyi)
Bosque, 1992 A program of artificial drying of coigue wood (Nothofagus dombeyi) 1 inch thick, pretreated by hot water soaking to 70° C during 48 hours was applied in this research. The specific objectives were to apply a drying program based on moisture content, and to evaluate the drying quality.

Effects of artificial damage on the branching pattern of Nothofagus dombeyi (Nothofagaceae) [PDF]
Annals of Forest Science, 2006 The effects of artificial damage on the branching pattern were studied for a natural population of Nothofagus dombeyi trees. In four independent experiments, leaves, buds, distal internodes and/or nodes were clipped from main-branch shoots. The sizes of shoots close to the site of damage were compared with those of control shoots.
