Decoupled Climatic Drivers of Tree and Ground-Layer Carbon Uptake in Mountain Ecosystems Around the World. [PDF]
Glob Chang BiolAcross four continents, we investigated how temperature controls the productivity of high mountain vegetation. We found that the productivity of plants growing close to the ground (< 1 m) tends to be controlled by highly localised “microclimate” temperatures, while the productivity of trees was strongly linked to broader‐scale temperatures.

Interannual variations in primary and secondary growth of Nothofagus pumilio and their relationships with climate [PDF]
Trees, 2014 The aim of this study is to evaluate the relationships between primary and secondary growth as well as the influences of climate variations on both types of growth. The relationships between apical (or primary) and radial (or secondary) growth, and climatic influences on both types of growth, were evaluated for Nothofagus pumilio ...

Micropropagación de Nothofagus pumilio (Poepp. et Endl.) Krasser
Bosque, 1997 Nothofagus pumilio is the most important forest species in South Patagonia. The present work was carried out to determine the suitable cultural conditions for in vitro propagation through shoot culture of saplings and a mature tree. The days after sprouting and the presence of the bud scales were critical for culture initiation.

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.
