Pollen morphology of Nothofagus (Nothofagaceae, Fagales) and its phylogenetic significance [PDF]
Nothofagaceae (southern beeches) are a relatively small flowering plant family of trees confined to the Southern Hemisphere. The fossil record of the family is abundant and it has been widely used as a test case for the classic hypothesis that Antarctica,

Morphological and architectural features of young Nothofagus pumilio (Poepp. & Endl.) Krasser (Fagaceae) [PDF]
The morphology and architecture of young Nothofagus pumilio plants growing as understorey and in a cleared area were assessed. Length, number of internodes, presence of branches and apex condition were registered for each growth unit (GU) in the sampled plant. GUs were grouped according to branching order and age of the bearing axis. Understorey plants

Haematocrit, the proportion of blood comprising erythrocytes, is often used as a proxy of individual condition. Nestling haematocrit is influenced by several factors but ambient temperature is generally agreed as a key driver. It is unclear which day(s) in embryonic or nestling development are most influential in determining pre‐fledgling haematocrit ...

Micropropagación de Nothofagus pumilio (Poepp. et Endl.) Krasser
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
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.

índice de sítio diamétrico: um método alternativo para estimar a qualidade do sítio em florestas de Nothofagus obliqua E N. alpina [PDF]
The first step for constructing models of tree growth and yield is site quality assessment. To estimate this attribute, several methodologies are available in which site index (SI) is a standard one.
