Effects of artificial damage on the branching pattern of Nothofagus dombeyi (Nothofagaceae) [PDF]

open access: yesAnnals 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.

Bud and growth‐unit structure in seedlings and saplings of Nothofagus alpina (Nothofagaceae) [PDF]

open access: yesAmerican Journal of Botany, 2007
In temperate trees, axis length growth generally results from the differentiation of organs at the end of a growing season and the extension of such “preformed organs” in the next growing season. Neoformation, i.e., the simultaneous differentiation and extension of organs, has been studied for only a few species.

Ancient and modern scats record broken ecological interactions and a decline in dietary breadth of the critically endangered kākāpō parrot (Strigops habroptilus)

open access: yesFrontiers in Ecology and Evolution, 2023
Threatened animal taxa are often absent from most of their original habitats, meaning their ecological niche cannot be fully captured by contemporary data alone.

Evidence of chloroplast capture in South American Nothofagus (subgenus Nothofagus, Nothofagaceae)

open access: yesMolecular Phylogenetics and Evolution, 2010
Subgenus Nothofagus, although geographically restricted at present to temperate areas of South America, has captured much attention in discussions of plant biogeography due to its widespread distribution through Gondwanan continents during the Tertiary. However, phylogenetic relationships within the subgenus Nothofagus have not yet been resolved.
