En Chile las plantaciones con especies nativas se han realizado principalmente Nothofagus spp. Desde hace unas tres décadas reportan resultados sobre crecimiento en de que general ilustran un alto potencial productivo, especialmente si realiza manejo silvícola oportuno y sitios apropiados. esa línea, este estudio tuvo como objetivo determinar los incrementos diámetro altura N. obliqua alpin...

Results Differences in responses to water deficits between tropical and temperate species appear to reflect differences in climate regimes. In particular, species native to ever-wet rainfall regimes in New Guinea, where water deficits are generally likely to be short-lived, were effective at conserving water by reduced stomatal conductance. In contrast, high-latitude evergreen species on averag...

The Migadopini are a small tribe of Carabidae with 47 species that occur in South America, Australia, and New Zealand, in the sub-Antarctic areas. In South America, most of the genera inhabit areas related to sub-Antartic Nothofagus forest except two monogeneric genera, the Ecuadorian genus Aquilex Moret and the Pampean genus Rhytidognathus Chaudoir. These two genera are geographically isolated...

The evolution of Antarctic climate from a Cretaceous greenhouse into the Neogene icehouse is captured within a rich record of fossil leaves, wood, pollen, and flowers from the Antarctic Peninsula and the Transantarctic Mountains. About 85 million years ago, during the mid-Late Cretaceous, flowering plants thrived in subtropical climates in Antarctica. Analysis of their leaves and flowers, many ...
