Genomic responses to climate: Understanding local adaptation in the Andean tree species Nothofagus pumilio and implications for a changing world

Plants, People, Planet
Societal Impact Statement Forest trees tend to be strongly genetically adapted to their local environments, but climate change will probably subject trees to novel combinations of precipitation, temperature, and photoperiod.

Habitat-specific vegetation and seasonal drivers of bird community structure and function in southern Patagonian forests [PDF]

, 2015
Biodiversity conservation requires knowledge about the factors that influence the structure and function of biotic assemblages. In southern Patagonian Nothofagus forests, birds are the most abundant and diverse vertebrates and are known to have different

How does the silvopastoral use modify the structure and population dynamics of mixed cypress and coihue forests? [PDF]

, 2018
Los bosques mixtos de ciprés de la cordillera (Austrocedrus chilensis) y coihue (Nothofagus dombeyi) del noroeste de la Patagonia están influenciados por fuertes presiones antrópicas como el uso silvopastoril, y en los cuales no existe una planificación ...

Shelterwood cut intensity determines recovery pathways of managed Nothofagus pumilio forests

New Zealand Journal of Forestry Science
Background: Forest harvesting is the main driver of change in forest structure and natural regeneration dynamics during management. Forest recovery after disturbances is important for economic values and ecological processes of natural forests. The aim of the study was to assess recovery paths of Nothofagus pumilio (Poepp.

Tomentella (Thelephorales, Basidiomycota) en bosques de Nothofagaceae de Patagonia, Argentina: micorrizas de nuevas especies

Boletín de la Sociedad Argentina de Botánica, 2017
La presencia de especies de Tomentella ha sido reportada abundantemente en bosques templados, tropicales y regiones circumpolares. Las especies del género Tomentella forman típicamente ectomicorrizas (EM) aunque también micorrizas orquioides, ericoides ...

Seed regeneration in native forests of Nothofagus antarctica under silvopastoral use in Southern Patagonia, Argentina [PDF]

, 2013
The aim of the present study was to evaluate the effect of silvopastoral use in two pure stands of Nothofagus antarctica (ñire, ñirre) growing at two site qualities on the regeneration cycle from production and quality of seeds, and the establishment and

Variable retention forestry conserves habitat of bird species in Patagonian Nothofagus pumilio forests

Annals of Forest Research, 2018
Variable retention is an alternative harvesting system that could be implemented instead the more traditional ones (e.g. shelterwood cut for N. pumilio forests in southern Patagonia), because it was designed not only for timber purpose, but also for conservation.
