Deciphering the transcriptomic regulation of heat stress responses in Nothofagus pumilio. [PDF]
PLoS ONE, 2021 Global warming is predicted to exert negative impacts on plant growth due to the damaging effect of high temperatures on plant physiology. Revealing the genetic architecture underlying the heat stress response is therefore crucial for the development of ...

Restricted Dispersal in the Late Successional Forest Tree Species Nothofagus Pumilio: Consequences Under Global Change [PDF]
Ecology and EvolutionPlants rely on gamete dispersal to ensure the inheritance of their genes. Gene flow, mediated by pollen and seed dispersal, also fosters species' cohesion across space, facilitates population migration, and influences local adaptation. Nothofagus pumilio

A Mosaic of Future Maladaptation Predicted for the Widespread Tree Nothofagus pumilio [PDF]
Evol ApplABSTRACT Nothofagus pumilio, or lenga beech, is a widespread and locally‐adapted tree species endemic to South America's Patagonia region. Its diverse populations span a 2000‐km‐long range in the Andes Mountains, which is already experiencing adverse effects from climate change.

Phytochemical Screening and Antioxidant Activity of Seven Native Species Growing in the Forests of Southern Chilean Patagonia [PDF]
Molecules, 2021 The genus Nothofagus is one of the most abundant in the subantarctic Patagonian forests. Five species inhabit these ecosystems, three evergreen (Nothofagus betuloides, Nothofagus dombeyi, and Nothofagus nitida) and two deciduous (Nothofagus pumilio and ...

Assessing the role of foliar habit on nutrient losses in a sub-Antarctic forest. [PDF]
EcologyAbstract Biogeochemical cycles drive global biodiversity and plant productivity. In terrestrial ecosystems, nutrient losses through plants' litter are a critical component of these biogeochemical cycles. In forests, nutrient losses are thought to be higher in deciduous angiosperm species than in evergreen conifers.

Complex History of Organellar Introgression in <i>Nothofagus</i> Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection. [PDF]
Ecol EvolField photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Diversity-Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent. [PDF]
Ecol EvolWe investigated diversity patterns of vascular plants of overstorey and understorey vegetation separately per stratum and the influence of anthropogenic disturbances along two elevational transects with contrasting slope aspects in a temperate rainforest and alpine scrub in southern Chile.

Detecting Nothofagus pumilio Growth Reductions Induced by Past Spring Frosts at the Northern Patagonian Andes [PDF]
Frontiers in Plant Science, 2019 Extreme climatic events, such as late frosts in spring during leaf flush, have considerable impacts on the radial growth of temperate broadleaf trees. Albeit, all broadleaved species are potentially vulnerable, damage depends on the particularities of ...

The Southernmost Known Population of the Monito Del Monte, Dromiciops gliroides [PDF]
Ecol EvolA range extension for a relict south American marsupial. ABSTRACT The monito del monte (genus Dromiciops) is a small arboreal marsupial endemic to the temperate rainforests of southern South America, and the sole extant representative of the order Microbiotheria. This lineage, considered a sister group of Australian marsupials, is of great evolutionary,
