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 ...

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 ...

A Mosaic of Future Maladaptation Predicted for the Widespread Tree <i>Nothofagus pumilio</i>. [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. Here the Andes

Radial Growth Patterns Associated with Tree Mortality in Nothofagus pumilio Forest [PDF]
Forests, 2019 Tree mortality is a key process in forest dynamics. Despite decades of effort to understand this process, many uncertainties remain. South American broadleaf species are particularly under-represented in global studies on mortality and forest dynamics.

Lake Bacterial Communities in North Patagonian Andes: The Effect of the Nothofagus pumilio Treeline. [PDF]
Microb EcolOne of the most noticeable environmental discontinuities in mountains is the transition that exists in vegetation below and above the treeline. In the North Patagonian Andean lakes (between 900 and 1950 m a.s.l.), we analyzed the bacterial community composition of lakes in relation to surrounding vegetation (erected trees, krummholz belt, and bare ...

Climate and Nothofagus pumilio Establishment at Upper Treelines in the Patagonian Andes [PDF]
Frontiers in Earth Science, 2018 The upper treeline provides a unique opportunity for documenting changes in forest dynamics in the context of current environmental fluctuations. Documenting the response of forests to present environmental changes will be very useful in developing and ...

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 ...

Variable retention harvesting influences belowground plant-fungal interactions of Nothofagus pumilio seedlings in forests of southern Patagonia [PDF]
PeerJ, 2018 Background The post-harvest recovery and sustained productivity of Nothofagus pumilio forests in Tierra del Fuego may be affected by the abundance and composition of ectomycorrhizal fungi (EMF).

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia [PDF]
Ecology and EvolutionSubantarctic Nothofagus forests are the southernmost forests in the world, with negligible atmospheric nitrogen (N) deposition. Most paradigms about the role of ectomycorrhizal (ECM) fungi in N cycling and plant N uptake at high latitudes have been ...
