Photosynthetic response to different light intensities and water status of two main Nothofagus species of southern Patagonian forest, Argentina

Journal of Forest Science, 2009
Net photosynthetic rate (A) and stomatal conductance (gs) of leaves of Nothofagus pumilio and N. an-tarctica seedlings were measured at different photosynthetic photon flux densities (PPFDs, 20, 150, 250, 500, 750, 1,000, 1,500 and 2,200 μmol/m2/s) and ...

Relaxed molecular clock provides evidence for long-distance dispersal of Nothofagus (southern beech).

PLoS Biology, 2005
Nothofagus (southern beech), with an 80-million-year-old fossil record, has become iconic as a plant genus whose ancient Gondwanan relationships reach back into the Cretaceous era.

Assessing land surface phenology in Araucaria-Nothofagus forests in Chile with Landsat 8/Sentinel-2 time series

International Journal of Applied Earth Observations and Geoinformation, 2022
The Araucaria-Nothofagus forests are a unique ecosystem in temperate rainforests of Chile and Argentina. They include red-listed species and have a high cultural importance for the ancestral population and thus require continuous monitoring to support ...

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

Molecular 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.

Environmental and climatic changes in central Chilean Patagonia since the Late Glacial (Mallín El Embudo, 44° S) [PDF]

Climate of the Past, 2014
Multi-millennial environmental and climatic changes in central Chilean Patagonia (44–49° S) during the Last Glacial–Interglacial cycle have been of particular interest as changes in the position and strength of the southern westerlies are the major ...

Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest

Integrative Zoology, EarlyView.
Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

Plant Biology, EarlyView.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.

Living in the Mycelial World

Topics in Cognitive Science, EarlyView.
Abstract This manuscript documents a systematic ethnomycological analysis of ethnographic archives. Focusing on texts describing human–fungi interactions, I conduct a global, cross‐cultural review of mushroom use, covering 193 societies worldwide. The study reveals diverse mushroom‐related cultural practices, emphasizing the significance of fungi ...
