Effect ofHuntiella decorticansand drought onNothofagus dombeyiseedlings [PDF]
AoB PLANTS, 2023 AbstractIn the temperate forests of Patagonia, Argentina, Nothofagus dombeyi, commonly known as Coihue, has shown sensitivity to intense drought events, leading to mortality. Studies have been conducted on Coihue decline and mortality using a variety of approaches, including the role of extreme heat waves and drought, pests and pathogens, particularly ...

Periods of Organogenesis in Shoots of Nothofagus dombeyi (Mirb.) Oersted (Nothofagaceae) [PDF]
Annals of Botany, 2002 The organogenetic cycle of main-branch shoots of Nothofagus dombeyi (Nothofagaceae) was studied. Twelve samples of 52-59 parent shoots were collected from a roadside population between September 1999 and October 2000. Variations over time in the number of nodes of terminal and axillary buds, and the length, diameter and number of leaves of shoots ...

Using Genome-Wide SNP Discovery and Genotyping to Reveal the Main Source of Population Differentiation in Nothofagus dombeyi (Mirb.) Oerst. in Chile [PDF]
International Journal of Genomics, 2016 Within a woody plant species, environmental heterogeneity has the potential to influence the distribution of genetic variation among populations through several evolutionary processes. In some species, a relationship between environmental characteristics

High diversity of fungal ecological groups in Andean-Patagonian Nothofagus forests. [PDF]
PLoS ONE, 2023 Native Andean-Patagonian Nothofagus forests harbour a unique diversity of microorganisms with diverse ecological roles. Although ectomycorrhizal associations constitute an important fragment of the biota associated with these forests, the factors ...

Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection [PDF]
Ecology and Evolution, Volume 16, Issue 6, June 2026.Field 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 ...

Assessing the role of foliar habit on nutrient losses in a sub‐Antarctic forest [PDF]
Ecology, Volume 107, Issue 4, April 2026.Abstract 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.

Functional Diversity and Community Composition of Soil Fungi Associated With Canopy Dieback in Araucaria araucana Forests of Contrasting Edaphic Conditions [PDF]
Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Soil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...

Tree‐Cavity Denning of Güiña (Leopardus guigna) and Breeding Productivity From Camera Trap Records [PDF]
Ecology and Evolution, Volume 15, Issue 9, September 2025.Tree cavities are critical habitats for numerous vertebrate species. We report the first evidence of güiña breeding in a tree cavity, with insights from camera trap surveys in south‐central Chile's temperate forests. These findings enhance our understanding of the species' natural history, breeding behavior, and habitat preferences.
