Assessing the dendroclimatic potential of Nothofagus betuloides (Magellan’s beech) forests in the southernmost Chilean Patagonia [PDF]
Trees - Structure and Function, 2018 Tree growth of Nothofagus betuloides forests south of 50°S is affected by local temperature and precipitation together with large-scale high-latitude climate patterns, but also significant influences from the Tropical Pacific were found. The characterization of past climate dynamics in southern South America is difficult due to the shortness of ...

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 ...

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 ...

Biocultural Calendars Across Four Ethnolinguistic Communities in Southwestern South America. [PDF]
Geohealth, 2023 Abstract Since the mid‐20th century, the so‐called Great Acceleration (sensu Steffen et al., 2007, https://doi.org/10.1579/0044-7447(2007)36[614:TAAHNO]2.0.CO;2) has amplified processes of ecosystem degradation, extinction of biological species, displacement of local peoples, losses of languages, and cultural diversity.

Survival rates in the world's southernmost forest bird community. [PDF]
Ecol Evol, 2023 In this article, we describe the temporal dynamics in survival probabilities for the world's southernmost forest bird community and their relationship to climatic variables. We develop a multispecies hierarchical survival model using Bayesian inference to jointly explore age‐dependent survival probabilities at the community and species levels in a ...

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.
