Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia [PDF]

Ecology and Evolution
Subantarctic 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 ...

Diversity-Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent. [PDF]

Ecol Evol
We 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.

Tree seedlings respond to both light and soil nutrients in a Patagonian evergreen-deciduous forest. [PDF]

PLoS ONE, 2017
Seedlings of co-occurring species vary in their response to resource availability and this has implications for the conservation and management of forests.

Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem. [PDF]

Mol Ecol
ABSTRACT It is known that phenological changes (i.e., behavioural and sometimes morphological and physiological traits that repeat annually) influence the wildlife gut microbiota. However, it remains largely unknown to what extent geographic variation could modulate the effect that phenology has on wildlife microbiota.

Evidence of endozoochory in upland geese Chloephaga picta and white-bellied seedsnipes Attagis malouinus in sub-Antarctic Chile. [PDF]

Ecol Evol, 2021
Birds are known to act as potential vectors for the exogenous dispersal of bryophyte diaspores. Given the totipotency of vegetative tissue of many bryophytes, birds could also contribute to endozoochorous bryophyte dispersal. We evaluated the role of endozoochory in two herbivorous and sympatric bird species in sub‐Antarctic Chile and hypothesized that
