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

open access: yesPLoS 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.

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens [PDF]

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

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

open access: yesMolecular Ecology, Volume 34, Issue 21, November 2025.
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]

open access: yesEcology and Evolution, Volume 11, Issue 14, Page 9191-9197, July 2021., 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

Leaf wettability, anatomy and ultra-structure of Nothofagus antarctica and N. betuloides grown under a CO2 enriched atmosphere [PDF]

open access: yesPlant Physiology and Biochemistry, 2023
Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this study, we analysed the wettability, anatomy and ultra-structure of leaves of Nothofagus antarctica (deciduous) and N.

Landscape and microenvironmental conditions influence over regeneration dynamics in old-growth Nothofagus betuloides Southern Patagonian forests [PDF]

open access: yesPlant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2012
Abstract Old-growth forests present a mosaic of different conditions resulting from the natural forest structure of the stands. Nothofagus betuloides forests have high spatial variability in regeneration without a clear correlation with overstory, and could be related to location of the stands in the landscape.

Response of Nothofagus betuloides (Mirb.) Oersted to different thinning intensities in Tierra del Fuego (Argentina). [PDF]

open access: yes, 2002
O setor florestal da Argentina e Chile tem-se desenvolvido principalmente sobre a base do cultivo de espécies exóticas, ocupando, o bosque nativo, um lugar secundário na definição de políticas de investigação e desenvolvimento. Os bosques de Nothofagus conformam a totalidade do recurso madereiro para as serrarias em Tierra del Fuego.

Bosques mixtos de Nothofagus pumilio y N. betuloides: ¿son estables? [PDF]

open access: yes, 2019
Introducción: La variación en la fenología reproductiva de las especies es un mecanismo importante para mantener la coexistencia de las mismas en los bosques mixtos. En estos, el impacto de los factores limitantes (bióticos y abióticos) en el éxito reproductivo podría estar influenciando sobre las proporciones de las especies que los conforman ...
