Biocultural Calendars Across Four Ethnolinguistic Communities in Southwestern South America

Description: Article describes how, since the mid-20th century, the so-called Great Acceleration has amplified processes of ecosystem degradation, extinction of biological species, displacement of local peoples, losses of languages, and cultural diversity. The authors examine cultural practices and socio-environmental changes across four contrasting ethnolinguistic communities in southwestern South America, from southern to northern Chile along a marked climatic gradient to show the broad application of the… more

Nest-site selection and breeding success of passerines in the world’s southernmost forests

Description: This article studies the nest-site selection and survival rate of the five most abundant open-cup forest-dwelling passerines (Elaenia albiceps, Zonotrichia capensis, Phrygilus patagonicus, Turdus falcklandii, and Anairetes parulus) in the world’s southernmost forests of Navarino Island, in the Cape Horn Biosphere reserve, Chile (55°S).

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile

Description: This article evaluates the role of endozoochory in herbivorous and sympatric bird species in sub-Antarctic Chile. The authors hypothesize that fragments of bryophyte gametophytes retrieved from their feces are viable and capable of regenerating new plant tissue. This relationship may have important implications in the way bryophytes disperse and colonize habitats facing climate change.

Improved Campephiline detection: An experiment conducted with the Magellanic Woodpecker

Description: Article describes a study which tried to determine which of three methods (useing a drumming device to simulate a double‐knock (i.e., territorial acoustical signal), broadcasting a territorial call, or passively listening) best results in a detection of Magellanic Woodpeckers (Campephilus magellanicus ), and if weather variables influence detection probability.

Survival rates in the world's southernmost forest bird community

Description: Article asserts that the Magellanic sub-Antarctic Forest is home to the world's southernmost avian community and is the only Southern Hemisphere analogue to Northern Hemisphere temperate forests at this latitude. Authors describe annual survival patterns and their association with climate variables using a 20-year mark–recapture data set of five forest bird species in the Cape Horn Biosphere Reserve.

The Subantarctic Rayadito (Aphrastura subantarctica), a new bird species on the southernmost islands of the Americas

Description: Article describes a new taxon of terrestrial bird of the genus Aphrastura (rayaditos) inhabiting the Diego Ramírez Archipelago, the southernmost point of the American continent. The authors state that the discovery of this endemic passerine highlights the need to monitor and conserve this still-pristine archipelago devoid of exotic species, which is now protected by the recently created Diego Ramírez Islands-Drake Passage Marine Park.
