Deformacion compresiva cuaternaria en la Cordillera Principal de Chile central (Cajon del Maipo, este de Santiago).Quaternary compressional deformation in the Main Cordillera of Central Chile (Cajon del Maipo, east of Santiago).

Andean Geology, 2008
A detailed study of recent sediments in the Maipo River Valley (Cajon del Maipo), east of Santiago, shows a compressive deformation documented by coeval reverse faults and drag-folds. These structures are characteristic of a principal stress direction trending roughly N-S (N338 degrees E) that also affects the older sediments of the Abanico Formation ...

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

Journal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Amidst (waste) abundance: world‐making and struggles in hosting a municipal landfill in the Bolivian lowlands Au milieu de l'abondance (de déchets) : fabrication du monde et luttes liées à la gestion d'une décharge municipale dans les basses terres de Bolivie

Journal of the Royal Anthropological Institute, EarlyView.
In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

A Predictive Model for the Anisotropy Index of Semi-Coke Derived from the Properties of Colombia's Eastern Cordillera Coals

Ingeniería y Ciencia, 2020
This study developed a theoretical model for the determination of the Coke Anisotropy Quotient (CAQ) of semi-coke from the properties of its precursor coal.

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, EarlyView.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

Rol del clima y la tectónica en la evolución geomorfológica de los Andes Semiáridos chilenos entre los 27-32°S Role of climate and tectonics in the geomorphologic evolution of the Semiarid Chilean Andes between 27-32°S

Andean Geology, 2013
Un análisis morfométrico que considera la pendiente topográfica y la hipsometría, evidencia las diferencias longitudinales y latitudinales en el grado de madurez del relieve de la región andina entre los 27-32°S.

Regional electrical structure of the Andean subduction zone in central Chile (35°–36°S) using magnetotellurics

Earth, Planets and Space, 2017
A profile of broadband magnetotelluric stations was acquired between 2009 and 2016 at 35°–36°S in the Southern Volcanic Zone of the Chilean Andes to image the subduction zone and its relation with the volcanic arc at this latitude.

Impact of global change on the distribution of mountain mammals and birds

Conservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...
