Socio-ecological dynamics of Andean treelines in the 21st century

Frontiers in Ecology and Evolution
Andean treelines are sensitive ecotones that are being increasingly threatened by both the climatic and anthropogenic facets of global change. Although they have received substantial scientific focus over the last decades, we still miss a comprehensive ...

Lagged responses in the composition of small mammal communities to a century of climate change

Ecography, Volume 2026, Issue 4, April 2026.
Climate change has widespread effects on the distribution, abundance and behavior of species around the world, leading to the reshuffling of ecological communities. However, it remains unclear whether individual species' range shifts scale up to result in communities whose rate of change lag, lead, or track the rate of climate change. We capitalized on

Environmental heterogeneity and spatial variation mediates plant diversity and ecosystem stability in mountain ecosystems of the Mediterranean Andes

Ecography, Volume 2026, Issue 4, April 2026.
Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...

Breeding seasonality in Charadriiformes on the Andean Altiplano is influenced by rain and possibly flood risk

Ecosphere
The Andean Altiplano in South America represents a remarkable mountain ecosystem with unique wildlife. However, knowledge of breeding ecology for birds inhabiting Andean Altiplano is scarce, relying mostly on anecdotal records, and drivers of breeding ...

Do the Wettest Days Occur Together? A Global Analysis on Disentangling Precipitation Intensity From Seasonal Timing

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Current precipitation analysis focuses on extreme events or total amounts but misses a critical question: when does the majority of precipitation occur during the year? We introduce a framework that separates two fundamental aspects of precipitation patterns: how many of the wettest individual days contribute to annual totals versus what is ...

Seismic Stratigraphy of the Peruvian Forearc Drifts from 3° to 7°S: Identification and Influence of Lower Layers of the Humboldt Current System

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The seafloor morphology and subsurface geometry of a late Neogene contourite drift located along the Peru margin is documented for the first time using multibeam bathymetry, two‐dimensional and three‐dimensional seismic data. Along the margin several submarine canyons incise the shelf and slope.

Institutionalised Indigeneity, State Formation and Crisis: Lessons From the Indio Institucionalizado in Evo Morales' Bolivia

Bulletin of Latin American Research, Volume 45, Issue 2, April 2026.
ABSTRACT This article examines the institutionalisation of indigeneity in Bolivia under the governments of Evo Morales (2006–2019) as a central component of the MAS project of crafting state hegemony. We trace the emergence of what we call the indio institucionalizado from the social mobilisations of the 1990s and 2000s through the Constitutional ...
