Pollination ecology in the tropical Andes: moving towards a cross‐scale approach

Biological Reviews, Volume 100, Issue 6, Page 2312-2345, December 2025.
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

MioVeg1: A Global Middle Miocene Vegetation Reconstruction for Climate Modeling

Paleoceanography and Paleoclimatology, Volume 40, Issue 11, November 2025.
Abstract Climate models require boundary condition information, such as vegetation and soil distributions because they influence the mean state climate, and feedbacks can significantly influence regional climate and climate sensitivity to CO2 forcing.

Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

Antipode, Volume 57, Issue 6, Page 2213-2240, November 2025.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact

Tracing Human Diversity in South America's Southern Cone: Linguistic, Morphometric, and Genetic Perspectives Explorando la Diversidad Humana en el Cono Sur de América del Sur: Perspectivas Lingüísticas, Morfométricas y Genéticas

American Journal of Biological Anthropology, Volume 187, Issue 3, July 2025.
ABSTRACT Objectives Studying the relationship between biological and cultural diversity can lead to rich insights into human history. South America has been relatively neglected in this kind of work, even though it intriguingly exhibits unexpectedly high biological and cultural diversity.

Species Limits and Hybridization in Andean Leaf‐Eared Mice (Phyllotis)

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Diversification of Phyllotis coincided with mid‐ to late‐Pleistocene climate change. Species delimitation revealed cryptic diversity within several nominal forms. Genomic analyses revealed evidence for introgressive hybridization. ABSTRACT Leaf‐eared mice (genus Phyllotis) are among the most widespread and abundant small mammals in the Andean Altiplano,

The Early Evolution of a Young Normal Fault in the Aysén Fjord, Chile

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Seismic reflection data have been used to investigate the evolution of faults in oil and gas basins for decades and typically image deeply buried faults at low resolution, with biostratigraphic age control to date horizons at scales of 10 Myr.

Parsimonious machine learning for the global mapping of aboveground biomass potential

Ecography, Volume 2025, Issue 7, July 2025.
Advances in computational power and methods, and the widespread availability of remote sensing data have driven the development of machine learning models for estimating global carbon storage. Current models often rely on dozens of predictor variables to estimate aboveground biomass density (AGBD), resulting in accurate but complex models that are ...
