Permafrost and Periglacial Processes, Volume 36, Issue 1, Page 123-136, January/March 2025.ABSTRACT In semiarid mountain ranges, rock glaciers constitute an important part of the periglacial environment. However, quantitative data on the state of rock glacier activity remain scarce. Here, we derive kinematic information on rock glaciers located in the Valles Calchaquíes region (24–25° S) in Argentina from optical feature tracking in ...

Uncovering the Potential of Carbon Stocks and Nutrients in Livestock Systems in Zamora Chinchipe
Applied and Environmental Soil Science, Volume 2025, Issue 1, 2025.Zamora Chinchipe’s soil supports the biodiversity of its forests, but small farmers also use it for agricultural activities. Unsustainable management of these areas contributes to expanding the agricultural frontier, which generates pressure on ecosystems.

The Sierra Madre Oriental Orocline: Paleomagnetism of the Nazas Province in NE Mexico
Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.Abstract Curved mountain belts are spectacular natural features that contain crucial 3D information about the tectonic evolution of orogenic systems in the absence of other kinematic markers. The Mesozoic units exposed in the Mexican Fold and Thrust Belt in northeastern Mexico show a striking curvature, whose kinematic history has not been studied. The
