Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

Land Degradation &Development, Volume 37, Issue 9, Page 4368-4382, 30 May 2026.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Fault‐Mediated Groundwater‐Surface Water Mixing Amplifies Hydrochemical/Hydrological Dynamics in a Semi‐Arid Volcanic Lake Basin

Hydrological Processes, Volume 40, Issue 5, May 2026.
Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

High Geomagnetic Reversal Frequency During the Middle to Late Ediacaran (∼570 Ma) Constrained by Integrated Magneto‐ and Cyclostratigraphy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Ediacaran–Cambrian (∼635–539 Ma) geomagnetic field is characterized by unusually high reversal rates and markedly weakened field strength. Estimates of these reversal frequencies can reveal key aspects of deep Earth dynamics and their potential influence on surface environments and early complex life.

Climate change and El Niño Southern Oscillation influence on mixing regime and water quality in a deep tropical mountain lake

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Climate change alters lake functioning, water quality, and aquatic biota; yet our understanding of this process is poor for deep tropical mountain lakes. A 15‐yr dataset (2010–2024) from Lake Atitlán, Guatemala, revealed climate change impacts on a tropical lake ecosystem and showed a warming trend of 0.34 ± 0.14°C per decade that intensified ...
