Critical Slowing Down Reveals Hydrologic Resilience Loss Across Amazon Sub‐Basins

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The Amazon's hydroclimate exhibits basin‐scale early‐warning signals of critical slowing down (CSD), a statistical signature of declining resilience as systems approach critical transitions. We apply a multi‐metric framework to precipitation, evapotranspiration, Soil moisture (SM), and extreme streamflows, tracking rolling variance, lag‐1 ...

Integrating Satellite Retrievals, Numerical Models, and Machine Learning for Global Groundwater Recharge Estimation

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Knowledge of the groundwater recharge rate determines whether aquifer use is sustainable. However, accurately measuring recharge globally presents significant challenges due to the complexity of subsurface processes and the lack of direct observational methods.

Initial Estimates of Soil Mercury Emissions Induced by Soil Heating During Global Wildfires

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Wildfires, increasingly frequent extreme events driven by global change, have significantly accelerated the release of mercury (Hg) stored in soils. However, a systematic quantification of Hg emissions from topsoil heating during global wildfires has been lacking.

Lightning‐caused disturbance frequency and severity varies with topography in an Afromontane forest

Journal of Ecology, Volume 114, Issue 3, March 2026.
The results indicate that lightning disturbance severity differs within and among sites, potentially mediated by differences in lightning tolerance among tree species, and provide preliminary support for the hypothesis that disturbance severity declines with disturbance frequency. Abstract Lightning is an important agent of tropical tree mortality, but

Patterns of Tree Species Abundance and Diversity on Urban Sidewalks in Macapá, Amapá, Brazil

Ecological Research, Volume 41, Issue 2, March 2026.
This study presents the first systematic inventory of street trees in Macapá, Northeastern Brazilian Amazon. Results reveal a dominance of exotic and fruit‐bearing species, low tree density, and a replacement of large canopy trees by smaller ones, indicating potential losses in ecosystem services and the need for more biodiversity‐focused afforestation
