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 ...

Disentangling the Components Shaping Aquatic Richness Over Spatial Scales in Extreme Climatic Events

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Species richness in a region can be partitioned into three components: (1) spatial aggregation of individuals, (2) variation in total individual density and (3) species abundance distribution (SAD). However, it remains unclear how the influence of these components on richness changes under extreme climatic events.

Unprecedented Burning in Tropical Peatlands During the 20th Century Compared to the Previous Two Millennia

Global Change Biology, Volume 32, Issue 3, March 2026.
This study reveals unprecedented burning in tropical peatlands during the 20th century, mainly expressed in the Indomalayan and Australasian regions, emphasising regional variability in peatland burning and its links to modern human activities. Before this period, tropical peatland burning largely followed changes in global temperature and was ...

Effect of land use change on Melolonthidae (Coleoptera: Scarabaeoidea) beetle communities in the deforestation arc of the Brazilian Amazon

Insect Conservation and Diversity, Volume 19, Issue 2, Page 404-419, March 2026.
Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,
