High Tree Species Diversity Promotes Thermal Enhancement Response of Microbial Carbon Use Efficiency

Advanced Science, Volume 13, Issue 53, 24 September 2026.
ABSTRACT Predicting soil carbon dynamics under warming is constrained by limited understanding of microbial thermal adaptation, particularly whether microbial carbon use efficiency (CUE) can adapt to warming and how plant diversity modulates this response. Using soils from a natural tree species diversity gradient in a subtropical forest, we combined a

Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...

Ganoderic Acid A Ameliorates Pentylenetetrazol‐Induced Epilepsy in Mice via Activating KCNQ2

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
GA‐A binds and activates KCNQ2, thereby reducing epileptic‐like EEG discharges, the loss and apoptosis of hippocampal neurons, and improving anxiety and depression‐like behavioral changes. In addition, GA‐A inhibits neuroinflammation and alleviates oxidative stress independent of activating KCNQ2.

The Current and Future Distribution Areas of the Rare and Endangered Fern Cibotium barometz (Cibotiaceae) in Guizhou, China, Based on the MaxEnt Model and ArcGIS

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Using MaxEnt and ArcGIS, we modeled the distribution of the endangered medicinal fern Cibotium barometz under current and future climate scenarios (SSP1‐2.6 to SSP5‐8.5). Precipitation of the Driest Quarter (49.9% contribution) was the key determinant, and projections indicate that under the high‐emission pathway (SSP5‐8.5), the high‐suitability ...

Multilevel Impacts of Habitat Fragmentation on Plant Diversity and Structure in Urban Remnant Forests

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study of 30 urban remnant forest patches in Guiyang, China, found that edge habitats displayed greater forest structural metrics but reduced plant diversity linked to the clumpiness of surrounding impervious surfaces, whereas interior diversity suffered from high edge contrast and impervious clumpiness.
