Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

River Research and Applications, Volume 42, Issue 7, Page 1604-1617, September 2026.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

Significant Decline in Carbon Storage at the Edges of Mangrove Forest

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Quantitative analysis of blue carbon stored in mangrove ecosystems is essential for understanding their role in climate change mitigation. However, the impacts of edge effects in fragmented mangrove forests are often overlooked in large‐scale blue carbon assessments.

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1672-1685, September 2026.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.
