Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...

Conservation Agriculture Improves Soil Resilience by Integrating Physical, Chemical, and Biological Pathways

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Conservation agriculture significantly enhances soil resilience in tropical agroecosystems, especially in semiarid areas characterized by high degradation susceptibility, mostly related to the occurrence of shallow soils and increasing climate stress.

The Unfolding Desert: Observed Structural Drying and Projected Aridity Risks in a Brazilian Family Farming Citizenship Territory

Land Degradation &Development, Volume 37, Issue 15, Page 10944-10959, September 2026.
ABSTRACT Aridification in Semiarid regions is a recurring theme in Intergovernmental Panel on Climate Change (IPCC) reports and has been documented in Northeastern Brazil. This study analyzes the spatiotemporal dynamics of aridification in the Lower São Francisco River “Citizenship Territory” (Sergipe and Alagoas) at a fine spatial resolution (~1 km ...

Effect of Phosphate Fertilization and Cutting Date Improves Nutritional Status and Productive Parameters of a Tropical Forage Legume

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT The use of chemical fertilizers is economically and environmentally costly to produce and apply. Therefore, optimized fertilizer use is critical to increase or maintain crop yields. We evaluated the productive and nutritional characteristics of the Stylosanthes cv “Campo Grande” submitted to different cutting date and phosphate fertilization ...

Influence of Seasonality on Habitat use and Spatial Distribution Patterns of Tree‐Dwelling Scorpion (Physoctonus debilis) in Brazilian Caatinga

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
Habitat selection plays a crucial role in the survival of various animals, primarily due to their ability to identify suitable sites for development. In Caatinga regions, climate seasonality has a strong effect on vegetation, consequently influencing the occurrence and spatial distribution of diverse plant‐associated organisms.
