Integrating forest structure and livestock use to assess regeneration and understory responses in Austrocedrus chilensis forests

This study demonstrates that in Argentine Patagonian *Austrocedrus chilensis* forests, livestock grazing negatively impacts tree regeneration and native understory diversity, with these effects varying significantly depending on the forest's structural complexity as defined by a physiognomic framework.

Towards spatio-temporal analysis of global species distribution models

This study introduces a novel, automated framework for global marine species distribution modeling that integrates spatio-temporal barriers and spherical meshes within an INLA-SPDE approach to ensure biologically realistic connectivity, supported by a user-friendly RShiny application and validated through simulations and case studies on Atlantic cod and reef-building corals.

Parcel-Level Deforestation Hazard Rates in the Paraguayan Chaco: A Multi-Scale Empirical Analysis of Annual Clearing Dynamics on Large Cattle Ranches

This paper analyzes parcel-level deforestation dynamics in the Paraguayan Chaco to demonstrate how compressed clearing cycles on active cattle ranches generate high annual hazard rates that, when scaled by the fraction of actively converting parcels, reconcile with broader regional statistics and inform REDD+ baseline calculations.

The Nexus between Energy Access, Climate Variability, and Agricultural Productivity in the East African Community

Using panel data from 2000–2024 across seven East African Community countries, this study demonstrates that electricity access significantly enhances long-term agricultural productivity by enabling improved irrigation and mechanization, thereby positioning rural electrification as a critical strategy for achieving food security and climate adaptation in the region.

Regional thermodynamic constraints on nighttime temperatures during heatwaves: heat retention under humid conditions and stronger cooling under dry conditions

This study reveals that while severe heatwaves consistently elevate nighttime temperatures across Europe, East Asia, Australia, and southern South America, the underlying thermodynamic drivers differ regionally, with humid conditions promoting heat retention in Europe and East Asia while drier conditions facilitate stronger cooling in Australia and southern South America.

Assessment of Fire Distribution across Elevation Zones Using GIS and Remote Sensing On Mount Mulanje, Malawi

This study utilizes GIS and remote sensing to analyze a decade of fire distribution on Mount Mulanje, Malawi, revealing that grasslands are disproportionately affected by fire due to fuel continuity while evergreen and Afro-alpine zones remain resilient, thereby highlighting the need for targeted management strategies at the interface of agricultural and natural vegetation.

Evaluation of Water Quality and Eutrophication Status of Lugo Lake in Northeastern Ethiopia, 2026

This 2026 cross-sectional study evaluated Lugo Lake in northeastern Ethiopia and found it to be in a eutrophic state driven by anthropogenic nutrient enrichment (particularly phosphorus and nitrogen) from agricultural and recreational activities, necessitating immediate conservation and regulatory measures to prevent a shift toward hypertrophy.

Correlation Between Soil Organic Matter and Bulk Density of Terai Soils: A Case Study From Gujara Municipality of Rautahat District, Nepal

This study of Gujara Municipality in Nepal's Terai region reveals that while surface soil organic matter is predominantly low-to-medium and significantly higher than in depleted sub-surface layers, it exhibits no statistically significant correlation with bulk density, indicating that other factors govern soil compaction in these alluvial soils.

Vertical biomass boundaries: Effects of stump exclusion on aboveground biomass comparability and implications for forest-carbon accounting in Nepal

This study quantifies how excluding stump biomass in Nepal's national allometric equations creates a size-dependent underestimation of ground-level aboveground biomass, demonstrating that harmonizing biomass boundaries significantly improves comparability with pantropical models and highlighting the need for explicit boundary definitions in forest-carbon accounting.
