Forest Carbon Sequestration Peaks at Intermediate Elevations: Structural and Climatic Drivers of Aboveground Biomass in Bhutan's Temperate Forests

This study reveals that aboveground tree biomass in Bhutan's temperate forests follows a unimodal distribution peaking at mid-elevations (2,000–2,500 m) due to optimal climatic and structural conditions, demonstrating that altitude-dependent drivers necessitate elevation-specific conservation strategies rather than simple linear models for effective climate mitigation.

Climate adaptation and livelihoods: Measuring vulnerability and job creation in India

This paper proposes a dual framework for India's climate adaptation that combines a Livelihoods Vulnerability Index to identify at-risk regions with input-output analysis demonstrating that investing 1.5% of GDP in adaptation measures could simultaneously create jobs for 1.3% of the labor force, thereby addressing both climate resilience and livelihood security.

Geomorphic degradation and heavy metal contamination associated with artisanal alluvial tin and aggregate mining in a Rwandan headwater river

This study demonstrates that artisanal alluvial tin and aggregate mining in Rwanda's Rusine River watershed significantly degrades geomorphological stability and elevates toxic heavy metal concentrations in sediments, causing widespread environmental damage that extends beyond active mining sites through downstream transport.

Climate warming strengthens the effect of silviculture on ecosystem services in uneven-aged mountain forests

Using the Samsara2 simulator, this study demonstrates that climate warming amplifies the productivity and economic efficiency of selective silviculture in uneven-aged mountain forests by intensifying light competition, though these gains often come at the cost of reduced tree-related biodiversity and simplified stand structures.

Marine resources exploitation between Final Pleistocene and Early Holocene (25 – 9 cal kBP). Data from an inland mid-mountain site: Coves de Santa Maira (Valencia region, Spain, Western Mediterranean)

This study analyzes approximately 2,500 fish and mollusk remains from the inland Coves de Santa Maira site to reconstruct human mobility and the significance of marine resource exploitation in the Western Mediterranean during the Final Pleistocene and Early Holocene, while accounting for geological biases and paleogeographic changes.

Variation in Physicochemical Water Quality of Mansagar Lake, Jaipur, Rajasthan, India

A seasonal analysis of Mansagar Lake in Jaipur reveals that summer conditions exhibit the most severe water quality degradation, characterized by high biological oxygen demand and low dissolved oxygen levels caused by organic pollution from sewage and urban runoff, thereby highlighting the urgent need for site-specific management strategies to restore the lake's ecological health.

Develop a methodology for mapping and characterization of salt-affected soils in coastal and inland plains of Gujarat state (India) using remote sensing, field, and laboratory soil studies

This study develops a comprehensive methodology for mapping and characterizing salt-affected soils in Gujarat's coastal and inland plains by integrating multi-temporal remote sensing data, extensive field surveys, and detailed laboratory analyses to delineate spatial distributions, assess chemical properties, and guide reclamation strategies for improved agricultural productivity.

Tree recruitment dynamics over two decades of tropical forest restoration

A two-decade study of tropical forest restoration in Costa Rica reveals that while tree demographic rates converge across different interventions over time, community composition remains distinct from reference forests due to dispersal limitations, highlighting that full ecological recovery requires decades to centuries.
