Using artificial neural networks to explain the attraction of jewel beetles (Coleoptera: Buprestidae) to colored traps

Insect Science, Volume 33, Issue 1, Page 325-335, February 2026.
Jewel beetles can discriminate leaf feeding sites and bark oviposition sites based upon the opponent comparison of their blue, green, and red photoreceptor signals. Through this mechanism, green traps resemble leaves, and purple traps resemble bark, explaining their different attractiveness to males and females.

Water and Communal Conflict: A Review of the Literature

WIREs Water, Volume 13, Issue 1, January/February 2026.
Conceptual summary of the relationship between water access and communal resilience. Following the IPCC, resilience is understood as the capacity to cope with disturbance, responding in ways that maintain systems' essential function, identity, and structure while also maintaining the capacity for adaptation, learning, and transformation.

Unravelling Subsoil Acidification: Mechanisms, Consequences and Remediation

Soil Use and Management, Volume 42, Issue 1, January‐March 2026.
ABSTRACT Subsoil acidification is an intractable agronomic challenge worldwide, and its amelioration is costly and often practically infeasible. Because most studies are confined to the topsoil, acidity development in subsoil commonly remains undetected until it becomes severe.

Toward Co‐Designed Earth System Models: Reflecting End‐User Priorities in Local Applications From a Modeler's Perspective

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Earth System Models (ESM) are crucial for quantifying climate impacts across Earth's interconnected systems and supporting science‐based adaptation and mitigation. However, not including end‐users, especially decision‐makers representing communities vulnerable to climate change, can limit model utility, increase epistemic risks, and lead to ...

Rethinking Global Soil Degradation: Drivers, Impacts, and Solutions

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The increasing threat of soil degradation presents significant challenges to soil health, especially within agroecosystems that are vital for food security, climate regulation, and economic stability. This growing concern arises from intricate interactions between land use practices and climatic conditions, which, if not addressed, could ...

A Global Perspective on River Alkalinity: Drivers and Implications for Coastal Ocean Carbonate Chemistry

Global Biogeochemical Cycles, Volume 39, Issue 11, November 2025.
Abstract The chemical nature of river water significantly influences the coastal carbonate system, contributing to coastal acidification and creating suboptimal conditions for marine calcifiers. While several regional efforts have assessed observationally based riverine concentrations and fluxes of total alkalinity (TA) and dissolved inorganic carbon ...
