Differential effects of agricultural expansion on wild bee taxonomic and functional diversity

Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Global determinants of home range sizes in felids: Evidence of human disturbance impact

Journal of Animal Ecology, Volume 95, Issue 4, Page 697-711, April 2026.
This study is the first to demonstrate the influence of anthropogenic factors and species richness in felids on home range size across the entire felid taxon. Felids are a taxon of major interest in conservation biology, and gaining a comprehensive view of their spatial ecology will help derive global conservation recommendations.

The Hepatic Steatosis Diagnostic Performance Using Attenuation Imaging With the Magnetic Resonance Imaging‐Based Proton Density Fat Fraction as the Reference Standard: A Large, Prospective, Multicenter Cohort Study in Japan

Hepatology Research, Volume 56, Issue 4, Page 457-466, April 2026.
In a multicenter cohort of 1059 patients, attenuation imaging (ATI) showed good diagnostic performance and strong correlation with MRI‐PDFF, supporting its value as a noninvasive method for evaluating hepatic steatosis. ABSTRACT Background Attenuation imaging (ATI) is used for the noninvasive diagnosis of hepatic steatosis (HS) based on the ultrasound ...

Agents' Behavior and Interest Rate Model Optimization in DeFi Lending

Mathematical Finance, Volume 36, Issue 2, Page 374-396, April 2026.
ABSTRACT Contrasting sharply with traditional money, bond, and bond futures markets, where interest rates emerge organically from participant interactions, DeFi lending platforms employ rule‐based interest rates that are algorithmically set. Thus, the selection of an effective interest rate model (IRM) is paramount for the success of a lending protocol.

Macroscopic Market Making Games

Mathematical Finance, Volume 36, Issue 2, Page 352-373, April 2026.
ABSTRACT Building on the macroscopic market making framework as a control problem, this paper investigates its extension to stochastic games. In the context of price competition, each agent is benchmarked against the best quote offered by the others. We begin with the linear case.
