Effects of Mineralogical Inhomogeneity on Aggregate Dust Optical Properties and Lidar Observables

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Dust aerosols comprise irregular grains and aggregates with various mineralogical mixtures. However, most optical models use effective refractive indices to represent particles. This study develops an inhomogeneous aggregate model assigning mineral‐dependent refractive indices to constituent elements and representing global mineral volume ...

Evaluating harvest control rules under recruitment regime shifts: Evidence from static and dynamic reference biomass in the anchovy fishery of the southern Humboldt ecosystem

open access: yesEcological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
Management performance under recruitment variability and regime shifts depends on the interaction between reference points and harvest control rules. Static reference points combined with gradual ramp‐type HCRs reduce overexploitation risk under high uncertainty, whereas dynamic reference points can enhance adaptability to persistent productivity ...

Species Extinction Curves Under Emergent Spatiotemporal Land‐Use Processes and the Role of Protected Areas

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
Dynamic land‐use change reshapes extinction risk by altering where and how converted areas emerge, expand, and merge. Our spatially explicit framework integrates these land‐use dynamics with species geographic ranges and protected‐area implementation. Frequent emergence of spatially dispersed land‐use patches shifts species loss toward later stages of ...

Mosquito population dynamics are shaped by interactions among larval density, temperature, and relative humidity

open access: yesEcology, Volume 107, Issue 10, October 2026.
Abstract Understanding how variation in key abiotic and biotic factors interact at ecologically relevant spatial scales is crucial for predicting population dynamics, distributions, and abundances. This is especially true for vectors that transmit human pathogens.

From a Probabilistic PBEE Framework to Risk‐Targeted Structural Design With Cascading Hazards: Engineering Application for Seismic–Radiological Safety

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 12, Page 3098-3114, 10 October 2026.
ABSTRACT Earthquake‐induced damage of structures can trigger cascading hazards, linking structural performance to nonstructural consequences. In current engineering practice, these two aspects are typically addressed separately, limiting the ability to account for such coupled effects in design.
