Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter in frugivores' foraging decisions, the temporal dynamics of fruit traits might influence interaction outcomes.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Resource windfalls and political sabotage: Evidence from 5.2 million political ads

American Journal of Agricultural Economics, EarlyView.
Abstract We study the role of incentives in inducing sabotage in political contents, vis‐à‐vis natural resource windfalls. The latter induce plausibly exogenous increases in contests' stakes by extending opportunities for policy implementation or private gain upon winning and enhancing incumbent advantage.
