Styrene and its natural analogues: accumulation and sustainable production methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

The Effect of Nitrogen and Phosphorus Fertilization on Plant Community Along Chronosequences of Reclaimed and Unreclaimed Postmining Soils After Coal Mining

Land Degradation &Development, EarlyView.
ABSTRACT Nitrogen and phosphorus availability drive plant community composition, productivity, and ecosystem functioning. During succession, nutrient availability typically changes as organic matter accumulates in the soil, influencing both nitrogen and phosphorus pools. We assessed nutrient limitation along postmining chronosequences (10–50 years old),

Common‐garden experimental evaluation of phylogenetic and functional diversity as drivers of plant performance

Oikos, EarlyView.
Biodiversity is known to influence the performance of coexisting species and has been proposed as a management tool to enhance the resilience and functioning of plant communities under drought. However, experimental studies to disentangle the roles of phylogenetic and functional diversity as drivers of plant performance remain extremely scarce.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.
