Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

Pest Management Science, EarlyView.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

Forest edges buffer effects of agricultural management on bee–plant interaction networks

Ecological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Coinvasional disruptions to island pollinator networks

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Structural Characterization and UVB Irradiation Protective Effect of the Polysaccharide From Tremella fuciformis After Microbial Fermentation

Food Frontiers, Volume 7, Issue 5, September 2026.
ABSTRACT Tremella fuciformis is an edible mushroom rich in bioactive polysaccharides. In this study, T. fuciformis was extracted by citric acid under high temperature and high‐pressure (121°C, 0.1 MPa), followed by fermentation with Saccharomyces cerevisiae CH006 and Thermus thermophilus HB27.

Biochar Production From Invasive Alien Plants: A Pathway to Sustainable Biomass Management and Resource Recovery

Environmental Quality Management, Volume 36, Issue 3, September 2026.
ABSTRACT Across the world, invasive alien plants (IAPs) threaten biodiversity, ecosystem functioning, ecosystem services, and livelihoods. A potentially sustainable method for controlling IAPs is to convert their biomass into biochar, which reduces invasion pressure while producing useful products.
