A novel ursane triterpene from Rubus swinhoei
, 2001 A novel ursane triterpene, named swinhoeic acid, was isolated from the roots of Rubus swinhoei. Its structure was elucidated as 18, 19-seco, 2 alpha, 3 beta -dihydroxy-19-oxo-urs-11, 13(18)-dien-28-oic acid by means of MS, 1 DNMR and ...

EPPO Bulletin, EarlyView.Abstract The South African citrus thrips, Scirtothrips aurantii Faure, 1929, has been recorded in Italy for the first time. This species was recently reported in Spain and Portugal. Its presence has been confirmed in the major citrus‐growing area of Catania province (Sicily), infesting citrus trees. S. aurantii is currently included in the EPPO A1 List

Insect Conservation and Diversity, EarlyView.Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

To provide pollinator nesting habitat, cut dead perennial stems in their first winter
Insect Conservation and Diversity, EarlyView.Garden management practises need to consider stem‐nesting bees and wasps to avoid destroying active nests and important nesting materials. Volunteers collected samples of dead stems (in situ where they grew) in winter, spring, summer and fall as part of a participatory research project.

Insect Conservation and Diversity, EarlyView.A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

Insect Conservation and Diversity, EarlyView.Revegetated mine tailing storage facilities support pollinator abundance, diversity, richness and evenness comparable to recently logged boreal forest sites. Agronomic and spontaneous revegetation strategies host similar pollinator and Bombus community structures, indicating multiple rehabilitation approaches can effectively restore pollinator habitat.

Journal of Integrative Plant Biology, EarlyView.This review explores how to make staple foods and horticultural crops more nutritious, including how artificial intelligence‐based screening of gene banks helps deploy nutritionally rich germplasm into breeding. Genome editing can help develop crops richer in minerals, vitamins, and health‐promoting compounds, supporting healthier diets and more ...
