Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

open access: yesInsect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Non‐crop habitats and cover crops as potential ecological corridors and stepping stones for autumnal migrating hoverflies

open access: yesInsect Conservation and Diversity, EarlyView.
Mass migration of hoverflies was observed near Prague city in a highly agricultural landscape, representing only the second record of hoverfly migration in the Czech Republic. This rare observation was likely driven by the need to rest, shelter and replenish energy, although most flowers had already finished blooming.

Seasonal effects of land cover and intensity of farming practices on α and β diversity of grassland arthropod communities

open access: yesInsect Conservation and Diversity, EarlyView.
Land cover heterogeneity drives grassland arthropod diversity in spring, while local management intensity becomes the primary driver in autumn, revealing strong seasonal shifts in environmental influences. Landscape‐scale farming intensity significantly shapes arthropod community composition through balanced variation, demonstrating its role as an ...

The multidimensional regulation roles and mechanisms of calcium in fruit quality

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...
