Functional and phylogenetic beta diversity response of nocturnal moth assemblages to land‐use intensity in grasslands and forests

Oikos, EarlyView.
Land‐use intensification is filtering for species, able to cope with anthropogenic landscapes. This was assumed to result in functionally and phylogenetically homogenous communities, but a recent meta‐analysis could not confirm a consistent homogenization response to human pressure and raises open questions.

Long‐term nutrient addition and grazing exclusion determine flower abundance, diversity and community composition in high‐latitude grasslands

Oikos, EarlyView.
The abundance and composition of flowers within plant communities shape the resources available to flower‐visiting insects. However, it remains unclear how nutrient enrichment and changes in grazing impact plant communities and their floral resources, and whether these effects contribute to ongoing pollinator decline. We investigated how the abundance,

Gas Chromatography‐Mass Spectrometry Analysis, Genoprotective, and Antioxidant Potential of Curio radicans (L. f.) P.V. Heath

ChemistryOpen, EarlyView.
The ethyl acetate extract of Curio radicans is found to contain a higher proportion of bioactive compounds (55% vs 30% in the ethanolic extract) by gas chromatography‐mass spectrometry, and it exhibits stronger antioxidant activity in the DPPH assay (75% vs 65% inhibition) as well as clear genoprotective effects against H2O2‐induced DNA damage ...
