Spatial variability in herbaceous plant phenology is mostly explained by variability in temperature but also by photoperiod and functional traits.

Whereas temporal variability of plant phenology in response to climate change has already been well studied, the spatial variability of phenology is not well understood. Given that phenological shifts may affect biotic interactions, there is a need to investigate how the variability in environmental factors relates to the spatial variability in herbaceous species' phenology by at the same time considering their functional traits to predict their general and species-specific responses to future climate change. In this project, we analysed phenology records of 148 herbaceous species, which were observed for a single year by the PhenObs network in 15 botanical gardens.

Polyphenols as Potential Geroprotectors.

Currently, a large amount of evidence of beneficial effects of diets enriched with polyphenols on various aspects of health has been accumulated. These phytochemicals have a geroprotective potential slowing down the pathological processes associated with aging and ensuring longevity. In this study, a comprehensive analysis was conducted to determine the adherence of individual polyphenols to geroprotector criteria.

Berberis vulgaris L. extract supplementation exerts regulatory effects on the lifespan and healthspan of Drosophila through its antioxidant activity depending on the sex.

Worldwide the aging population continues to increase, so the concept of healthy longevity medicine has become increasingly significant in modern society. Berberis vulgaris L. fruits serve as a functional food supplement with a high concentration of bioactive compounds, which offer numerous health-promoting benefits.

[The Antioxidant and Geroprotective Properties of an Extract of Mountain Ash (Sorbus aucuparia L.) Fruits].

Plant polyphenols are characterized by a wide range of biological activities, including antioxidant properties, and have a high geroprotective potential. The purpose of this work was to investigate the effect of the extract of rowan berries (Sorbus aucuparia L.) on the lifespan and stress resistance of Drosophila melanogaster with the identification of possible mechanisms of its biological activity.
