Do marginal plant populations enhance the fitness of larger core units under ongoing climate change? Empirical insights from a rare carnation.

Assisted gene flow (AGF) can restore fitness in small plant populations. Due to climate change, current fitness patterns could vary in the future ecological scenario, as highly performant lineages can undergo maladaptation under the new climatic contexts. Peripheral populations have been argued to represent a potential source of species adaptation against climate change, but experimental evidence is poor.

Essential Oils and Extracts of Sm. and L.: Comparative Phytochemical Composition and Anti-Proliferative and Antioxidant Activities.

In this work, we conducted a comparative phytochemical, chemotaxonomic, and biological study of essential oils (EOs) and extracts (ethyl acetate and methanol) obtained from the leaves of and . The dominant compounds of EO, analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS), are α-pinene, sabinene, manoyl oxide, and germacrene D, whereas α-pinene, limonene, (,)-farnesol, β-pinene, and γ-cadinene are the most representative volatiles of EOs. A multivariate analysis of EOs, included a selection of literature data comparing our samples to samples of // from the Mediterranean area, was performed.

L. from Italy: A Comparative Chemical and Biological Study of Its Essential Oil in the Mediterranean Context.

L. (sage) is one of the most appreciated plants for its plethora of biologically active compounds. The objective of our research was a comparative study, in the Mediterranean context, of chemical composition, anticholinesterases, and antioxidant properties of essential oils (EOs) from sage collected in three areas (S1-S3) of Southern Italy.
