AB  - The Balkan Peninsula acted as a refugium for many steppic species during the Pleistocene, resulting in a high genetic variability, which, in some cases, presents a northward decreasing latitudinal gradient. In the present study, we investigate the genetic diversity of the European ground squirrel (Spermophilus citellus) in its Balkan distribution, sampled comprehensively across its entire distribution in Greece (133 samples from 21 localities). These samples are compared with others from Serbia (54 samples from eight localities) and the available published data from its range in Europe (124 sequences from GenBank). Our results show that the genetic diversity of the Greek and Serbian populations is not correlated with a latitudinal gradient. However, when the entire European range is considered, the model that best fits the genetic variation of the species is based on the ‘centre–periphery’ hypothesis. The founder (centre) populations of the species were most probably situated in south-eastern Bulgaria and European Turkey and underwent rapid expansion post-glacially, during the Holocene, both northwards (Central Europe) and southwards (Greece), as revealed by the decreased genetic diversity and phylogeographical inference analysis in these marginal regions. These results indicate a particular phylogeographical history of a European species and set a baseline for conservation management in its southern populations.

AB  - The volatile compositions of three closely related Hypericum species growing wild on the island of Crete were studied, all belonging to the section Coridium. Hydro-distillation in a modified Clevenger-type apparatus was performed according to the Hellenic Pharmacopoeia in order to obtain the essential oils, which were analyzed by GC-MS. Identification of the compounds was carried out by comparison of MS spectra and retention indices with literature data, as well as by co-chromatography with authentic samples. In total, 123 different compounds were identified and the main compounds were by order of their abundance as follows: H. empetrifolium: α-pinene, germacrene D, β-pinene, E-caryophyllene; H. amblycalyx: β-elemene, β-selinene, α-pinene, E-caryophyllene, α-selinene; H. jovis: trans-calamenene, α-selinene, β-elemene. The chemical results revealed the differences and similarities (qualitative and quantitative) between the studied oils, supporting the hypothesis that essential oils from Hypericum spp. do not serve as chemotaxonomic markers. Moreover, the essential oils were subjected to antimicrobial screening. According to the given results, the essential oils possessed better antifungal and anticandidal activities than antibacterial activities.
