The overall results are discussed in relation to the taxonomic implications within the sect. Serpyllum. The first part is focused on the nomenclatural and morphological relationships of the nowadays known taxa of the genus Thymus L. to the: (a) polynomials mentioned in the early botanical works of the 16th to 18th century and (b) plant drawings and descriptions included in antiquity herbals, with emphasis on those based on the work of Dioscorides “Materia Medica”. Results suggest that genus Thymus is related with the pre-Linnaean group of polynomials Thymum and Serpyllum as well as the descriptions of the plants “thymos” and “erpyllos” as included in “Materia Medica” recensions. The overall s...

As the majority of European e-infrastructures are initially designed, developed and implemented under externally funded projects over a defined time period, post-project sustainability is often a concern. The final transformation from a project to a sustainable service requires careful planning and should be considered throughout initial project development. During this presentation we will demonstrate, using the Scratchpads (http://scratchpads.eu) example, how a community based support model can efficiently compliment or even replace the existence of a systematic mechanism of grant renewal. Inspired and committed communities can efficiently contribute in maintaining a de-centralised support and developing mechanism. Scratchpads case study shows how a globally distributed network of people, with diverse backgrounds, can undertake the effort of su...

Most of them are valuable primary data generated in the context of small projects mostly by local communities or individual researchers. Local floristic studies, single nomenclatural acts, small taxonomic treatments, morphological and ecological datasets or novel occurrence records constitute the vital building stones in the study of plant biodiversity. However, in the absence of a wider context or due to the time-consuming nature of manuscript writing, these data are rarely published. They remain hidden, constituting a big part of the ‘dark data’ concept. This prevents researchers from taking credit for their work but also deprives the scientific community of re-usable and invaluable data. The taxonomic community needs tools that facilitate and accelerate the process of entering, structuring, curating and publishing biodiversity. In this talk we will demonstrate how the inte...

The results of a discriminant analysis with predefined groups the natural habitat types wherefrom the plants were collected have shown that the oils of both species collected from the dry dwarf-shrub formations of the lowland have a high carvacrol content whereas those collected from the more mesic timber or highland formations have a high thymol content. Furthermore, the results of this study introduce the use of natural habitat unit as a tool for the assessment of essential oil variation.
