41. Structure, development and growth of selection forests at the Granata research siteMatej Reščič, Andrej Bončina, 2007, original scientific article Abstract: The Granata research site was established for the study of structure, growth and regeneration of silver fir-European beech single stem selection forest. Three phytocoenological relevés were carried out, all trees ?5 cm diameter at breast height (d.b.h.) were measured by full callipering, tree growth was analysed for sample trees, regeneration of tree species was registered on 63 sampling plots. In addition, historical data from past forest inventories werestudied. In the period from 1952 to 2003, the share of silver fir has decreased from 86% to 26%, the share of Norway spruce increased significantly,whereas the share of beech and sycamore has slightly increased. The current growing stock amounts to 350 m3 ha-1, with large-size diameter trees (d.b.h. ?50 cm) representing 51% of total growing stock. The site is divided into 16 stand patches with significant differences in tree species composition and diameter distribution. Regeneration is sufficient with silver fir prevailing in total number of seedlings (42%). 23% of all seedlings are damaged as a result of game browsing.

42. An overview of alien Diptera in SloveniaMaarten De Groot, 2013, original scientific article Abstract: The nonindigenous Diptera occurring in Slovenia are overviewed based on literature data. In total, 18 species belonging to eight Diptera families are alien to Slovenia. Most of the species originate from North America and continental Asia. The first record of an alien Diptera species (Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae)) was made in 1959, but the bulk of the species were recorded for the first time in the last two decennia. Most of the species were found in the pre-Alpine and sub-Mediterranean regions. The distribution and abundance of the alien Diptera are not fully known, as in most cases only the first observations were published. Most of the species are phytophagous and are known pests in agriculture and forestry. A list of expected nonindigenous Diptera species for Slovenia is given. It is suggested that a monitoring system should be developed in order to understand the population dynamics and the impact of the alien species on the ecosystem and economy.
