Analysis of the influece of ungulates on the regeneration of Dinaric fir-beech forests in the research site Trnovec in the Kočevje forest managementregion
Kristjan Jarni, Dušan Robič, Andrej Bončina, 2004, izvirni znanstveni članek

Povzetek: In the period 1970-2000, 152 fenced-in areas were built in the Kočevje Forest Management Region with an aim to protect tree seedlings and saplings from ungulatesć activity and to monitor the influence of roe and red deer on natural regeneration. The average surface area of fenced areas is 0.71 ha. Using the pair comparison technique (fenced vs. unfenced areas), the structureand the composition of the natural regeneration of tree species as well as complete shrub and herb vegetation were analysed in the research site Trnovec. Furthermore, the vegetation was investigated using the Braun-Blanquetmethod. The research results show significant differences between fenced and unfenced areas, both in tree species composition and in theheight structure of the sapling community. In fenced areas the total numberof saplings taller than 50 cm is higher and an increase is also evident in the number of saplings of silver fir Abies alba, sycamore Acer pseudoplatanus, elm Ulmus glabra and other minor tree species. There are also significant differences in species composition and in the abundance of plant species in the herb layer. The results show that natural regeneration of Dinaric fir-beech forests is successful, provided the influence of ungulates is excluded.

Isolation and characterization of essential oils from the cones of Norway spruce (Picea abies Karst.), European larch (Larix decidua Mill.) and Scots pine (Pinus sylvestris L.)
Janja Zule, Vesna Tišler, Andrej Žurej, Niko Torelli, 2003, izvirni znanstveni članek

Povzetek: Preučevana je bila ekstrakcija eteričnih olj iz svežih storžev navadne smreke, rdečega bora in evropskega macesna ter njihova kemijska karakterizacija z metodo plinske kromatografije. Identificirani so različni monoterpeni in določene njihove relativne koncentracije. Ovrednotene so tudi vsebnosti višjih terpenov in podane razlike v kemijski sestavi posameznih eteričnih olj.

Light response of Fagus sylvatica L. and Abies alba Mill. in different categories of forest edge - vertical abundance in two silvicultural systems
Matjaž Čater, Andrej Kobler, 2017, izvirni znanstveni članek

Povzetek: In managed Dinaric montane fir (Abies alba Mill.) and European beech (Fagus sylvatica L.) forests, the light response of young beech and fir in gap microsites was studied during three consecutive growing periods (2009, 2010, and 2011) under controlled environmental conditions in stands of single-tree and irregular shelterwood silvicultural system. According to maximal quantum yield, the different response between species in microsite light categories was evidenced for silver fir on microsites with predominating diffuse light and for beech on microsites with predominating direct light, respectively. Abundance and change of share in microsite light categories was compared over different elevation belts on comparable sites between two silvicultural systems. The share of forest edge area was bigger in the irregular shelterwood system. Change in width of forest edge (20, 30 and 40 m) did not affect the proportion and share of the microsite in both regions of different silvicultural system. Separation of microsite areas between both silvicultural systems, evident in lower elevation belts was not evident in the most conflict and highest elevation zone, while the absolute values of all categories above 700 m in both systems were almost identical, indicating the same, small-scale irregular shelterwood system, known also as the freestyle silvicultural approach.
