Influence of liquefied and ccb containing liquefied wood on growth of wood decay fungi
No full textThere are high amounts of post-consumed protected waste wood removed from service every year. The residual biocides, including copper, chromium and boron from CCB (Cu, Cr, B) in post-consumed wood that was protected with biocides may cause environmental problems during waste management, for example during land filling. Therefore, the aim of this study was to find out if Cu and Cr in the
processed waste wood, previously treated with CCB, can be re-used as a wood preservative or in coatings made of liquefied wood. Liquefaction of CCB containing waste wood could be as well the first step in the elimination process of metals. So, the optimal conditions for liquefaction of CCB (Cu, Cr and B) containing black poplar (Populus nigra
L.) wood were established and compared with liquefaction
of uncontaminated black poplar wood. The reactants for liquefaction of black poplar wood sawdust were ethylene glycol (EG) and sulphuric acid. It was observed that in the last stages of the liquefaction process, the presence of Cu, Cr and B did not have any influence on liquefaction yield (LY), while their influence was observed in first stages of the solvolytic reaction. Investigations of fungicidal properties of uncontaminated and CCB containing liquefied wood showed higher antifungal efficacy of liquefied wood without Cu, Cr and B than of liquefied wood that contained CCB. In the tested concentration range, the presence of Cu even promoted the growth of selected wood decay fungi. One of the reasons for higher toxicity of liquefied black poplar sawdust without Cu, Cr and B, was its very low pH value
Landscape changes in the Pivka area, Slovenia
No full textSpontaneous afforestation is one of the biosystemic landscape change processes affecting landscape functioning. The process of overgrowing is highly dynamic,
and the temporal dimension of changes in landscape structure can be of key importance for evaluating habitat suitability.
A detailed study was carried out in the area of 19.52 km2 within the Pivka municipality, where land use is a mixture of traditional farmland, forests, and
extended areas of abandoned former farmland with natural re-growth. In addition, this area is highly important for two bird species: the Barred Warbler (Sylvia
nisoria) and the Red-backed Shrike (Lanius collurio). Both species are sensitive to forest spreading and prefer a mixture of extensive meadows with shrubs and
hedgerows as their most suitable habitat.
Digital BW orthophotos from the 1975 – 2000 period and colour digital orthophotos from 2009 have been used for on screen digitizing of the EUNIS habitat
classes. Indicators of landscape changes were derived from temporal based difference in the landscape structure (different structural indicators based on patch
size, shape, distances and patch dynamics). All the details obtained were evaluated based on Earth observation data and GIS supported methods.
The most valuable parts of the area for both species are, from a biodiversity point of view, the core forest areas and mixture of meadows with shrubs and
hedgerows
Reproductive potential of Roe Deer (Capreolus capreolus L.): review of the most important influential factors
No full textEuropean roe deer (Capreolus capreolus L.) is the most important game-management species not only in Slovenia but also in other
European countries. For effective game management it is crucial to have an understanding of the ecology and population parameters
that shape the population dynamics of the species. Knowledge about the variability of its reproductive potential, i.e. the proportion
of fertilized females, litter size and fawn sex ratio, apart from the parameters that are already in use, would be very beneficial for
methods of control as it could lead to more efficient adaptive game management, including proper planning of culling measures.
Factors affecting the reproductive potential of roe deer include individual (particularly maternal phenotype, i.e. body size, body
mass, physical condition), population (e.g. population density, demographic structure, social stress, genetics) and environmental
characteristics (habitat quality, weather conditions, interspecific interactions, etc.). The final output of reproductive potential is the
sum of all influencing factors and several combinations between them and therefore varies among different populations and environments.
Higher densities can lower roe deer fertility rates and furthermore number of fawns per doe. Litter size is influenced by
doe’s body mass, as heavier females have more fawns in a litter. There are some contradictory findings in studies of sex ratio variation
in connection to female body mass. Litter size can also be influenced by age of does, as primiparous females have smaller litters
than adults, but also decreases with animal senescence. Roe deer populations from northern environments (Scandinavia) have
higher body masses and larger litters than those from the south (e.g. Italy, Spain), which shows the importance of environment for
roe deer reproduction. However, in Slovenia this issue has been neglected until now. In the following report we present an overview
of the recent European research on factors affecting the fertility and reproductive potential of roe deer. Similar research in Slovenia
would also be valuable, as roe deer is exposed to various environmental factors in this area. In addition, it is also involved in unique
interspecific interactions that have not been studied in recent foreign research. Furthermore, Slovene distinguishing databases provide
an outstanding platform for proficient understanding of different effects on roe deer yield in Central Europe

White paper II: costs and benefits of policies and practices addressing land degradation and drought in the drylands
No full textVisibility review of articles published in “Zbornik gozdarstva in lesarstva” in the Web of Science databases
No full textThe article presents a citation analysis of articles published in the journal Zbornik gozdarstva in lesarstva in the database Web
of Science (WoS) throughout the journal’s existence, including the year 2011; citations were obtained in February 2013. Journal
is not indexed in WoS, therefore, the analysis is focused on citations in journals that are indexed in the database. The purpose
of the analysis is to assess the visibility of the journal’s articles in science, which is important for the purpose of evaluating
research performance and for the journal’s editorial policy in the future. From its establishment in 1957 (in 1973 the current
title was introduced, while prior to that year the title had been changed twice) and until 2011, which was the last year included
in the research, 738 articles were published in the journal. 161 (21.8%) of the articles have been cited 267 times in journals
that are indexed in WoS. On average, each cited journal has been cited 1.7 times. 34.6% of citations were done by non-Slovene
authors. Citations in the database WoS can be found under 21 different variations of the journal’s title, which indicates many
inconsistencies. Citations of the articles published in Zbornik gozdarstva in lesarstva can be found in 76 different journals,which are classified in 32 different WoS categories; only one third of them is not in any of the three major categories: forestry
(37.7%), botany (17.5%) and environmental sciences (10.4%). Inclusion of the journal Zbornik gozdarstva in lesarstva into WoS database, combined with the provision of open access, would probably improve its international visibility
