641. Ophiostomatoid fungi (Ascomycota: Ophiostomataceae) associated with bark beetles and their possible economic impact in forests and timber productionAndreja Nève Repe, Maja Jurc, 2010, original scientific article Abstract: Ophiostomatoid fungi are commercially and economically important group of fungi in forestry and timber production. This group is represented by several genera of Ascomycetes with common morphological characteristics, although withdistinct taxonomy and phylogeny. Several genera of ophiostomatoid fungi have been considered synonymous solely based on morphological similarities as a result of an adaptation to insect dispersal. Ophiostomatoid fungi cause considerable economic losses in the forestry and timber production due to sap stain and vascular wilt diseases. The threat of introduced ophiostomatoid fungi is increasing with the global timber trade and loose control measurements. An overview of the taxonomy, ecology, concept of association (mutualism/symbiosis) and the economic importance of ophiostomatoid fungi are provided.

644. Bibliometrijska analiza Zbornika gozdarstva in lesarstva : 1950-2004Maja Peteh, 2005, original scientific article Abstract: Z bibliometrijskimi metodami je mogoče kvantitativno ovrednotiti značilnosti prispevkov in pridobiti dodatno znanje o raziskovalnem delu avtorjev. V prispevku so prikazani rezultati bibliometrijske analize revije Zbornik gozdarstva in lesarstva, v kateri je bilo zajetih 593 prispevkov, objavljenih od njegovih začetkov v letu 1950 do vključno leta 2004. Analizirano je številočlankov v letu, število avtorjev, citatov, samocitatov ter oprema člankov s preglednicami in slikami. V povprečju je število sodelujočih avtorjev manjše od dveh, večina (68 %) jih prihaja iz treh institucij, ki izdajajo revijo, ženske pa sestavljajo 17 % delež. V povprečju so prispevki pripravljeni s pomočjo 23 virov, od katerih sta 2 samocitata, opremljeni pa sos 3 - 4 preglednicami in 4 - 5 slikami. Prispevki so v 91 % pisani v slovenskem jeziku. Od začetkov izhajanja revije ostaja primarni vir literaturepisan v slovenskem jeziku (34 %), od katerih jih je 24 % objavljenihv samem Zborniku ali Gozdarskem vestniku ali zbirki Strokovna in znanstvena dela. V začetku devetdesetih so kot drugi najpomembnejši jezik literature angleško pisani viri izpodrinili nemške.

645. Windthrow factors - a case study on PokljukaNikica Ogris, Sašo Džeroski, Maja Jurc, 2004, original scientific article Abstract: This paper presents a case study in windthrow. The case study area was 1.7 ha of two forest gaps on the Pokljuka plateau, Slovenia, where strong wind had blown down 44 trees. An additional 44 standing trees closest to the fallen trees were used as a control group for comparative purposes. The following variables were measured for fallen trees: breast diameter, height, crown diameter and height as well, the number and diameter of roots, the volume of the root system, and root rot. Standing trees were measured for breast diameter, height, crown diameter and height, and the number and diameter of roots. The data were analysed using the machine learning methods in the Weka computer program. The most important factors of windthrow in the case study area were: storm wind (speed above 17 m/s), wet shallow soil, and the edges ofthe forest gaps. The results of the case study show that breast diameter, tree height and the presence of root rot can be classified as windthrow factors.

646. Insect pathogens with special reference to pathogens of bark beetles (COL. Solytidae: Ips typographus L.) : preliminary results of isolation of entomopathogenic fungi from two spruce bark beetles in SloveniaMaja Jurc, 2004, original scientific article Abstract: This paper deals with the most important groups of insect pathogens, i.e. viruses, bacteria, fungi, nematodes and protozoans (microsporidia). We describe their basic characteristics, virulence, method of infecting or attackon the host, signs of illnesses in an affected host, pathogen survival in the outside environment, and the use of bioticcontrol of economically damaging insects. Particular importance is placed on bark beetle pathogens, which have been found in natural populations of hosts, particularly in the large spruce bark beetle (Scolytidae: Ips typographus L.). We also present ourexperience in studying entomopathogenic fungi on the species Dryocoetes autographus and Orthotomicus laricis in Slovenia.
