Genetska diferenciacija avtohtonih populacij smreke (Picea abies (L.) Karst.) v Sloveniji, ugotovljena z analizo izoencimov
Gregor Božič, Monika Konnert, Mitja Zupančič, Hojka Kraigher, Ivan Kreft, 2003, original scientific article

Abstract: Raziskava obravnava genetsko diferenciacijo 22 populacij smreke (Picea abies (L.) Karst.) z njenih naravnih rastišč v Sloveniji in 4 na Hrvaškem z analizo izoencimskih genskih označevalcev. Razlike med populacijami smo ocenili z genetskimi razdaljami po Gregoriusu (1974) za 15 polimorfnih genskih lokusov. Vrednosti genetskih razdalj se gibljejo med 0,021 in 0,073 (v Sloveniji do 0,063). Izoencimska genetska diferenciranost smreke je razmeroma majhna. Rezultati hierarhične klasifikacije nakazujejo geografsko odvisno združevanjepopulacij v dve skupini: alpsko skupino s Trnovskim gozdom in osrednje dinarsko skupino. Skupini se na območju Snežnika tudi prekrivata.

Trace elements and nitrogen content in naturally growing moss Hypnum cupressiforme in urban and peri-urban forests of the Municipality of Ljubljana (Slovenia)
S. Berisha, Mitja Skudnik, Urša Vilhar, M. Saboljević, Saša Zavadlav, Zvonka Jeran, 2017, original scientific article

Abstract: We monitored trace metals and nitrogen using naturally growing moss Hypnum cupressiforme Hedw. in urban and peri-urban forests of the City Municipality of Ljubljana. The aim of this study was to explore the differences in atmospheric deposition of trace metals and nitrogen between urban and peri-urban forests. Samples were collected at a total of 44 sites in urban forests (forests within the motorway ring road) and peri-urban forests (forests outside the motorway ring road). Mosses collected in urban forests showed increased trace metal concentrations compared to samples collected from peri-urban forests. Higher values were significant for As, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Tl and V. Within the motorway ring road, the notable differences in element concentrations between the two urban forests were significant for Cr, Ni and Mo. Factor analysis showed three groups of elements, highlighting the contribution of traffic emissions, individual heating appliances and the resuspension of contaminated soils and dust as the main sources of trace elements in urban forests.
