Spremembe svetlobnih razmer in pritalne vegetacije na območju gozdnega roba bukovih gozdov : magistrsko delo : magistrski študij - 2. stopnja = Changes of light conditions and understory vegetation on forest edge area : M. Sc. Thesis : Master Study ProgrammesBratun, PrimožV magistrski nalogi je preučevano spreminjanje svetlobnih razmer in pritalne vegetacije na gozdnem robu bukovih združb Blechno-Fagetum in Hacquetio-Fagetum. Raziskava je bila izvedena v krajinah Janč ... in Kočevskega roga. V vsaki krajini so bili preučeni 4 transekti. Transekt je sestavljalo 6 ploskev, ki so bile nanizane iz travnika (2) v notranjost gozda (4) na skupni razdalji 80 m. Na vseh ploskvah so bile opraviljene fotografije hemisfere ter izračunani deleži direktne in difuzne svetlobe. Deleži svetlobe so se gibali med 0,999 na travniku in 0,065 v gozdu. Na ploskvah v gozdovih so bili opravljeni fitocenološki popisi. Ugotovljene so bile statistično značilne razlike deležev svetlobe med ploskvami, nenaden upad deležev svetlobe ob prehodu iz travnika v gozd in večja variabilnost deležev direktne svetlobe. Spreminjanje števila vrst in Shannonovega indeksa biotske pestrosti z oddaljevanjem od gozdnega roba v notranjost gozda ni bilo statistično značilno. Ellenbergove fitoindikacijske vrednosti so pokazale razlike med krajinama v kisloljubnosti vrst. Klasifikacija popisov z dendrogramom je pokazala značilne razlike med krajinama vendar ni pokazala podobnosti ploskev z isto oddaljenostjo od gozdnega roba. Ellenbergove fitoindikacijske vrednosti svetlobe niso bile statistično značilno odvisne od izmerjenih deležev svetlobe. Ravno tako ni bila ugotovljena statistično značilna povezava med vrstno pestrostjo in deleži svetlobe ter Shannonovim indeksom in deleži svetlobe. Podatki o svetlobi in pritalni vegetaciji niso nakazovali pasu postopnega spreminjanja %ekotona.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [P.
