Razširjenost in zastopnanost tujerodnih invazivnih rastlinskih vrst v obrežnem pasu reke Ljubljanice : diplomsko delo - univerzitetni študij = The distribution and representation of alien invasive plant species along the river Ljubljanica : graduation thesis - university studies
Dolšina, Primož
Namen diplomskega dela je raziskati pojavljanje in razporeditev tujerodnih invazivnih vrst ob vodotoku Ljubljanica. Delo je potekalo na terenu, od izvira do izliva v Savo. Območje je bilo razdeljeno ...na skupno 87 različno dolgih odsekov na obeh bregovih. Odseki so oblikovani glede na spreminjanje okoljskih dejavnikov in spremembe v pojavljanju vrst. S pomočjo vprašalnika jeza vsak odsek izdelana ocena stanja okoljskih dejavnikov in invazivnih rastlinskih vrst. S seznama izbranih invazivnih vrst v Sloveniji je popisanih 21 vrst. Najbolj pogoste so vrste Solidago canadensis, Solidago gigantea, Impatiens glandulifera in Fallopia japonica, v vodi pa je pogosta vrsta Elodeacanadensis. Ocenjena je njihovo prisotnost, pojavnost, fenološka faza, življenjska oblika, pogostost in vitalnost. S kanonično korespondenčno analizo je dokazana povezavo med okoljskimi dejavniki in pojavljanjem invazivnih vrst, največ variabilnosti pojasni dinamika reke, oblika struge in raba zemljišča neposredno za obrežnim pasom. Rezultati so predstavljeni grafično in na ordinacijskih diagramih.
