Abstract:	V magistrskem delu smo s pomočjo različnih metod želeli ugotoviti, kje na Dravsko-ptujskem polju v severovzhodni Sloveniji se pojavlja tujerodna rastlinska vrsta navadna vinika Parthenocissus quinquefolia (L.) Planchon, kakšni so morebitni razlogi za njeno pojavljanje, kakšna je stopnja invazije navadne vinike, morebitne negativne posledice na druge rastlinske vrste in kako navadna vinika vpliva na okoliške rastline z alelopatijo. Najprej smo navadno viniko popisovali v gozdnih otokih, ki smo jih za lažjo obdelavo razdelili na 188 popisnih ploskev. Navadno viniko smo zabeležili v 40 gozdnih otokih, skupaj je bilo evidentiranih 323 osebkov navadne vinike. V gozdnih otokih smo zabeležili tudi 18 drugih tujerodnih vrst. Dobljene podatke smo nato s pomočjo programskega orodja R statistično obdelali. S pomočjo regresijskih modelov smo ugotavljali vzročno-posledične povezave med pojavljanjem navadne vinike, njeno debelino, tipom gozdnega otoka, obsegom gozdnega otoka, površino gozdnega otoka in razmerjem med površino in obsegom gozdnega otoka. Z modelom logistične regresije smo potrdili, da na pojavljanje vinike značilno vpliva tip gozda. Na frekvenco vinik na obravnavanem območju ob tipu gozdnega sestoja v gozdnem otoku vplivajo med obravnavanimi prediktorskimi spremenljivkami še obseg, površina in oblika (razmerje obseg/površina) gozdnega otoka. V nasprotju z našimi pričakovanji, da navadna vinika alelopatsko vpliva na sosednje rastline, smo s pomočjo Student-t testa potrdili, da navadna vinika ne vsebuje hlapljivih alelopatskih učinkovin, ki bi vplivale na kaljivost semen navadne vodne kreše (Nasturtium officinale). Vpliv alelopatskih učinkovin navadne vinike v prsti smo statistično dokazali le v neposredni bližini navadne vinike.

Title:	The distribution of invasive Virginia creeper (Parthenocissus quinquefolia (L.) Planchon) in the forest islands between Maribor and Ptuj
Abstract:	In the master's thesis we aimed to reveal the distribution of non-native plant species Virginia creeper Parthenocissus quinquefolia (L.) Planchon in the Drava-Ptuj lowland and to understand the patterns of its occurrence, the degree of invasion and possible adverse effects on other plant species with allelopathy. On the first step we mapped the Virginia creepers in forest woodlots, which were divided into 188 survey plots. Virginia creepers were recorded in 40 out of 188 forest woodlots. In total 323 specimens of Virginia creeper were registered. In the forest woodlots we recorded 18 other non-native species. The data obtained was later statistically processed using the R software tool. By means of regression models, the causal consequential connections between the appearance of Virginia creeper, its thickness, the forest type of the woodlots, the extent and the surface of the forest island and the relationship between the surface area and the extent of the forest island were determined. With the logistic regression model we confirmed that the type of forest significantly affected the presence of Virginia creeper. The frequency of wines in the area under consideration is affected by the predicted variables: the type of forest stand in the forest island, the perimeter, surface area and shape (ratio of the perimeter/area) of the forest island. Contrary to our expectations that Virginia creeper affects adjacent plants allelopathically, we have confirmed with the Student-t test that the Virginia creeper does not contain volatile allelopathic active substances that would affect the germination of seeds of ordinary test watercress (Nasturtium officinale). The influence of allelopathic active ingredients of Virginia creeper in the soil was statistically proven only in the immediate vicinity of the plant.
Keywords:	non-native species, invasive species, Virginia creeper, regression model, allelopathy.
