T\u00e4ss\u00e4 pro gradu -tutkielmassa tutkittiin kokeellisesti vieraslaji komealupiinin (Lupinus polyphyllus Lindley) esiintymisen ja esiintymistiheyden (yksi tai kolme lupiinin kukintoa) vaikutusta alkuper\u00e4islaji hiirenvirnan (Vicia cracca L.) p\u00f6lytt\u00e4j\u00e4-vierailujen m\u00e4\u00e4riin ja siementuottoon kes\u00e4ll\u00e4 2009. Jotta voitiin arvioida mahdollisen kil-pailun tai fasilitaation esiintymist\u00e4, tutkimuksessa selvitettiin my\u00f6s hiirenvirnan ja lupiinin p\u00f6lytt\u00e4j\u00e4lajiston samankaltaisuus, sek\u00e4 se, tarvitsivatko ko. kasvilajit p\u00f6lytt\u00e4j\u00e4n vierailun tuottaakseen siemeni\u00e4. Lupiinin ja hiirenvirnan v\u00e4lill\u00e4 ei havaittu fasilitaatiota tai kilpailua p\u00f6lytt\u00e4jist\u00e4 eik\u00e4 lupiinin esiintyminen tai esiintymistiheyden muutos vaikuttanut hiirenvir-nan siementuottoon, vaikka kasvilajeja p\u00f6lyttiv\u00e4t samat p\u00f6lytt\u00e4j\u00e4ryhm\u00e4t ja niiden siemen-tuotto oli p\u00f6lytt\u00e4j\u00e4rajoittuneista. T\u00e4m\u00e4n tutkimuksen tulosten perusteella voidaankin sanoa, ett\u00e4 esiintyess\u00e4\u00e4n alhaisella tiheydell\u00e4 lupiinin vaikutus hiirenvirnan p\u00f6lytysmenestykseen on v\u00e4h\u00e4inen. Mahdollisena syyn\u00e4 sille, ett\u00e4 p\u00f6lytt\u00e4j\u00e4kilpailua ei lajien v\u00e4lill\u00e4 ollut, voi olla se, ett\u00e4 p\u00f6lytt\u00e4j\u00e4resurssi ei ollut rajallinen tutkimusalueilla tai se, ett\u00e4 lupiinin ja hiirenvir-nan palkitsevuuden ero oli p\u00f6lytt\u00e4jien kannalta v\u00e4h\u00e4inen. On kuitenkin muistettava, ett\u00e4 vieraslajin vaikutus alkuper\u00e4isten kasvilajien p\u00f6lytysmenestykseen on todenn\u00e4k\u00f6isesti laji-kohtaista ja riippuu laajemmasta ekologisesta kontekstista, joka vaihtelee ajallisesti ja pai-kallisesti.", "language": null, "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Mari Kauppinen (masiltal) on 2012-01-25 10:57:49.518272.
