Molempien lajien on sopeuduttava ja vastattava toistensa aiheuttamiin valintapaineisiin. Koska vieraslajit ovat monesti uudessa ymp\u00e4rist\u00f6ss\u00e4 voimakkaita kilpailijoita, ja siten vaikuttavat muihin lajeihin sek\u00e4 ymp\u00e4rist\u00f6\u00f6ns\u00e4 voimakkaasti ja jopa haitallisesti, on mahdollista, ett\u00e4 vieraslajin kanssa esiintyviss\u00e4 paikallisissa lajeissa on havaittavissa muutoksia niiden elinkiertopiirteiss\u00e4. Vaikka kilpailun tiedet\u00e4\u00e4n olevan yksi merkitt\u00e4vimpi\u00e4 valintapaineita, tietoa vieraslajien vaikutuksista yksitt\u00e4isiin suomalaisiin lajeihin on v\u00e4h\u00e4n.

Tutkimuksessa, joka tehtiin Jyv\u00e4skyl\u00e4ss\u00e4 kes\u00e4ll\u00e4 2011, mitattiin maastossa 11 tutkimusalueelta koiranputken eri ominaisuuksia (juuri-verso-suhde, maanpinnan yl\u00e4puolisten osien koko, juurien kuivabiomassa, p\u00e4\u00e4- ja pikkusarjojen m\u00e4\u00e4r\u00e4t). Jokaiselta tutkimusalueelta valittiin kaksi kasvustoa, joista toisella kasvoi komealupiinia ja toisella ei. Tutkimuksessa ei havaittu selke\u00e4\u00e4 komealupiinista johtuvaa muutosta koiranputken allokaatiossa, vaan tulokset vaihtelivat paljon alueittain. Lupiinin havaittiin kuitenkin lis\u00e4\u00e4v\u00e4n ep\u00e4suorasti koiranputken korkeutta, lis\u00e4\u00e4m\u00e4ll\u00e4 koiranputkia ymp\u00e4r\u00f6iv\u00e4n kasvuston korkeutta.

Both species have to adapt to changing conditions and respond to selection pressures created by the other. As alien species in the new environments are often strong competitors affecting other species even negatively, it is possible that we might observe changes in life history traits of the local species that are caused by the newcomer. Despite it is known that competition is among the strongest selective forces in nature there is only little information about the effects alien species have on local Finnish species. By studying ecological changes in local species caused by the alien species one can gain valuable conservational information that can be used to estimate and prevent effects of the invasive alien species. In this master's thesis I examined how alien species, lupine (Lupinus polyphyllus), affects the growth allocation and seed weights of cow parsley (Anthriscus sylvestris). The growth allocation study was conducted in Jyv\u00e4skyl\u00e4, Finland in the summer of 2011 by measuring traits of cow parsley from 11 study areas. Within each study area two cow parsley plots, which were relative close to each other, were selected one with and the other without lupine. The growth allocation was measured from 5 cow parsley individuals in each plot. There were no clear directional changes in the growth allocation traits of A. sylvestris (root-shoot ratio, the size of the above ground plant parts, the roots dry biomass, the number of umbels and umbellules) that could be linked to the presence of lupine in the study areas. The results varied greatly between different study areas. However, the lupine increased indirectly the height of the A. sylvestris by increasing the height of the vegetation growths. Overall the regional differences can be explained for example by the length of shared history of lupine and A. sylvestris in particular study area, the point of time when road side management takes place or by the plant community structure and soil microbe differences. Even though lupine is a strong competitor A. sylvestris grows and thrives in same vegetation growths as lupine and no signs of selection pressures created directly by lupine can be observed in the traits of A. sylvestris.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Minttu Sironen (mimisosi) on 2013-09-30 07:58:34.127417.
