Species both facilitate and compete, and\nthese interactions often span from intra-specific to transcending trophic levels. In a\nplant community species require similar resources, including space, water, light\nand essential elements and compounds. Different strategies governing\ncompetition, growth and survival are used to gain prominence. The intricate\nnetwork formed around facilitative and competitive interactions is, however, easily\ndisturbed by invasive alien species. These harmful species of foreign origin can\nhave serious ramifications on the characteristics and functioning of the community.\nStated by Elton\u2019s hypothesis, high diversity improves resistance against biological\ninvasions, but no scientific consensus on the matter exists. In this modern age of\nbiological invasions, all tools for furthering the goals of conservation biology are\nneeded. This study was conducted to gain an insight into invasive species\ndynamics and specific species prevention. In a greenhouse experiment an\ninvasive vine Calystegia sepium was set against five species of different identities\nfound in Finland. The effects of increasing species diversity on the growth of\nCalystegia sepium were measured. Diversity decreased Calystegia sepium root to\nshoot ratio and its RGR, but to no effect on total dry mass. Competitor identities\naffected different aspects of Calystegia growth. Upon this study can be concluded\nthat biodiversity is a pivotal factor in determining invader performance.
