Ecological theory suggests that interspecific interactions arising between an alien species and native species hold the key to invasion success by an alien species. The well-known hypothesis that an alien species that has few natural enemies is more likely to be a successful invader (e.g., Blossey and Notzold 1995, Mitchell and Power 2003) implies the importance of a trophic interaction. The hypothesis that a community with higher species richness is more resistant to a biological invasion (Stachowicz et al. 1999, Kennedy et al. 2002) is strongly based on the competition theory (Tilman 1982). Further, the way through which a biological invasion affects the local community is an alien-native interspecific interaction such as resource competition, trophic interaction and allelopathy. The important role of interspecific interactions in a biological invasion suggests the detailed evaluation of the interspecific interactions between alien and native species as an interesting approach to the biological invasion issues.
