· Isolated environments with a low diversity of native species tend to be differentially susceptible to invasion

· Species that are successful invaders tend to be native to continents and to extensive, non-isolated habitats within continents

· Successful invasion is enhanced by similarity in the physical environment between the source and target areas

· Invading nonindigenous species tend to be more successful when native species do not occupy similar niches

· Species that inhabit disturbed environments and those with a history of close association with humans tend to be successful in invading human-modified habitats
