摘要
Strong competitive interactions were measured between intraspecific and interspecific nearest-neighbour pairs. In particular, the size and reproductive potential of the annual forb was reduced whenever it established next to the perennial shrub. Despite this effect, more annuals established close to the perennial shrub, presumably as the result of the latter's multiple-stemmed growth habitat which traps soil at its base providing a "safe site' for germination and establishment. -from Authors
