Abstract
Examined how the spatial distribution of Poa annua influenced the ability of Senecio vulgaris to establish in experimental plots. The relative effects of slug herbivores, dead individuals of Poa and live individuals of Poa on Senecio establishment were also investigated. Senecio exhibited a higher rate of population growth when planted amidst clumped Poa than when planted amidst a random distribution of Poa, due to increased survival of Senecio seedlings which emerge in areas having a low density of dead Poa. However, herbivores consumed more Senecio seedlings, and intraspecific competition among Senecio seedlings was greater, where the grass was clumped than where it was randomly distributed. -from Author
