Abstrakt: The article provides information about a study, which examined seed production and predispersal seed predation in the population dynamics of the shrub Acacia suaveolens. In this study, Seed production and predispersal seed predation in the shrub Acacia suaveolens were examined over 3 consecutive years in eight populations in south-eastern Australia. Seed-crop sizes varied both between and within populations of different ages. Seed production was maximal in the first one to four flowering seasons after establishment, and then declined with plant age. The size of the annual seed-crop was also influenced by rainfall for that year. The study stated that the effects of predispersal seed predation could not be directly related to seedling recruitment.
