Y. Du et al. / Acta Oecologica 39 (2012) 87e93 89Table 1Demographic characteristics of 62 species whose seeds were collected during the 40-month period (T, tree; S, shrub). Dispersers are from Du et al. (2009), and Teng Fang(unpublished data). Pre-/post-seed density is the density of seeds 20 months before and 20 months after the ice storm. Pre-/post-seed limitation, pre-/post-source limitation,and pre-/post-dispersal limitation are the limitation 20 months before and 20 months after the ice storm. IV is the abbreviation of important value. Abundance is the totalindividual number in 24 ha plot. Table was sorted by the pre-seed density.SpeciesLifehistoryDispersersIVrankPre-seeddensity(m 2 )Post-seeddensity(m 2

limited distances from their sourcesand are often dispersed in clumps and because adult trees arethemselves clumped, increasing the number of sites that are veryfar from any sources (Ribbens et al., 1994). Clark et al. (1998)quantify dispersal limitation as1a=n1 source limitationTherefore, dispersal limitation depends not only on dispersalbut also on tree abundance and distribution, and on seed192
