Baraloto (2001)

See seedlings for a summary.
Appendix A (p.272-281) sums up morphological and environmental characteristics of some tree species, including seed dispersal mode, weight and spreading distance.

Forget (1988)

A long term study was drawn in 1984 about natural regeneration of 8 tree species in French Guiana. These species were chosen because of their diaspore dispersal mode: among Caesalpiniaceae, Eperua falcata (autochory), Eperua grandiflora (barochory), Dicorynia guianensis (anemochory), Vouacapoua americana (synzoochory by rodents), Swartzia longicarpa and S. remiger (synzoochorie by bats); among Myristicaceae, Virola michelii et Virola sp. nov. (endozoochory by arborical mammals and birds). Seed dispersal and surivival were analyzed for the first four species versus the distance from the mother tree. Demographic strucutures for height and population dynamics of seedlings and saplings of all species have been studied close to the mother trees in mature forest plots (2,500 to 8,100 m²) and in windfalls. They have ben compared to tree repartitions. A hypothetical continuum of 8 regeneration modes is proposed, from small-distance dispersed species, very tolerant to shade and with a dense repartition, to widely dispersed species, less tolerant to shade and with a wide dispersion.

Table 51 (p.222) sums up all data including seed weight, dispersion distance and parasistism of 9 species.
