Seeds and fruits
Data
Data by species.
Summaries
Thesis summed up in reproductive phenology.
The fruit class of 308 species is in an appendix.
Thesis summed up in vegetative phénology.
Appendix 5 (vol.2, p.53) contains data about anemochore seeds.
See Collinet's groups for the summary.
Table 5.2 (p.142) gave data about dissemination and seed volume of 35 species.
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.
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.
