Joly Editeur : Blackwell Science Ltd Année de publication : 2000 Collection : Molecular Ecology num. 9 Importance : pp.1427-1432., 1 ill., 2 tabl., nb réf.

CAESALPINIACEAE ; CHLOROPLAST DIVERSITY ; PCR-RFLP ; SEED DISPERSAL ; TROPICAL FOREST REFUGE ; VOUACAPOUA AMERICANARésumé : The chloroplast genome has been widely used to describe genetic diversity in plant species. Its maternal inheritance in numerous angiosperm species and low mutation rate are suitable characters when inferring historical events such as possible recolonization routes. Here we have studied chloroplast DNA variation using PCR-RFLP (polymerase chain reaction-restriction fragment lenght polymorphism) with seven pairs of primers and four restriction enzymes in 14 populations of Vouacapoua americana (Caesalpiniaceae) a neotropical tree sampled throughout French Guiana. Population diversity (Hs) total gene diversity (Ht) and differentiation among population (Gst) were estimated using Nei's method as 0.09, 0.87 and 0.89, respectively. This is consistent with the limited gene flow associated with synzoochory in this species. The genetic structure observed in the north of French Guiana suggests that historical events such as constractions and recent recolonizations have
had a large impact on the distribution of genetic diversity in this species.Type de document : Tiré à part Permalien de la notice : https://infodoc.agroparistech.fr/index.php?lvl=notice_display&id=151518 Chloroplast diversity in Vouacapoua americana (Caesalpiniaceae), a neotropical fores tree [texte imprimé] / C.

Forêt tropicale humide ; Dissémination des graines ; Guyane française ; AmazonieRésumé : The establishment probabilities, short-term survival, growth rates and biomass allocation patterns of seedlings in two large-seeded tree species, Carapa procera (Meliaceae) and Vouacapoua americana (Caesalpiniaceae), were studied in contrasting microhabitats at Paracou, French Guiana. 2 Seeds (100 per habitat per species) were buried to simulate rodent caches into gap and understorey microhabitats (n = 20 of each) surrounding mature parent trees. The experiment was replicated in Carapa procera (in early March and May) to investigate the effect of temporal variation in seed dispersal on the establishment process. 3 Surviving seeds and sprouting seedlings were repeatedly censused during 2 years after establishment, and the causes of mortality determined. Growth and biomass parameters were calculated for surviving seedlings after 2.5 years. 4 A greater proportion of seeds and germinating seedlings were dug up but less seedlings suffered from damping-off in C.
procera than in V. americana. For both species, short-term survival of seedlings was lower in the understorey where predation by mammals and damping-off occured more frequently than in gaps. 5 Damping off killed more Carapa procera seedlings when buried in Match than in May. whercas mammal predation caused more deaths in May planted seeds. 6 Although survival and growth were enhanced in gaps for both species, seeds and seedlings were much more intolérant to the understorey microhabitat in Carapa procera (almost 100% mortality in shaded habitat) than in Vouacapoua amricana. 7 Seedling biomass allocation was consistent with previous data for large-seeded species but differed markedly between the two study species.
