| genetic evidence of frequent long-distance recruitment in a vertebrate-dispersed tree. | the importance of dispersal for the maintenance of biodiversity, while long-recognized, has remained unresolved. we used molecular markers to measure effective dispersal in a natural population of the vertebrate-dispersed neotropical tree, simarouba amara (simaroubaceae) by comparing the distances between maternal parents and their offspring and comparing gene movement via seed and pollen in the 50 ha plot of the barro colorado island forest, central panama. in all cases (parent-pair, mother-off ... | 2006 | 16643297 |
| spatial genetic structure of simarouba amara aubl. (simaroubaceae), a dioecious, animal-dispersed neotropical tree, on barro colorado island, panama. | simarouba amara (simaroubaceae) is a vertebrate-dispersed, insect-pollinated neotropical tree found in lowland moist forest from upper mesoamerica to the amazon basin. we assessed the spatial genetic structure of s. amara within the 50-ha forest dynamics plot on barro colorado island in the republic of panama. a total of 300 individuals were genotyped using five microsatellite loci, representing 100 individuals with a dbh>or=10 cm, 100 individuals of 1-10 cm dbh, and 100 individuals of <1 cm dbh ... | 2005 | 16094303 |
| plants as sources of antimalarial drugs, part 6: activities of simarouba amara fruits. | extracts prepared from simarouba amara fruits collected in panama have been found to be active against plasmodium falciparum in vitro and against plasmodium berghei in mice. four active quassinoids have been identified as ailanthinone, 2'-acetylglaucarubinone, glaucarubinone and holacanthone. | 1988 | 3287009 |
