a genetic evaluation of seed dispersal in the neotropical tree jacaranda copaia (bignoniaceae).	seed dispersal is a critical but poorly understood life-history stage of plants. here we use a genetic approach to describe seed dispersal patterns accurately in a natural population of the neotropical tree species jacaranda copaia (bignoniaceae). we used microsatellite genotypes from maternally derived tissue on the diaspore to identify which individual of all possible adult trees in the population was the true source of a given seed collected after it dispersed. wind-dispersed seeds were captu ...	2005	16224720
demographic spatial genetic structure of the neotropical tree, jacaranda copaia.	we used genotypes from six microsatellite loci and demographic data from a large mapped forest plot to study changes in spatial genetic structure across demographic stages, from seed rain to seedlings, juveniles, and adult diameter classes in the neotropical tree, jacaranda copaia. in pairwise comparisons of genetic differentiation among demographic classes, only seedlings were significantly differentiated from the other diameter classes; f(st) values ranged from 0.006 to 0.009. furthermore, onl ...	2006	16968265
neighbourhood density and genetic relatedness interact to determine fruit set and abortion rates in a continuous tropical tree population.	tropical trees may show positive density dependence in fruit set and maturation due to pollen limitation in low-density populations. however, pollen from closely related individuals in the local neighbourhood might reduce fruit set or increase fruit abortion in self-incompatible tree species. we investigated the role of neighbourhood density and genetic relatedness on individual fruit set and abortion in the neotropical tree jacaranda copaia in a large forest plot in central panama. using nested ...	2008	18713714
