A matrix model for the population dynamics of Hyptis suaveolens, an annual weed
(2009-12-08)Hyptis suaveolens is a neotropical annual weed that invades savanna agricultural systems. Although fire, grazing and soil disturbances have been proposed to cause its local dominance, these factors have not been experimentally ... -
Epizoic polychaetes (annelida: polychaeta) on Crassostrea rhizhophorae (guilding, 1828) from la restinga lagoon, Margarita island, Venezuela
(2009-12-08)Species richness of epizoic polychaetes on the mangrove oyster, Crassostrea rhizophorae (Guilding 1828), was studied. Monthly collections (January-August, 2001) were made. Oysters were separated from mangroves roots by ... -
Reproductive ecology of Psychotria poeppigiana (RUBIACEAE): a comparative analysis between long-styled and short-styled plants
(2009-12-08)We investigate morph-specific patterns in flower morphology, nectar concentration, and foraging behavior of flower visitors in a population of Psychotria poeppigiana (Rubiaceae), a distylous species of secondary forests ...
