Abstract: The aim of this study was to investigate whether there were differences in the genetic variability and rate and velocity of the seed germination produced by Psychotria tenuinervis located at anthropogenic edges, natural edges, and in the forest interior. The populations of P. tenuinervis showed no differences in genetic variability or structure among the three habitats. There was, however, an indication of inbreeding, which was significantly higher in natural edges than in anthropogenic edges and the forest interior. Within-habitat variation was considerable, but there were no differences in seed mass or rate and velocity of germination among the three habitats. These results suggest that seed characteristics were not influenced by the genetic pattern of P. tenuinervis and that other characteristics of the forest fragment, such as gaps, edge age, and type of matrix exert more influence on seed mass and germination than the distance from the edges.
