Levels of allozyme diversity in populations of uncommon Neotropical tree species

摘要: The magnitude of allozyme variation within plant populations is influenced by ecological and life history characteristics the species as well recent population (Brown 1979, Gottlieb 1981, Hamrick & Godt 1989, et al. Loveless 1984). For instance, that have been small for several generations or experienced a series bottlenecks should less genetic than large stable (Karron 1987, Karron 1988, Nei 1975). Tropical forests are characterized high diversity low numbers majority community's (Black 1950, Fedorov 1966). Yet, in most tropical tree communities there with numbers. Thus, it possible to compare levels between common uncommon belonging same community. distribution 16 woody (more four individuals per hectare) has described moist forest Barro Colorado Island, Republic Panama (Hamrick 1987). Levels maintained these trees shrubs varied greatly among but, on average, was relative all temperate 1989). (1989) could, however, find no relationship density diversity. In this paper we measure from mature community Island (BCI). We results analysis those earlier analyses 1987) determine whether sizes BCI significantly more site.
