Seed Bank Dynamics in Altitudinal Gradient on an Inselberg in a Nigerian Secondary Forest

K.A. Okunola and S.O. Oke

We studied the germinable soil seed bank along an altitudinal gradient on an Inselberg in a secondary rain forest in Nigeria. We selected three sampling plots at three altitudinal levels (290, 370 and 450 m). We assessed the composition of the established vegetation. We took twenty soil samples (0-15 cm depth) at each plot in dry and rainy seasons and the seed banks composition was determined by greenhouse germination over a 6-months period. The similarity between the composition of the seed bank flora and that of the established vegetation was low throughtout the gradient. Seed bank density and diversity is environment-dependent for most species. At low altitudes, richness is greater and annual species dominate while at higher altitudes richness diminishes and perennial dominates.

The paper gave a well articulated information on the spatial characteristics of vegetation distribution along altitudinal gradient. Found it very useful for my research.
