Negative frequency-dependent selection through variations in seedling fitness due to genetic differentiation of parents' pair in a tropical rainforest tree, Rubroshorea curtisii (Dipterocarpaceae).

ABSTRACT:

Introduction

The role of syngameons in adaption to microgeographical environmental heterogeneity is important and could be one of the sources of rich species diversity in tropical forests. In addition, negative frequency- or density-dependent selection is one of the major processes contributing to the maintenance of genetic diversity.

Methods

To assess genetic factors that affect the fitness of seedlings of Rubroshorea curtisii, a dominant canopy tree species in hill dipterocarp forests, the inter- and intra-population genetic structure of individuals from natural populations and individuals at two permanent plots in a hill dipterocarp forest with reproductive stage was studied. Further, a total of 460 seedlings derived from six mother trees in the plot were raised in
