Abstract

COSTA, Leonardo S. da; CORNELEO, Nathana S.  and  STEFENON, Valdir M.. Conservation of Forest Biodiversity: how sample size affects the estimation of genetic parameters. An. Acad. Bras. Ciênc. [online]. 2015, vol.87, n.2, pp.1095-1100.  Epub June 09, 2015. ISSN 1678-2690.  https://doi.org/10.1590/0001-3765201520140064.

Efficient designs are crucial for population genetic studies on forest species. In this study we employed individual based simulations aiming to evaluate what fraction of a population should be sampled to obtain confident estimations of allelic richness and of inbreeding coefficient in population genetic surveys. The simulations suggest that at least 10% of the total population has to be sampled to ensure reliable estimations of allelic richness and inbreeding coefficient. This approach will allow the confidence of the genetic parameters estimations of a larger number of populations, based on a minimal sample within each one.

Keywords : sampling strategy; study design; allelic richness; inbreeding coefficient.
