Chemodiversity in natural plant populations as a base for biodiversity conservation

Abstract Many biological and related disciplines recognize population as a carrier of species-specific characteristics adapted to habitat requirements. Within a species’ area of distribution, a wide range of biotic and abiotic factors synergistically shape different habitats, and plant populations develop a set of specific features to respond to given environmental conditions. Distinct populations with phenotypic differences determine the ecotypes within the taxon. Similarly, the chemotype is defined as a chemically distinct plant population, according to the composition of secondary metabolites. Many secondary metabolites have pronounced biological activities and implications for human health. With respect to searching for new sources of secondary metabolites with potential health effects, natural populations of plant species attract the substantial attention of researchers because their habitats are highly diverse and unpolluted. Many studies on this subject have confirmed the biological and chemical diversity of natural populations and emphasized the need for the conservation of natural resources.
