Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Aims. The paper summarizes the results of population genetic studies of two rare species of the Ukrainian flora in order
to identify factors that may affect the changes in the genetic diversity of populations caused by the reduction in the size
and habitat fragmentation. Methods. Molecular genetic analysis using various types of dominant PCR markers, statistical
methods for genetic data analysis. Results. It was found that, in perennials, genetic effects of habitat fragmentation and
reduction in population size may remain indiscernible for some time. Reduced size in conditions of long-term isolation
leads to a steady decline in intra-population variation and increasing divergence of the populations. Conclusion. When
interpreting the results of the evaluation of the genetic diversity of rare plant species, it is important to consider lifehistory traits of the species and the history of populations.
Keywords: genetic diversity, habitat fragmentation, rare species. |
