Population genetics

The population genetics studies genetic variation within and among populations and examines changes in population structure over space and time. Genetic variation of populations is estimated using different types of molecular markers. The assessment of genetic variability of populations provides insight into their adaptability and present evolutionary forces (mutation, gene flow, genetic drift, and natural selection). The population genetics provides knowledge important in animal and plant breeding, biological conservation, pest control.

 

We are studying genetic diversity of populations of hoverflies (Diptera, Syrphidae), second most important insect pollinators in nature. Our recent studies reveal great genetic diversity among allopatric populations and indicated cryptic species diversity. By studying genetic composition of hoverfly populations, we are able to connect populations evolutionary changes with major geological and climatic changes in the past. We identify biodiversity hotspots and determine migration routes. The knowledge we have reached enables the definition of populations and areas of conservation importance.
