Biological invasions present a significant global challenge, resulting in economic losses, increased strain on healthcare systems, and a decline in biodiversity. When species and organisms are introduced into a new environment, they may either adapt or perish. Consequently, alien genotypes and lineages undergo distinct phases, during which invisible and observable changes occur, including fluctuations in population size. These changes primarily depend on the genetic and genomic characteristics of the species, as well as their interactions with both biotic (living) and abiotic (non-living) environmental factors, including ecological and anthropogenic influences. This dynamic ultimately shapes how alien genotypes respond to natural selection. Although the evolution of invasiveness has been recognized for some time, limited information still exists regarding its molecular and genetic mechanisms. The invasive species Heracleum sosnowskyi, which is spreading in Lithuania and significantly affecting local ecosystems, along with its related species Heracleum mantegazzianum, were selected as model organisms. This study aims to explore the genetic structure and variations within the populations of these species. Furthermore, genomic and transcriptome analyses will be performed on both native and invasive genotypes. Conducting such studies is critical for informing effective management and conservation strategies.
