Origin and Persistence of and (Lycopodiaceae) in Scots Pine Forests.

Understanding the growth dynamics of spore-bearing clonal plant sporophytes and the influence of abiotic and biotic factors is crucial for predicting the persistence of club moss populations and implementing effective habitat management techniques. Despite this, the longevity and development of club-moss populations are rarely studied. This study adopted an integrated approach to assess the probability of repetitive young sporophyte recruitment via sexual propagation in L.

Extensive hybridization in Ranunculus section Batrachium (Ranunculaceae) in rivers of two postglacial landscapes of East Europe.

We demonstrate a wide distribution and abundance of hybrids between the river species Ranunculus aquatilis, R. fluitans and R. kauffmannii with the still water species R.

Genetic Structure of Native Blue Honeysuckle Populations in the Western and Eastern Eurasian Ranges.

Blue honeysuckle ( L.) is a promising berry crop producing edible early-ripening berries with a valuable chemical composition. We evaluated the genetic diversity of native populations from the western (Baltic states) and eastern (the Russian Far East and Japan) edges of the Eurasian range using inter-simple sequence repeat (ISSR) and chloroplast DNA (A-H and L-F) markers.

Soil-surface genotoxicity of military and urban territories in Lithuania, as revealed by Tradescantia bioassays.

The soil surface is a major natural system that accumulates pollutants and allows researchers to disclose the history and the present state of contamination of an area with toxic pollutants. This conclusion is based on the comparison of genotoxicity of aqueous extracts and DMSO extracts of topsoil from military territories in various locations left behind after the retreat of the Soviet Army from Lithuania, and several sites in the city of Vilnius, characterized by different history and current traffic intensity. The specific character of the soil-surface contamination was shown in a series of Tradescantia micronucleus (Trad-MN) and stamen-hair mutation (Trad-SHM) bioassays and tests.
