Determining the genetic population structure and intraspecific evolution of species is important for efficient management. Here we investigated 394 sequences of the mtDNA cyt b of the critically endangered European eel, Anguilla anguilla. We found 62 different haplotypes, among which 32 novel ones. All those sequences were grouped into 9 haplogroup...

Sequence variation of the mtDNA D-loop region was analyzed in order to investigate the intraspecific evolution and the population genetic structure of the critically endangered European eel Anguilla anguilla. An additional attempt was made to collect information on the genetic characteristics of groups of eels representing naturally recruited eels...

The complex life cycle of the European eel predestines unique formation of the population genetic structure. The sweepstakes reproductive success and the chaotic genetic patchiness are the characteristics of this species and its population genetic structure could be described as a genetic mosaic, whose formation is predetermined by the reproductive...

To collect information on possible impacts of a nuclear power plant on the formation of the genetic structure of the population of perch as an intensively exploited fish species, an investigation into the scope of intraspecific genetic diversity of a rapidly changing mtDNA D-loop region of perch was initiated. We determined the partial D-loop seque...

In order to collect information about the impact of Nuclear Power Plants (NPP) on the formation of the genetic structure of the population of commercially exploited fish species, our research group initiated an investigation into the genetic diversity of a rapidly changing mtDNA D-loop region of the perch (Perca fluviatilis). The perch is a natural...

One of the most abundant fish species, Rutilus rutilus, is widely distributed in Lithuania and its potential to adapt to environmental changes attracted our interest. Unfortunately, it is not properly understood how anthropogenic activities can affect the genetic diversity within this species. We studied three populations of roaches (samples collec...

Simple Summary This study concerns evaluation of the possible negative effects of power plants as one of the most important objects generating environmental pollution in aquatic ecosystems. We attempted to research the intraspecific genetic diversity of a naturally distributed fish species, Eurasian perch, based on a comparison of its mitochondrial...

Studies on genetic diversity require biological material containing a reliable source of DNA that can be extracted and analyzed. Recently, non-invasive sampling has become a preferred sampling method of biological material. The suitability of a less invasive approach that involves obtaining samples by swabbing the fish skin (including live, non-ane...

The European Turtle Dove, Streptopelia turtur, a long-distance migrant wintering in Africa, is a widespread Palearctic species. This species is classified as vulnerable and is undergoing a long-term demographic decline. The results of the previous study (based on mitochondrial (mtDNA) cytochrome-b (cytb) sequences of birds fromWestern and Southern...

Simple Summary The European Turtle Dove, Streptopelia turtur, is a widespread Palearctic species. Due to a long-term population decline, it is listed as vulnerable by the IUCN. Population genetics studies are important to the management of threatened species. Previous research based on mitochondrial DNA cytochrome-b of European Turtle Doves sampled...

Background. Recent genetic analyses of fish remains, obtained from archaeological sites, revealed that more than 2000 years ago the Baltic Sea was inhabited by sturgeons closely related to the Atlantic sturgeon, Acipenser oxyrinchus Mitchill, 1815. As some wildlife populations of the Atlantic sturgeon are still present in Canadian rivers, we decide...

Analysis of the genetic structure of the European eel (Anguilla anguilla) using the mtDNA cyt b molecular marker. VI Baltic Genetics Congress.

The development and exploitation of Nuclear Power Plants (NPPs) have great impact on aquatic ecosystems. Seeking to establish a tool for monitoring of a long-term anthropogenic effect on the population genetic structure of fishes it is necessary to create a molecular database of the model fish species. The aim of the study was to assess genetic var...

This is summary of my doctoral thesis.

The population genetic structure of the Woodpigeon (Columba palumbus) in Europe was studied analyzing the distribution of different D-loop haplotypes among bird samples, collected in various breeding and wintering sites of the species (in Russia, Belarus, Lithuania, Sweden, Hungary, France, Spain and Portugal). Totally 89 different haplotypes ascer...

Information about the Anguilla anguilla genetic variability derived from mtDNA D-loop region sequences is limited. Thus our research group updated 80 European eel mtDNA D-loop region sequence database created 10 years ago by adding 37 unique sequences. A total of 45 newly determined sequences represent the European eels recently cought in the Lithu...

Today, there are only two information sources about Anguilla anguilla mtDNA D-loop region haplotypic variety and both are quite old. Our research group updated the ten year-old mtDNA D-loop region database of 80 sequences by adding the homological sequences of 45 European eels caught in Lithuanian territorial waters, i.e., in the Baltic Sea, the Cu...

To find out if native and introduced European eel (Anguilla anguilla) populations differ from one another genetically, we used five microsatellite markers and compared naturally recruited and introduced European eel populations at four different locations. Samples of naturally recruited eels were taken from the Baltic Sea and the Curonian Lagoon, w...
