Opis:
The origin of the Piast dynasty is a matter of lively discussions and disputes. At least a few controversial hypotheses exist, but their credibility is difficult to assess due to the scarcity of written as well as material sources, especially from the time of Polish state formation. Life sciences, however, can support history and archeology. Application of genetic tests, used earlier mainly in forensic laboratories, enabled identification of the remains of King Richard III, the Romanov dynasty members and Nicolaus Copernicus. Contemporary DNA studies, based on next generation DNA sequencing, outreach the narrow area of known markers such as mitochondrial DNA (mtDNA) and selected regions of Y chromosome. Although ancient DNA (aDNA), extracted from remains, is usually highly degraded and contaminated with genetic material of microorganisms, there are methods which allow for the analysis of such material and retrieval of information about origin, kinship and some phenotypic features of an individual. Genetic studies of the Piast dynasty, a subject of our research project, have to deal with numerous difficulties. In or der to gain access to bone samples, we need to meet a number of formal requirements. Moreover, despite the existence of available abundant documentation on the Piast burials, the actual situation is not always consistent with the written sources. Our first experiences show how difficult it is to localize the remains, identify them and extract DNA of sufficient quality.

Opis:
The family Gobiidae is the largest teleost family, consisting of more than 2,000 species in more than 200 genera. They have adapted to a wide range of habitats, inhabiting mostly marine and brackish waters. Recently invasive Ponto-Caspian gobies have caused significant changes to the structure of fish assemblage throughout the European waters. The aim of the study was to verify the possibility of identifying three species of the genus Gobiidae based on the analysis of the mitochondrial region of the cytochrome oxidase subunit 1 (COI) gene. 339 samples originated from seven countries and 17 different sites were investigated. Qualitative and quantitative assessment of the extracted DNA was conducted by measuring light absorbance and electrophoretic separation. Approximately 650-bp (base pairs) fragments were amplified from the 5' region of the mitochondrial COI with the PCR (polymerase chain reaction) reaction. Sequences of 652 bp were obtained and compared with reference sequences in the National Center for Biotechnology Information (NCBI). Based on the sequence analysis, we determined that in the analysed geographical regions, the goby preliminary identified morphologically as the round goby was represented by three species: round goby (Neogobius melanostomus), tubenose goby (Proterorhinus marmoratus), and monkey goby (Neogobius fluviatilis). The latter two are newly reported for their new habitats. Genetic characterisation of such populations offers the opportunity to assess their genetic stability, which provides agencies managing the aquatic environment in EU countries with a tool for revising the legislation, including regulations relevant for updating the status of native and invasive species in European waters.

Opis:
Genetic markers in mitochondrial and chloroplast DNA were analysed to determine the native status and possibly trace the origin of the silver fir (Abies alba Mill.) growing outside this species natural range in Osusznica Forest District (northern Poland). The provenance of the extralimital populations were determined through comparison with reference samples from the native range of silver fir in Poland and Ukraine. Our results suggest that the Sudety Mts. are the most probable region of the origin of fir from Osusznica. It also seems that the plus seed stands in Osusznica can be treated as a valuable archive of the genetic resources of the fir from the Sudety and, if necessary, may support program of this species restitution.

Opis:
The origin of the Norway spruce in the Gołdap Forest District from the north−eastern part of Poland was verified using the maternally inherited mitochondrial marker mt15−D02, which in Poland displays a geo−graphical specifity. We analyzed 730 trees from 29 populations and 21 plus trees. These populations included four reserves, four registered seed stand and 21 managed tree−stands. As a result of the performed analyses it was found that 8 out of 21 plus trees were non−native. Also 11 out of the 29 investigated pop−ulations contained trees of non−native origin. The scale of this phenomenon varies, although it encom−passes the entire region of the forest district.
