Once widespread in the large European rivers, Palingenia longicauda underwent a drastic range contraction as a result of the intense pollution and hydromorphological interventions of the 19th and 20th centuries. For the last decades it was considered to be restricted only to the Tisa River and its tributaries, and to the Rba&aacute River, but new reports indicated its presence in the Danube River in Hungary, in the Danube Delta in Romania and Ukraine, and in the Prut River in the Republic of Moldova. The objective of this study is to analyze the phylogeographic pattern between the two main eco-regions (Pannon and Pontic) of the species distribution, based on the combined mitochondrial COI (472 bp) and 16S (464 bp) sequences generated for individuals collected in Romania and Ukraine, and from publicly available ones, representing the Tisa catchment populations. The presence of viable populations in the Danube Delta and on the Prut River in Romania is confirmed, and additional presence on the Mureș and Bega rivers from Romania, and on the Styr and Horyn rivers in Northern Ukraine is shown. The phylogeographic results indicate that the presence of the analyzed populations are not the result of recent founding events from the Pannon region, confirming the survival and expansion of cryptic local lineages. The recent recovery of the species may be related to the improvement of water quality as a result of the implementation of the EU Water Framework Directive and the EU Floods Directive after 2000.

This article presents important steps and achievements accomplished by the Republic of Moldova towards integration, by analysing its collaboration with the European Union.  The development of relations with the EU is the priority goal that Moldova strives for, which means not only economic, but also political and cultural integration.  The first steps of the Republic of Moldova towards the EU were encouraging.  After years of isolation, this process was difficult and required a lot of efforts.  This is due to many reasons, the most important of which are Russia's political and economic pressure, theunresolved issue in Transnistria, the ideological and geopolitical schisms of the population, some of which see their future with Russia, and the other part with Europe.  Despite the existing problems, cooperation with the EU has yielded tangible results: the EU-Moldova Association Agreement has been signed, the visa regime has been abolished and financial support for the socioeconomic and public sectors is provided.  Moldova, for its part, is making great efforts to form a single political, economic and cultural educational space with the EU, which supports its efforts in the process of European integration.  Its speed and success largely depend on the country itself, its economic and political development.  A strong statepolicymaking aimed at strengthening reforms and stimulating the transition to a market economy in accordance with the international principles is inherent in the future development of Moldova. Keywords: Republic of Moldova, European Union,European Integration, foreign policy, Transniestrian conflict

The article examines the issues of counteracting the hybrid aggression of the Russian Federation in the countries of the Eastern Partnership. It is stated that European Union has been implementing the Eastern Partnership policy for more than ten years. This implementation has been a resounding success for all, without exception, the six target states. Ukraine, the Republic of Moldova and Georgia have advanced much more in their European aspirations. However, this does not stop the Russian Federation from further positioning all the states that were once part of the USSR as a sphere of its ultimate influence. Russia is also producing rivalry with the EU for influencing all, without exception, the Eastern Partnership states and even the EU. An overview of academic research analyzing the resilience of the EU in the face of Russia in the context of its impact on the Eastern Partnership countries is set out in this article. Some approaches have been used to define the EU as a “normative power” and Russia’s controversial policy towards neighbouring countries. The examination of the works described in the article concludes that the Russian Federation continues to regard neighbouring states as its sphere of influence, particularly Ukraine, Moldova, and Georgia. Moscow considers any attempt by a third party to interfere as an intrusion on its unique field of power. As can be observed from the investigated sources, Russia’s activities are scarcely diplomatic or focused on global democratic norms. In its Eastern Partnership strategy, the EU, on the other hand, utilizes values as a guideline. Simultaneously, Ukraine, the Republic of Moldova, and Georgia must demand immediate modifications to the Eastern Partnership policy. The potential of EU membership, in particular, must be appropriately explained by Brussels.

The present work presents the results of the research of the ichthyofauna of the largest accumulation lakes in the Republic of Moldova (Dubăsari on the Dniester River and CosteștiStânca on the Prut River) under the conditions of climate changes and intensification of anthropogenic pressure. The state of profound change in the ichthyocenosis of the Dubasari reservoir is demonstrated, which is currently dominated by small species (gobius species, bleak, bitterling, blackstriped pipefish), and indicates the urgent need to carry out ameliorating measures of populating the ecosystems with economically valuable species of fish, among which a significant share shall be placed on ichthyophagous species of fish, such as pikeperch, northern pike, catfish, asp. The higher share of oxyphilic and reophilous fish species in the fish catches from the Costești-Stânca accumulation lake reveals a more favourable ecological status of this ecosystem compared to the Dubasari accumulation.

The fundamental thesis of this paper is that the European Union has, at its disposal, economic and political tools to resolve conflict in Transnistria. The EU Association Agreement signed with the Republic of Moldova is an important instrument which could be used to reintegrate Transnistria with Moldova. In the long term, the flourishing Moldavian economy associated with the EU might prove a more attractive alternative for Tiraspol than dependence on unpredictable Russia. However, Russia continues to play an important part in the efforts to solve the conflict.

The article discusses the historical geography of the river Prut (967 km). In the ancient period it was known as the Pyretus, Porata, or Prout. The river originates on the eastern slope of Mount Hoverla (2 068 m), in the Carpathian Mountains in Ukraine. The Prut flows to the southeast, eventually joining the Danube near Giurgiuleşti, east of Galați. The Prut currently divides three countries: Romania, the Republic of Moldova and Ukraine. At present, it constitutes the border between Romania and Moldova, with a total length of 695 km. It has a hydrographic basin totaling 27 540 km2 , of which 10 990 km2 are in Romania and 7 980 km2 in Moldova. The article presents a summary description of the geographical setting and hydrographic specificity of the Prut River. The main geo-morphological characteristic features of the Prut basin are presented. The author also offers a historical overview of the main settlements situated on the river, as well as a brief analysis of the recent projects for international cooperation centered on the Prut as an important waterway of the region. Finally, the author emphasizes the role of the Prut as a border river, looking at both the pragmatic and symbolic dimensions of its significance for Romanian history.

The article analyzes the visa-free regime of the Republic of Moldova within the framework of the CIS and the European Union. The main steps towards achieving the visa-free regime are reviewed. The authors investigate the process of implementing the visa-free regime with the European Union as a recent success of the Republic of Moldova. At the same time, the authors identify the positive and negative effects that accompany the introduction of the Republic of Moldova — European Union visa-free regime. A comparative analysis with other post-Soviet countries that have also obtained the visa-free regime (Georgia and Ukraine) is conducted. The authors note that a visa- free regime is an important tool that allows the EU to regulate relations with third countries. This regime provides important benefits for citizens and strengthens social, cultural, and economic ties between the EU and its partners. At the same time, the visa-free regime holds it responsible for maintaining the progress achieved in the framework of the visa liberalization dialogues and for ensuring a well-managed migration and security environment. The article makes wide use of statistical and sociological data as well as analytical and empirical materials.

The article presents the results on qualitative and quantitative indicators of phytoplankton of the Prut River lower sector within the Republic of Moldova in 2018-2020. In phytoplankton compositions 72 species were identified. Seasonal and long-term patterns of phytoplankton development have been established in Prut River lower sector. The numbers of phytoplankton changed within the limits 1,06 to 20,32 mln. cell/l, with biomass 1,23-21,64 g/m3. The values of saprobic indexes, estimated on the basis of species-indicators (52 species) from phytoplankton composition, which are in proportion of 58% typically β-mezosaprobic, confirm the following: the water quality of lower Prut River sector in the period 2018-2020 was satisfactory for the development of phytoplankton and was attributed mainly to II-III (good-moderately polluted) quality classes.

Abstract. The year 2010 was characterized by devastating flooding in Central and Eastern Europe, including Romania, the Czech Republic, Slovakia, and Bosnia-Herzegovina. This study focuses on floods that occurred during the summer of 2010 in the Prut River basin, which has a high percentage of hydrotechnical infrastructure. Strong floods occurred in eastern Romania on the Prut River, which borders the Republic of Moldova and Ukraine, and the Siret River. Atmospheric instability from 21 June–1 July 2010 caused significant amounts of rain, with rates of 51.2 mm/50 min and 42.0 mm/30 min. In the middle Prut basin, there are numerous ponds that help mitigate floods as well as provide water for animals, irrigation, and so forth. The peak discharge of the Prut River during the summer of 2010 was 2,310 m3/s at the Radauti Prut gauging station. High discharges were also recorded on downstream tributaries, including the Baseu, Jijia, Miletin etc. High discharges downstream occurred because of water from the middle basin and the backwater from the Danube (a historic discharge of 16,300 m3/s). The floods that occurred in the Prut basin in the summer of 2010 could not be controlled completely because the discharges far exceeded foreseen values.
