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 research of parasitoid calcidids associated with the cinopid Neuroterus quercusbaccarum L. (Hymenoptera, Cynipidae) was performed in the forest ridges of the northern and central districts of the Republic of Moldova during the years 2016-2018. In total, more than 1000 gallons were collected, of which eights pecies of entomophagus included in 7 genres and 6 families were obtained under laboratory conditions: Pteromalidae – Mesopolobus tibialis Westw., M. Fasciiventris Westw.; Eupelmidae – Eupelmus fulvipes Förster, Eulophidae – Olynx gallarum L., Tetrastichus sp., Ormyridae – Ormyrus diffinis Fonsc., Eurytomidae – Eudecatoma biguttata Swed.; Torymidae – Torymus flavipes Walker. In the parasitoid complex with a higher percentage of parasites, threes pecies were found: Torymus flavipes Walker (Chalcidoidea, Torymidae), Mesopolobus tibialis Westw., M. Fasciiventris Westw. (Chalcidoidea, Pteromalidae). The lowest percentage of parasites was recorded in Tetrastichus sp. (Chalcidoidea, Eulophidae). Torymus flavipes Walker iscited as a new species for Moldova’s fauna. For the first time there has been infestation of this host with parasitoids: Mesopolobus fasciiventris Westw. (Pteromalidae), Ormyrus diffinis Fonsc. (Ormyridae), Eudecatoma biguttataSwed. (Eurytomidae), Eupelmus fulvipes Förster (Eupelmidae); Tetrastichus sp. (Eulophidae), Torymus flavipes Walker (Torymidae).

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 is devoted to the formation and evolution of an independent language policy in the new post-Soviet sovereign states, each of which, despite similar processes, has its own specifics, due to both internal and external factors. The author focuses on the language policy in the Republic of Moldova, as stated in the language legislation, as well as on the extraordinary collisions that have arisen and are arising in dealing with language issues in this multi-ethnic republic during the 30 years of its independence. Since there are no special comprehensive studies on this topic at present, the article is an important attempt to give an analytical overview of language policy in the Republic of Moldova with relevant sociolinguistic comments on the documents forming its legal sphere, as well as taking into account the specifics of such regions as the unrecognized Transnistrian Moldovan Republic and the Autonomous Territorial Unit of Gagauz-Yeri. The article introduces the latest documents and materials on language policy of Moldova for the first time. The logic of the article structure enables to present the three key directions of language policy in the republic in a consistent and sufficiently detailed manner: language policy regarding the state language, with regard to the Romanian influence on it; policy regarding the Russian language as a popular means of inter- ethnic communication with a sufficient index of sustainability and its status; and policy regarding the languages of ethnic minorities that have long lived in the Moldovan region. The article gives a holistic view not only of the documents, but also of the motives, circumstances and processes of their adoption, as well as the consequences of each new step in the language policy promotion in the Republic of Moldova.

In the present article the author presents a review of piano preludes written by Moldovan composers in the second half of 20th century which are frequently studied at the Academy of Music, Theatre and Fine Arts of the Republic of Moldova. The author seeks to characterize their imagery, musical language means and technical difficulties that can be encountered by young performers. The works analyzed are approved in the author's teaching practice. The preludes were written by Gheorghe Neaga, Vladimir Rotaru, Semion Lungul, Constantin Rusnac, Alexei and Marian Stârcea, Vitaly Sechkin. Some information about these miniatures can be found in research by musicologists E. Kletinich, A. Miroshnikova, E. Gupalova. A detailed analysis from a performer's standpoint presented in the article is made for the first time. The piano pieces indicated above are diverse. The two preludes by A. Stârcea contrast with one another: one has a lyrical character, whereas the other one differs in its drama and flustered character. The piece by Gh. Neaga bears the traces of impressionist music. C. Rusnac’s and V. Rotaru’s creations are composed using Moldovan doina stylistics, and S. Lungul’s lyrical miniature is nationally neutral. In the two preludes by M. Stârcea, modern musical language means are used, and sharp rhythms and dissonant harmonies abound. The article also presents five preludes-pictures by Vitaly Sechkin, a Ukrainian composer who spent his last period of life in Moldova. Inspired by Moldovan vivid landscapes, they differ in their imagery and tempo. Nonetheless, each of the miniatures has its own individual appearance and peculiarities of style. All the works reviewed are distinguished by bright themes and original music language. They represent a substantial enrichment of national piano repertoire and are a striking contribution of autochthonous authors to the development of the prelude genre in the world’s piano music.
