Summary

The thesis data are revealed in 148 pages including introduction, four chapters, conclusions and practical recommendations, 19 annexes, 25 figures, 7 tables. The bibliography includes 200 bibliographic sources.

The purpose of the study: the study of biological and ethological peculiarities of aquatic and semi-aquatic avifauna of the Lower Prut Basin.

Objectives: - identification and monitoring of aquatic and semi-aquatic bird species; accomplishment the observations of biology and ethology by birds species included in our study; identify nesting territories and the flocks of brooding aquatic and semi-aquatic birds; establishment intra-and interspecific relationships in various types of behavior in aquatic and semi-aquatic avifauna; revealing ecological similarity of habitats and avifauna of the Lower Prut Basin.

Novelty and originality of scientific: Identified 75 species of aquatic and semi-aquatic bird species belonging to 6 orders, placed in 14 families. The most numerous is the order Charadriiformes which consists of 26 species, followed by Anseriformes with 22species, Ciconiiformes with 13 species. Was estimated spatial distribution of aquatic and semi-aquatic birds and seasonal dynamics covering all six phenological seasons, have been elucidated in the fist intra-and interspecific behavioral relationships; was established ecological capacity of ecosystems.

Theoretical significance and applied value of the thesis: The theoretical importance of study is to develop a detailed and integral system of knowledge about ecology and population structure of aquatic and semi-aquatic birds in the Lower Prut. Researches are framed into the scientific research directions, priority programs and national and international strategies of protection and conservation biodiversity, which is a significant contribution towards international Conventions: Ramsar, Rio de Janeiro, Bern, Bonn, etc. which Moldova joined.

Implementation the results. As result of the study of aquatic and semi-aquatic avifauna have been proposed for local public administration to implement the following activities:
- Prohibition of fishing, limitation lake access during the hatching of cubs;
- Establishment of a zone of strict security during the breeding aquatic and semi-aquatic species in the decade from May to July;
- Undertaking hydro technical works for regulating water flow at the inlet and outlet water to create optimal conditions for living and breeding birds and other animals of the Lower Prut (avoid flooding or drainage of large portions of pond).
