Summary

The thesis consists of introduction, 4 chapters, general conclusions and recommendations, bibliography of 165 titles, 132 pages of basic text, 69 figures, 4 tables. The results are published in 25 scientific papers.

The aim of the paper: to elucidate the faunal diversity of bat communities in the central and northern part of the Republic of Moldova, highlighting the ecological peculiarities of hibernation and reproduction of bat species and revealing their importance in nature and in human life.

Objectives: For the first time, complex research was carried out on the communities of bats in underground shelters. New sites for hibernation and breeding of bat species have been found. Morphology data have been updated and maps of bat cave species have been developed. The biological and ecological peculiarities of the species, the qualitative and quantitative composition of the hibernation and reproduction colonies from various underground shelters were highlighted. The current status of the populations of troglodyte bats has been established and the limiting factors are highlighted.

Scientific novelty and originality. For the first time, complex research was carried out on the communities of bats in underground shelters. 6 new sites for hibernation and reproduction of certain bat species were identified. Morphology data have been updated and maps of bat troglophyte species have been developed. The biological and ecological peculiarities of 11 species of bats of 5 genera, the qualitative and quantitative composition of the hibernation and reproduction colonies in various underground shelters were highlighted. The current status of the populations of troglodyte bats has been established and the limiting factors are highlighted.

The scientific problem consisted is highlighting the morphological, biological and ecological features, the structure of the chiropteran communities during hibernation and breeding, and elucidating the preferences of the species for a particular shelter. The factors that influence upon the number decrease of bat populations have been elucidated.

Theoretical significance. The morphological, biological and ecological peculiarities of the troglodyte species were elucidated. The seasonal and multiannual dynamics of the bat communities in underground shelters were elucidated. The research conducted is part of the priority scientific directions and research, in national and international programs and strategies, on the protection and conservation of biodiversity, which is a significant contribution to the implementation of international conventions, to which the Republic of Moldova has acceded.

The applicative value of the paper. The importance of bats in nature and the human economy has been emphasized. The results obtained serve as a support for the methodology of bat populations monitoring in underground shelters. Following the research, a series of recommendations were developed on the conservation of bats and their habitats, emphasizing the importance of educating and involving the general public in the protection of chiropterofauna.

Implementation of scientific results. The obtained results were used by specialists as methodological support in the elaboration of a guide. The research results were applied in the process of elaboration and establishment of protected areas within the Emerald Network, as well as in the implementation of a cross-border project with Romania. The information about this group of mammals is used and implemented in the teaching process, in the realization of bachelor's and master's theses at educational institutions with biological and ecological profile. The data will be used in the elaboration and drafting of the 4th edition of the Red Book of the Republic of Moldova.
