Abstract

Springs (krinitsy, istochniky, keys) along with lakes, the rivers and swamps provide biological diversity of water ecosystems and richness of a plant and animal life. The spring is not the biggest ecological system among other types of the surface water. Division of springs on limnokrene (over an exit of one or several sources the small reservoir with an open water mirror with the following stream), reokrene (a visible source with the following stream) and gelokrene (a set of diffusively located exits with education cryopole marsh type with the following stream is formed) is standard. Sources are important in a delivery of reservoirs and water currents, maintaining of water balance and maintaining stability of the biocenoses surrounding them. Springs are inhabited by fauna which part natives of cold reservoirs of the North of Eurasia and mountainous areas of Central and Southern Europe and also evribiontny organisms are. The taxonomic structure of aquatic invertebrates of 9 springs in the Brest district has been established. 57 species of representatives of 4 types of aquatic invertebrates were identified: Mollusca – 12; Platyhelminthes – 1; Annelida – 3 and Arthropoda – 41 species and forms. Relatively high species abundance of larvae from the order Plecoptera, Ephemeroptera and Trichoptera was noted. The richest fauna of aquatic invertebrates was represented in the source in the vicinity of the village Selets (Berezovsky region), and the largest number in a spring in the vicinity of the village Verkhi (Kamenetsky region). Among the identified aquatic invertebrates, the following species should be noted: Synurella ambulans (F. Müller, 1846) and a rare for Belarus beetles Agabus guttatus (Paykull, 1798).
