Aquatic invertebrates of watercourses of the Republican landscape reserve “Naliboksky” (Belarus)

Abstract

Studies of watercourses of the Republican landscape reserve “Naliboksky” have revealed 134 lower defined taxa (LDTs) belonging to 3 types of invertebrates: Mollusca – 25, Annelida – 8, Arthropoda – 101 LDTs. A total of 106 taxonomic elements were identified to the species, of which 68 were new to the water bodies of the reserve. From 18 to 54 LTDs were collected in each watercourse. The average number of identified LTDs in the watercourse was 31.9 LTDs. The number of aquatic invertebrates in the studied watercourses varied from 18 to 776 specimens, the average value of this indicator was 234.6 specimens. Among the collected aquatic invertebrates, a protected species were identified – Brachytron pratense (Müller, 1764), as well as a poorly studied species in Belarus Gomphus flavipes Charpentier, 1825. Among the identified hydrobionts in the watercourses of the landscape reserve “Naliboksky”, 23 species are included in the Red Lists of a number of European countries.Thus, the fauna of the studied animals in the watercourses of the Republican landscape reserve “Naliboksky” is relatively rich and represented by rare and protected animal species in Belarus and Europe.
