REACTION OF EARTHWORMS (FAMILY LUMBRICIDAE) TO ABIOTIC FACTORS CHANGE
In the structure of the population of earthworms the following specieswere revealed: Eisenia nordenskioldi (Eisen, 1879), Allolobophora parva (Eisen, 1874), and Lumbricus rubellus (Hoffmeister, 1843). The first species is widespread, it was found in all the investigated habitats. The range of deviat...

| Summary: | In the structure of the population of earthworms the following specieswere revealed: Eisenia nordenskioldi (Eisen, 1879), Allolobophora parva (Eisen, 1874), and Lumbricus rubellus (Hoffmeister, 1843). The first species is widespread, it was found in all the investigated habitats. The range of deviation (R) was 42 to 6 specimen per 1 m2. The coefficient of variation in number of the studied population of lumbricids in all the ecotopes was 33,5 %. The animals were discovered to have a strong reaction to soil pollution with oil products and to sharp change in humidity (R = 0,88 ± 0,13 and R = 0,85 ± 0,13) by means of active vertical migration to more optimal habitats. |
