Seasonal activity of earthworms (Oligochaeta, Lumbricidae) from the belt of broad-leaved forests in Kabardino-Balkarian state high-mountain reserve and adjacent territories (Central Caucasus)

Species diversity, biotopic distribution and seasonal dynamics of abundance indexes in earthworms from middle mountains biotopes of various hydrothermal regimen are studied. Aporrectodea handlirschi (Rosa, 1897) has been first identified in the Central Caucasus. The change from summer diapause in A. rosea (Savigny, 1826) in first re-corded in the North Caucasus.
