Zoology
Galina BUSMACHIU L’viv districts in Ukraine [17]. It is a forest species that lives in the litter, under the bark of dead tree or in the moss on wood decompose. This species were recorded in several natural forests in the Republic of Moldova [4] and the specimens were collected usually near the decaying wood. A special interest presents two species from the family Neanuridae. First of them — Neanura moldavica [6] has been described from the Republic of Moldova (Piaiul Faguiui nature reserve). The species is recorded from many localities in Moldova, from litter, decaying wood of all kinds of silvicolous habitats (Pinus and Populus forest plantations, riparian, natural Fagus and Quercus forests) being very common in the country. The second species is Thaumanura carolii described by Stach in 1920 as Achorutes carolii from the Beskidy and Pieniny Mountains (South Poland). Later, in 1951 Stach mentioned additional localities of the species distribution from Austria, Bulgaria, Hungary, Poland, Slovakia, Ukraine and the former Yugoslavia. In our days Thaumanura carolii is an European species reported from the Alps, the Carpathians, the Sudetes and the Balkan Mts. [27]. In the Republic of Moldova the specimens of this species were collected from litter, rotting wood, moss and under bark of decaying logs of Codrii and Piaiul Fagului forest reserves and the natural deciduous forest near Donici village, being more abundant during the cold season, often under the snow. a b Photo 2: a — Orchesella pseudobifasciatcv, b — Lepidocytrus paradoxus. Pseudosinella simpatica [13] has been described from Acerum-Carpenetum type of forest from Codrii Reserve, being identified also in Robinia pseudoacacia plantation of two other localities from the Central part of the country. Collembola are well differentiated into ecomophological life-forms groups. According to Rusek [25] the life-forms structure is an important parameter of Collembolan communities and reflects the state of soil development during succession and can bioindicate soil microstructure and humus form. Some life-forms are restricted to a different vertical layer of the ecosystem and therefore their functional role depends on occupying soil subhorizons. Edaphobiont group of Collembola were differentiated by Rusek [23] in euedaphobiont, hemiedaphobiont and epigeont. Euedaphic life-forms dominate in the deeper soil horizons and include the species from the families Tullbergiidae, Onychiuridae, Neelidae, Arrhopalitidae and some small, blind representatives of other families, including the species from genera Willemia, Isotomodes, Cyphoderus that constitute 23.2 % from the species identified in our reserve. Hemiedaphic life-forms belong to the species from genera Pseudosinella, Folsomia, Proisotoma, Parisotoma, Tomocerus, Pogonognathellus etc. that constitute 33.9% of studied species living in litter, upper soil horizon and wood decompose. Epigeont and atmobiont life-forms belong to the families Katiannidae, Dicyrtomidae, Sminthuridae and genera Isotoma, Desoria, Lepidocyrtus and Orchesella are in many cases present in moss, on bark of trees and live plants, feeding on algae, fungus hyphae, 84
