Survey of Collembola (Hexapoda) of the Codrii Reserve [1, 11, 12, 20]. Morphological differences among Collembola living in different habitats was classify into life forms according to Rusek [25] and the aspects of ecological adaptations to various conditions of terrestrial ecosystems were selected from the papers [8, 11, 12, 18, 21]. The slides collection is stored in the Entomological Museum of the Institute of Zoology of Academy of Sciences of Moldova. Photos of collembolan species included in the paper were taken with Canon EOS 60D camera at the „Muséum National d’Histoire Naturelle” Paris, France. Results and discussions As result of investigation 112 species of Collembola belonging to 57 genera and 15 families were found in the studied habitats of Codrii Reserve. The highest number of registered collembolan was from the family Entomobryidae (29 species and 7 genera), followed by the families Isotomidae (19 species and 11 genera), Neanuridae (11 species and 7 genera), Hypogastruridae (10 species and 5 genera), Onychiuridae (9 species and 5 genera), Tullbergiidae (7 species and 3 genera), Tomoceridae (5 species and 3 genera) and Katiannidae (5 species and 2 genera). Two families Sminthuridae and Dicyrtomidae were represented by 4 species (4 and 3 genera respectively), when the families Neelidae, Arrhopalitidae by 2 species and 2 genera, Odontellidae and Cyphoderidae by 2 species from one genus each. The family Sminthurididae was represented by one species and genus only. The list of collembolan species including localities, distributions, life forms and some aspects regarding habitat preference and ecology of revealed in the Codrii reserve species have been included in the table 1. The plant communities are the most important soil forming factors [19], as well as the influence of soil microflora and pedobionte animals on soil structure. The attention was drawn to the collembolan communities’ structure and species diversity of different habitat taken separately. As a result of investigation the collembolan species typical for the forest including litter, soil, moss, mushroom, wood decompose and open habitats as meadow and alfalfa were revealed. In the litter of the natural forests the following species were found: Ceratopysella engadinensis, C. succinea, Schoettella ununguiculata, Xenylla boerneri, X. brevicauda, X. brevisimilis brevisimilis, Friesea mirabilis, Pseudachorutella assigilata, Pseudachorutes subcrassus, Deutonura albella, Neanura moldavica, Entomobrya muscorum, E. quinquelineata, Pseudosinella albida, P. boraki, P. moldavica, Heteromurus major, Lepidocyrtus lignorum, L. paradoxus (photo 2b), L. violaceus, Folsomia quadrioculata and E penicula. The typical species collected under and into the wood decompose covered by moss are: Superodontella montemaceli, S. lamellifera, Orthonychiurus rectopapillatus, O. stachianus, Onychiuroides granulosus, Desoria olivacea, Pogonognathellus flavescens, P longicornis, Tomocerus minor, T. vulgaris, Dicyrtomina minuta and Neelus murinus. Only in moss was found Orchesella pseudobifasciata (photo 2a). Some soil species such as Mesaphorura yosii, M. florae, Metaphorura affinis, Isotomodes productus and Folsom ides parvulus have been found in open habitats — meadows or alfalfa crop near the forest, while the species Ptenothrix atra, Caprainea marginata, Lipotbrix lubbocki, Gisiniaus flammeolus and Spatulosmintburus flaviceps are considered macrophytobiont, being collected from the moss, mushrooms and open habitats. Among the identified collembolan species found in Codrii reserve some deserve particular attention. The species Superodontella montemaceli has been described from Poland (Pieniny Mt.) [1] and then found in the litter and soil of leafy forest from Ivano-Frankivs’k, Zakarpattia and 83
