Fig. 1: Scientific Reserve Codrii This study is the part of a long - term investigation (1994-2013 years) carried out in Codrii reserve divided into 3 functional zones: a strictly protected zone, a buffer zone, and an intermediate zone. Samples were collected in the different types of habitats of all functional zones, in the forests soil and litter, rotten trunks of oak covered by moss. The most part of the forest is mixed on the base of oak trees (Quercus petraea and Quercus robur) typical for reserve in combination with lime-ash (Tilia tomentosa — Tilia cordata — Fraxinus excelsior) and maple-hornbeam (Acer campestre — Acer platanoides — Carpinus betulus). The strictly protected zone includes also monodominant beech forest (Fagus sylvaticd). In the buffer zone there are several types of trees plantations such as Robinia pseudoacacia, Betula sp., Pinus nigra, Picea sp., meadows and shores of lakes. Additionally, the specimens of Collembola from alfalfa crop and apple orchard situated into intermediate zone of reserve were collected for the study. The specimens were extracted using modified flotation method [7] and fixed in 96% ethyl alcohol, sorted, cleared in lactic acid and KOH and mounted on permanent slides using Marc-Andre II solution. The specimens were identified using a phase contrast microscope LEICA 2500 equipped with camera Lucida. For identification of Collembola determination keys published within Synopses on Palaearctic Collembola [2, 10, 15, 21, 29] including some additional papers 82
