Winkler D. - Traser Gy. N.: Eco-faunistic study on the Collembola fauna in the Vasvár-Nagymákfa area (Őrség, Western Hungary)
Winkler, D. & Traser, Gy. N.: Study on the Collembola fauna 41 species have been stored in the archives of the authors. Springtails were identified at the species level according to Gisin (1960), Stach (1960, 1963), Massoud (1967), Deharveng (1982), Fjellberg (1980, 1998), Babenko et al. (1994), Zimdars & Dünger (1994), Weiner (1996), Jordana et al. (1997), Pomorski (1998), Bretfeld (1999), Potapow (2001) and Thibaud et al. (2004). Taxonomic classification is primarily based on the annotated checklist of the Hungarian Collembola fauna (Dányi & Traser 2008). Abbrevations used in the descriptions: Ant. = Antennal segments; Abd. I-VI = abdominal tergites. Data analysis Average abundance values (specimens/100 cm3) for each species per habitat type are given. Data obtained using the suction sampling method were not included in the quantitative analysis, only grades of abundance (Berndt & Winkel 1983) were given for the additional species. The attributes of Collembola communities in the sampled habitats are presented via comparison of species richness, ecological composition, abundance and diversity indices. On species level, we used the measure 'habitat amplitude' (HA), according to the formula of Simpson (1949), which reflects the relative abundance of each Collembola species in the sampled habitats. Rank abundance curves were used to examine general trends in the Collembola dominance structure and abundance for each habitat type. Dominance structure was quantified by using community dominance index (CDI), which reflects how large a proportion of the total species present (in terms of numbers of individuals) is made up of the two most abundant species. Two measures of species a diversity were calculated for each habitat: the Shannon index (H’ = p; In p;) and equitability (J = H’ / ln S - where S is species richness). Community structure comparison between the different habitats was estimated using single linkage cluster analysis based on the Jaccard and Bray-Curtis similarity indices. Results and Discussion Faunistical results A total of 5557 specimens representing 14 families and belonging to 67 species (Table 1) were collected and identified. Up to the present time 54 Collembola species have been reported from the Őrség area (Traser 1995). Out of the species collected in Vasvár- Nagymákfa, 49 are new to the fauna of Őrség peaked at 103 species recently. Two species, namely Tetracanthella pericarpatica Kaprus & Tsalan, 2009 (Isotomidae) and Arrhopalites acanthophthalmus Gisin, 1958 (Arrhopalitidae) proved to be new to the Hungarian fauna, therefore some detailed information and illustrations are given below. Furthermore, a rare and interesting species, Pseudosinella cf. horaki Rusek, 1985 (Entomobryidae) is also illustrated and described. Tetracanthella pericarpatica Kaprus & Tsalan, 2009 (Fig. 2) was formerly known only from the Transcarpathian Lowland and Roztochchia Hill, Ukraine (Kaprus & Tsalan 2009). A total of 65 specimens were collected mainly from the lowland riverine oak-ash-elm forest, but it also occurred, in lower abundance, in the tall herb fen meadow association.
