1 9 4 P. Skubała O ribatid m ites are usually the m ost a b u n d a n t of m ites occurring in stable soils. Many a u th o rs are of the opinion th a t oribatids do not take p art in prim ary colonization of newly formed h ab itat ( B r o c k m a n n et al. 1980, H e r - m o s i l l a 1976, H u h t a et al. 1979, K o e h l e r 1983, S t r e i t et al. 1985). Although, oribatids attain an im portant position in aged m aterial, e.g. the sludge m aterial ( H u h t a et al. 1979). In the latter research their biom ass becam e even higher th an in the controls, and of the sam e m agnitude as the average biom asses of Oribatida in spruce forests, which are the optim um of this group. Moreover, D u n g e r (1968) observed su b stan tial populations of oribatid m ites 3 years after the revegetation of m ine spoil. S tudies on the colonization and succession of soil fauna in h ab itats degraded by hum an activities were developed in recent years. However, there are few papers w hich analyse oribatid com m unities on postindustrial dum ps in details ( B e c k m a n n 1988, B i e l s k a 1982a, b, B i e l s k a 1995, L u x t o n 1982, S k u b a ł a 1995, 1996, 1997a, W e ig m a n n 1982, Ż b ik o w s k a - Z d u n 1988). This study focused on the later stage of the succession of Oribatida. Different postindustrial dum ps representing sim ilar stage of the secondary plant succession were chosen. The vegetation was well developed and deciduous trees or sh ru b s occurred at all investigated sites. The paper investigates w hether the oribatid com m unities described on various types of dum ps differ with regard to stru ctu ral biocenotic param eters. The author gives also an account of some more num erous species, as well as ecological and zoogeographical analysis of oribatid com m unities on dum ps are made. A bundance and species richness of mite com m unities were previously discussed ( S k u b a ł a 1997b). SITE DESCRIPTION AND METHODS Following five p o stin d u stria l d u m p s have been chosen in th e U pper Silesia n Region for the analysis: 1. a dum p of a coal-burning power plant in Jaw orzno 2. a dum p of a chem ical plant in Oświęcim 3. a zinc m etallurgic dum p in Katowice 4. an iron m etallurgic dum p in By tom 5. a galena-calam ine mine dum p at Bukowno They were com prised of different in d u strial m aterials originated from different industrial processes. The age of all dum ps were sim ilar (about 30-40 years) and the tall herbage com m unities containing some trees or sh ru b s (Oświęcim) were developed on th ese sites. Detailed inform ation concerning th e site description and m ethods can be found in the first part of a n article (SKUBAŁA 1997b). The species com position w as analysed u sin g the M arczew ski and S te in h a u s form ula (s) ( M a r c z e w s k i, S t e i n h a u s 1959) and classificatory m ethod by M o u n t f o r d (1962). s = w / a b - w w here a - num ber of species in I com m unity, b - num ber of species in II com m unity, w - num ber of species com m on to I and II com m unities.

Oribatida on postindustrial dumps 1 9 5 Diversity of soil anim als (H ) w as calculated using Shannon-W iener index: H' = - I p. lnpu where p( - the proportion of the total species represented by species i. Furtherm ore, the species abundance relationship after L u d w ig & R e y n o l d s (1988) w as also used to com pare the stru ctu re of the oribatid com m unities on dum ps. Oribatid m ites were categorized into three trophic groups (Lu x t o n 1 9 7 2 ): m acro-, micro- and panphytophages. Species were also classified into groups w hich characterized their typical biotope in which m ites usually occurred: forest, open habitats, m osses and lichens on hard su b stra ta and eurytopic species. Furtherm ore, species were classified according to their geographical d istrib u tio n: eu ro p ean, palaearctic, holarctic an d cosm opolitan species. RESULTS The dom inance structure of a com m unity The dom inance stru ctu re of the analysed com m unities differed m uch. A different num ber of species and different species belonged to particular classes of dom inance. The specim ens of oribatids were m ost evenly shared betw een species on the galena-calam ine dum p at Bukowno, where 7 species reached the dom inance index higher th an 5.0%. On the dum ps in Oświęcim and Bytom 6 and 5 species belonged to dom inants b u t a relatively higher proportion of m ost num erous species w as observed. Tectocepheus velatus reached high dom inance on these dum ps (34.0% - Oświęcim and 23.6% - Bytom). The lowest num ber of dom inants and very high dom inance of one species were observed on the rem aining dum ps. Oppiella nova reached 46.7% of the entire com m unity on the dum p in Jaw orzno and 50.9% on the dum p in Katowice (Fig. 1). The stru c tu re of the mite com m unities w as also exam ined using the species-abundance relationship. Individual ra n k /a b u n d a n c e plots for the total num ber of m ites collected on the study sites are presented in Fig. 2. The species abundance relationship w as m uch more steep on the dum p in Katowice and rath e r of m ilder progress on the other dum ps. All these curves differed from the species-abundance relationship observed in the n atu ral beech forest in Polish m ountains (S k u b a ł a, in press). Curves of com m unities from n atu ral biotopes display a log-norm al d istrib u tio n (STENSETH 1979). S p ecies sim ilarity and diversity It is w orth m entioning th a t only 4 species (Liochthonius lapponicus, Quadroppia quaddcadnata madtalis, Oppiella nova and Tectocepheus velatus) occurred on all investigated sites (see Apendix) and as regards dom inants, there were only 2 ubiquitous parthenogens (O. nova and T. velatus). B ut the proportion of these species in com m unities varying m uch. For example, O. nova reached over 50% of the total num bers in Katowice and only 0.25% in Bytom. 8 species were recorded on a t least four dum ps (B rachychochthonius im

Oribatida on postindustrial dumps 1 9 7 C lassification of analysed com m unities with regard to species sim ilarity is illustrated in Figure 3. Sim ilar analysis h a s been m ade also for p lant species. As regards oribatid com m unities the value of the Marczewski and S teinhaus form ula w as highest for Jaw orzno and Oświęcim (s = 0.28). The species com position of th e com m unity in Bytom w as sim ilar to the latte rs. The d e n d ro gram displays a m ain separation betw een the dum p at Bukowno and all other dum ps. For example, there were only 10 com m on species for com m unities in Jaw orzno and Bukowno (s = 0.12). The separate character of the oribatid com m unity on the galena-calam ine dum p a t Bukowno w as also expressed by the highest n um ber of speciess confined to one site (18). Due to the sim ilarity of plant assem blages on dum ps, the relationship were different. In plants, the dum ps in Oświęcim and Bytom were m ost sim ilar. And the dum p in Katowice w as separated from other four dum ps (Fig. 3).

As regards species diversity of the oribatid com m unities, the m ost widely u sed S h an n o n index (H ) w as calculated. Its value increases as the num ber of species increases and as the distribution of individuals am ong the species becom es even. The oribatid com m unity on the dum p in Bukowno w as the m o st diverse (H' = 2.9109) and a little lower w as the diversity in Bytom (H' = 2.7889).

E cological and zoogeographical analysis As far as trophic preferences of oribatid m ites are concerned, the m ajor group w as m icrophytophages. The num ber of these species w as the highest o n all dum ps (ranged from 14 species at Bukowno to 24 species in Jaworzno). A lthough, they reached the highest percentage in total num bers only in the coim m unities in Jaw orzno (61.2%) and Katowice (67.3%). The highest propor

1 9 8 P. Skubała tion of panphytophages w as recorded on the rem aining dum ps. It w as because of very high dom inance of panphytophagous species - Tectocepheus velatus on the dum ps in Oświęcim and Bytom and high proportion of other panphytophages - Oribatula tibialis, Eupelops tardus, Achipteria nitens and Pergalumna nervosa at Bukowno. The proportion of m acrophytophages was generally low, however they reached 10.5% of the total oribatid population at Bukow no. O ribatid species w hich show ed no preferences in h a b ita ts (eurytopic sp e cies) formed generally the m ajor part of all com m unities. The species reached alm ost 40% of the total num bers on the dum p in Bytom and about 75% on the dum ps in Jaw orzno and Katowice. The proportion of forest species was not high (ranged from 7.7% in Jaw orzno to 19.4% in By tom). However, very high num ber of forest species (15, 14 and 12) w as recorded on som e dum ps (Jaw orzno, Oświęcim an d Bytom). Surprisingly, a high n u m b e r of forest sp e cies w as recorded on the dum p in Oświęcim, where trees were absent. Only few m eadow species (characteristic of open areas) was recorded on the dum ps. They com prised the high percentage only on the dum p in By tom (32.4%). In term s of geographical distribution of the recorded species, the m ajor group w as cosm opolitan species on all investigated sites. They com prised from 43.8% of the whole num ber in Bytom to 76.1% in Jaw orzno. The num ber of cosm opolitan species w as not the highest (the num ber of holarctic and palaearctic species w as in m any cases higher th an cosm opolitan ones), b u t some of them reached very high abundance (e.g. Achipteria nitens, Oppiella nova, Oribatula tibialis, Pergalumna nervosa, Tectocepheus velatus and Scheloribates laevigatus). The proportion of holarctic and palaearctic species ranged from 6.8% (holarctic species at Bukowno) to 34.9% (palaearctic species in Oświęcim). Several european species were recorded on each dum p. These species reached the highest proportion on the dum p in Bytom (15.1%). DISCUSSION The observations conducted on several postindustrial dum ps of sim ilar age and developm ent of vegetation allowed to describe five differently developed oribatid com m unities. They differed with regard to abundance, num ber of species ( S k u b a ł a 1997b), the stru ctu re of a com m unity (the differences in species stru c tu re were the m ost rem arkable) and species diversity. The analysis of the dom inance stru ctu re of the com m unities revealed its different ch aracter in the investigated com m unities. The more balanced dom i nance stru c tu re w as observed on the dum p a t Bukowno and Bytom. The stru c tu re of the rem aining com m unities w as m uch less stable. One species (Oppiella nova or Tectocepheus velatus) reached very high proportion in the com m unities in Jaw orzno, Oświęcim and Katowice). The species abundance relationship on the investigated dum ps differed in com parison with the curve of the oribatid com m unity in the n atu ral beech forest ( S k u b a ł a, in press) w hich show ed a tendency tow ards a log-norm al

Oribatida on postindustrial dum ps 1 9 9 distribution (Fig. 2). It h as been suggested th a t log-norm al distributions are considered to be characteristic of greater environm ental stability (STENSETH 1979). On the investigated d u m p s th e curves were ra th e r of logarithm ic d istribution, w hereas on the zinc dum p in Katowice log abundance declined m ost sharply in relation to species rank. A steep decline of the curves may indicates its early successional sta tu s ( K o e h l e r & B o r n 1989). As regards the values of the S hannon index, its value also differed betw een dum ps (from H = 1,8822 in Katowice to 2,9109 in Bukowno). In general the values of the species diversity index were not low. Values of this index varies from 2 to 3.5 in m any n atu ral forest biotopes ( D z iu b a & S k u b a ł a 1986, N i e d b a ł a et al. 1981, R a j s k i 1961, S t a n t o n 1979). As regards other investigated dum ps, B i e l s k a (1982b) recorded the S hannon index, H' = 1.8476 on the 30 years old m ine dum p and H' = 2.2643 on the 20 years old recultivated dum p. W hereas Ż b i k o w s k a - Z d u n (1988) observed the value of the species diversity index, H' = 2.6452 on the recultivated m ine dum p. Aboved characteristics indicated th a t the stru c tu re of the oribatid com m unities are different and mite com m unities on dum ps in Jaw orzno, Oświęcim and Katowice are not well developed and are in the earlier phase of succession th an on two other dum ps. And especially the dum p in Bukowno is of greater stability due to species abundance relationships and the value of diversity index. A strik in g differences in the species s tru c tu re were observed (Fig. 1). Different oribatid species play an im portant role in each of the investigated com m unities. The species sim ilarity was the highest for the com m unities in Jaw orzno and Oświęcim (s = 0.28) and very low for com m unities at Bukowno an d others (Fig. 3). In co n trast to oribatids, the plant com position of the dum p in Katowice was the m ost dissim ilar. The differences in the sim ilarity of oribatid and plant com m unities indicate th at there are m any other factors w hich influence the form ation of the oribatid fauna. One of the reasons could be the presence of particular oribatid fauna around the dum ps. It is worth m entioning th a t the species sim ilarity betw een oribatid com m unities was m uch higher th an betw een plant assem blages. Species of the family Oppiidae dom inated in com m unities on dum ps in Jaw orzno, Katowice and Oświęcim (Bem iniella rafalskii, Dissorhina ornata, Medioppia obsoleta, Oppiella nova and Ram usella assimilis). Their proportion in the rem aining com m unities was m uch lower. They are sm all body sized species, of weak sclerotization, inhabiting sm all pores in the soil, m ainly eurybiotic m ites. Tectocepheus velatus an d species of sim ilar m orphological a d ap tatio n s to the life in the soil (Ceratozetes peritus, Liebstadia similis and Scheloribates laevigatus) prevailed on the dum ps in Oświęcim and By tom. T h ese are species of average size a n d sclerotization, lacking special m orphological adaptation to the life in the soil or on the surface. Species of various type dom inated on the galena-calam ine dum p. Oribatula tibialis and Oribella paolii are m ites of sim ilar specialization as T. velatus w hereas Eupelops tardus, Achipteria nitens, Tegoribates sp., Pergalumna nervosa are strongly sclerotized m ites with m any protective adaptations, well adapted to the life on the s u r

200 P. Skubała face. Furtherm ore, species of sim ilar characteristic to the latter - Oribalella berlesei played an im portant role in the com m unity in Oświęcim. Some of the dom inant species recorded on the dum ps were previously found at postindustrial or disturbed sites at high num bers and are known as resistant to h u m an im pact. They are following species: Dissorhina om ata, Liebstadia similis, M edioppia obsoleta, O. nova, Quadroppia ąuadricańnata, R am usella assimilis, T. velatus (B e c k m a n n 1988, B i e l s k a 1982a, b, 1995, C e r n o v a 1970, L u x to n 1982, S k u b a ł a 1995, 1997a, W e ig m a n n 1982). Furtherm ore, some other species were described as less sensitive to hum an perturbances, namely Scheloribates laevigatus, Eupelops sp. ( D in d a l 1977, S e n ic z a k et al. 1991). The re m aining dom inant species from the analysed postindustrial dum ps were absent or occurred in low num bers in sim ilar researches. As regards some ecological qualities of the recorded oribatids, species known to possess a broad ecological am plitude occurring in a wide variety of habitats throughout the world comprised the major part in all com m unities. It m ay be supposed th a t the proportion of cosm opolitan and euiytopic species will be decreasing in the following years as the vegetation will become more dense and the am ount of organic m atter will increase. The num ber of forest species was quite high on some dum ps. Surely, the proportion of these m ites will be also increasing in next years. A calculation of the relative proportion of trophic types in oribatid com m unities led to the following results: the num ber of m icrophytophagous species w as the highest on all dum ps, however on three investigated sites the proportion of panphytophages was higher, e.g. on the dum ps in Oświęcim, Bytom an d Bukowno. The proportion of m icrophytophages is considerably higher th a n panphytophages in m ore or less n a tu ra l biotopes. For example, N i e d b a ł a et al. (1981) observed the percentage of m icrophytophages from 79% in dry-ground forest to 97.3% in mixed forest. S k u b a ł a (1998) found m uch higher num ber of m icrophytophagous species, w hereas the proportion in the total num bers was identical for these two groups, in m ountain forests. It seem s th a t the analysed dum ps are in the last b ut one stage of the form ation of the mite community. As m entioned above it may be concluded th at the proportion of microphytophagous species will be increasing during next years as the envirom ental conditions will becom e m ore stable. F u rth er studies are necessary to have more detailed inform ation concerning the occurrence of m ites and driving forces responsible for the form ation of their com m unities. This knowledge m ay be very useful for reclam ation and conservation p u rp o ses. CONCLUSIONS 1. The investigations on oribatids on postindustrial dum ps have show n th a t it is im possible to describe a typical com m unity com m on to various dum ps. 2. Complex ecological conditions of these sites lead to a variety of species com binations.

Oribatida on postindustrial dumps 2 0 3 STRESZCZENIE [Tytuł: Zgrupow ania mechowców (Acari: Oribatida) na różnego typu zwałach poprzem ysłow ych. II. A naliza zoocenologiczna.] Do b ad ań nad zgrupow aniam i mechowców wybrano 5 zwałów poprzemysłowych w rejonie Górnego Śląska. Były to: zwał elektrowni węgla kam iennego w Jaw orznie, zakładów chem icznych w Oświęcimiu, zakładów cynkowych w Katowicach, h utnictw a żelaza w Bytomiu i kopalnictw a rud cynku i ołowiu w Bukownie. Wiek zwałów (około 30-40 lat) oraz stopień rozwoju szaty roślinnej (obecne drzewa lub krzewy liściaste) był zbliżony n a w szystkich stanow iskach. W pierwszej części arty k u łu ( S k u b a ł a 1997b) dyskutow ano zagęszczenie i bogactwo gatunkow e zgrupow ań roztoczy. Opisane zgrupow ania mechowców różniły się między sobą z uwagi na stru k tu rę dom inacji, skład gatunkow y, różnorodność gatunkow ą oraz udział grup roztoczy o określonych cechach ekologicznych. Zgrupowanie mechowców o najbardziej stabilnej strukturze opisano na nieużytkach galeno-galm anowych w Bukownie. Cztery gatunki Oribatida (Oppiella nova, Tectocepheus velatus, Liochthonius lapponicus i Quadroppia quadricarinata maritalis) spośród 108 występowały n a wszystkich zw ałach, a tylko dwa pierwsze osiągnęły wysokie zagęszczenie n a niektórych ze zwałów.
