Succession of mite communities and bioindication. The knowledge on long-term
floristic transformation resulting from succession is relative lybetter known than that of
animal communities. The comprehensive analysis of faunal succession on the basis of
both vertebrate and invertebrate communities with theoretical background and
description of five types of succession (i.e. creative, stabilizing, rise-and-fall,
regressive and restorative) was conducted by Trojan et al. [28]. With regard to mite
communities, in Tilio-Carpinetum it was found that change of the abundance and
percentage in Oribatida and Mesostigmata was restorative, however, in case of the
latter group two increases and two falls were recorded (Table 5) [27]. Within oribatid
mite communities Oppiidae, Tectocepheidae, Achipteriidae and Mycobatidae
predominated in most of studied stands, however the latter family reached high
dominance only in 80 years old stand. Interestingly, Oppidaemore intensely inhabited
higher soil strata in younger stands while in older stands preferred more deeper strata.
On the other hand, Tectocepheidae and Achipteriidae in younger stands preferred the
litter while in older stands were more abundant in the first topsoil level (0-5 cm depth).
Tectocepheidae represented creative model of succession (abundance and dominance)
while in Achipteriidae it was regressive. In Gamasida communities Rhodacaridae
predominated in all stands (see also Table 4) but families typical in forest stands
(Parasitidae, Veigaiidae, Zerconidae) were also relatively abundant. Three latter
families intensively penetrated the whole studied soil profile, mainly inhabiting the
first topsoil level (with exception of the youngest stand where the litter was the most
intensively inhabited by these families). In Rhodacaridae it was evident that this family
prefer the two topsoil levels (0-5 cm and 5-10 cm depth) while in litter it was less
abundant. It is worthy to mention that in case of Parasitidae, Veigaiidae and Zerconidae
the abundance was negatively correlated with depth while in case of Rhodacaridae it
was the opposite. The Zerconidae represented restorative type of succession changes
(shaped by restorative changes of Zercon triangularis) while in Veigaiidaeit was
regressive. In the latter family the regressive trend was not found in the most abundant
Veigaia nemorensis which proves that the model of succession on the family level is
shaped by the set of species (apart from V. nemorensis) of this family found in Tilio-
Carpinetum (e.g. Veigaia cerva, Veigaia exigua, Veigaia decurtata,Veigaia sibirica).
