Impact of red oak monoculture age on the ecological structure of the collembola taxocene
A comparative analysis of the Collembola taxon in a 20- and 48-year-old monoculture of invasive
red oak and native beech and hornbeam, which were planted in the Yaniv forestry in Roztochchia, was
carried out. These studies have shown that the density of the Collembola population increases
significantly with the age of the invasive stand. However, this figure is significantly lower than in
natural habitats. The total species richness in the Collembola taxa of a 48-year-old stand, compared to
a 20-year-old stand, increased by 1.3 times, and the habitat capacity at the level of point alpha diversity
increased by 2 times. The index of intra-cenotic β-diversity decreases by 1.5 times with increasing age
and is higher than in natural phytocoenoses. In the 48-year-old oak forest, a decrease in the main
diversity indices, namely the Shannon, Simpson and Margalef index, was also found. A comparative
analysis of the ecological structure and dominance structure of the studied taxa in natural and invasive
biocenoses also shows significant changes: in the 20-year-old oak, no eudominants were found, the
dominant species include 3 species that make up 61.8% of the total number, and 4 species are
subdominant (21.3% of the total number). In contrast, in beech, the absolute eudominant is 1 species,
which accounts for 39.7% of the total taxa. In the 48-year-old oak forest, one eudominant species with
an abundance of 40.1%, one dominant (23.8%) and three subdominants (15.4%) were found, while in
the hornbeam forest, no eudominants were found, three species are among the dominants and in total
account for 71.1% of the relative abundance of the studied taxon. Among the four identified biotope
groups, the proportion of forest species in 20-year-old oak forest is significantly increasing compared
to other biotopes. In terms of relative abundance in invasive and natural habitats, eutrophic species
prevail, which decreased in young oak compared to beech (53.1% and 60.9%, respectively), and
increased in old oak compared to hornbeam (58.9% and 44.9%, respectively).The taxon colembolus in
invasive oak monocultures of different ages is classified as eutrophic.
