The fauna and population of Collembola in the Male Polissia agrocenoses
There was conducted analysis of taxonomic and synecologic structure of collembola' communoties
in five most widespread types of Small Polissya's agrocenosis, in particular, wheat, rape, soy, potato
and corn. It was discovered that explored communities of Collembola are characterized by their high
species riches (more than 49 species from 35 genera and 12 families) and for their variability of indexes
density, equalization of the population and species diversity. Under the influence of agricultural using
lands for arable were fixed many-sided and often not predicted changes of synecological structure of
collembolan cenotical communities. Separately, it was installed expansion of collembolan' mass circle
forms as part of agrogroups, comparatively with natural cenoses, appearance of specific dominants and
the emergence of different species' superdominance. It was conducted that in different types of Small
Polissya`s explored agrocenosis can potentially dominate 31 collembola`s species? to their total share
belong 75,1-100% of all coenotic groups` number. There were calculated and analyzed point alpha-
variety, coenotic alpha-variety, internallycoenotic beta-variety indices of Simpson, Berger-Parker,
Shannon and Shannon`s index of leveling. Spectra of collembolan' life forms are characterized by their
own specificity as in different types of agrocenosis, so in different variants for certain type. In structure
of collembolan' biotopic groups was noticed increase to 50% species' representation, which are resistant
to the dry environment. Also, explored agrocenosis are characterized by their sharp reduction of
hydrophilic collembolas` fraction in comparison with forest and meadow cenosis of explored district
(conducted 3 species from hydrophilled and hydromesophilled complexes. Analysis of collembola`s
life forms correlation showed that for species riches in explored agrocenosis most often prevail
representatives of upper lobe biomorph, 11-80,9% of coenotic variety. Similar structure of collembolas`
life forms` spectras is also noticed in forest, meadow and meadow-stewed biotops of latitudinal zones
of Ukraine`s broadleaf and mixed forests.
Keywords: biodiversity, Collembola, soil fauna, agrocenoses.
