Vertical distribution of collembola, lumbricidae and elateridae in alluvial soils of floodplain forests

Biodiversity of Floodplain Soils in the European North‐East of Russia

“…Complexes of hemi-and euedaphic species are not much change from year to year and so form a stable part of Collembola group whereas epigeic species are most mobile in alluvial forest soils [9]. Collembola occupy upper soil horizons with high organic matter content and they are not found at depths under 20 cm from soil surface [10]. The population density of springtails varies during vegetation period and observation years [9].…”

“…But soil invertebrates can essentially increase taxonomic and species diversity in alluvial meadow-boggy soil (Plot 3) at warming autumn. This happens due to available fresh plant waste, low ground waters level, low moisture degree of upper soil horizons and, consequently, formation of appropriate ecological conditions for both soil fauna and microbiota [10]. High number and functional activity of bacteria at Plots 2 and 3 along with high number of meso-and macro-fauna leads to active mineralization of forest litter not only in alluvial soddy soils but also in alluvial meadow-boggy soils at interridge depressions in the second half of vegetation period.…”

“…This was conditioned by the fact that floodplain soils were treated as to be used in engineering and agriculture. In the twenty-first century, floodplain landscapes gained high attention in both Russia and European countries [7][8][9][10][11][12]. These studies aim at identifying the dependence in population number of soil organisms from flood regime [13][14][15]; adaptations of invertebrates to moisture deficient or excess [16][17][18].…”

“…At the same time, priority attention of ecologists has been paid to the identification of biodiversity and structure of soil biota in the coniferous forests occupied watersheds [22][23][24]. Alluvial soils of the northern river floodplains are studied fragmentarily in this respect, particularly soil biota of floodplain aspen-birch forests [9,10]. This was conditioned by the fact that morphological and physico-chemical properties of alluvial soils as well as ways of preservation and increase of soils fertility of floodplain meadows were studied firstly at the European northeast of Russia.…”

The cold-adapted population ofFolsomia manolachei(Hexapoda, Collembola) from a glaciated karst doline of Central Europe: evidence for a cryptic species?

“…Both species are among the most abundant soil collembolans in Central Europe. F. manolachei is associated with warmer and drier habitats, while F. quadrioculata, often classified as a hydrophilous species, preferring colder and wetter soils (Pichard et al 1989;Ponge 1993;Potapov 2001;Cassagne et al 2004;Kov a c et al 2005;Fjellberg 2007;Raschmanov a et al 2008;Kolesnikova et al 2013;Sterzynska et al 2014).…”
