The aim of the study. The aim of the study was to reveal regularities in the development of ground beetles (Coleoptera, Carabidae)’ communities, to determine their species peculiarities as dependent on soil formation rate and soil ecology in the ecosystems developed on the terminated fly ash dump of the thermoelectric power station over nine years of restoration. Location and time of the study. The main object of the study was a terminated fly ash dump No.1 of the thermoelectric power station No.5 in Novosibirsk, Russia. (54°59' NL, , 83°03' EL). Soil samples were collected in 2019, whereas the ground beetles were collected in 2017 and 2019. Methodology. Six study sites, corresponding to the fly ash dump sedimentation zones, were chosen. The undisturbed white birch forest and clover-brome meadow were chosen as controls representing mature climax ecosystems. Soil cover, developing on the fly ash dump after its termination, was described according to the soil classification of technogenic landscapes, and was shown to consist of various types of embryozems (Technosols). Soil water content on each study site was measured in 0–5cm layer by gravimetric method. Soil samples were collected in May 2019. To collect ground beetles five traps were placed on each study site, each trap filled up to 1/3 of its volume with 4% acetic acid for fixing the trapped beetles. The beetles were collected in May–June 1017 and in June–July 2019. The data obtained were used to calculate α-biodiversity indices and perform cluster analysis using PAST v.3.09 software. Main results. Altogether 74 species of the ground beetle we found: 60 species of ground beetles were identified in the revegetating fly ash dump areas, with 48 species found at the sites amended with potentially fertile substrate (PFS), and 35 species found at the sites without PFS addition. The control sites under birch forest and meadow had 14 and 10 species, respectively. Thus the ground beetles’ abundance in the reclaimed area was almost 3 times greater than in the non-reclaimed area (973 specimens vs. 347). Cluster analysis discriminated three groups in the studied fly ash dump sites, namely dry non-reclaimed sites, dry PFS sites and moist sites. Soil cover of the studied fly ash dump was represented by initial, organic matter accumulating, humus-accumulating and sod embryozems (Technosols). Conclusion. Over nine years of spontaneous restoration at the terminated fly ash dump of the thermoelectric power station species rich and abundant communities of ground beetles were formed. These communities differed significantly from those at the adjacent undisturbed climax ecosystems used for comparison. Species richness and dynamic density of ground beetles was shown to increase from the control sites to non-reclaimed sites and PFS-reclaimed sites. The autonomous position in the catena was found to be occupied by the less evolutionary developed embryozem type, whereas downwards along the catena, i.e. with increasing soil moisture content, identified soil types belonged to higher evolutionary order. Therefore technical recultivation with fly ash dump overlaying with potentially fertile substrate or fertile soil allow accelerating soil cover development, as well as the development of an entire biogeocenosis.

Background. The aim of the study was to assess the composition and structure of bacterial assemblages by estimating 16S rRNA gene sequences diversity in a young Technosol, developing on a revegetating fly ash dump. Location and place of the study. Two soils were chosen for the study in the environs of the thermoelectric power station No.5 in Novosibirsk region: 1) nine years old Technosol (54°59' NL, 83°03' EL), developing on the spontaneously revegetating fly ash dump, and 2) Phaeozem under undisturbed white birch forest (55°00' NL, 83°04' EL). Soils were sampled from the 0-5 cm layer as three individual replicates each. Materials and methods. The total DNA extracted from soil samples was used as a matrix for PCR amplification using V-3-V4 primers for 16S rRNA genes. The obtained amplicons were sequenced on Illumina MiSeq platform in the Genomics Core Facility of the Institute of Chemical Biology and Fundamental Medicine SB RAS (Novosibirsk, Russia). Descriptive statistics and principal components analysis were used to analyze and present the data. Results. Overall 4887 different operational taxonomic units (OTUs) were found at the 97% similarity level; the OTUs were ascribed to 306 genera, 212 families, 123 orders, 84 classes and 32 phyla of bacteria domain. At the phylum level bacterial assemblages in both soils were dominated by Proteobacteria, Acidobacteria and Actinobacteria, showing rather similar outline of the phyla relative abundance, confirming the direction of pedogenesis towards Phaeozem. Higher abundance of Chloroflexi a physiologically diverse phyla with aerobic and anaerobic thermophiles, anoxigenic phototrophs and anaerobes, able to respire organic halides, in the young Technosol complies with harsh edaphic conditions there. Although the relative abundance of Rhizobiales, Actinomycetales and unclassified Acidobacteria_Gp6 and Acidobacteria_Gp3 was found to be 1.5–2.4 times higher in the undisturbed Phaeozem, they also were predominating in the Technosol samples. The α-biodiversity indices, pertaining mostly to species/OTUs richness, i.e. Chao-1, OTUs number, Margalef, Fisher’s alpha, were higher in Phaeozem, whereas evenness and equitability were higher in Technosol. Both soils demonstrated similar Shanno indices, which were rather high (6.3). Conclusions. Nine years of spontaneous revegetation on the terminated fly ash dump of the thermoelectric power station resulted in the development of the Technosol, containing quite rich and diverse bacterial assemblage, which was rather close in structure at the phylum taxonomic level to the adjacent undisturbed Phaeozem. Overall the early stages of pedogenesis were dominated by specific bacterial assemblage (Chloroflexi, Xanthomonadales, Geobacter, Aciditerrimonas, Iamiaceae and some others), performing weathering of the pedogenic substrate, i.e. fly ash. The present of nitrificators (Nitrospira), denitrificators денитрификаторов (Reyranella) together with diazotrophs (Bradyrhizobium, Rhizobiales) dominance evidences the establishment of the entire network of nitrogen transformation process already at the early stages of revegetation of the fly ash dump. Large percentage (17%) of Bacteria, the information about which ribosomal gene sequences is most likely absent in the respective data bases necessitates more detailed research into the soil microbiome on fly ash dumps.

AbstractThe effects on carabids of natural, fescue, and rye sod types and of tillage were investigated in a pest management apple orchard. Carabids were sampled before and after the treatments by pitfall trapping and by two types of soil sampling. There were no significant effects of sod type on pitfall trap catches; however the abundance of all common species in soil samples was significantly affected by sod types. Usually in soil samples carabids were most abundant in natural sod and least abundant in tilled plots; numbers were intermediate in fescue and rye. Sod type did not affect structure or diversity of the carabid fauna.

In this study, fly ash was obtained from Matla power station and the physicochemical properties investigated. The fly ash was characterized by x-ray fluorescence, x-ray diffraction, scanning electron microscopy, and inductively coupled plasma mass spectrometry. Surface area, particle size, ash and carbon contents, pH, and point of zero charge were also measured. The results showed that the fly ash is alkaline and consists mainly of mullite (Al6Si2O13) and quartz (SiO2). Highly toxic metals As, Sb, Cd, Cr, and Pb as well as metals that are essential to health in trace amounts were also present. The storage and disposal of coal fly ash can thus lead to the release of leached metals into soils, surface and ground waters, find way into the ecological systems and then cause harmful effect to man and its environments.

Abstract The aim of this study was to identify the role of field margin habitats in preserving the diversity and abundance of ground beetle assemblages, including potentially entomophagous species and those with conservation status in Poland. Research material was collected in 2006–2007 in four types of margin habitats – a forest, bushes, ditches and in two arable fields. Insects were captured into pitfalls, without preservation liquid or bait added to the traps. Traps were inspected twice a week, between May and August, and one sample was a weekly capture. In field margin habitats the most abundant species were Limodromus assimilis, Anchomenus dorsalis, Pterostichus melanarius and Carabus auratus. A lower abundance of species was noted on fields, with dominant Poecilus cupreus and P. melanarius. The group of zoophagous carabids found in our study includes 30 species from field margin habitats, i.e. 37.5% of all captured Carabidae taxa and 58.3% of all specimens. The share of aphidophagous species was 84.9% among bushes, 86.7% near ditches, and 88.0% in the forest habitat. Several species captured during the study are under protection in Poland. These include the partly protected Carabus convexus, which also has the status of near threatened species, the partly protected Calosoma auropunctatum, and Broscus cephalotes. Considering all the investigated field margin habitats, ground beetles were most numerous in the oak-hornbeam habitat, defined as bushes, formed predominantly by Prunus spinosa, Crataegus leavigata, Sambucus nigra and Rosa canina. Thus, this habitat was the most important reservoir/refugium for the ground beetles.

The Ground beetles occurrence in agricultural areas can contribute to pest control as well as indicate environmental quality. This study aimed to evaluate the composition of the Carabidae community in an agricultural area of annual crops. Ninety-six pitfall traps were installed in a grid 10 meters apart. The experimental area had one hectare in a double-cropping system of soybean (summer) and corn (autumn-winter) followed by a fallow period. Ground beetle composition analysis was performed using ANAFAU software. We collected 42 species and 1537 specimens of Carabidae distributed in 14 tribes. Harpalini tribe was the most common compared to the others. Were considered predominant, in the fauna analysis, the species Calosoma alternans granulatum Perty, 1830, Selenophorus discopunctatus Dejean, 1829, Selenophorus alternans Dejean, 1829, Selenophorus sp.1, Tetracha brasiliensis (Kirby, 1819), Abaris basistriata Chaudoir, 1873 and Galerita collaris Dejean, 1826. Thus, a diverse and abundant Carabidae community was identified in that cropping system.

In a region located mainly in the State of San Luis Potosí, México, floristic and soil samples were taken, in order to obtain palynological spectra. The comparison between the floristic results and the palynological spectra corresponding to eight types of vegetation, shows that there are taxa such as Pinus and Quercus with a high pollen representation (RP) in most of the spectra. There were some, such as the grasses that exhibited a normal RP. Also, low values of RP were detected in some taxa typical of sucrubland. A cluster analysis was applied to forty-seven soil samples and yielded a clear separation between a) oak forest and chaparral, and b) other vegetation types.

AbstractWhile much of global biodiversity is undoubtedly under threat, the responses of ecological communities to changing climate, land use intensification, and long-term changes in both taxonomic and functional diversity over time, has still not been fully explored for many taxonomic groups, especially invertebrates. We compiled time series of ground beetles covering the past two decades from 40 sites located in five regions across Germany. We calculated site-based trends for 21 community metrics representing taxonomic and functional diversity of ground beetles, activity density (a proxy for abundance), and activity densities of functional groups. We assessed both overall and regional temporal trends and the influence of the global change drivers of temperature, precipitation, and land use on ground beetle communities. While we did not detect overall temporal changes in ground beetle taxonomic and functional diversity, taxonomic turnover changed within two regions, illustrating that community change at the local scale does not always correspond to patterns at broader spatial scales. Additionally, ground beetle activity density had a unimodal response to both annual precipitation and land use. Limited temporal change in ground beetle communities may indicate a shifting baseline, where community degradation was reached prior to the start of our observation in 1999. In addition, nonlinear responses of animal communities to environmental change present a challenge when quantifying temporal trends.
