Typical biotopes of the Danube meadows area are the Danube riverbed and its arm system, gravel-sand biotopes, floodplain forest biotopes, grassland biotopes and pastures. The Veľký Lél Island is a site of European importance. Until 2000, natural grasslands and floodplain forests were only fragments. The restoration of 20 hectares of neglected land...

Agricultural land is a more important resource biodiversity and changes in their dispersion and structures reflected the quality of habitats. A suitable bioindicator pointing to such changes is the taxon Araneae. The aim of our research was to point out the dispersion of Araneae individuals in the ecological and conventional farming conditions and...

Changes in the structures of abundance of Coleoptera reflect changes in the ecological status of their habitats. The aim of this research was to assess the dispersion of individual Coleoptera in ecological and conventional farming conditions and the influence of environmental variables (pH soil, potassium, phosphorus and nitrogen) on the abundance...

Database systems store data (big data) for various areas dealing with finance (banking, insurance) and are also an essential part of corporate firms. In the field of biology, however, not much attention has been paid to database systems, with the exception of genetics (RNA, DNA) and human protein. Therefore data storage and subsequent implementatio...

At present, when climate change has a negative effect on crop yield, good agricultural practices have a high importance via their direct influence on soil properties and biodiversity. The aim of this research was to assess the influence of ecotones and environmental variables (soil pH, soil moisture, K, P, N and soil temperature) on the abundance o...

Soil is an irreplaceable natural resource that enables the production of food and raw materials, forms agricultural and forest landscapes, filters and maintains water, ensures the cycle of substances in the ecosystem and contributes to maintaining biodiversity. Agricultural intensification is one of the most important factors for biodiversity loss....

Vplyv človeka na krajinu je čoraz výraznejší. Budovanie priemyselných areálov negatívne vplýva na lokálnu biodiverzitu, preto je dôležité, aby ľudia prispievali k jej návratu.

Morphological variability can be used as an indicator of the state of invertebrate populations. Microevolutionary processes can show up in the morphological differentiation of populations. This includes differences between morphometric characters in the two sexes. The variability of 12 populations of Bembidion minimum (Coleoptera, Carabidae) was as...

Soil arthropods respond sensitively to land management practices and correlate with beneficial soil functions. The aim of this research was to determine soil quality using the QBS index in different types of crops and influence of soil variables (pH soil, soil moisture, potassium, phosphorus and nitrogen) on soil arthropods. Between the years 2018...

In the country, agricultural land is an irreplaceable resource for the production of food and raw materials. Changes in the structure of epigeic groups reflect changes in the ecological status of habitats and response to the environmental pressure that affects them (e.g., intensification of cultivation, impact of herbicides and pesticides, agrotech...

Changes in the structures of epigeic arthropods reflect changes in the ecological status of their habitats. The aim of this research was to assess the influence of ecotones and environmental variables (pH soil, soil moisture, potassium, phosphorus, nitrogen) on the abundance of epigeic arthropods. Between 2018 and 2020, an investigation of differen...

The ground beetles Zabrus tenebrioides and Harpalus rufipes (Coleoptera, Carabidae) are two of the most prevalent pests of wheat and other grasses. This article presents current data on their distribution and the results of modelling the bioclimatic ranges of these species using the maximum entropy method. To improve the model, we used various RStu...

The effects of various aquatic habitats on the abundance, species richness, diversity and taxonomic distinctness of Odonata were studied. The impact of environmental factors and living conditions in lentic habitats were expressed by the composition of coenoses, on the evaluation we used the Dragonfly Biotic Index. The positive effects of habitat he...

Changes in the structure of epigeic animal groups indicate ecological stability, which are influenced by urbanization, agriculture, and forestry. The aim of the paper was to assess the impact of agrarian land in the vicinity of urban and suburban landscape and non-fragmented forest in the vicinity of rural landscape on the occurrence of epigeic gro...

In recent years, developments in the field of molecular biology and genetics have led to the increase in biological information stored in databases. The same increase in the volume of information occurred in the field of zoology, but the development of databases was not addressed in this area. We prepared a relational database and its diagram in th...

Changes in the structure of small mammals’ communities (Eulipotyphla, Rodentia) along urban–rural gradient indicate the environmental state of stability or instability. Since small mammals are important with regard to the transmission of diseases to man and domestic animals, therefore knowledge of their association with the landscape structure is n...

The species composition of a biota in an urban environment can greatly depend on the characteristics of local and surrounding habitats. Research on the composition of spider communities was carried out in a private garden, in various places - stored wood, under thujas, on a mown lawn, in an orchard and in a garden with crops, to identify habitat va...

The study concerns a monitoring survey of Cordulegaster bidentata Selys, 1843 (Odonata, Cordulegastridae), which is considered near threatened in the European Red List of Dragonflies, in order to show its habitat preferences and clarify the influence of slope and orientation of slopes on the occurrence of the species. Investigations of water habita...

Changes in the structure of ground beetle communities indicate environmental stability or instability influenced by, e.g., urbanization, agriculture, and forestry. It can affect flight capability and ellipsoid biovolume (EV) of ground beetles. Therefore, we analyzed ground beetles in various habitats. In the course of the period from 2015 to 2017,...

Urban areas are typical with a variety of heterogeneous environments as well as a wide range of habitats that have a great impact on animal species diversity. Urban architecture greatly enables the mass distribution of some animals. We evaluated the distribution of representative spiders (as the appropriate bioindicators) on city site conditions. H...

Ground beetles (Carabidae) were used to evaluate the bio indication environmental incidence. The ground beetle material (2,341 individuals, 30 species) was collected between 2015 and 2017 using pitfall traps in three types of forest habitats with different disturbance rates. The comparison of carabid’s sensitivity as bio indicators has been evaluat...

A trend of morphometric characteristic bioindication use and flight ability of the Carabidae is their valuation in relation to land use intensity. There are biotopes that are less disturbed, characterized by the presence of individuals that have a higher body average volume value, the so-called ellipsoid biovolume (EV), more than the presence of ap...

Changes in body size of living organisms can indicate changes in environmental quality. The family Carabidae is frequently used as an indicator of environmental status. We collected ground beetles in 9 Slovakian localities (in the Veporské vrchy Mts and the Juhoslovenská kotlina Basin) of various levels of disturbance, and evaluated the volume of i...

The Carabidae family (Coleoptera) is used frequently for its bioindication potential to detect the environmental burden. In 2013 and 2014, we studied the correlation of Carabidae on the biotopes of six areas in the Veporské vrchy Mts and the Juhoslovenská kotlina basin by using pitfall traps, Möricke plates and Bambara beetle traps. Out of 432 reco...
