Background. The spatial features of the structure earthworm communities in area influence motor vehicles were analyzed. Five species lumbricides belonging to three families found studied biocenosis located near M06 Kyiv–Chop motorway (Ukraine): Aporrectodea caliginosa (Savigny, 1826), A. rosea trapezoidеs (Dugesi, 1828), Lumbricus terrestris (Linnaeus, 1758) and Dendrobaena octaedra 1826). Materials Methods. Earthworms collected during 2021–2022 (Berezyna village, Zhytomyr region). material...

Abstract The Spanish slug, a species that is considered to be the most destructive pest among molluscs of Europe, reported spread widely across Ukraine during last 5–7 years. In addition its 5 known colonies in Western Ukraine, over 60 new localities from Western, Central, Northern, Southern and Eastern are for first time using own materials reports with photo general public. Newly include such major cities as Kyiv, Kharkiv, Donetsk, Khmelnitsky, Vinnytsia, Ternopil, Zhytomyr, Lutsk,...

Landsat satellite images (Landsat-5 for the period of 1990–2010 and Landsat-8 year 2020) were used spatiotemporal analysis dynamics main habitats Kozachelaherska arena (Nyzhniodniprovsky sands, Kherson region, Ukraine). The algorithm minimum distance automatic k-mean clustering was classification images. Habitats classified according to EUNIS principles. revealed a considerable decrease in summary area coniferous plantations 2000–2010. During last two decades, losses significantly exceeded...

The article describes the dynamics and causes of endemic human diseases in Ukraine. According to results statistical data on indicators anthropogenic technogenic load surrounding natural environment, ecological situation Ukraine is a crisis. This leads environmental pollution with substances dangerous health, deterioration Earth's ozone layer, also contributes appearance new chemical compounds changes quantitative composition existing ones.
 Endemic are those that observed people for...

The complex interaction of a man and the environment requires creation algorithms for predict- ing effects anthropogenic impact. This ecosystem models where all their basic elements relationships are taken into account. One most effective methods choosing informative differential system is development implemen- tation bio-indication models. Nowadays important task various effects. electrical transmission lines carry out specific integrated environmental It created on changes in under...

Based on the analysis of remote sensing data using GIS methods, peculiarities structure and spatial temporal dynamics land cover in territory Slovechansko-Ovruchsky ridge were determined, ridge's was carried out, relationship between characteristics landscape biodiversity established. For studied region, from Sentinel-2 spacecraft used. Preliminary processing classification satellite images performed Google Earth Engine cloud service. The automatic clustering algorithm k-mean method used to...

Human activity related to the exploitation or protection of environmental elements requires creation forecasts consequences involved. Such are not possible without construction models ecosystems and processes occurring in them. One critical modern forecasting dynamics is modelling their anthropogenic block. Our research aims develop methods for assessing transformation necessary state dynamics. In accordance with goal, we set ourselves following tasks: determine limits anthropotolerance...

The article describes the results of impact urbanisation on quantitative and qualitative structure earthworm communities, since is currently one main threats to biodiversity. Earthworms, as most common representatives edaphic mesofauna, react sensitively level environmental pollution. On example city Cherniakhiv, it has been established that lumbricide fauna studied area includes eight species: Aporrectodea caliginosa (Savigny, 1826), A. rosea trapezoides (Dugesi, 1828), Lumbricus terrestris...
