Understanding the factors governing grassland biodiversity across different spatial scales is crucial for effective conservation and management. However, most studies focus on single grain sizes, leaving the scale‐dependent mechanisms of biodiversity drivers unclear. We investigated how climate, soil properties, abiotic disturbance, and land use in...

Deadwood is one of the principal components of forest ecosystems. It completes numerous nature conservation and ecological functions. The work aimed to assess the reserves of woody detritus in the mixed forest of Slobozhanskyi National Nature Park (NNP) of natural origin. The research was carried out in an 86-year-old forest on fresh and fertile so...

The importance and significance of the conservation of the Emerald Object “The lower part of the Uda River Valley” (UA0000295) in botanical and general ecological aspects is discussed in detail. It is located on the outskirts of Kharkiv with an area of 13,381.0 ha. The studied area combines floodplains of regions occupied by meadows, shrub fragment...

The article examines the volume of coarse woody detritus in fresh maple-linden-dibrova in Slobozhanskyi National Nature Park. The study was carried out in 115-year-old forest with a predominance of common oak (Quercus robur L.) of natural origin on a sample plot (0.24 ha) by identifying and measuring of standing and lying dead wood components. The...

Ecological and coenotic properties are given and the environmental importance of natural complexes of the Emerald Network of Ukraine «Mozh river valley» (UA0000299 Mozh river valley) in Kharkiv region is highlighted. The object is located in the valley of the Mozh River — a right-bank tributary of the Siverskyi Donets River (Don River Basin) and co...

Dead wood is an important component of forest ecosystems. It performs a number of environmental functions. Coarse woody debris includes standing dead trees, fallen dead trees, fragments of fallen trees (trunks), branches (fragments of branches), and rough tree roots. It is a substrate and habitat for living organisms, including a number of species...

The environmental importance and significance ofthe emerald object «Roganka» (UA0000278) in thebotanical and general ecological aspects are shown.Its place is 2387.45 hectares and it includes the mainparts of the valleys of three left-bank branches (therivers Studenok, Rudka and Roganka) of the UdaRiver, which belongs to the basin of the SiverskyDo...

Forest typological and phytososological biodiversity of forest vegetation of Slobozhansky National Park is shown. The park covers 5244 hectares and includes the main parts of the run off valleys of the left-bank Merla River tributary, which belongs to the Vorskla River basin in the Kharkiv region. The main forest-forming species of the Slobozhansky...

The present research attempts to calibrate satellite images against field data on D. salina ß-carotene concentration expressed per 1 L of brine. We found the empirical relation between ß-carotene quantity and the index based on two infrared reflectance bands (NIR and SWIR).

Environmental aspects of tropho-metabolic activity of soil saprophages on the pH-buffering capacity of remediated soils in Ukraine was considered. Earthworm (Lumbricidae) casts have been proven experimentally to have a higher acid–base buffering capacity in comparison with that of the initial soil. Remediated soils enriched with earthworm casts bec...

The influence of reservation regime on agrochemical properties of chernozem and meadow soils of “Mikhailovska Tselina” Reserve was investigated. According to data of exchange capacity analysis these soils belong to non-salted category. The reservation regime influences on total humus in chernozem and meadow soils.
