Spiders (Araneae) of the northeast of the Luhansk Oblast (Ukraine).

Background: The dataset contains records of spiders collected in the northeast of Luhansk Oblast in the periods 1982-1989, 2009-2011 and 2021. It aimed at the inventory of spider fauna of the Striltsivskyi Steppe Nature Reserve and species distribution in the main grassland and forest habitats of the region. The research was also concerned with the impact of conservation management ‒ hay mowing or strict protection and man-induced steppe fire on spider communities.

The dataset of bat (Mammalia, Chiroptera) occurrences in Ukraine collected by the Ukrainian Bat Rehabilitation Center (2011-2022).

Background: Bats are of high conservational status in most European countries. All bats are under legal protection in Ukraine and included in the national Red Data Book. However, bats remain one of the least studied groups of mammals in Ukraine.

Genus (Ranunculaceae) in the Ukrainian Carpathians and adjacent territories.

Background: The dataset represents a comprehensive collection of occurrence records concerning the genus (Ranunculaceae) in the Ukrainian Carpathians and adjacent territories. It is based primarily on the results of critical revision of the main herbarium collections of the Carpathian region (i.e.

An Extended dataset of occurrences of species listed in Resolution 6 of the Bern Convention from Ukraine.

Background: The dataset includes georeferenced occurrences of species listed in Annex I of Resolution 6 of the Bern Convention and, partly, in the Red Data Book of Ukraine. The dataset was compiled within the work of NGO "Ukrainian Nature Conservation Group" aimed to prepare a Shadow list of Emerald Network (European network Areas of Special Conservation Interest) in Ukraine - newly proposed territories aimed at conservation of particular species and habitats mentioned in Resolution 4 and 6 of the Bern Convention. The list was prepared in 2017-2020 for expanding the already existing Emerald Network of Ukraine.

Reference-based checklist of gilled Agaricales (Basidiomycota, Fungi) from Ukraine.

Background: Agaricales is the largest order within the class Agaricomycetes (Basidiomycota, Fungi). Most genera have a gilled (lamellate) basidiomata, though gasteroid, secotioid and cyphelloid fruit bodies also occur in several families and genera. Although gilled Agaricales (usually called "agarics") are the most investigated part of the Fungi, the last summary of their diversity in Ukraine was published back in 1996 and needs to be updated.

Stochastic tools hidden behind the empirical dielectric relaxation laws.

The paper is devoted to recent advances in stochastic modeling of anomalous kinetic processes observed in dielectric materials which are prominent examples of disordered (complex) systems. Theoretical studies of dynamical properties of 'structures with variations' (Goldenfield and Kadanoff 1999 Science 284 87-9) require application of such mathematical tools-by means of which their random nature can be analyzed and, independently of the details distinguishing various systems (dipolar materials, glasses, semiconductors, liquid crystals, polymers, etc), the empirical universal kinetic patterns can be derived. We begin with a brief survey of the historical background of the dielectric relaxation study.
