AB  - Throughout Europe agriculture intensification during the last decades has dramatically changed the structure of the farmland landscape with an intensive impact on ecosystem stability. Changes in the production led to decreased habitat heterogeneity and to decline in biodiversity, including the European hare (Lepus europaeus), especially in the lowland regions. Even though European hare mostly adapted to intensive agricultural habitats, the population densities have decreased throughout Europe since the 1960s. Previous research reported field size to be one of the most important predictors of the hare population. We aimed to assess the effect of habitat heterogeneity and structure on hare habitat selection i.e. population density. Using hunting organization census data we explored the population density and habitat preference of the European hare in spring 2020 in the hunting ground, Ba & ccaron;ka - Ba & ccaron;ki Petrovac. The average population density of European hare significantly differed between four fractions of the hunting ground - Ba & ccaron;ki Petrovac, Kulpin, Glo & zcaron;an, and Magli & cacute;. Density varied from 27 in Ba & ccaron;ki Petrovac to 50 individuals per 100 ha in Magli & cacute;. The population was negatively affected by mean patch size and by the area under no vegetation during the winter period. Conservation measures should focus on enhancing habitat heterogeneity by reducing field size, and fostering sowing during the late autumn period.

AB  - Derivatives of thiocarbohydrazone studied so far have shown great biological activity such as antioxidant, antimicrobial, and anticancer. Most of these compounds are bis-substituted derivatives, while monothiocarbohydrazones are much less investigated. Eighteen monothiocarbohydrazones were synthesized and subjected to physicochemical characterization in order to facilitate the examination of their potential biological activity and application in future studies. The structure of synthesized derivatives was confirmed with NMR and FT-IR spectroscopy, and with elemental analysis. For one of the compounds, single-crystal X-ray diffraction analysis was performed. Specific and non-specific molecular interactions were interpreted by LSER principles, using Catalan's model. For additional information about the dominance and influence of the interactions presented, correlations with Hansen's solubility parameters were calculated. Influence of the type and position of the substituent on absorption maxima was determined with LFER (linear free-energy relationship) principles, using Hammett's equation. Acidity constants of the synthesized compounds were theoretically calculated and experimentally determined. Moreover, the excitation of a molecule by a photon of UV-Vis light was interpreted by time-dependent density functional theory (TD-DFT) calculations of UV absorption bands, and intramolecular charge transfer (ICT) was quantified by calculations of the charge transfer distances (D-CT).
