Prey of the Persian Leopard (Panthera pardus saxicolor) in a mixed forest-steppe landscape in northeastern Iran (Mammalia: Felidae)

The results of a comprehensive analysis of the microelement composition of soils — B, Co, Cu, Mn, Mo, Ni, Zn and plants — Ag, Co, Cu, Mn, Mo, Ni, Pb, Zn (oak (Quercus robur L.), pine (Pinus sylvestris L.) perennial grasses — Kupena (Polygonatum multiflorum (L.) All.), wheatgrass (Elymus repens (L.) Gould)) of natural reserve belonging to different physical and geographical zones — Polessky reserve (mixed forest zone), Roztochya reserve (broad-leaved forest zone), Kanevsky reserve (forest-steppe zone), the reserve «Askania Nova» (steppe zone), the Chernogorsk massif of the Carpathian Biosphere Reserve (KBR, Ukrainian Carpathians), which are proposed to be considered as background. It was found that in the soils of mixed and broad-leaved forests and the Chernogorsk massif KBR with an increase in the content of gross forms of Co, Cu, Ni, Zn, the content of their mobile forms increases, this dependence is inverse in the soils of the steppe zone, which is associated with a decrease in soil acidity and mobility microelements A positive correlation was revealed between the humus content in soils and Zn, Co (gross and mobile forms) and negative — B, Mo in the soils of all reserve zones. It was found that the greatest biogeochemical activity is characteristic of plants in the zone of deciduous forests — oak leaves (Quercus robur L.) and pine needles (Pinus sylvestris L.).

The place of Ukraine in the systems of the biogeographic and ecoregion order of the world and the biogeographic organization of Europe are considered. The ecoregions are defined as objects of cross-border and international cooperation for protection and conservation of biodiversity and planning of global, regional and national natural protection systems. The review of ecoregions of Ukraine was proposed. 12 ecoregions were defined as existing on the territory of Ukraine. The terrestrial ecoregions are represented by European mixed forests, the Eastern European forest steppe, Pontic steppe, Crimean Submediterranean forest complex, Carpathian montane forests, Pannonian mixed forests. The freshwater ecoregions are represented by Central & Western Europe, Dniester – Lower Danube, Dnieper – South Bug, Crimea Peninsula, Don. The marine ecoregion plays an important role of the nature protection system of Ukraine. This ecoregion is the Mediterranean Sea Ecoregion. The Black and Azov seas belong to its composition. WWF has identified a list of Global 200 that contains 238 ecoregions (142 terrestrial, 53 freshwaters, 43 marine) priority for the protection of their habitat diversity and biodiversity. More than half of these ecoregions are marked as endangered. The habitats of two ecoregions from the Global 200 list are in Ukraine. These are the habitats of the terrestrial ecoregion European-Mediterranean Montane Forests (the mountainous territories of the Crimean and Carpathian regions) and the freshwater ecoregion Danube River Delta. The ecoregions of priority nature conservation in Ukraine are characterized. The features of international cooperation on the biodiversity conservation in these regions are analyzed. The Crimean sub-Mediterranean forest complex is designated as problematic ecoregion for international cooperation. The active participation of Ukraine in the international cooperation for the biodiversity protection in the Euro-Mediterranean mixed forest is outlined. The result of this collaboration is the transnational object «Ancient and Primeval Beech Forests of the Carpathians and Other Regions in Europe». The unique Crimean beech forests with oriental beech (Fagus orientalis), forest beech (Fagus sylvatica), and taurida beech (Fagus taurica) did not enter this object. International cooperation is not possible in annexed territories. Ukraine’s priority has identified the need to develop National Geospatial Data Infrastructure (NGDI). The NGDI is a prerequisite for fruitful international and eco-regional cooperation

The forest belt of the KuznetskyAlatau eastern macroslope consists of two subunits, namely the boreal-montane and the hemiboreal (sub)belts. In the upper one, the tall-herb communities of the class Mulgedio-Aconitetea are formed in place of the climax fir (Abiessibirica) forest. If being subject to regular mowing or grazing, these tall-herb communities are replaced by the «true» meadows of the ass. Trifoliopratensis—Alchemilletum vulgaris, order Arrhenatheretalia, whereas forest meadows of the ass. Trollioasiaticae—Poetumsibiricae replace the mixed forest composed of Pinussibirica, Piceaobovata, Betula pendula and a few of Larixsibirica in the lower subbelt. With the anthropogenic pressure increase, the «true» meadows of the ass. Filipenduloulmariae—Alchemilletum vulgaris and then of the ass. Potentilloanserinae–Alchemilletum vulgaris (Arrhenatheretalia) represent the next two digression stages, respectively. Forest meadows of the ass. Hesperidosibiricae—Poetumsibiricae, similar to those of the forest-steppe belt, are formed on dry sunny slopes in the bottom part of the hemiboreal belt.
