The article presents the results of a taxonomic study of the archaeozoological collection from the Zolotoye 1 settlement. The settlement is located in the steppe zone of the Tobol-Ishim interfluve (the Polovinsky District of the Kurgan Region). A significant part of artefacts, including bone remains, belong to the Alakul culture of the Late Bronze Age (17th–16th centuries BC). A small collection (a total of 6 fragmented vessels) attributed to the Alek-seyevka-Sargary culture was also identified. The relevance of this work is determined by the fact that data on the species composition of Alakul archaeozoological collections are predominantly obtained from necropolises, whereas economic characteristics are primarily reflected by materials from the settlements. The study in question was conducted using the paleozoological method. The taxonomic affiliation of bones was determined using the reference collection of skeletons from the Zoological Museum of the Institute of Plant and Animal Ecology UB RAS along with corresponding atlases. The conclusion about the taxonomic affiliation of fossil remains was based on the similarities in composition and size between the morphological structures of bones. The age of the indi-viduals was determined by the degree of tooth abrasion and by the attachment of the pineal gland. The studied osteological collection includes 2783 items. In order to define the features of its occurrence considering species composition, a planigraphic analysis was performed. To this end, we used data collected from a digital total sta-tion and field inventories. As a result, it was found that the bone remains belong mainly to domestic animals (99.5 %). Cattle bones (47 %) predominate, followed by the bones of small cattle (34 %) and horses (18 %). Jud-ging by age characteristics, cattle were kept for the production of milk and meat. The remains of wild animals are scarce (0.5 %). They include commercial species (elk, hare, waterfowl), which indicates that the Alakul population was engaged in hunting. The comparison of domestic and wild animals, the composition of the herd from the Zolotoye 1 settlement located in the interfluve area with the archaeozoological collections of the Late Bronze Age from the forest-steppe Trans-Urals revealed their similarity, first of all, with Alakul materials originating from the layer of settlements confined to river systems. This fact reflects the general line of development in livestock breeding of the period under consideration, which suggests that the carriers of the Alakul culture developed stable forms of adaptation to different living conditions.

The paper reports on the results of experimental-traceological study of stone tools used for metal forging by the Late Bronze Age population of the Middle Tobol River region (Western Siberia). The chronological span of the study, according to the radiocarbon dating, extends from the 17th to 9th centuries BC. This paper aims to substan-tiate and expand the existing knowledgebase on the metalwork production with the aid of experiments in forging copper and bronze. The research materials include about 60 stone tools from the Late Bronze Age sites and 23 experimental tools. The trace evidence analysis and microphotography of the signs of use-wear have been performed using a continuous-zoom microscope MC-2 ZOOM with 10х to 40х magnification and a Canon EOS-1100-D camera. The experimental study involved cold and hot forging of copper and bronze items with different tin content and their surface smoothening. As a result, the efficiency of the stone tools in molding has been con-firmed. The signs of use-wear of the tools have been recorded. Distinctive use-wear features of hammers for cold and hot forging associated with the tool kinematics have been identified. It has been concluded that the wear signs on the hammers used for incomplete hot and hot forging were identical. It appeared that the smooth working area of some flatters was the result of preliminary abrasive treatment. Smoothening and drawing proved efficient in processing of copper items and low-alloyed bronzes. This treatment was carried out on the hot metal. It has been ascertained that the kinematics of processing of the copper and bronze items was the same. The signs of usage of the tools employed for shaping bronze moldings with different tin content differ from those on the tools used on copper by more extensive chipping, which is due to a higher hardness of tin-copper alloys. Prototype multi-functional tools used in different operations, viz., forging and drawing, have been identified. Their specific is the working area with a combination of several groups of wear marks overlapping each other. Therefore, we managed to produce a series of the experimental tools used in copper and bronze forging. This allowed us to elaborate the functional identification and technology of some archaeological instruments from the Late Bronze Age sites of the forest-steppe Tobol River region.

The research is devoted to the study of poorly preserved psammophytic variants of meadow steppes in the forest-steppe zone of the Middle Volga Region. It has allowed to define the main stages of re-establishment of vegetational cover and estimate the conservation prospects on the river Ardym in different ecological conditions (geomorphological and edaphyc). It has been established that the re-establishment of psammophytic steppes vegetation occurs in a similar way both on the slopes of the predominantly southern exposition and on watershed surfaces. However, in the absence of anthropogenic effects on watershed surfaces, there is a sylvatization of the vegetation cover resulting in displacement of psammophytic steppes. Only the constantly occurring weak natural erosion processes on the slopes of the predominantly southern exposition contribute to the preservation of these rare communities here. Under intense anthropogenic influence, as well as in the conditions of a significant erosion process, the psammophytic steppes fail to be preserved or replaced by steppe meadows.
