Shpan-Koba Grotto is currently the only stratified Mesolithic and Neolithic site on the plateau of the First Range of the Crimean Mountains (Yayla). Lower Early Mesolithic cultural layers of the site (archaeological unit 3) have exceptional preservation due to the rapid accumulation of sediment and infrequent settlement of the grotto. Their planigraphy, number and composition of the artifacts can tell about the peculiarities of the economical use of the landscapes and rock shelter of the Crimean highlands at that time. Cultural layers of archaeological unit 3 date back to time from 11500 to 7600 years cal BP, which belongs to Early Preborial. At this time, the climate was colder and wetter than today, the plateau of the Yayla around Shpan-Koba was covered by mesofit steppes, pine, birch and juniper grew on the slopes of the mountains. According to archaeozoological data, the fauna of the Yayla included such representatives of steppe landscapes as saiga and horse, and simultaneously typical forest animals — red deer, brown bear and lynx. All cultural layers of the unit 3 are very similar. They belong to the type of "ephemeral": are represented by small fires, few bones of hunted animals and single flint artifacts. The layers were left by the bearers of the Swiderian culture, due to very few flint artifacts, among them: swidrian points, segment, backed blades, straight dihedral burin, end-scrapers. More than half of the found flint artifacts are retouched tools, the rest — blades and flakes, have the traces of use in the form of macro retouch. Such composition of the flint inventory indicates on the hunters (“expeditional”) character of the habitations in the Shpan-Koba grotto. The planigraphy of all layers of the unit 3 was similar too. It corresponds to classic ethnographical «Drop-Toss model» be L. Binford, which describe the organization of the living space around the hearth by a group of people from one to five people (Binford 1978; 1983). The central object in each of the cultural layers was one hearth about one meter in diameter with the thin charcoal lens and little piece of burned clay under it. Three concentric zones were traced around the hearths on the western, southern, and southeastern sides: 1) without artifacts; 2) with little bones and flint artifacts (Drop zone); 3) with bigger bones (Toss zone). The "asymmetrical" location of the finds in relation to the hearths indicates the absence of artificial housing in the grotto. The only exception is the habitation of the 3-5/6 cultural layer, in which a small wall of stones was excavated. For it, the "symmetrical" location of the finds around the hearths can be assumed to be an artificial structure made of plant materials, such as a brush windbreak or a hut. The windbreak could also exist in the habitation of layer 3-2, judging by the lack of a Toss zone in the south-western part. The presence of only one hearth in each of the cultural layers, the location of the artifacts relative to the hearth and their number, the composition of hunting prey, etc., evidence, that Shpan-Koba grotto in the Early Mesolithic was used as dwelling of little group (4—5 people). The occupation, probably, was very short terming, due to small and low-power fires, very few bones of animals and single flint artifacts, which were found in сertain layers. Their purpose was recreation, skinning and butchering of hunting prey, repair of hunting equipment and more. Seasonality of the Early Mesolithic dwellings in the grotto, due to archaeozoological data, fall on warm time — spring and summer (Benecke 1999, s 83, abb. 10). The aim of the swidrian people’s hunting expeditions to Yaila was hunting, first, on the saiga and red deer, which migrated from from the steppes of northern Crimea. The number of the red deer also increased in the First Range of the Crimean Mountains during warm seasons. The bones of the brown bear in many layers suggest that it was also an attractive prey. Key words: Crimea, Ukraine, Early Mesolithic, habitation, seasonal migrations, Swiderian.

Human–wildlife interactions (HWI) were frequent in the post-socialist period in the mountain range of Central European countries where forest habitats suffered transitions into built-up areas. Such is the case of the Upper Prahova Valley from Romania. In our study, we hypothesized that the increasing number of HWI after 1990 could be a potential consequence of woodland loss. The goal of our study was to analyse the effects of landscape changes on HWI. The study consists of the next steps: (i) applying 450 questionnaires to local stakeholders (both citizens and tourists) in order to collect data regarding HWI temporal occurrences and potential triggering factors; (ii) investigating the relation between the two variables through the Canonical Correspondence Analysis (CCA); (iii) modelling the landscape spatial changes between 1990 and 2018 for identifying areas with forest loss; (iv) overlapping the distribution of both the households affected by HWI and areas with loss of forested ecosystems. The local stakeholders indicate that the problematic species are the brown bear (Ursus arctos), the wild boar (Sus scrofa), the red fox (Vulpes vulpes) and the grey wolf (Canis lupus). The number of animal–human interactions recorded an upward trend between 1990 and 2018, and the most significant driving factors were the regulation of hunting practices, the loss of habitats, and artificial feeding. The landscape change analysis reveals that between 1990 and 2018, the forest habitats were replaced by built-up areas primarily on the outskirts of settlements, these areas coinciding with frequent HWI. The results are valid for both forest ecosystems conservation in the region, wildlife management, and human infrastructures durable spatial planning.

AbstractIran lies at the southernmost range limit of brown bears globally. Therefore, understanding the habitat associations and patterns of population connectivity for brown bears in Iran is relevant for the species’ conservation. We applied species distribution modeling to predict habitat suitability and connectivity modeling to identify population core areas and corridors. Our results showed that forest density, topographical roughness, NDVI and human footprint were the most influential variables in predicting brown bear distribution. The most crucial core areas and corridor networks for brown bear are concentrated in the Alborz and Zagros Mountains. These two core areas were predicted to be fragmented into a total of fifteen isolated patches if dispersal of brown bear across the landscape is limited to 50,000 cost units, and aggregates into two isolated habitat patches if the species is capable of dispersing 400,000 cost units. We found low overlap between corridors, and core habitats with protected areas, suggesting that the existing protected area network may not be adequate for the conservation of brown bear in Iran. Our results suggest that effective conservation of brown bears in Iran requires protection of both core habitats and the corridors between them, especially outside Iran’s network of protected areas.
