Te Waipounamu/South Island is located along the modern northern margin of the strongest SWW, but there are no continuous high-resolution records of westerly wind variability and hydroclimate that extend back to the end of glaciation from this region. Here, we present a multi-millennial to multi-centennial reconstruction of hydroclimate and westerly wind intensity for southern Aotearoa New Zealand using a sediment core from Lake Von in Central Otago that spans the last ∼16,000 years. Higher lake levels and an expanded lake extent are caused by cooler and wetter climate conditions under more intense westerly wind flow. Conversely, a reduction in westerly wind intensity results in a warmer and drier climate, lower lake levels and migration of the shoreline towards the lake depocenter. There are seven episodes of low lake level between 11100 and 3500 cal yr BP that occur within two broad intervals between 11100 and 8300 cal yr BP and 6000–3500 cal yr BP. There are three periods of relatively high lake level between 12500 and 11200 cal yr BP, 8300 - 6000 cal yr BP, and 3500 cal yr BP to present. Multi-millennial to multi-centennial fluctuations in hydroclimate and westerly wind intensity at Lake Von are replicated by records across the Pacific Basin in southern South America showing synchronous hemisphere-wide shifts in westerly wind intensity through time.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"735 ","pages":"Article 109826"},"PeriodicalIF":1.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144107294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents results of fossil small mammals' investigation in cultural layers of six Late Pleistocene sites related to Middle and Upper Palaeolithic. In addition to prehistoric sites at Betovo, Khotylevo 2, Eliseevichi 2, Yudinovo, Novgorod Severskaya, and Byki 7, we analyse two synchronous Late Pleistocene natural faunal localities in Arapovichi and Troitsa 2, all in the centre East European Plain. The main aim of this paper is to reconstruct the transition of the regional small mammal fauna from the end of MIS 3 (the so-called Bryansk = Denekamp Interstadial) to the Last Glacial Maximum (LGM) of Marine Isotope stage 2 (MIS2) (∼32–17 ka BP). All small mammal assemblages show low species richness (3–16 taxa), with cold adapted tundra and steppe animals dominating, while forest mammals are rare or practically absent. Palaeozoological data indicate the existence of mosaic periglacial landscapes in the area, such as complicate composition of shrub tundra-like and periglacial steppe. The three-dimensional descriptive model reproduces changes in local faunal (LF) composition caused by the general climate trend during the transition from interstadial conditions at the end of MIS3 to the extremely cold conditions of the LGM (mid-MIS2). We distinguish four main phases of this transformation: phase I that corresponds to the end of MIS3 and the beginning of MIS2 and is characterised by the dominance of <em>Dicrostonyx</em> sp., relatively low occurrence of <em>Lasiopodomys anglicus/gregalis</em>, low occurrence of <em>Ochotona pusilla</em>; the next phase II is characterised by some decrease of <em>Dicrostonyx</em> sp. remains but the increase of <em>L. gregalis</em>. Phase III corresponds to the most severe climatic conditions in the GS-2.1 stadial.

However, late Holocene landscape change in the peatlands of southeastern Anatolia is currently not well understood. This environment is important to protect as a valuable carbon sink with many endemic plant species and a rich biodiversity. This study, which was carried out in the Gölbaşı depression in southeastern Anatolia, aimed to investigate vegetation changes during the Late Holocene and to evaluate human impact on the landscape. Late Holocene studies conducted in Anatolia have demonstrated an increase in aridity especially in continental regions and that this was a warmer period in general. Palaeovegetation studies indicate that the effects of human activities on vegetation in Anatolia have been considerably more pronounced during the last two millennia of the Late Holocene. In this study we have investigated how human activities have influenced vegetation change during the Late Holocene in the Gölbaşı basin, which is one of the eighteen largest peatlands in Anatolia, and located in a transition area between Mediterranean and continental climate regions. A sediment core (GLBS21) was taken from the Gölbaşı peatlands region and analysed for fossil pollen as a proxy for vegetation change. The arboreal pollen (AP) to non-arboreal (NAP) pollen ratio in the study area is 56 % AP and 44 % NAP indicating a semi-open landscape. According to the fossil pollen record, <em>Pinus</em>, <em>Cedrus</em>, <em>Juniperus</em>, <em>Quercus cerris</em> types are the most common tree species, and <em>Artemisia</em>, Asteraceae, Amaranthaceae, Poaceae and <em>Plantago</em> are common herbaceous pollen types. The high representation of non-arboreal pollen known to be associated with human impacts, such as <em>Artemisia</em>, <em>Plantago</em>, and Cerealia type, and the presence of arboreal pollen associated with cultivation, such as <em>Castanea</em>, <em>Juglans</em>, and <em>Pistacia</em>, indicate that human land use has played an important role in shaping this landscape. The record from Gölbaşı highlights the sensitivity of this region to changing human activity, for example, reforestation is evident following abandonment associated with plague that affected Anatolia in the 14th-15th century. The record also reveals continued agricultural activity during periods of conflict. The fossil pollen record emphasizes the resilience and changing character of this landscape.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"732 ","pages":"Article 109806"},"PeriodicalIF":1.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143881907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
