To fill this gap, we provide new insights into the early exploitation of olive trees in Eastern Sicily (Italy) since the Early-Middle Bronze Age (18th cen. BCE, 3700 BP), through the integration of novel high-resolution palynological analyses of lake sediments at Pantano Grande (a.k.a.

The study site is located along the Messina Strait: a trade and transit route used by seafarers to enter the Tyrrhenian Sea from the Eastern Mediterranean since prehistory. Vegetation changes, including the propagation of olive trees and other forms of land-use or rewilding, are found to be coincident with changing socio-cultural patterns over the last 3700 years. Our results suggest anthropogenic propagation of olive trees coinciding with three cultural stages: (i) Early-Middle Bronze Age (Castelluccio and Thapsos cultures); (ii) Roman times; (iii) Late Modern times (Kingdom of Sicily). This paper establishes an earlier date than previously recognized for the beginning of landscape transformations driven by olive tree exploitation in Italy, representing the second oldest evidence in the Central Mediterranean. We hypothesize that cultural exchanges between Sicily and the Aegean in the Early-Middle Bronze Age have promoted the use of wild olive trees in the Messina area. At that time, olive trees could have been used for various purposes, including fruit production, but also wood and forage for animals. The development of olive groves followed a gradual, multi-stage process in the Central Mediterranean, with large-scale cultivation appearing only in modern times.

Understanding past trajectories of change provides knowledge of how modern landscapes emerged, which can be valuable for their sustainable management. The aim of this study is to reconstruct environmental change in Western Anatolia (Turkey) through palaeoecological analysis of sediment from Buldan Yayla Lake (Denizli-Buldan) from the Last Glacial Maximum (LGM) to the present, using a high-resolution and multi-proxy dataset. To this end, fossil pollen, micro-charcoal, non-pollen palynomorphs, micro (μ)-XRF and radiocarbon analyses were applied to an ∼18 m sediment core from Buldan Yayla Lake (Denizli-Buldan). According to the fossil pollen record, forest presence was low during the LGM (21000-18000 cal. BP), with the lowest value recorded at 5 % during this period due to cold and dry climatic condition. Forest presence began to increase with the transition to the Post-LGM period. Rapid forest development and high forest presence were observed in the lake record from the transition to the LGM until the late Holocene. Forest development in Western Anatolia occurred approximately 4,000 years earlier than in Europe according to the age-depth model developed for this record, though if a hiatus exists, this could reflect a shift of at least 1,300 years. High forest abundance during the late Glacial period was interrupted during the Younger Dryas (YD) and during the dry climatic periods of 9250–8900 and 7700 cal. BP. The late Holocene period was characterized by intensive land use, specifically olive cultivation, which reached its highest level in the Roman Imperial Period (during the ancient city of Tripolis era), and the highest olive percentage recorded in Anatolia (38.4 %) was reached. Forests were generally dominated by oaks, with pine forests replacing oak forests in the last 1350 (cal. BP) years. Micro-charcoal and non-pollen palynomorph data were low in concentration between the LGM and Holocene and began to increase with the Holocene transition reaching their highest values during the late Holocene. This study provides a reconstruction of long-term environmental change in Western Anatolia and reveals a significant relationship between climate variability and shifts in vegetation patterns, particularly highlighting the increasing frequency of fires and changes in land use during certain periods. This finding serves as an important example for understanding the relationships between climate, vegetation, fire, and land use in the Mediterranean Basin.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"356 ","pages":"Article 109296"},"PeriodicalIF":3.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This question requires a deep understanding of the long-term correlation between temperature and monsoon rainfall changes. We selected Yunlong Lake, a climate-sensitive subalpine lake located on the southeastern margin of the Tibetan Plateau, to study this issue. We semi-quantitatively revealed warm-season temperature changes using the relative abundance of warm-preference planktic diatoms, namely <em>Achnanthidium catenatum</em> and <em>Aulacoseira granulata</em> var. <em>angustissima</em>, found in our diatom seasonal survey. Meanwhile, by examining the spatial pattern of surface diatom assemblages along the water depth gradient, two diatom-water depth transfer functions were constructed by using the modern analogue technique (MAT) and weighted average partial least squares regression (WAPLS) method, which were used to quantitatively reconstruct past lake water level changes. Comparison with independent modern monitoring records, the warm-water diatom indicators and the two diatom transfer functions suggest to be sensitive and reliable for reconstructing long-term temperature and rainfall changes in the Indian Monsoon domain. Based on this, and relying on the complete Holocene sedimentary records from the profundal zone of the lake, we reconstructed the warm-season temperature changes and lake water level fluctuations during the Holocene. Our reconstruction indicates that the temperature and rainfall in the Indian Monsoon domain exhibit a synchronous, ‘three-stage’ stepwise change over the multi-millennial scale of the Holocene. These stages are roughly marked by the climate events of 8.2 ka and 4.2 ka, with the maximum warm-season temperature and lake water level occurring during the middle Holocene. We find that the maximum rainfall and heat during the middle Holocene in this region roughly coincide with the peak of warm-season (summer-autumn) insolation. This may be related to the significant thermal difference between land and ocean at that time, suggesting a synchronous change in rainfall and temperature in Indian Monsoon domain over long timescales.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"356 ","pages":"Article 109316"},"PeriodicalIF":3.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glaciomarine sediments preserved on the continental margin provide a detailed record of these events. We integrate high-resolution airgun seismic (vertical resolution 5 m), and deep-towed transducer seismic data (vertical and horizontal resolutions 1 and 3 m, respectively) along with age constraints derived from a piston core to determine the seismic stratigraphic framework, depositional architecture, and sedimentation processes of the interfan area between the Kongsfjorden and Isfjorden Trough Mouth Fans (TMFs).

These glacial units on the upper continental slope contain debris materials transported by slow-moving ice sheets. During maximum glacial expansion, iceberg calving created V-shaped indentations, and glaciogenic debris flows carved erosional troughs.

Thus, 112 plant fossil sites from Europe and the Near East were compiled in this study, and qualitative and quantitative biome reconstructions were performed for MIS 6 and MIS 5e. This led to the first pollen based spatial reconstruction of vegetation cover for the penultimate glacial. As expected, vegetation patterns change severely and vegetation density increased with the substantial warming from MIS 6 to MIS 5e. Generally, in MIS 6 central and northern Europe was mainly covered by tundra/mammoth steppe, while temperate grassland, open woodland and shrubland dominated southern Europe. During MIS 5e, Europe was largely forested, with temperate forest in the north and warm forests and shrubland in the south. Still, climatic changes from the penultimate glacial to the last interglacial had regionally different effects on vegetation especially regarding the pace and severity of vegetation overturn. Comparison with published model outputs enables a sound spatial representation of large-scale vegetation patterns on megabiome level. Reducing the granularity of the data of both model and proxy-based biome reconstructions to megabiome level leads to a high level of agreement. Still, some discrepancies remain especially in the northern and easternmost parts of Europe, which could be due to dating issues. However, an underestimation of high latitude warming by the underlying climate models may also contribute to discrepancies in vegetation models compared to proxy data.
