Historical archives from the Roman Monarchic and Republican periods show human perceptions of environment and climate change in Italy, 753–29 BCE
Historical archives for the Roman Monarchic and Republican periods (753–29 BCE) offer a highly resolved series of observations of environmental and climatic phenomena in Central Italy. This paper presents a new collection of these historical archives, gathering 319 observations across the period. We introduce the historical character of these archives and point out aspects affecting their analysis and interpretation for reconstruction of past env…
Lead legacy of pre-industrial activities in lake sediments
A novel, continuous high-resolution palaeoecological record from central Italy suggests comparable land-use dynamics in Southern and Central Europe during the Neolithic
Although rare, temporally and taxonomically highly-resolved palaeoecological studies with high chronological precision are essential to perform detailed comparisons with precisely dated independent evidence such as archaeological findings, historical events, or palaeoclimatic data. Using a new highly-resolved and chronologically precise sedimentary record from Lago di Mezzano (central Italy), we reconstruct decadal-scale vegetation, species diver…
An Environmental and Climate History of the Roman Expansion in Italy
A first synthesis of available data for the period of Rome's expansion in Italy (about 400-29 b.c.e.) shows the role of climate and environment in early Roman imperialism. Although global indices suggest a warmer phase with relatively few short-term climate events occuring around the same time as the expansion, local data emphasize the highly variable timing and expression of these trends. This variability casts doubt on ideas of a unitary, histo…
Geomorphology of the topmost part of the Bistra Mountain, Mavrovo Park, North Macedonia
Identification of the remnant traces of paleo-glaciers provides important proxies to understand the response of the environment to rapid climate changes. We present a 1:25,000 scale geomorphological map covering ∼12.5 km 2 of the upper part of Mount Bistra (North Macedonia) on the basis of remote sensing analyses and geomorphological surveys. Particular attention is given to the description of glacial and periglacial landforms, to the reconstruct…
Geomorphology of the Jebel Qara and coastal plain of Salalah (Dhofar, southern Sultanate of Oman)
We present the results of the geomorphological mapping of a region of the Dhofar (Sultanate of Oman) including two contrasting physiographic units sharing a common drainage system into the Arabian Sea: the Jebel Qara limestone massif and the coastal plain of Salalah. Neogene to Quaternary tectonic activity controlled the formation of an extensive system of faults and caused the uplift of the Jebel Qara, forming structural escarpments. The massif …
The 4.2 ka BP Event in the Mediterranean region
The Mediterranean region and the Levant have returned some of the clearest evidence of a climatically dry period occurring around 4200 years ago. However, some regional evidence is controversial and contradictory, and issues remain regarding timing, progression, and regional articulation of this event. In this paper, we review the evidence from selected proxies (sea-surface temperature, precipitation, and temperature reconstructed from pollen, δ1…
Tephrostratigraphy of paleoclimatic archives in central Mediterranean during the Bronze Age
Evidence for a Younger Dryas deglaciation in the Galicica Mountains (Fyrom) from cosmogenic 36Cl
Geomorphology of the Ceyhan River lower plain (Adana Region, Turkey)
We present a geomorphological map (Main Map) of the lower plain of the Ceyhan River (Adana province, Turkey). Data from three field campaigns and remote sensing observations were managed in a GIS to produce a 1:25,000 scale map. The area, mostly formed by alluvial sediments, is characterized by intense fluvial dynamics with superimposed agricultural activity. Erosional processes prevail on rocky ridges partially bordering the plain on the north-e…
Mid-Holocene relative sea-level changes along Atlantic Patagonia
This paper concerns the relative sea-level changes associated with the Atlantic Patagonian coast derived from sea-level index points whose elevation was determined by a differential global position system (DGPS). Bioencrustations from outcrops located near Camarones, Chubut, Argentina, consist of autochthonous deposits characterized by Austromegabalanus psittacus (Molina, 1782), encrusting acervulinid foraminifera, coralline red algae and bryozoa…
GPR versus Geoarchaeological Findings in a Complex Archaeological Site (Badia Pozzeveri, Italy)
The results of a Ground‐penetrating radar (GPR) survey were compared with the archaeological excavation outcomes of a twelfth century abbey site (Badia Pozzeveri). The goal was to associate the types of reflections recorded in GPR profiles and high‐amplitude features visible in amplitude maps with unearthed archaeological features. GPR profiles crossing the walls evidenced axes of hyperbolic point source reflections and short planar reflections r…
A potential global boundary stratotype section and point (GSSP) for the Tarentian Stage, Upper Pleistocene, from the Taranto area (Italy)
Early–Middle Holocene environmental changes and pre-Neolithic human occupations as recorded in the cavities of Jebel Qara (Dhofar, southern Sultanate of Oman)
A continuous stable isotope record from the penultimate glacial maximum to the Last Interglacial (159–121 ka) from Tana Che Urla Cave (Apuan Alps, central Italy)
Relatively few radiometrically dated records are available for the central Mediterranean spanning the marine oxygen isotope stage 6–5 (MIS 6–5) transition and the first part of the Last Interglacial. Two flowstone cores from Tana che Urla Cave (TCU, central Italy), constrained by 19 U/Th ages, preserve an interval of continuous speleothem deposition between ca. 159 and 121 ka. A multiproxy record (δ 18 O, δ 13 C, growth rate and petrographic chan…
Vegetation, climate and environmental history of the last 4500 years at lake Shkodra (Albania/Montenegro)
Three parallel overlapping cores have been taken in the Albanian side of Lake Shkodra (Albania/Montenegro). The chronological frame of the record, spanning approximately the last 4500 years, has been assessed using four radiocarbon dates and four well-known tephra layers of Italian volcanoes. Multidisciplinary analyses turned out to be decisive to understand environmental, climatic changes and human impact. Here, we focus on palynology. The humid…
Middle- to late-Holocene relative sea-level changes at Puerto Deseado (Patagonia, Argentina)
Stratigraphic, morphologic and radiocarbon data from Puerto Deseado coastal area (Santa Cruz Province, Argentina) indicate that the Holocene coastline formed in response to the discontinuous aggradation of coarse gravely beaches since c. 6300 cal. yr BP related to a progressive falling of relative sea level. Beach ridge crests crudely approximate to the sea level showing at least three steps of aggradation and relative sea-level lowering. Two ina…
Deciphering late Quaternary land snail shell δ 18 O and δ 13 C from Franchthi Cave (Argolid, Greece)
This paper investigates the stable isotopic composition from late Pleistocene–Holocene (~ 13 to ~ 10.5 cal ka BP) shells of the land snail Helix figulina , from Franchthi Cave (Greece). It explores the palaeoclimatic and palaeoenvironmental implications of the isotope palaeoecology of archaeological shells at the time of human occupation of the cave. Modern shells from around the cave were also analysed and their isotopic signatures compared with…
North–south palaeohydrological contrasts in the central Mediterranean during the Holocene
On the basis of a multi-proxy approach and a strategy combining lacustrine and marine records along a north–south transect, data collected in the central Mediterranean within the framework of a collaborative project have led to reconstruction of high-resolution and well-dated palaeohydrological records and to assessment of their spatial and temporal coherency. Contrasting patterns of palaeohydrological changes have been evidenced in the central M…
A map for volcaniclastic debris flow hazards in Apennine areas surrounding the Vesuvius volcano (Italy)
Volcaniclastic debris flows are dangerous natural phenomena that originate in volcanic areas not only during or shortly after an eruption but also during a period of volcanic quiescence, when heavy and/or persistent rains remobilize unconsolidated pyroclastic deposits.In Italy, one of the areas most affected by these phenomena is that of the Apennine Mountains which border the southern Campania Plain surrounding the Vesuvius volcano.Historical ac…
Climatic interpretation of carbon isotope content of mid-Holocene archaeological charcoals from eastern Anatolia
Stable carbon isotope analysis as a crop management indicator at Arslantepe (Malatya, Turkey) during the Late Chalcolithic and Early Bronze Age
Constraining the onset of the Holocene “Neoglacial” over the central Italy using tephra layers
A study of six tephra layers discovered in different deposits between 1600 and 2700 m a.s.l. in the Apennine chain in central Italy allowed precise stratigraphic constraints on environmental and climatic changes between ca. 4.5 and 3.8 cal ka BP. Chemical analyses allowed the correlation of these tephra layers with the eruptions of Agnano Mt Spina (AMST) from Phlegrean Field and Avellino (AVT) from Somma–Vesuvius. Major environmental changes in t…

Possible complexity of the climatic event around 4300—3800 cal. BP in the central and western Mediterranean
This paper presents an event stratigraphy based on data documenting lake-level changes as well as volcanic eruptions over the period 4500—3500 cal. BP from sediment sequences of Lakes Accesa in Tuscany (north-central Italy) and Maliq (Albania) in the central Mediterranean. The available data make it possible to recognise a tripartite climatic oscillation between c. 4300—3800 cal. BP. A phase characterised by drier conditions at c. 4100—3950 cal. …
Tephrostratigraphy, chronology and climatic events of the Mediterranean basin during the Holocene
The identification and characterisation of high-frequency climatic changes during the Holocene requires natural archives with precise and accurate chronological control, which is usually difficult to achieve using only 14 C chronologies. The presence of time-spaced tephra beds in Quaternary Mediterranean successions represents an additional, independent tool for dating and correlating different sedimentary archives. These tephra layers are potent…

Mollusca stable isotope record of a core from Lake Frassino, northern Italy
A core retrieved from Lake Frassino (northern Italy) provided evidence of palaeohydrological change in this area during the last 14 ka. Lithological, malacological and, in particular, stable isotope composition of freshwater shells allowed the delineation of the main phases of lake evolution between the Lateglacial and Holocene. Lateglacial conditions were drier than the Holocene, although a wetter period was inferred before c. 14 ka. According t…

C-dating from an old quarry waste dump of Carrara marble (Italy)
A 37-Meter Record of Paleoclimatological Events from Stable Isotope Data on Continental Molluscs in Valle di Castiglione, Near Rome, Italy
New stable isotope analyses on molluscan shells from a long core drilled in the crater lake of Valle di Castiglione, near Rome, extended the investigated portion of the core to 37 m. The succession of δ 18 O‰ values in the core interval 37–2.3 m ranges from −2.8 to +6.9‰ with only six samples below 0‰ (PDB) . These results point to arid climatic phases coupled with the high measured δ 18 O values of the biogenic carbonate. In contrast, depleted 1…
C-dating from an old quarry waste dump of Carrara marble (Italy)
Late Holocene drought responsible for the collapse of Old World civilizations is recorded in an Italian cave flowstone
A severe drought in parts of low-latitude northeastern Africa and southwestern Asia\n\nca 4200 yr ago caused major disruption to ancient civilizations. Stable isotope, trace element,\n\nand organic fluorescence data from a calcite flowstone collected from the wellwatered\n\nAlpi Apuane karst of central-western Italy indicate that the climatic event responsible\n\nfor this drought was also recorded in mid-latitude Europe. Although the timing\n\nof…

This paper presents an event stratigraphy based on data documenting lake-level changes as well as volcanic eruptions over the period 4500—3500 cal. BP from sediment sequences of Lakes Accesa in Tuscany (north-central Italy) and Maliq (Albania) in the central Mediterranean. The available data make it possible to recognise a tripartite climatic oscillation between c. 4300—3800 cal. BP. A phase characterised by drier conditions at c. 4100—3950 cal. …
The Holocene climatic evolution of Mediterranean Italy
We present a synthesis of geological, stratigraphic, geomorphological and stable isotope data collected from continental archives to highlight the environmental and climatic differences between the first and second half of the Holocene of central and southern Italy. The beginning of the Holocene is marked by rapid environmental change. In Mediterranean Italy, between c. 9500 cal. BP and c. 6000—5500 cal. BP, average temperatures were probably hig…
Insights into the Holocene environmental setting of Terra Nova Bay region (Ross Sea, Antarctica) from oxygen isotope geochemistry of Adélie penguin eggshells
An oxygen isotope record of Adélie penguin ( Pygoscelis adeliae) eggshells from Terra Nova Bay (Victoria Land, Antarctica) has been reconstructed in order to provide insights into the palaeoenviroment of this region during the last ~8000 years. The δ 18 O values measured in eggshell carbonate show a great variability over the course of the studied period, with maximum values consistently around +27.5‰. Adopting a metabolic enrichment relative to …
