“…2). Relatively arid conditions in the Mediterranean region during the late Holocene are also reported from other records, including Lake Prespa (Schilman et al, 2001;Roberts et al, 2008 and references therein;Joannin et al, 2012;Leng et al, 2012;Siani et al, 2012). A lower lake level at Lake Dojran could have resulted in a relative enlargement of shallow lake areas covered by reed beds.…”

“…6000 and 4300 cal yr BP correlates with a minimum in K and Fe and suggests slightly increased productivity, slightly reduced lake level and lower supply of clastic material. This is likely correlated to warmer temperatures and more arid conditions during the mid-Holocene, such as observed in other paleoclimate records in the Mediterranean region (e.g., Wick et al, 2003;Kotthoff et al, 2008a,b;Roberts et al, 2008;Wagner et al, 2009;Leng et al, 2010;Vogel et al, 2010a;Aufgebauer et al, 2012;Joannin et al, 2012). The shift from more humid to more arid conditions at Lake Dojran was only moderate, as OM, TS, TOC/TS, TOC/TN, δ 13 C org , and δ 18 O carb in core Co1260 are relatively stable between 7900 and 4300 cal yr BP.…”

“…The decreasing δ 18 O carb after 10 200 cal yr BP could be associated with a greater through flow due to further increasing humidity. This corresponds with increasing moisture in southern Italy until 9400 cal yr BP (Joannin et al, 2012), but in particular with increasing δ 18 O carb after 9400 cal yr BP at Lake Prespa, which was explained by increasing summer wetness (Leng et al, 2010). Despite this increasing humidity during the early Holocene, which incidentally coincides partly with the formation of sapropel 1a between ca.…”

A Late Glacial to Holocene sediment sequence (Co1260, 717 cm) from Lake Dojran, located at the boarder of the F.Y.R. of Macedonia and Greece, has been investigated to provide information on climate variability in the Balkan region. A robust age-model was established from 13 radiocarbon ages, and indicates that the base of the sequence was deposited at ca. 12 500 cal yr BP, when the lake-level was low. Variations in sedimentological (H₂O, TOC, CaCO₃, TS, TOC/TN, TOC/TS, grain-size, XRF, δ¹⁸O_carb, δ¹³C_carb, δ¹³C_org) data were linked to hydro-acoustic data and indicate that warmer and more humid climate conditions characterised the remaining period of the Younger Dryas until the beginning of the Holocene. The Holocene exhibits significant environmental variations, including the 8.2 and 4.2 ka cooling events, the Medieval Warm Period and the Little Ice Age. Human induced erosion processes in the catchment of Lake Dojran intensified after 2800 cal yr BP

“…Climate at nearby Fagnano Castello (Cosenza province) has a mean annual temperature of 15 • C, (24 • C for August and 7.5 • C for January). Despite the strictly Mediterranean latitude of the studied area, annual precipitation (including cloudiness) is high (1849 mm yr −1 ), though a relatively short dry period does occur in the summer season (Joannin et al, 2012). Forest surrounding Lake Trifoglietti is dominated by Fagus with some Pinus nigra subsp.…”

Contrasting patterns of climatic changes during the Holocene across the Italian Peninsula reconstructed from pollen data

Lake-level records from Italy suggest that patterns of precipitation in the central Mediterranean during the Holocene were divided between the north and south, but a scarcity of reliable palaeoclimatic records in the north and central-southern Mediterranean means new evidence is needed to validate this hypothesis. We provide robust quantitative estimates of Holocene climate in the Mediterranean region using four high-resolution pollen records from northern (Lakes Ledro and Accesa) and southern (Lakes Trifoglietti and Pergusa) Italy. Multiple methods are used to provide an improved assessment of the palaeoclimatic reconstruction uncertainty. The multi-method approach uses the pollenbased weighted averaging, weighted-average partial leastsquares regression, modern analogue technique, and the nonmetric multidimensional scaling/generalized additive model methods. We use independent lake-level data to validate the precipitation reconstructions. Our results support a climatic partition between northern and southern Italy during the Holocene, confirming the hypothesis of opposing mid-Holocene summer precipitation regimes in the Mediterranean. The northern sites (Ledro, Accesa) are characterized by minima for summer precipitation and lake levels during the early to midHolocene, while the southern sites (Trifoglietti, Pergusa) are marked by maxima for precipitation and lake levels at the same time. Both pollen-inferred precipitation and lake levels indicate the opposite pattern during the late Holocene, a maximum in northern Italy and a minimum in southern Italy/Sicily. Summer temperatures show the same partitioning, with warm conditions in northern Italy and cool conditions in Sicily during the early/mid-Holocene, and a reversal during the late Holocene. Comparison with marine cores from the Aegean Sea suggests that climate trends and gradients observed in Italy show strong similarities with those recognized from the Aegean Sea, and more generally speaking in the eastern Mediterranean

In the context of global decline in old-growth forest, historical ecology is a valuable tool to derive insights into vegetation legacies and dynamics and develop new conservation and restoration strategies. In this cross-disciplinary study, we integrate palynology (Lago del Pesce record), history, dendrochronology, and historical and contemporary land cover maps to assess drivers of vegetation change over the last millennium in a Mediterranean mountain forest (Pollino National Park, southern Italy) and discuss implications in conservation ecology. The study site hosts a remnant beech-fir (Fagus sylvatica-Abies alba) mixed forest, a priority habitat for biodiversity conservation in Europe. In the 10th century, the pollen record showed an open environment that was quickly colonized by silver fir when sociopolitical instabilities reduced anthropogenic pressures in mountain forests. The highest forest cover and biomass was reached between the 14th and the 17th centuries following land abandonment due to recurring plague pandemics. This
