“…Overall cold and dry climate between 12 500 and 11 500 cal yr BP at Lake Dojran can be attributed to the Younger Dryas, when 6 • C lower temperatures and arid conditions with 50 % less annual precipitation compared to modern conditions are reported from the northern Aegean region (Kotthoff et al, 2008a, the Sea of Marmara (Valsecchi et al, 2012), and from other terrestrial records in Italy (Allen et al, 2002), Macedonia (Bordon et al, 2009;, and Greece (Digerfeldt et al, 2000;Lawson et al, 2004). However, the cold and dry climate during the Younger Dryas is barely visible in geochemical and hydrological data from lakes Prespa and Ohrid (Fig.…”

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

“…Palaeoenvironmental reconstructions (e.g. Webb et al 1987;1993a;1993b;Allen et al 1995;Watts et al 1996a;1996b;Bartlein et al 1998;Webb et al 1998;Allen et al 2000Allen et al , 2002Kerwin et al 2004) are made by 'stacking' modern surfaces to produce synthetic modern assemblages for a series of grid nodes, usually 20 x 20 nodes in modern climate space. These synthetic assemblages are then compared to fossil assemblages using a dissimilarity measure, usually the squared chord distance as in MAT.…”

Abstract:The importance of reconstructing past environments quantitatively in palaeoecology is reviewed by showing that many ecological questions asked of palaeoecological data commonly involve the reconstructions of past environment. Three basic approaches to reconstructing past climate from palaeoecological data are outlined and discussed in terms of their assumptions, strengths, and weaknesses. These approaches are the indicator-species approach involving bioclimateenvelope modelling; the assemblage approach involving modern analogue techniques and response surfaces; and the multivariate calibration-function approach. Topics common to all approaches are reviewed -presentation and interpretation, evaluation and validation, comparison, and general limitations of climate reconstructions. Challenges and possible future developments are presented and the potential future role of quantitative climate reconstructions in palaeoecology is summarised.

“…As documented by numerous paleoclimate studies, the Mediterranean region has experienced large scale climate fluctuations over the last glacial-interglacial cycle (Allen et al, 1999(Allen et al, , 2002Bar-Matthews et al, 1999Tzedakis et al, 2003;Martrat et al, 2004;Drysdale et al, 2005;Zanchetta et al, 2008;Vogel et al, 2010a). While information on past temperature variability at relatively high spatial resolution has become available during the past decade (Peyron et al, 1998;Allen et al, 1999;Martrat et al, 2004;Hayes et al, 2005;Marino et al, 2009), information on hydrological changes in the northern Mediterranean borderland is relatively sparse over long time scales (Tzedakis et al, 2003;.…”

Stratigraphic analysis of lake level fluctuations in Lake Ohrid: an integration of high resolution hydro-acoustic data and sediment cores

et al. 2010

Abstract. Ancient Lake Ohrid is a steep-sided, oligotrophic, karst lake that was tectonically formed most likely within the Pliocene and often referred to as a hotspot of endemic biodiversity. This study aims on tracing significant lake level fluctuations at Lake Ohrid using high-resolution acoustic data in combination with lithological, geochemical, and chronological information from two sediment cores recovered from sub-aquatic terrace levels at ca. 32 and 60 m water depth. According to our data, significant lake level fluctuations with prominent lowstands of ca. 60 and 35 m below the present water level occurred during Marine Isotope Stage (MIS) 6 and MIS 5, respectively. The effect of these lowstands on biodiversity in most coastal parts of the lake is negligible, due to only small changes in lake surface area, coastline, and habitat. In contrast, biodiversity in shallower areas was more severely affected due to disconnection of today sublacustrine springs from the main water body. Multichannel seismic data from deeper parts of the lake clearly image several clinoform structures stacked on top of each other. These stacked clinoforms indicate significantly lower lake levels prior to MIS 6 and a stepwise rise of water level with intermittent stillstands since its existence as water-filled body, which might have caused enhanced expansion of endemic species within Lake Ohrid.
