Lipid biomarkers in Holocene and glacial sediments from ancient Lake Ohrid (Macedonia, Albania)

Abstract: Organic matter preserved in Lake Ohrid sediments originates from aquatic and terrestrial sources. Its variable composition reflects climate-controlled changes in the lake basin's hydrology and related organic matter export, i.e. changes in primary productivity, terrestrial plant matter input and soil erosion. Here, we present first results from lipid biomarker investigations of Lake Ohrid sediments from two near-shore settings: site Lz1120 near the southern shore, with low-lying lands nearby and probably … Show more

“…Woody plants are much more resistant to low temperature and humid conditions and are sources for C 27 and C 29 , while herbaceous plants are the main source of C 31 and are more sensitive to cold weather and arid weather. Thus, changes in the composition of terrigenous plants can be associated with changes in climate and hydrology conditions.…”

“…The procedure proposed by Hofmann et al [30] and Holtvoeth et al [31] were followed. Briefly, bulk sediment (5 g) was extracted using an accelerated solvent extractor (ASE; Dionex) in 5-minute static cycles (100°C; 4 MPa) with a mixture of dichloromethane (DCM) and acetone (1:1 v/v).…”

“…Though the shores of Lake Ohrid might have been populated for thousands of years (Holtvoeth et al, 2010), over the past decades three lakeside towns -Ohrid, Struga, and Pogradec -have grown considerably with a combined population approaching 200 000 in 2008 according to the State Statistical Offices of Macedonia and Albania (GeoHive, 2010; Fig. 2a).…”
