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 influenced by river discharge, and site Co1202 which is close to the steep eastern slopes. Variable proportions of terrestrial n-alkanoic acids and n-alkanols as well as compositional changes of !- hydroxy acids document differences in soil organic matter supply between the sites and during different climate stages (glacial, Holocene, 8.2 ka cooling event). Changes in the vegetation cover are suggested by changes in the dominant chain length of terrestrial n-alkanols. Effective microbial degradation of labile organic matter and in situ contribution of organic matter derived from the microbes themselves are both evident in the sediments. We found evidence for anoxic conditions within the photic zone by detecting epicholestanol and tetrahymanol from sulphur-oxidising phototrophic bacteria and bacterivorous ciliates and for the influence of a settled human community from the occurrence of coprostanol, a biomarker for human and animal faeces (pigs, sheep, goats), in an early Holocene sample. This study illustrates the potential of lipid biomarkers for future environmental reconstructions using one of Europe’s oldest continental climate archives, Lake Ohrid.

Correlating the Ancient Maya and Modern European Calendars with High-Precision AMS 14C Dating

The reasons for the development and collapse of Maya civilization remain controversial and historical events carved on stone monuments throughout this region provide a remarkable source of data about the rise and fall of these complex polities. Use of these records depends on correlating the Maya and European calendars so that they can be compared with climate and environmental datasets. Correlation constants can vary up to 1000 years and remain controversial. We report a series of high-resolution AMS C-14 dates on a wooden lintel collected from the Classic Period city of Tikal bearing Maya calendar dates. The radiocarbon dates were calibrated using a Bayesian statistical model and indicate that the dates were carved on the lintel between AD 658-696. This strongly supports the Goodman-Martinez-Thompson (GMT) correlation and the hypothesis that climate change played an important role in the development and demise of this complex civilization.

Ancient DNA, a Neolithic legging from the Swiss Alps and the early history of goat

Ancient DNA from a Neolithic legging (1st half of the 3rd millennium BC) found at Lenk, Schnidejoch (2750 m a.sl.) in the Swiss Alps has demonstrated, that modern distribution of genetic variation does not reflect past spatio-temporal signatures. The legging was made from the skin of a domestic goat (Capra hircus), belonging to the caprine haplogroup B1, which is marginal in Europe today, but represents a third highly diverse goat haplogroup entering Europe already in the Neolithic. Population expansion of lineage B therefore happened more than 4500 years ago, but their members were at some point almost completely replaced by goats of today's common A and C haplogroups.

Ancient History as a Means of Transforming Colonial India in the Late-Eighteenth and Early-Nineteenth Centuries

This article focuses on the studies and discourses of mostly British scholars of the early colonial period belonging to two schools of thought. It shows how the studies of both schools – European orientalism and utilitarianism – were intricately connected to the political development of the emerging British paramountcy over the South Asian sub-continent, as both were looking for means of establishing and/or strengthening colonial rule. Nevertheless, the debate was not just a continuation of discussions in Europe. Whereas the ideas of the European Enlightenment had some influence, the transformation of the Mughal Empire and especially the idea of a decline of Muslim rule offered ample opportunities for understanding the early history of India either as some sort of “Golden Age,” as the orientalists and their indigenous supporters did, or as something static and degenerate, as the utilitarians did, and from which the population of sub-continent had to be saved by colonial rule and colonial values. Fearing the spread of the ideas of the French Revolution, the first group of British scholars sought to persuade the native elites of South Asia to take the lessons of their past for the future development of their homeland. Just as the classicists back in Europe, these scholars were convinced that large-scale explanations of the past could also teach political and moral lessons for the present although it was important to deal with the distant past in an empirical manner. The utilitarians on the other hand believed that India had to be saved from its own depravity through the English language and Western values, which amounted to nothing less than the modern transformation of the true Classical Age.
