Article
Full-text available
Understanding Holocene hydroclimatic variability in the European Alps is challenging due to spatial and temporal disparities between the northern and southern Alps. In addition, interpreting lake sediment records in terms of paleohydrology is complicated by human presence during Roman and Medieval settlements, which increased soil erosion and lake...
Article
Taxonomic clarification of Tonnacypris stewarti comb. nov. (= Herpetocypris stewarti), a non-marine ostracod first described by Daday in 1908, was required due to the existence of various synonyms without detailed morphological descriptions. Our study examined specimens from Mang-tsa, Nam Co (Tibetan Plateau) and Lake Band-e Amir (Afghanistan). We...
Presentation
A comprehensive understanding of Holocene hydroclimate variability in the European Alps remains challenging because of the great spatial and temporal disparities between the northern and southern Alps, mainly caused by changes in atmospheric circulation patterns and different climate settings. Most of the hydroclimate studies are based on lake leve...
Presentation
The Himalayan region is a key area for climate and environmental change and has experienced rapid and pronounced changes over the past decades. Paleoenvironmental studies from this region are crucial to understand natural climate variability. Here we investigate a ~150 cm long sediment core, spanning over the last ~7 cal. ka BP, from a small high-a...
Chapter
Full-text available
Ecosystems are continuously responding to both natural and anthropogenic environmental change. Lake sediments preserve local and global evidence of these ecological transitions through time. This archived information can yield crucial insights through the reconstruction of past changes over hundreds to many thousands of years. This chapter provides...
Chapter
Diatoms (Bacillariophyta) are unicellular eukaryotic algae that contribute largely to the primary production of lakes and oceans and play an important role in global carbon, nitrogen and silica cycles. They are abundant and ubiquitous in almost all aquatic environments, they are particularly sensitive to environmental perturbations and are well pre...
Article
Full-text available
Archaeologists do not always differentiate between human activities, practices and techniques within landscape archaeology. This problem is reflected in some research into the development of pastoralism in the Alps. Here, we develop a framework within a “position paper” that engages with these different processes by assessing recent developments in...
Article
Full-text available
Sediments serve as an archive of human and animal activity and environmental conditions through their physical and chemical properties as well as captured biological traces. Archaeologists have been extracting information from archaeological soils and sediments for decades, but recent technological developments, such as the analysis of lipid biomar...
Article
Full-text available
Alpine ecosystems on the Tibetan Plateau are being threatened by ongoing climate warming and intensified human activities. Ecological time-series obtained from sedimentary ancient DNA (sedaDNA) are essential for understanding past ecosystem and biodiversity dynamics on the Tibetan Plateau and their responses to climate change at a high taxonomic re...
Article
Full-text available
The history of the British Isles and Ireland is characterized by multiple periods of major cultural change, including the influential transformation after the end of Roman rule, which precipitated shifts in language, settlement patterns and material culture¹. The extent to which migration from continental Europe mediated these transitions is a matt...
Article
Full-text available
The remarkable archaeological record of Neolithic Orkney has ensured that these islands play a prominent role in narratives of European late prehistory, yet knowledge of the subsequent Bronze Age is comparatively poor. The Bronze Age settlement and cemetery at the Links of Noltland, on the island of Westray, offers new evidence, including aDNA, tha...
Article
Full-text available
Lake sediments represent valuable and widely used archives for tracking environmental and biotic changes over time. Past aquatic communities are traditionally studied via morphological identification of the remains of organisms. However, molecular identification tools, such as DNA metabarcoding, have revolutionized the field of biomonitoring by ena...
Article
Full-text available
Significance The Orcadian Neolithic has been intensively studied and celebrated as a major center of cultural innovation, whereas the Bronze Age is less well known and often regarded as a time of stagnation and insularity. Here, we analyze ancient genomes from the Orcadian Bronze Age in the context of the variation in Neolithic Orkney and Bronze Ag...
Article
Full-text available
Historical records document medieval immigration from North Africa to Iberia to create Islamic al-Andalus. Here, we present a low-coverage genome of an eleventh century CE man buried in an Islamic necropolis in Segorbe, near Valencia, Spain. Uniparental lineages indicate North African ancestry, but at the autosomal level he displays a mosaic of Nor...
Conference Paper
Full-text available
Since the seminal paper in 1998 (Coolen and Overmann), sedimentary ancient DNA (sedaDNA) has become a powerful tool in paleoecology to reconstruct past changes in terrestrial and aquatic biodiversity. Still, sedaDNA is an emerging tool and there is a need for calibrations and validations to ensure the reliability of sedaDNA as a proxy to reconstruc...
Article
Intentional facial disfigurement is documented in archaeological contexts around the world. Here, the authors present the first archaeological evidence for intentional facial mutilation from Anglo-Saxon England—comprising the removal of the nose, upper lip and possible scalping—inflicted upon a young adult female. The injuries are consistent with d...
Article
Full-text available
Large, old and heterogenous lake systems are valuable sources of biodiversity. The analysis of current spatial variability within such lakes increases our understanding of the origin and establishment of biodiversity. The environmental sensitivity and the high taxonomic richness of diatoms make them ideal organisms to investigate intra-lake variabi...
Article
Human remains from the Iron Age in Atlantic Scotland are rare, which makes the assemblage of an adult female and numerous foetal bones at High Pasture Cave, on the Isle of Skye, particularly noteworthy. Archaeological evidence suggests that the female had been deposited as an articulated skeleton when the cave entrance was blocked off, marking the...
Article
Two key moments shaped the extant South Asian gene pool within the last 10 thousand years (ka): the Neolithic period, with the advent of agriculture and the rise of the Harappan/Indus Valley Civilisation; and Late Bronze Age events that witnessed the abrupt fall of the Harappan Civilisation and the arrival of Indo-European speakers. This study focu...
Article
Full-text available
We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula.We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming.We reveal sporadic contacts be...
Article
Full-text available
The Arctic treeline ecotone is characterised by a steep vegetation gradient from arctic tundra to northern taiga forests, which is thought to influence the water chemistry of thermokarst lakes in this region. Environmentally sensitive diatoms respond to such ecological changes in terms of variation in diatom diversity and richness, which so far has...
Article
Full-text available
The increase in atmospheric carbon dioxide (CO2) leads to rising temperatures and acidification in the oceans, which directly or indirectly affects all marine organisms, from bacteria to animals. We here ask whether the simplest—and possibly also the oldest—metazoan animals, the placozoans, are particularly sensitive to ocean warming and acidificat...
