New tree-ring evidence for the Late Glacial period from the northern pre-Alps in eastern Switzerland
2018
Abstract The rate and magnitude of temperature variability at the transition from the Last Glacial Maximum into the early Holocene represents a natural analog to current and predicted climate change. A limited number of high-resolution proxy archives, however, challenges our understanding of environmental conditions during this period. Here, we present combined dendrochronological and radiocarbon evidence from 253 newly discovered subfossil pine stumps from Zurich, Switzerland. The individual trees reveal ages of 41–506 years and were growing between the Allerod and Preboreal (∼13′900–11′300 cal BP). Together with previously collected pines from this region, this world's best preserved Late…
Late Upper Palaeolithic hunter-gatherers in the Central Mediterranean: New archaeological and genetic data from the Late Epigravettian burial Oriente…
2019
AbstractGrotta d’Oriente, a small coastal cave located on the island of Favignana (Sicily, Italy) is a key site for the study of the early human colonization of Sicily. The individual known as Oriente C was found in the lower portion of an anthropogenic deposit containing typical local Late Upper Palaeolithic (Late Epigravettian) stone assemblages. Two radiocarbon dates on charcoal from the deposit containing the burial are consistent with the archaeological context and refer Oriente C to a period spanning about 14,200-13,800 cal. BP. Anatomical features are close to those of Late Upper Palaeolithic populations of the Mediterranean and show strong affinity with Palaeolithic individuals of S…
Late Weichselian and Holocene record of the paleoenvironmental changes in a small river valley in Central Poland
2016
Abstract: The developmental history, from the Oldest Dryas to the Late Holocene, of a paleolake and mire located in a river valley in Central Poland was studied using high-resolution records of pollen, macrofossils, Cladocera, sedimentology, and geochemistry from a 14 C dated sediment core. We inferred temperature and water level dynamics using cladocerans and palynological and geochemical methods were employed to investigate natural fluvial activity, particularly for these elements that are difficult to find through sedimentological methods. Our research demonstrates how climate fluctuation in the Late Glacial and Holocene periods influenced the development of a paleolake and mire in a sma…
Illuminating Intcal During the Younger Dryas
2020
As the worldwide standard for radiocarbon (14C) dating over the past ca. 50,000 years, the International Calibration Curve (IntCal) is continuously improving towards higher resolution and replication. Tree-ring-based 14C measurements provide absolute dating throughout most of the Holocene, although high-precision data are limited for the Younger Dryas interval and farther back in time. Here, we describe the dendrochronological characteristics of 1448 new 14C dates, between ~11,950 and 13,160 cal BP, from 13 pines that were growing in Switzerland. Significantly enhancing the ongoing IntCal update (IntCal20), this Late Glacial (LG) compilation contains more annually precise 14C dates than any…
The response of a shallow lake and its catchment to Late Glacial climate changes — A case study from eastern Poland
2015
In this study we investigate how climate fluctuation in the Late Glacial period influenced the development of a lake and its catchment located in the East European Plain. We analyzed the sediments of the lake for pollen, subfossil Cladocera, macrofossils and chemical composition. We aimed at disentangling: (1) the climate changes and their limno-ecological responses, (2) temperature dynamics with the use of Cladocera-based transfer function (MJT) and macrofossil-based reconstruction of mean minimum July temperature (MMJT), (3) timing of the response of different proxies to environmental changes. The results of multiproxy analyses explicitly suggest that the main driver for changes in aquati…
Relations entre sociétés et environnement en Petite Seine du Mésolithique à la fin du Moyen Âge : nouvelles problématiques et résultats récents d’arc…
2021
Actes du colloque Arkéaube; International audience; This jointly authored paper encompasses several contributions which highlight new issues in environmental archaeology and incorporate palaeo-environmental data from preventiveexcavations. More specifically, it broaches three questions:-The evolution of the environment from the Late Glacial to the present day is analysed using faunal remains (malacofaunae—molluscs, etc.) and botanicalremains (pine trunks) preserved in the alluvial deposits of the river Seine;-Riverside occupations based on reconstructions of the hydrography and hydrographic functioning of the channels documented in the Pont-sur-Seine sector and in Bassée;-The marshes assume…
Arheoloģija Baltijā 21. gs. sākumā: jaunākie pētījumi, aktuālās diskusijas un mūsdienu izaicinājumi: referātu kopsavilkumi, 2022. gada 18. februārī L…

Jau divas desmitgades Latvijas Universitātes (LU) starptautiskās zinātniskās konferences ietvaros katru otro gadu norisinās Arheoloģijas sekcija, ko rīko LU Vēstures un filozofijas fakultāte. Pirmoreiz šāda sekcija tika rīkota LU 61. zinātniskajā konferencē 2003. gada 10. februārī. Turpinot iesākto tradīciju, arī 2022. gada 18. februārī LU 80. starptautiskās konferences ietvaros Vēstures un filozofijas fakultātes Vēstures un arheoloģijas nodaļa organizēja arheoloģijas problemātikai veltītu sekciju, kurā tika aplūkotas daudzveidīgās un aktuālās mūsdienu arheoloģijas attīstības tendences Latvijā un Eiropā. Daļa konferences referātu pievērsās dabaszinātņu un tās pētniecisko metožu lomai arheol…
