Changes in past subsistence strategies reflect the adaptation of human societies to climatic, environmental, and cultural settings. Despite being a resistant, flexible, and nutritive crop, millet only sporadically became a staple crop in Europe and is nearly forgotten today. This raises the question of the cultural dimensions associated with the adoption or rejection of millet. We use a multi-isotope dataset from Bronze Age Poland (2200 to 1000 BCE) coupled with radiocarbon dates to identify dietary practices and associate them with cultural and environmental conditions. We (i) revise the earliest evidence for millet consumption in Europe to 1590 ± 50 calibrated years (cal) BCE instead of 1460 ± 40 cal BCE, (ii) reconstruct dietary shifts at the group and individual level, (iii) suggest environmental instead of cultural mechanisms behind millet adoption, and (iv) reveal land-use shifts associated with millet cultivation, showing no strong evidence for a demic diffusion model. The gained insights into crop integration processes can help in discussing coping strategies for present-day challenges.

Diatoms are regarded as reliable bioindicators for assessing heavy metal contamination in marine ecosystem including mercury. In the present study diatoms were used as bioindicators to reconstruct changes in the concentration of total mercury and its fractions in the Middle and Late-Holocene in the southern Baltic based on a 450 cm long sediment core. The goal of the study was to reconstruct changes in the concentration of Hg _tot and its fractions in relation to biodiversity of the diatom flora, climatic fluctuations occurring inferred from pollen and Pediastrum records and in relative abundance of sediment fractions. Hg _tot concentration increased from 4.6 ng g ⁻¹ (6300 cal. yr BP) to 353 ng g ⁻¹ (2021). Among the analyzed fractions HgS (⩽86.6%) dominated until ca. 4200 cal. yr BP after which a gradual increase in the proportion of Hg _F2 (⩽69.8%), was observed. The current study showed that over the last 6300 cal. yr BP the increase in Hg concentrations in the sediments of the Puck Bay has been influenced by human activities in addition to natural sources (atmospheric input, climatic fluctuations, storm events, diatoms productivity). About 4200–200 cal. yr BP the diatoms Schionodiscus oestrupii and Rhizosolenia hebetata f. hebetata enabled the identification eight time intervals during which climatic fluctuations influenced changes in sedimentary Hg _tot concentrations. Over the last ca. 200 cal. yr BP the highest Hg concentrations were associated with intensive human activity as evidenced by the anthropogenic diatom flora present at that time ( Cyclotella choctawhatcheeana , Thalassiosira levanderi ).

The article reports the results of research focused on Barrow 3 in Ivanivtsi-Antonivka, Vinnitsia oblast, Ukraine, which was carried out by a Polish-Ukrainian team in 2019. This small and badly damaged barrow contained just seven features, including only two graves. The results of the multifaceted analyses indicated that despite the small number of sites, the history of the barrow can be divided into three phases – all resulting from the activity of communities associated with the Chornolis culture. Two phases were related to the placement of graves and the enlargement of the mound: Phase 2 (820–770 BC) and Phase 3 (750–685 BC). In contrast, the earliest Phase 1 (960–930 BC) probably covers the demarcation of the ceremonial/ritual space through the placement of a central post, the digging of a ditch, the rising of a mound (?) and the holding of a ceremonial feast. Remarkably, this stage did not end at all with the placement of a grave in the designated space or at least no traces of this have been found. The two excavated graves were intended for women. In both cases, the deceased were accompanied by a similar set of artefacts: a clay cup and a clay spindle whorl probably representing a spindle. It seems that this recurrent set was meant to stress one of the major tasks of women namely the manufacture of textiles. At present, the barrow discussed here does not find any full analogies, as sites concealing modest female burials associated with the Chornolis culture have not been studied in much detail.

In the face of human land use and climate dynamics, it is essential to know the key drivers of plant species diversity in montane regions. However, the relative roles of climate and ungulates in alpine ecosystem change is an open question. Neither observational data nor traditional palaeoecological data have the power to resolve this issue over decadal to centennial timescales, but sedimentary ancient DNA (sedaDNA) does. Here we record 603 plant taxa, as well as 5 wild, and 6 domesticated mammals from 14 lake sediment records over the last 14,000 years in the European Alps. Sheep were the first domesticated animals detected (at 5.8 ka), with cattle appearing at the early Bronze Age (4.2 ka) and goats arriving later (3.5 ka). While sheep had an impact similar to wild ungulates, cattle have been associated with increased plant diversity over the last 2 ka by promoting the diversity of forbs and graminoids. Modelling of the sedaDNA data revealed a significantly larger effect of cattle and wild ungulates than temperature on plant diversity. Our findings highlight the significant alteration of alpine vegetation and the entire ecosystem in the Alps by wild and domesticated herbivores. This study has immediate implications for the maintenance and management of high plant species diversity in the face of ongoing anthropogenic changes in the land use of montane regions.

We report a set of radiocarbon dating of prehistoric settlements located on the paleolake Baruun Khuree shores in the Gobi-Altai area, southern Mongolia. The obtained series of 11 AMS ¹⁴C measurements on charcoal and other charred plant macro-remains can be associated with one of the earliest episodes of the Holocene highly mobile desert-adapted hunter-gatherers activities from the Gobi desert (ca. 11,250–10,500 cal BP). Exploiting a wide range of environments, including dune fields, they are characterized by pottery usage and microblade core technology with wedge-shaped cores as well as osteological materials. These preliminary results are part of a project analyzing the nature of long-lasting prehistoric occupation around Tsakhiurtyn Hundi (Eng. Flint Valley)—one of the most extensive early prehistoric sites of Central Asia owing its name to the presence of abundant flint outcrops, lithic workshops and their innumerable flint artifacts.

The “princely” barrows of Łęki Małe, Greater Poland are the oldest such monuments within the distribution area of Únětice societies in Central Europe. While in the Circum-Harz group and in Silesia similar rich furnished graves under mounds have appeared as single monuments as early as 1950 BC, Łęki Małe represents a chain of barrows constructed between 2150 BC and 1800 BC. Of the original 14 mounds, only four were preserved well enough that their complex biographies can now be reconstructed. They included ritual activities (before, during, and after the funeral), and also subsequent incursions, including robberies. The long lasting barrow cemetery at Łęki Małe can be linked to a nearby fortified site, Bruszczewo. Together, Łęki Małe and Bruszczewo represent a stable, socially differentiated society that existed for no less than 350–400 years. Therefore, it can be argued that the Early Bronze Age societies of Greater Poland were extremely sustainable in comparison to those of other Únětice regions.
