The Neolithic period in Europe was subject to marked climatic variations during the fourth millennium BCE in the Alpine arc, marking the transition between the recent Atlantic and the Subboreal. This ...phase is characterized by falling temperatures and rising humidity in the Northern Hemisphere. Within this phase, between 3700 and 3250 BCE, a more intense phase takes place, known as Rootmoos 2 or Piora 2. This phase is characterized by a significant drop in lake water levels. This climatic change had repercussions on lakeside dwellers, notably through the modification and adaptation of their diet and subsistence modes. Intestinal parasites (helminths), found by human and animals via parasitic markers, seem to respond over time to these climatic variations. At first sight, low lake level phases are characterized by significant proportions of Trichuris at the expense of Diphyllobothrium, as well as an increase in Fasciola. These phases therefore seem to favour parasites indicative of agropastoral activities. During periods of high lake levels, Diphyllobothrium increase in number, pointing to a higher frequency of fishing practices. In sum, during periods of cooler/wetter climate, Neolithic lakeside populations seem to focus more on fishing produce, which may be a response to a destabilization of previously established agropastoral systems, marking a return to more opportunistic behaviour with the exploitation of products from the direct environment. This pilot study tends to evaluate if the evolution of parasitic communities in the 4th millennium BCE could therefore be used to complete our understanding of the effects of climatic variations on societies, both as a direct consequence of environmental destabilization (effect on the hosts) and the result of the behavioural adaptation of the inhabitants, even if it is still difficult to determine the importance of the influence of each factor on these variations. Despite some remaining challenges in the current study, the integration of paleoparasitic data into broader paleoenvironmental models appears promising. Future research can continue to develop along this path.

The archaeobotanical research of the Stare Gmajne pile-dwelling site included analyses of samples taken from moss remains and vessel contents, as well as wood anatomical analyses of several wooden ...artefacts and charcoal pieces.The moss of two forest species and other macroremains provide evidences of human diet and gathering as well as surrounding vegetation in the Eneolithic (3521−3366 cal BC). The results show the inhabitants collected wild plants and cultivated crops, with six cultivars identified. For the wooden artefacts, they show the bow was made of yew and the rings of hazel. They also reveal significant differences between the two excavated trenches and between different stratigraphic units. Further research of the systematically sampled sediments will address questions concerning the possibility of detecting changes in water levels and the location of the Eneolithic settlement. What is already clear is that the organic remains in the present-day Ljubljansko barje soil are highly endangered.
•Radiocarbon date of wooden stilts from 11 villages suggest phases of construction from ∼1st to 13th centuries A.D. (1912 ± 82 to 816 ± 88 calibrated years BP).•A radiocarbon date from one site ...suggests a much earlier habitation in the 4th millenium B.C (6622 ± 119 calibrated years BP).•The Formoso site has dates spanning the longest duration, ∼417 years (255–579 years).•Ceramic sherds and artifacts at Formoso suggest ceremonial activity and possibly foreign cultural influence.•The Formoso site has an uncommon village layout, possibly meant to resemble the Pleiades.
Archaeological surveys conducted in the Maranhão estuaries of Brazil, near the Atlantic coast, revealed the remnants of 21 prehistoric stilt villages constructed on piles of Tabebuia handroanthrus hardwood above three seasonal flood water estuaries. Radiocarbon dates of 27 samples from 11 of those sites yielded an Archaic Period of construction (6622 ± 119 calibrated years before present) followed much later by consecutive construction periods from approximately the first century B.C. to the thirteenth century A.D. (1994 to 728 cal. yrs BP). The Formoso site—currently dated as the longest occupied site (1509 to 930 cal. yrs BP)—yielded early Incised-Punctate/Arauquinoid pottery, a previously unreported pottery style in the Amazon region. Additionally, using StarryNight astronomy software, the night sky at Formoso was compared with a map of the pile dwelling layout, revealing a statistically significant resemblance to the Pleiades. This paper focuses on the Formoso site, suggesting that it may have served cultural significance to the Pleiades as early evidence for the later widespread ethnographic use of the star cluster’s annual sighting to mark the seasonal flood cycles and the management of agricultural and ecological activities throughout tropical South America.
In this paper we estimate the degree to which the range and proportion of wild plant foods are under-represented in samples of charred botanical remains from archaeological sites. We systematically ...compare the differences between central European Neolithic archaeobotanical assemblages that have been preserved by charring compared to those preserved by waterlogging. Charred archaeobotanical assemblages possess on aggregate about 35% of the range of edible plants documented in waterlogged samples from wetland settlements. We control for the ecological availability of wetland versus terrestrial wild plant foods on assemblage composition and diversity, and demonstrate that the significantly broader range of wild plant food taxa represented is primarily a function of preservation rather than subsistence practices. We then consider whether observed fluctuations in the frequency of edible wild taxa over time can also be attributed to preservation, and demonstrate that it cannot; and thus conclude that there are significant changes in plant food diets during the Neolithic that reflect different strategies of land use and, over time, a decreasing reliance on foraging for wild plant foods. The wild species included in our analyses are not spatially restricted—they are common throughout central Europe. We maintain, therefore, that our results are relevant beyond our study area and more generally illustrate the challenges of attempting to reconstruct the relative importance of wild plant foods—and thus plant diet breadth—in Neolithic archaeobotanical assemblages from charred data alone.
•We compare differences between charred and waterlogged samples at European Neolithic sites.•The broader range of wild plant food taxa represented in waterlogged samples is due to preservation.•Diachronic changes in edible wild taxa in the Neolithic reflect different strategies of land use.•Neolithic plant diet breadth cannot be reconstructed from waterlogged samples alone.
On the prehistoric site of Ploča Mičov Grad (Ohrid, North Macedonia) on the eastern shore of Lake Ohrid a total of 799 wooden elements were recorded from a systematically excavated area of nearly 100 ...square metres. Most of them are pile remains made of round wood with diameters up to almost 40 cm. A comprehensive dendrochronological analysis allows the construction of numerous well-replicated tree-ring chronologies for different species. High agreements between the chronologies prove that oak, pine, juniper, ash and hop-hornbeam can be crossdated. The chronologies are dated by means of radiocarbon dates and modelling using wiggle matching. An intensive settlement phase is attested for the middle of the 5th millennium BCE. Further phases follow towards the end of the 5th millennium BCE and in the 2nd millennium around 1800, 1400 and 1300 BCE. Furthermore, the exact, relative felling dates allow first insights into the minimum duration of the settlement phases, which lie between 17 and 87 years. The multi-centennial chronologies presented in this study can be used as a first robust dating basis for future research in the numerous not yet dated prehistoric lake shore settlements of the region with excellently preserved wooden remains.
Across the prehistoric period in Mainland Southeast Asia (MSEA), very few architectural remains and settlements have been identified and there is an absence of evidence for dwellings and domestic ...spaces. Loc Giang (3980–3270 cal BP) in Long An Province, southern Vietnam is one of the few prehistoric settlements excavated in the region, revealing compacted, laterally extensive layers hypothesised to be floors in association with several other occupation deposit types. Due to the complex occupation stratigraphy encountered in the field, as well as intensive post-depositional processes of tropical environments, a state-of-the-art micro-geoarchaeological approach was used to identify site formation processes. Here, we present a description and depositional history of eight major deposit types (microfacies); among these, we identify constructed lime mortar floors, pile dwellings, evidence for the systematic treatment of waste, and prepared organic deposits likely associated with the management of dog and pig populations. Through the study of site formation we reconstruct at high resolution the nature of dwellings and organisation of domestic spaces within one of the earliest neolithic and sedentary settlements in the region. We demonstrate that within destructive burial environments of the tropics, micro-geoarchaeology offers an effective scientific toolkit for detecting settlement features with low macro-archaeological visibility, thereby enabling us to reconstruct pile dwellings and associated lime floors that were poorly characterised previously in MSEA prehistory.

•The prehistoric site of Ploča Mičov Grad shows outstanding preservation conditions.•The analyzed wood provides well replicated dendrochronological mean curves.•Several construction phases of ...Neolithic and Bronze Age settlements are evidenced.
Specialized and systematic underwater fieldwork at the prehistoric site of Ploča Mičov Grad at Gradište (North Macedonia) on the eastern shore of Lake Ohrid was undertaken in 2018 and 2019. It has substantiated the archeological site’s outstanding preservation condition, and furthermore proven the numerous construction timbers’ suitability for dendrochronological analysis. Dendrochronological analysis on archaeological timbers was applied, combined with radiocarbon dating. Bayesian radiocarbon modeling allowed to ‘wiggle match’ the dendrochronological mean curves, i.e. allowed the precise chronological anchoring of ‘floating’ tree-ring sequences. Furthermore, radiocarbon dates of plant remains from the site’s main archaeological layer are statistically evaluated.
Based on the new findings, the strikingly high density of wooden piles at the site can be attributed to several construction phases of Neolithic (middle of 5th millennium BC) and Bronze Age (2nd millennium BC: 1800, 1400 and 1300 BCE) settlements. Intense settlement activity is furthermore evidenced by a cultural layer of mainly organic material under the lakebed up to 1.7 m in thickness, which accumulated during the Neolithic occupation of the bay in the middle of the 5th millennium BC. The presented research enables precise absolute dating of a series of settlement phases at Ploča Mičov Grad from the Neolithic and the Bronze Age, and hence provides important reference points for an absolute chronological framework for the prehistory of the southwestern Balkans. The investigations underline the potential of future research on waterlogged prehistoric settlements in the region.
This study presents the results of an ornitho‐archaeological analysis of avian bones from Stare gmajne and Blatna Brezovica, two Eneolithic pile dwelling sites in the area of Ljubljansko barje, ...Slovenia. Avian bone remains, together with remnants of huts, tools, mammal bones and bones of other vertebrates, represent the material remnant of a pile dwelling culture from the second half of the fourth millennium BC.
A total of 2091 avian bones or fragments thereof were excavated. The avifauna includes 682 taxonomically identified remains (NISP), assigned to 15 bird taxa. Taxonomically, species from the Anatidae group predominate (68.7% of NISP), mainly Bucephala clangula (40.3% of NISP). Also abundant is Fulica atra (26.2% NISP) from the family Rallidae. In the ecological context, species inhabiting aquatic or marshy habitats prevail. Representatives of three ecomorphological groups of waterbirds were found: diving birds (Podiceps sp., Phalacrocorax carbo, Aythya fuligula, B. clangula and Mergus sp.), waterbirds (Cygnus sp., Anser sp., Anas sp. and F. atra) and the marsh species group (Ardea cinerea).
The absence of medullary bone and the abundance of wintering species in the area are consistent with the hypothesis that the birds were captured during the winter season. Taphonomic evidence (burned bones) suggests that the studied assemblages were human food waste. The abundance of avian bone remains supports the hypothesis that the native peoples were skilled hunters of aquatic birds.

A multi-proxy record derived from sediments collected from an infilled lake basin within the area of the Serteya II site, Western Russia, was used to reconstruct the palaeoenvironment development of this site over the past ca. 9000 years. Despite there being archaeological evidence of a human presence in this area spanning several millennia, the results from pollen analysis indicate only a small-scale human impact on vegetation during the prehistory, reinforcing existing ideas that lifeways based upon hunting, fishing and gathering (h-f-g) were maintained over an extended period of time at this location. Human activities remained relatively extensive during the historical periods, although the first evidence of cereal cultivation dates to the Middle Ages. The results of earlier investigation, which suggested that cereal cultivation and animal husbandry may have begun at Serteya in the Late Neolithic, have not been confirmed by the presented dataset (or, at least, cannot be seen in it). The results from macrobotanical analysis reveal a gradual lowering of the lake-level, but with intervening transgression phases ca. 5550–3600 cal. BC and, more briefly, around the time of the 4.2 ka BP cooling event. The Late Neolithic pile dwelling settlement (dated to 2500–2200 cal. BC) that was present in the immediate area, and from which the samples are drawn, was situated in shallow water - the depth of which varied seasonally - and in the close vicinity of the shoreline. The gathering of berries and nuts, as well as starch-rich aquatic plants, seems to have played an important role in subsistence, which was further supported by hunting and fishing. Following a brief phase during which the pile dwelling settlement went into decline, the increased exploitation of aquatic plants appears to have intensified between ca. 2200 and 2000 cal. BC.
