Description: The paper presents the result of analysis of charred food on the interior part of the vessels from the graves of the East Manych and West Manych Catacomb archaeological cultures (2500–2350 cal bc ). The phytolith and pollen analyses identified pollen of wild steppe plants and phytoliths of domesticated gramineous plants determined as barley phytoliths. Direct 14 С dating of one of the samples demonstrates that barley spikelets and stems were used in funeral rites by local steppe communities. However, there are no data suggesting that steppe inhabitants of the Lower Don Region were engaged in agriculture in the mid-3000 bc . Supposedly, barley could have reached the steppes through seasonal migrations of mobile pastoralists to the south, use of North Caucasus grasslands in the economic system of seasonal moves and exchange with local people. Nevertheless, presence of carbonized barley seeds in the occupation layers at North Caucasus settlements of 4000–3000  bc requires confirmation by direct 14 С dating of such samples.

Description: Plant domestication is a complex process in which natural and cultural factors play important roles delimiting evolutionary pathways of plants under cultivation. In order to deal with and understand the changes generated during this process, multi-disciplinary research is required, especially when a full picture of the domestication history of a taxon is to be assessed. We present here some advances in the study of Cucurbita maxima (squash) domestication from an integrated perspective, including experimental, morphometric and archaeobotanical approaches, which are discussed in the light of new data from physiological analyses. Modern material includes plants obtained from experimental fields, derived from crosses between domesticated ( C. maxima ssp. maxima ) and spontaneous/wild forms ( C. maxima ssp. andreana ), resulting in F1 and F2 generations. The archaeobotanical material includes remains recovered from sites in southern Peru and northwest Argentina ranging in date from 3,000 to 800 bp . Morphological and anatomical analyses were conducted on seeds, pericarps and peduncles (the stem of the flower or fruit) for reconstructing squash size and shape evolution under domestication. The results suggest the presence of hybrid forms, mainly from the earlier sites, but also from more recent ones. As expected, a linear evolutionary pathway was not found. Diversity and multiple crossings seem to have been a constant in squash cultivation over time, emphasising the role of gene flows between domestic and wild variants in the domestication process. Finally, we hypothesize the possible linkage between past gene flow and different dormancy patterns as part of management practices, allowing the maintenance of squash populations adapted to different environmental conditions.

Description: Until recently the plant economy of the Northern European Bronze Age was only investigated locally or within modern boundaries. New results from the project “Settlements of the Bronze Age” by the Academy of Science and Literature Mainz allow us to now fill part of the remaining gaps in research. Summarizing all available data concerning the plant economy of the Northern European Bronze Age has shown that it constitutes a time of innovation and continuous change. In addition to the omnipresent Triticum dicoccum (emmer) and Hordeum vulgare (barley), this period is marked by the emergence of various new cultivars like T. spelta (spelt) or Camelina sativa (gold-of-pleasure). A comparison between the cereal spectra from several regions in Northern Germany and Scandinavia revealed differences and similarities which allowed for the reconstruction of multiple possible contact zones and various influences from adjacent cultures. Northern Germany and especially Schleswig–Holstein served as an important link for trading over land and by water between the southern areas and Scandinavia. The rising diversity of crop plants in the Late Bronze Age, which is for the first time comparable to the southern regions, reflects the increased trade and therefore stronger influence from beyond the Northern European Bronze Age, which resulted in an accelerated assimilation of innovations and new technologies.

Description: We review the history of Quaternary pollen analysis from 1916 to the present-day, with particular emphasis on methodological and conceptual developments and on the early pioneers of the subject. The history is divided into three phases—the pioneer phase 1916–1950, the building phase 1951–1973, and the mature phase 1974–present-day. We also explore relevant studies prior to Lennart von Post’s seminal lecture in 1916 in Kristiania (Oslo) in an attempt to trace how the idea of Quaternary pollen analysis with quantitative pollen counting and stratigraphical pollen diagrams developed.

Description: The reaction of vegetation to past climate change provides important insights for vegetation responses to future climate change. A key problem for projections into the future is obtaining estimates of the rates at which plants are able to spread as their environment changes. To address this uncertainty, we review the palaeoecological and phylogeographic literature to estimate the range of observed rates of spread for the major European trees and discuss aspects of their postglacial spread. The review is illustrated with isochrone maps depicting the time when particular thresholds in pollen proportion were reached in pollen diagrams available from the European Pollen Database. We find that rates of at least 1,000 m year −1 were realised by early colonisers including Corylus and Ulmus , while trees spreading later into established woodlands, e.g. Quercus and Tilia , achieved rates of around 500 m year −1 . Phylogeographic investigations are available for most of the abundant European trees, often indicating that populations in the central and southern parts of the three south European peninsulas were not the origins for the postglacial colonization of central and northern Europe. In some cases, the results of these studies clearly show the direction of postglacial spread, while generally providing new information to help in interpreting pollen data. Phylogeographic results for Alnus suggest that the high apparent rates of postglacial spread are due to an initial spread at low population density and a later expansion. This decoupling between spread and population expansion is also seen for late expanding trees such as Picea, Fagus and Carpinus . Here, population expansion was probably not delayed by dispersal, but by a limiting climate as assumed by von Post. While the late Holocene expansion of Picea and Fagus in Sweden was important as a dating tool in the development of pollen analysis by von Post 100 years ago, we remain unable to determine which particular driver caused the late expansion of these two trees.

Description: Quantification of vegetation cover from pollen analysis has been a goal of palynologists since the advent of the method in 1916 by the great Lennart von Post. Pollen-based research projects are becoming increasingly ambitious in scale, and the emergence of spatially extensive open-access datasets, advanced methods and computer power has facilitated sub-continental analysis of Holocene pollen data. This paper presents results of one such study, focussing on the Mediterranean basin. Pollen data from 105 fossil sequences have been extracted from the European Pollen database, harmonised by both taxonomy and chronologies, and subjected to a hierarchical agglomerative clustering method to synthesise the dataset into 16 main groupings. A particular focus of analysis was to describe the common transitions from one group to another to understand pathways of Holocene vegetation change in the Mediterranean. Two pollen-based indices of human impact (OJC: Oleaceae, Juglans, Castanea ; API: anthropogenic pollen indicators) have been used to infer the degree of human modification of vegetation within each pollen grouping. Pollen-inferred cluster groups that are interpreted as representing more natural vegetation states show a restricted number of pathways of change. A set of cluster groups were identified that closely resemble anthropogenically-disturbed vegetation, and might be considered anthromes (anthopogenic biomes). These clusters show a very wide set of potential pathways, implying that all potential vegetation communities identified through this analysis have been altered in response to land exploitation and transformation by human societies in combination with other factors, such as climatic change. Future work to explain these ecosystem pathways will require developing complementary datasets from the social sciences and humanities (archaeology and historical sources), along with synthesis of the climatic records from the region.

Description: From the anthracological study of considerable quantities of charcoal recovered from the excavation of the settlement at Los Castillejos de Montefrío, a synthesis was made of the vegetation dynamics during Recent Prehistory of the area, from the middle of the sixth millennium bc to the beginning of the second millennium bc . The vegetation dynamics mark four anthracological phases over this sequence. From the Late Neolithic (end of the fifth millennium bc ) the influence of different activities such as livestock raising, burning and agriculture become evident in the development of the natural vegetation, altering species composition and appearance frequency. The last anthracological phase, MF4, spanning the second half of the third millennium bc , saw the regeneration of the tree vegetation as certain former activities ceased, indicating the environmental singularity of this enclave within the context of the southern Iberian Peninsula.

Description: With regard to Near Eastern archaeobotanical investigations, Lebanon is still underrepresented. Archaeobotanical data have been obtained from only a few excavation sites, mostly from the Phoenician settlement of Tell el-Burak. The site is situated on the southern coastal plain of Sidon, between Sidon and Tyre. Continuous sampling throughout six seasons of excavations have enabled the detailed investigation of the archaeobotanical material from the site. Due to the fine stratigraphic resolution there, it is possible to examine the development of agricultural resources through the 400 years of Phoenician occupation. Additionally, systematic sampling has allowed investigation of the spatial distribution of botanical remains within certain building structures. The combination of the archaeological results with the data from the charcoal and seeds reinforces the assumption that Tell el-Burak was established by the city of Sidon or the nearby city of Sarepta as a production and trade centre for wine and possibly olive oil. The agricultural resources of grapes and olives were most probably cultivated in the immediate vicinity of the settlement and probably along the western slopes of the hill country further inland.

Description: In the early 1980s Naomi Miller changed the field of palaeoethnobotany; her research into whether the ancient seed eaters of southwest Asia were human or herbivore opened an ongoing debate over the impact that burning of animal dung had on the formation of archaeobotanical assemblages, and how researchers can differentiate between human and animal food remains. As the number of systematic archaeobotanical studies across West Asia and many other parts of the world increase, we are continually confronted with the question of the significance of dung burning. Herd animal dung is the dominant fuel source in many parts of West Asia today and the high densities of seeds of wild plants in archaeobotanical assemblages suggest that people were using dung as fuel across Inner Asia for millennia. Seed assemblages that represent herd animal dung are assisting scholars in understanding palaeoecology and herd animal diet in the past as well as human economy and pasturing practices. However, interpreting these assemblages is not always simple and there are predictable biases that need to be taken into account, notably an overrepresentation of endozoochoric seeds (seeds dispersed through animal ingestion). In West Asia, the most prominent of such seeds in dung assemblages are from the Amaranthaceae family, notably Chenopodium .
