Palaeoenvironment, Settlement, and Land Use in the Late Neolithic—Bronze Age Site of Colombare di Negrar di Valpolicella (N Italy, On-Site)
Palynological and archaeobotanical analyses have been carried out as part of the interdisciplinary
project of Colombare di Negrar, a prehistoric site in the Lessini Mountains (northern Italy).
The palaeoenvironmental and economic reconstruction from the Late Neolithic to the beginning of
the Early Bronze Age was based on 16 pollen samples and three samples of macroremains taken from
two contiguous trenches. The landscape reconstruction shows the presence of natural clearings in the
wood. Forest cover was characterised by oak wood, with Ulmus and Tilia. The intermediate morphology
of size and exine of Tilia cordata/platyphyllos pollen may be regarded as the first palynological
evidence of lime hybrids in palaeorecords. Hygrophilous trees and Vitis vinifera testify to the presence
of riparian forests and moist soils. Among trees supplying fruits, in addition to the grapevine, hazelnut
(Corylus avellana) and walnut (Juglans regia) were present. A mixed economy based on animal
breeding and cultivation of cereals (Hordeum vulgare, Triticum monococcum, T. dicoccum, T. timopheevii)
emerged from the data. The combined analysis of pollen and plant macroremains suggests that
different activities were carried out simultaneously in Colombare and a relationship between natural
resources and the socio-economic and cultural evolution of the territory
The SUCCESSO-TERRA Project: a Lesson of Sustainability from the Terramare Culture, Middle Bronze Age of the Po Plain (Northern Italy)
This backstory article deals with the SUCCESSO-TERRA Project (2017–2020), an interdisciplinary
research program aiming at reconstructing the land-use transformations that occurred during the
development of the Terramare culture in the southern-central Po Plain of Northern Italy. Topics
include climate-environment changes, human impact and exploitation of natural resources that
are interconnected topics in human ecology and environmental sciences. These topics can only be
understood in a long-term perspective integrating archaeology, geology, botany and other sciences. The
text includes the theoretical basis, the research strategy and the main methodological approaches given
by geoarchaeology and palynology, the two research sides constituting the partnership of the project
The Botanical Record of Archaeobotany Italian Network - BRAIN: a cooperative network, database and website
Con autorización de la revista para autores CSIC[EN] The BRAIN (Botanical Records of Archaeobotany Italian Network) database and network was developed by the cooperation of archaeobotanists working on Italian archaeological sites. Examples of recent research including pollen or other plant remains in analytical and synthetic papers are reported as an exemplar reference list. This paper retraces the main steps of the creation of BRAIN, from the scientific need for the first research cooperation to the website which has a free online access since 2015.Peer reviewe
The Eurasian Modern Pollen Database (EMPD), version 2
The Eurasian (née European) Modern Pollen Database (EMPD) was established in 2013 to provide a public database of high-quality modern pollen surface samples to help support studies of past climate, land cover, and land use using fossil pollen. The EMPD is part of, and complementary to, the European Pollen Database (EPD) which contains data on fossil pollen found in Late Quaternary sedimentary archives throughout the Eurasian region. The EPD is in turn part of the rapidly growing Neotoma database, which is now the primary home for global palaeoecological data. This paper describes version 2 of the EMPD in which the number of samples held in the database has been increased by 60 % from 4826 to 8134. Much of the improvement in data coverage has come from northern Asia, and the database has consequently been renamed the Eurasian Modern Pollen Database to reflect this geographical enlargement. The EMPD can be viewed online using a dedicated map-based viewer at https://empd2.github.io and downloaded in a variety of file formats at https://doi.pangaea.de/10.1594/PANGAEA.909130 (Chevalier et al., 2019)Swiss National Science Foundation | Ref. 200021_16959
LESSONS FROM THE PAST FOR A SUSTAINABLE FUTURE: INTERPRETATION OF NEAR-SITE PALYNOLOGICAL DATA
POLLEN AND LIPID BIOMOLECULES FROM SEDIMENTARY ARCHIVES: A CASE STUDY FROM THE NEAR-SITE CORES OF THE TERRAMARA S. ROSA DI POVIGLIO (PO PLAIN, N ITALY)
Pollen and Molecular Biomarkers from Sedimentary Archives in the Central Po Plain (N Italy): Assessing Their Potential to Deepen Changes in Natural and Agricultural Systems
This paper proposes to improve the information provided by biological indicators from sedimentary archives by integrating biomolecular techniques and botanical skills. This study represents a first proposal for combining pollen and biomolecular markers to detect land use and improve knowledge of past environmental change drivers. The specific aim of the research is to verify the relationship between miliacin (a pentacyclic triterpene methyl ether, usually interpreted as a broomcorn millet biomarker) and Panicum pollen in three near-site stratigraphic sequences of the Terramara S. Rosa di Poviglio (Po Plain, N Italy). The three cores span the last ~15,000 years and potentially record the beginning of Panicum miliaceum cultivation attested in the area since at least the Bronze Age within the Terramare culture. Despite the fact that Panicum pollen grains were rare in the spectra and miliacin was barely detectable in most of the 31 samples selected for biomolecular analyses, their combined evidence testifies to the local presence of the plant. Panicum pollen and sedimentary miliacin suggest the adoption of millet crops during the Recent Bronze Age by the Terramare culture, when climatic instability led to the diversification of cereal crops and the shift to drought-tolerant varieties
Palynological approach to reconstruct pastoral activities: case studies from Basilicata, South Italy
A palynological approach to the study of Mediterranean landscapes is ideally suited for detecting the land-use history and environmental changes that gave rise to the present-day Mediterranean landscape. In particular, the combined evidence of pollen and non-pollen palynomorphs (NPPs, such as fungal spores and algal elements) from archaeological sites is useful for tracing the impact of past human activities on the environment, and also to discriminate past land uses and pastoral practices. In Italy, an outstanding number of studies that include pollen or other plant remains from archaeological contexts (BRAIN database: brainplants.successoterra.net; [1]) have testified to the widespread occurrence of pastoral activities on the peninsula over the last few millennia. This contribution reports on palynological evidence for the impact of centuries of grazing on the vegetation of Basilicata, a region of southern Italy where animal breeding and pastoralism have a long tradition. The integrated analyses of microscopic records from eight archaeological sites (dated from the 6th century BC to the 15th century AD) indicate wide and continuous pastoral activities practiced in the region [2]. The combined evidence from pollen pasture indicators and NPP markers of grazing (mainly coprophilous fungal spores) point out that pastures were the main type of land-use in the territory surrounding each of the eight study sites. As evidenced by the pollen records, this region has long been a grazed area, with more intense pastoral activities documented from the end of the Hellenistic age to the Medieval and Renaissance periods. This research confirms the economic importance of pastoralism in the past communities and its prominent role in shaping the Italian landscape
Sharing the Agrarian Knowledge with Archaeology: First Evidence of the Dimorphism of Vitis Pollen from the Middle Bronze Age of N Italy (Terramara Santa Rosa di Poviglio)
The recovery of inaperturate pollen from functionally female flowers in archaeological layers opens the question of a possible pollen-based discrimination between wild and domesticated Vitis vinifera in prehistoric times. Pollen analysis applied to archaeology has not routinely considered the existence of pollen dimorphism in Vitis, a well-known trait in the field of agrarian studies. Therefore, the inaperturate shape of grapevine pollen is ignored by studies on the archaeobotanical history of viticulture. In this paper we investigate pollen morphology of the domesticated and wild subspecies of V. vinifera, and report the first evidence of inaperturate Vitis pollen from an archaeological site. We studied exemplar cases of plants with hermaphroditic flowers, belonging to the subspecies vinifera with fully developed male and female organs, cases of dioecious plants with male or female flowers, belonging to the wild subspecies sylvestris and cases of V. vinifera subsp. vinifera with morphologically hermaphroditic but functionally female flowers. The pollen produced by hermaphroditic and male flowers is usually trizonocolporate; the pollen produced by female flowers is inaperturate. This paper reports on the inaperturate pollen of Vitis found in an archeological site of the Po Plain, Northern Italy. The site dated to the Bronze Age, which is known to have been a critical age for the use of this plant with a transition from wild to domesticated Vitis in central Mediterranean. Can the inaperturate Vitis pollen be a marker of wild Vitis vinifera in prehistoric times? Palynology suggests a possible new investigation strategy on the ancient history of the wild and cultivated grapevine. The pollen dimorphism also implies a different production and dispersal of pollen of the wild and the domesticated subspecies. Grapevine plants are palynologically different from the other Mediterranean “cultural trees”. In fact, Olea, Juglans and Castanea, which are included in the OJC index, have the same pollen morphology and the same pollen dispersal, in wild and domesticated plants. In contrast, the signal of Vitis pollen in past records may be different depending on the hermaphroditic or dioecious subspecies
