“…Sanabria Marsh, Northwestern Iberia, 8,721 BP [ 67 – 69 ]) or France (e.g. Lignin Lake, Southern Alps, 7,545 BP [ 70 ]; Armorican massif, Western Atlantic region, ~8000 BP [ 71 ]) seem plausible. They might have contributed to the bidirectional colonization of Europe by walnut from western and eastern Mediterranean reservoirs with natural- or human-mediated bottlenecks.…”

“…Subsequent palynological finds demonstrated that J . regia may have survived the cold, dry glacial intervals in refugia located in southern Europe [ 12 – 14 ] and the Balkans [ 15 – 18 ] ( S1 Video ). Carpological fossils of walnut have been found in northeastern Italy (Sammardenchia, 7,550 BP) [ 19 ], Switzerland (near Lake Constance, ~ 6,000–4,350 BP) [ 20 ] and Slovenia (Hocevarica, 5,600–5,500 BP) [ 21 ].…”

Rethinking the history of common walnut (Juglans regia L.) in Europe: Its origins and human interactions

Common walnut (Juglans regia L) is an economically important species cultivated worldwide for its high-quality wood and nuts. It is generally accepted that after the last glaciation J. regia survived and grew in almost completely isolated stands in Asia, and that ancient humans dispersed walnuts across Asia and into new habitats via trade and cultural expansion. The history of walnut in Europe is a matter of debate, however. In this study, we estimated the genetic diversity and structure of 91 Eurasian walnut populations using 14 neutral microsatellites. By integrating fossil pollen, cultural, and historical data with population genetics, and approximate Bayesian analysis, we reconstructed the demographic history of walnut and its routes of dispersal across Europe. The genetic data confirmed the presence of walnut in glacial refugia in the Balkans and western Europe. We conclude that human-mediated admixture between Anatolian and Balkan walnut germplasm started in the Early Bronze Age, and between western Europe and the Balkans in eastern Europe during the Roman Empire. A population size expansion and subsequent decline in northeastern and western Europe was detected in the last five centuries. The actual distribution of walnut in Europe resulted from the combined effects of expansion/contraction from multiple refugia after the Last Glacial Maximum and its human exploitation over the last 5,000 years.

“…Furthermore, data related to the beginning of agricultural activities are discrete and still debated. Several studies based on pollen reconstructions from the Armorican Domain have reported the presence of Cerealia pollen grains in association with ruderal taxa such as Plantago lanceolata since the late Mesolithic (8700 cal BP) (Visset et al, 1996;Joly and Visset, 2009). These works suggested an early regional Neolithization.…”

International audienceRelationships between climate variations, vegetation dynamics, and early human activities during the Neolithic have been reconstructed from high-resolution pollen and foraminiferal records obtained from cores retrieved from coastal wetland located in southern Brittany (Guidel, NW France). Our data show that the area around Guidel corresponded to a dense temperate forest locally replaced by riparian forest in the marsh, without any human disturbance during the early Neolithic. During the mid-Neolithic, between 6500 and 5500 cal years BP, the first episode of probable human settlement is recorded, as suggested by the increase of anthropogenic plants. This early record of human impact is consistent with archeological studies that find a high concentration of funeral monuments around Guidel during this cultural period. This complex first phase is interrupted by the disappearance of anthropogenic influence coinciding with a cold/humid climate period in the region characterized by recurrent major storms. Then, at the transition between the middle to late Neolithic, at 5500 cal years BP, a second phase of human retreat is signaled by both vegetation dynamics and archeological records; this interval also coincides with a climatic deterioration marked by cold/humid conditions recorded in the region (Sorrel et al., 2012). The results of the present study imply that human settlement/departure over the Neolithic was probably influenced by climatic variations. During the Bronze Age, Iron Age, and Middle Ages, a progressive decline of the arboreal forest synchronous with an increase of anthropogenic plants, confirms the high and persistent human activity around the site. Furthermore, our results at Guidel suggest a different anthropogenic trend recorded between north and south Brittany. The human impact is well recorded during the Neolithic at Guidel, while in northern Brittany human settlement is not recorded before the Bronze Age, consistent with existing archeological data.

“…Despite its limitations, therefore, the palynological method has the advantage that it may be used to define the full ecological context of early farming, and can stimulate debate on what can be a controversial subject (Behre 2007;Tinner et al 2007). Thus unusually early cereal-type pollen identified in Maritime Europe, at Vertonne in the Armorica region of France (Joly and Visset 2009), although perhaps belonging to halophytic grasses of the taxa discussed by Hall et al (1993), might also relate to early farming traces given associated disturbance taxa. It is noted that Joly et al (2007) produced a major work on comparative morphology of wild versus cultivated types based on glycerol pollen preparations, and has identified major vegetation disturbance in these same Cerealia-type spectra from Vertonne and other Armorica sites.…”

On the distinction of pollen grains of early varieties of Hordeum from Glyceria species: addressing the early cereal cultivation problem in palynology

Pollen grains of primitive varieties of Hordeum vulgare collected by the Gene bank of the Crop Research Institute, Prague are compared to pollen of native Glyceria species of the United Kingdom with a view to establishing separation criteria. It is found that a separation of Hordeum vulgare from both Glyceria maxima and Glyceria fluitans is possible according to annular characteristics in combination with grain size as dependent variables. These findings have implications for the identification of cerealtype pollen grains which could be evidence for early cultivation in the Terminal Mesolithic of northwest Europe, and for the use of palynology as a reliable source of palaeobotanical data, particularly in its inland areas. A phase of vegetation disturbance from the pollen site of Dog Hill in the southern Pennine uplands of the UK, an area with a high density of 'rod' microlith flint sites, is introduced as a case example using the above protocol. Here multiple Hordeum-type grains are encountered alongside prominent pollen indicators of disturbance, but also including non-pollen palynomorphs and microcharcoal data, at a date well before the mid-Holocene decline in Ulmus pollen frequencies which is often regarded as marking the beginning of the Neolithic. Secure identification of cereal-type pollen will greatly assist the understanding of the introduction of cultivation and the Mesolithic-Neolithic transition in northwest Europe.
