RESUMEN
The reconstruction of the settlement´s hinterland and acquisition of plant resources is one of the crucial questions in the field of environmental archaeology. Our study is focused on the reconstruction of the settlement's structure and character of the environment from which the site drew resources. These research questions were addressed by the interpretation of plant macroremains, charcoals, and the results of the spatial model. We have focused on the maximum size of the settlement that the surrounding countryside was able to withstand. Our results clearly demonstrated significant deforestation and intensive land use in the vicinity of the Late Bronze Age study site. As the weed taxa showed, a wide range of crops was grown in rather dry or less often in damp fields. Based on our archaeobotanical results, we were able to reconstruct several types of grasslands: dry pastures and fallow fields on plateaus and slopes, wet pastures or meadows in the floodplain. Acidophilous oak forests, alluvial forests, and shrubs were reconstructed as the most common forest habitats in the vicinity of the study site. Based on the archaeological knowledge of the region, we assume relatively low population density during the Late Bronze Age, and thus only a small part of the more or less forested landscape was significantly affected by human activities.

Europe's prehistory oversaw dynamic and complex interactions of diverse societies, hitherto unexplored at detailed regional scales. Studying 271 human genomes dated ~4900 to 1600 BCE from the European heartland, Bohemia, we reveal unprecedented genetic changes and social processes. Major migrations preceded the arrival of "steppe" ancestry, and at ~2800 BCE, three genetically and culturally differentiated groups coexisted. Corded Ware appeared by 2900 BCE, were initially genetically diverse, did not derive all steppe ancestry from known Yamnaya, and assimilated females of diverse backgrounds. Both Corded Ware and Bell Beaker groups underwent dynamic changes, involving sharp reductions and complete replacements of Y-chromosomal diversity at ~2600 and ~2400 BCE, respectively, the latter accompanied by increased Neolithic-like ancestry. The Bronze Age saw new social organization emerge amid a ≥40% population turnover.
RESUMEN
The archaeological site of Breznice (Czechia) represents one of the large settlements of the Late Bronze Age (Ha A2/B1, 14C: 1124-976 BC) in Bohemia. The site became known mainly for a high number of so-called 'trenches', oblong pit features (breadth around 1â¯m, length 4-7â¯m), remarkable not only for their specific shape but also for their contents (unusual amounts of pottery, daub, loom weights and other finds, often with traces of a strong fire). In 2018-20, a research project focusing on the study of the site was realized. Magnetometer survey became an integral part of the project since it represented a way to obtain an overall image of the site. A 5-channel fluxgate gradiometer from Sensys (Germany) was used; the vertical gradient of the Z component of the Earth magnetic field was measured. In total, the survey covered an area of over 17 hectares and included over 1.8 million measurements. Profiles were orientated from east to west and data taken bidirectionally (alternate lines in opposite directions), in a 0.5â¯×â¯0.2â¯m grid. The site is extraordinary due to the fact that all archaeological features discovered so far belong to a single archaeological period (Late Bronze Age). This makes the acquired data set exceptional. It can be further used by archaeologists and geophysicists, both to create alternative models of the dynamics of prehistoric settlements and to better understand the nature and interpretive possibilities of the magnetometer data in archaeology as such.
