The excavation of the Wattendorf-Motzenstein Corded Ware settlement in Franconia (Germany) has yielded new information with regard to the architecture, economy, and ritual activities, as well as the social organisation of Final Neolithic groups in Central Europe. The settlement is dated to 2660–2470 cal BC and was an agrarian community. Detailed analyses of the material culture combined with biological and pedological parameters allowed new interpretations regarding Corded Ware economies as well as domestic and ritual spheres. The settlement contained about 35 individuals at most, who were organised in fewer than eight households. The exceptional results obtained call for further research strategies to be developed.

The assessment of the genetic diversity of cultivated varieties is a very important element of breeding programs. This allows the determination of the level of genetic differentiation of cultivated varieties, their genetic distinctiveness, and is also of great importance in the selection of parental components for crossbreeding. The aim of the present study was to determine the level of genetic diversity of oat varieties currently grown in Central Europe based on two marker systems: ISSR and SCoT. The research conducted showed that both these types of markers were suitable for conducting analyses relating to the assessment of genetic diversity. The calculated coefficients showed that the analyzed cultivars were characterized by a high genetic similarity. However, the UPGMA and PCoA analyses clearly indicated the distinctiveness of the breeding programs conducted in Central European countries. The high genetic similarity of the analyzed forms allow us to conclude that it is necessary to expand the genetic pool of oat varieties. Numerous studies show that landraces may be the donor of genetic variation.

Abstract The article deals with Czech and German nationalist discourses and practices in the late 19th and early 20th centuries as they relate to tourism in the Krkonoše/Riesengebirge, the highest Central European mountain range between the Alps and Scandinavia. It will discuss the discourses developed in relation to mountain tourism and nationalism (metaphors of battlefields, wedges, walls, gates, and bastions), different symbolical cores of mountains, and practices of tourist and nationalist organizations (tourist trails and markings, excursions, the ownership of mountains huts, languages used, memorials, and the construction of roads). It will examine how these discourses and practices changed from the first Czech-German ethnic conflicts in the 1800s until the end of interwar Czechoslovakia. Finally, it will discuss the Czech culture of defeat in the shadow of the Munich Agreement, which meant the occupation of the Giant Mountains by Nazi Germany.

Genotype-by-sequencing (GBS) was used to explore the genetic diversity and structure of Spinacia turkestanica, and the selective sweeps involved in domestication of cultivated spinach, S. oleracea, from S. turkestanica. A total 7,065 single nucleotide polymorphisms (SNPs) generated for 16 Spinacia oleracea and 76 S. turkestanica accessions placed the S. oleracea accessions in one group, Q1, and the 76 S. turkestanica accessions, which originated from Central Asia, in two distinct groups, Q2 and Q3. The Q2 group shared greater genetic identity with the S. oleracea accessions, Q1, than the Q3 S. turkestanica group. Likewise, the S. oleracea Q1 group had a smaller Fst (0.008) with the Q2 group than with the Q3 group (Fst = 0.012), and a greater gene flow (Nm = 30.13) with the Q2 group than with the Q3 group (Nm = 21.83). The Q2 accessions originated primarily from Uzbekistan while the Q3 accessions originated mostly from Tajikistan. The Zarafshan Mountain Range appears to have served as a physical barrier that largely separated members of the Q2 and Q3 groups of S. turkestanica. Accessions with admixtures of Q2 and Q3 were collected primarily from lower elevations at the southern end of the Zarafshan Mountain Range in Uzbekistan. Selective sweep regions identified at 32, 49, and 52 Mb on chromosomes 1, 2, and 3, respectively, appear to have played a vital role in the domestication of S. oleracea as they are correlated with important domestication traits, including day length sensitivity for bolting (flowering). High XP-CLR scores at the 52 Mb genomic region of chromosome three suggest that a selective sweep at this region was responsible for early differentiation of S. turkestanica into two groups in Central Asia.
