Inproceedings Reference Land Subsidence Observed in the Merchtem Area (Flanders) – 30 Years of SAR Data Associated to Groundwater Withdrawal?
A land subsidence affecting several towns at the joining limits of the Belgian Provinces of East Flanders, Antwerp and Flemish Brabant is followed during the last three decades. ERS 1–2, ENVISAT, TerraSAR-X and Sentinel-1A satellites SAR scenes were processed from 1992 till October 2020 to map the land subsidence evolution. The subsidence corresponds to a surface area of 220 km 2 during the ERS 1/2 time interval distributed over three distinct subsidence bowls. During the ENVISAT and TerraSAR-X time interval, only one residual subsidence bowl was mapped affecting a surface area of about 70 km 2 . Several towns (Londerzeel and Steenhuffel) remained in the center of the subsidence bowl. The annual average negative velocity values range between −5.99 and −0.5 mm/year. During the Sentinel-1A period, the subsidence bowl has lost half of its surface reaching 36 km 2 . The LOS velocity values have also decreased during the period 2016–2020.

Article Reference Landwirtschaft und Landnutzung in der Region von Ovčarovo-Gorata: archäobotanische Forschungen zum Frühneolithikum in Nordostbulgarien
There is no archaeobotanical evidence from the site Ovčarovo-Gorata. During the excavations of the site in the 1970ties neither archaeobotanical sampling nor survey for pollen analysis in the surrounding were conducted. Those research gaps could partly be compensated by the archaeobotanical studies on the Neolithic settlements of Orlovec, Koprivec, Samovodene und Džuljunica carried out in the period of 1996-2006. The paleobotanical evidence from those sites allows to reconstruct the agriculture and land use in the region of Ovčarovo-Gorata during the Neolithic and to put them in a regional context. The current study is based on identification and analysis of charred (and few mineralised) plant remains, like seeds/fruits and charred wood. Those plant remains were extracted from the sediment samples (average volumes 10-20 litre) using manual floation. The here considered archaeobotanical data includes 31 samples, with total volume of 430 l and containing over 2400 identified plant remains. The archaeobotanical finds were analysed with the help of binocular and reflected light microscope, as well as corresponding identification literature and reference materials from the herbarium at the Department of Botany of the Sofia University. The early Neolithic samples from Džuljunica, Orlovec and from the oldest layers of Koprivec could be considered as synchronous and belong to the earliest phase of the Neolithic in the region (ca. 6100-5700 calBC). The samples from the early Neolithic layers of Samovodene (horizon 11-8) belong to the developed early Neolithic and are considered as contemporary with the period Karanovo II in Thrace and correspondently to the occupation of Ovčarovo-Gorata (ca. 5700-5400 calBC). Few of the samples (n=4) come also from the Late Neolithic (ca. 5400-4800 calBC) in the region, from Samovodene (horizon 5-3) and from Koprivec. The results of the archaeobotanical studies show the combination of the three main cereal crops (einkorn, emmer and barley) known also from the early Neolithic of Thessaly and Anatolia. In the samples from northeast Bulgaria the dominating cereal crop is the hulled barley, what is a clear difference from the southern parts of Bulgaria where in the early Neolithic the dominating cereal crops are hulled wheats – einkorn and emmer. The further principal crops, typical for the Neolithic period, are also found in the earliest phases of the Neolithic in the region. Those are a variety of pulses (lentil, pea and grass pea) as well as flax. In the late Neolithic samples there are also finds of bitter vetch. The wide spectrum of gathered plants (at least 11 taxa) reflects also the use of the natural vegetation resources from a variety of habitats in the surrounding. Further evidence which could be used for reconstructing the vegetation and land use in the Neolithic are the wood charcoal identifications from Džuljunica. Considering those sources of information it could be concluded that in the surrounding of the sites apart of oak forests also open vegetation, riparian forests and wetlands were developed. The relative open vegetation in the surrounding of the early Neolithic settlements could be one of the reasons why the corresponding locations were chosen by the Neolithic people to settle there. On the other hand this open vegetation could be caused by the Neolithic land use and animal husbandry, which have also led to certain reduction of the forests in the immediate surroundings of the settlements.

Article Reference Lanice conchilega structures carbon flows in soft-bottom intertidal areas
Biogenic reefs constructed by the tube-building ecosystem engineer Lanice conchilega (Terrebilidae, Polychaeta) have profound structuring impacts on the benthic environment in that they alter the biogeochemical and physical properties of the sediment. This study provides new insights into the functioning and effects on food webs of L. conchilega reefs in intertidal sediments using linear inverse models to quantify the carbon flows in the food webs in the presence and absence of the tubeworm. The inverse food web models were based on an empirical dataset from 2 study sites, which provided biomass and stable isotope data, and information on general physiological constraints from the literature. Results of the model showed that the carbon input into reef food webs (mean ± SE; 191 ± 50 mmol C m−2 d−1) is ca. 40 times higher compared to bare sand areas (5 ± 2 mmol C m−2 d−1) and is mainly derived from organic matter (OM) in the water column. Most of the OM input towards these reefs is consumed by suspension-feeding macrofauna, particularly L. conchilega; however, the worm is not an important source of carbon for other macrofaunal organisms. The ratio of OM input to primary production indicates that the OM needs to be produced in an area at least 15 times larger than the reef area, demonstrating significant OM ‘focussing’ within the reef food web. The reef structures created by L. conchilega act as a trap for OM, resulting in an overall higher macrofaunal biomass and much more diverse food webs than in the absence of the tubeworm.

Article Reference Large canids at the Gravettian Předmostí site, the Czech Republic: The mandible
Efforts to identify Paleolithic dogs or incipient dogs have been based mainly on examination of complete or nearly complete crania. Complete skulls are, however, very rare in the archaeological record. Because canid mandible are far more frequently found in Pleistocene assemblages, the objective of this study is to investigate whether it is possible to differentiate these jaws by metric and osteomorphological methods in two morphotypes: Paleolithic dogs and Pleistocene wolves. This paper is mainly based on the very rich canid assemblage from the Gravettian Předmostí site in the Czech Republic, but also includes a few mandible from several other European Paleolithic sites. This study provides additional evidence of the existence at Předmostí of the two canid morphotypes. The metric data indicate that the mandible of the Paleolithic dogs are shorter than those from Pleistocene wolves in all tested measurements of length, and the carnassial crown length is shorter in Paleolithic dogs compared with the length of this tooth in Pleistocene wolves. Furthermore, in eight of nine indexes, the Paleolithic dogs differ significantly from the Pleistocene wolves. The mandible of Paleolithic dogs differ also in non-metric features from the Pleistocene wolves: they present a high frequency of crowded premolars and backwards-oriented apex of the coronoid. This paper furthermore confirms that Paleolithic dogs occur at two late Upper Paleolithic sites (Eliseevichi, Verholenskaya) where previous studies had indicated their presence. In addition, we document the presence of Paleolithic dogs at another Gravettian site, Kostenki-8.
