Article Reference Octet Stream Neolithic woodland management and land-use in south-eastern Europe: The anthracological evidence from Northern Greece and Bulgaria
Wood charcoal (anthracological) remains accumulated in archaeological deposits provide a valuable tool for reconstruction of past local vegetation and its use. They can offer evidence complementary to pollen analysis or be the main source on past vegetation change in areas where no pollen preservation is available. The current study assembles the anthracological evidence from 18 Neolithic sites situated in the zone spanning between the Lower Danube plain and the Aegean coast. This evidence is presented within the broader archaeological and paleoecological context of the region and in cal. years BC and/or BP. The data is interpreted in terms of land-use related to woodland management and exploitation of woodland resources during three chronological phases which could be distinguished within the Neolithic of south-eastern Europe: a) 6500-5800 cal. BC, b) 5800-5500 cal. BC, and c) 5500-4900 cal BC). The main vegetation type targeted by the Neolithic population were the thermophilous, mixed deciduous oak communities, which contained a rich and diverse undergrowth of light-demanding and fruit/nut bearing trees, shrubs and herbs. Those plant communities were the major source of fuel wood, forest pasture, fodder, gathered fruits, etc. The analyses indicate stability and sustainability of the firewood procurement and woodland management practices for the whole considered period and further suggest that the Neolithic land-use strategies favoured the rich and often fruit-bearing undergrowth of the oak forests and woodland.

Article Reference A survey of transposon landscapes in the putative ancient asexual ostracod Darwinula stevensoni
How asexual reproduction shapes transposable element (TE) content and diversity in eukaryotic genomes remains debated. We performed an initial survey of TE load and diversity in the putative ancient asexual ostracod Darwinula stevensoni. We examined long contiguous stretches of DNA in clones from a genomic fosmid library, totaling about 2.5 Mb, and supplemented these data with results on TE abundance and diversity from an Illumina draft genome. In contrast to other TE studies in putatively ancient asexuals, which revealed relatively low TE content, we found that at least 19% of the fosmid dataset and 26% of the genome assembly corresponded to known transposons. We observed a high diversity of transposon families, including LINE, gypsy, PLE, mariner/Tc, hAT, CMC, Sola2, Ginger, Merlin, Harbinger, MITEs and helitrons, with the prevalence of DNA transposons. The predominantly low levels of sequence diversity indicate that many TEs are or have recently been active. In the fosmid data, no correlation was found between telomeric repeats and non-LTR retrotransposons, which are present near telomeres in other taxa. Most TEs in the fosmid data were located outside of introns and almost none were found in exons. We also report an N-terminal Myb/SANT-like DNA-binding domain in site-specific R4/Dong non-LTR retrotransposons. Although initial results on transposable loads need to be verified with high quality draft genomes, this study provides important first insights into TE dynamics in putative ancient asexual ostracods.

Article Reference Octet Stream The worked bone industry and intrusive fauna associated with the prehistoric cave burials of Abri des Autours (Belgium)
ABSTRACT The excavation of the Abri des Autours, a rock-shelter located in southern Belgium, enabled the discovery of three human burials, two dated to the Early Mesolithic and a third dated to the Middle Neolithic. In addition to the human bones, more than 200 faunal remains were uncovered. A taphonomic analysis was undertaken to determine whether their presence resulted from anthropogenic activities and whether they are linked to the burials. Two assemblages were distinguished. The majority of the fauna corresponds to remains of animals found scattered throughout the cave, including in the Mesolithic levels. These are mainly portions of carcasses brought in to the rockshelter by scavengers or predators. Therefore, their deposition did not result from human activity. Thus far, no animal bone had been found in direct association with Mesolithic burials in Belgium, and this site conforms to that pattern. Moreover, this interpretation corroborates the archaeological study, which did not uncover any traces of domestic activity in the cave, during either the Mesolithic or the Neolithic. On the other hand, several bone artefacts, including various tools and a pendant, were also identified. With the exception of an isolated artefact, all of these were clearly associated with the Middle Neolithic burial (Michelsberg culture). This is only the fourth Neolithic cave burial to have yielded animal bone artefacts in Belgium. A preliminary micro-wear analysis has confirmed that these objects had been used before being deposited and has allowed us to propose several hypotheses concerning their original use.

Article Reference Stratigraphy and depositional environments of the Late Famennian (Late Devonian) of Southern Belgium and characterization of the Strud locality
The Famennian (Upper Devonian, c. 372 to 359 Ma) strata of Belgium have recently received much attention after the discoveries of early tetrapod remains and outstandingly preserved continental arthropods. The Strud locality has yielded a diverse flora and fauna including seed-plants, tetrapods, various placoderm, actinopterygian, acanthodian and sarcopterygian fishes, crustaceans (anostracans, notostracans, conchostracans and decapods) and a putative complete insect. This fossil assemblage is one of the oldest continental – probably fresh-water – ecosystems with a considerable vertebrate and invertebrate diversity. The study of the palaeoenvironment of the Strud locality is crucial because it records one of the earliest and most important phases of tetrapod evolution that took place after their emergence but before their terrestrialization. It raises the question of environmental and ecological conditions for the Devonian aquatic ecosystem and the selection pressures occurring at the onset of tetrapod terrestrialization. The present study characterized the fluvial facies of the Upper Famennian sedimentary rocks of Strud and the surrounding areas. The exceptional preservation of arthropods and plants in the main fossiliferous layers is explained by rapid burial in the fine-grained sediment of the quiet and confined flood plain environment. Newly investigated fossiliferous sections in the Meuse–Samson area led to the description and correlation of key sections (Strud, Wierde and Jausse sections, complemented by the less continuous Haltinne, Huy and Coutisse sections). Moreover, the investigated sections allowed a review of the age of the fossiliferous horizon, which is now definitely considered to be Late Famennian in age.

Article Reference Brabantophyton, a new genus with stenokolealean affinities from a Middle to earliest Upper Devonian locality from Belgium
A new taxon with stenokolealean affinities, Brabantophyton runcariense gen. et sp. nov., is described from seven pyrite permineralized axes collected from the mid Givetian to earliest Frasnian (late Middle to earliest Upper Devonian) locality of Ronquières (Belgium). The specimens include stems and lateral organs. The stems are characterized by a protostele dissected into three primary ribs, each of them dividing into two secondary ribs. The protostele shows a central protoxylem strand and numerous strands distributed along the midplanes of the ribs. The vascular supply to lateral organ is composed of two pairs of traces, produced at the same time by the two ribs issued from a single primary rib of the protostele. Within each pair, the shape and the size of the traces are unequal: one is T-shaped and the other is oval to reniform. The T-shaped traces of each pair face each other. The inner cortex of the lateral organs is parenchymatous and the outer cortex is sparganum-like. The specimens of Brabantophyton runcariense show many similarities with the stenokolealean genus Crossia virginiana Beck and Stein, but the vascular supply of lateral organs of the latter consists of a more symmetrical and distinctively simpler pair of traces. Brabantophyton represents the first report of the Stenokoleales in southeastern Laurussia. The characteristics of the Brabantophyton protostele compare better with the anatomy of the radiatopses, and, within the latter, particularly with basal seed plants.

Article Reference New information, including anatomy of the secondary xylem, on the genus Brabantophyton (Stenokoleales) from Ronquières (Middle Devonian, Belgium)
Two pyrite permineralized stems and one root are reported from the upper Middle to lowermost Late Devonian (middle Givetian to lowermost Frasnian) locality of Ronquières (Belgium) and identified as Brabantophyton runcariense Momont et al. (Stenokoleales). The stems include a three-ribbed protostele with a central protoxylem strand and other strands disposed along the midplanes of the ribs; each specimen shows secondary xylem. Tracheids of both primary and secondary xylem show circular to elliptical, multiseriate bordered pits. Rays are 1–seriate to 4–seriate; their height is highly variable, ranging from 3 to more than 100 cells. The root includes a four-ribbed protostele. Each rib shows two exarch protoxylem strands. The root also comprises a ring of secondary xylem identical to that of the stems. The characteristics of the secondary vascular anatomy of Brabantophyton appear closer to the seed plants than to any other Devonian plant lineage. However, the presence of a bifacial vascular cambium is not demonstrated, which precludes a definitive assignment of the genus to the lignophytes. A hypothesis about the ontogenetic development of Brabantophyton is proposed on the basis of the different characteristics observed in the different stem specimens of the plant.
