First isotope analysis and new radiocarbon dating of Trypillia (Tripolye) farmers from Verteba Cave, Bilche Zolote, Ukraine

This paper presents an analysis of human and animal remains from Verteba cave, near Bilche Zolote, western Ukraine. This study was prompted by a paucity of direct dates on this material and the need to contextualise these remains in relation both to the transition from hunting and gathering to farming in Ukraine, and their specific place within the Cucuteni-Trypillia culture sequence. The new absolute dating places the remains studied here in Trypillia stages BII/CI at c. 3900–3500 cal BC, with one individual now redated to the Early Scythian period. As such, these finds are even more exceptional than previously assumed, being some of the earliest discovered for this culture. The isotope analyses indicate that these individuals are local to the region, with the dietary stable isotopes indicating a C3 terrestrial diet for the Trypillia-period humans analysed. The Scythian period individual has δ13C ratios indicative of either c. 50% marine, or alternatively C4 plant inputs into the diet, despite δ18O and 87Sr/86Sr ratios that are comparable to the other individuals studied.

THE SPATIAL AND TEMPORAL DIFFUSION OF STYLISTIC INNOVATIONS IN MATERIAL CULTURE

Many explanations for the sigmoid or S-shaped curves that characterize the diffusion of innovations through time have been proposed. Recent studies demonstrate that social learning mechanisms, including conformist strategies, and heterogeneous adoption thresholds related to economic inequality and the decreasing cost of goods can generate these S-shaped cumulative frequency curves. The present study of a regional material culture sequence expands our inquiry concerning the underlying social forces that structure diffusion through both space and time. Using historic New England gravestones and their associated documents, this study considers both cultural transmission between stone carvers and consumer choices. Social learning among consumers can generate both wave-like diffusion patterns through space and lead to the persistence of cultural variants in certain locales.

Excavations at Sos Höyük 1994: First Preliminary Report

Collaborative Australian–Turkish archaeological investigations in north-eastern Anatolia, begun in 1988 in the Bayburt province (then an ilçe of Gümüşhane), continued for six weeks during June–July 1994 with excavations at Sos Höyük near Erzurum. The decision to extend the limits of the research project beyond the Bayburt plain, eastwards into the adjacent province, was based primarily on the need to address questions raised by our work in Bayburt, most notably the apparent gaps in its culture sequence. Further, we were acutely aware that in order to establish a sequence for north-east Anatolia we would need to reexamine by systematic excavations the human settlement of the Erzurum plain, long known from the early campaigns of H. Z. Koşay and his colleagues at Karaz, Güzelova and Pulur, and I. K. Kökten's pioneering surveys. Our interest in the site of Sos Höyük was roused by material excavated during a three week campaign in the summer of 1987 by a team from Atatürk University (Erzurum) and Erzurum museum. While some of the material clearly keyed into the Bayburt sequence, much of it did not. A visit to the site revealed a dense surface scatter of artefacts, especially obsidian, and substantial stratified deposits exposed by the diggings of the local villagers. The potentialities of the site were clear. With the material excavated at Büyüktepe and collected in the Bayburt province overlapping and complementing that at Sos, we would move closer toward an understanding of cultural developments in north-east Anatolia.

A cyclic AMP-responsive element-binding transcriptional activator in Drosophila melanogaster, dCREB-A, is a member of the leucine zipper family.

In this report, we describe the isolation and initial characterization of a Drosophila protein, dCREB-A, that can bind the somatostatin cyclic AMP (cAMP)-responsive element and is capable of activating transcription in cell culture. Sequence analysis demonstrates that this protein is a member of the leucine zipper family of transcription factors. dCREB-A is unusual in that it contains six hydrophobic residue iterations in the zipper domain rather than the four or five commonly found in this group of proteins. The DNA-binding domain is more closely related to mammalian CREB than to the AP-1 factors in both sequence homology and specificity of cAMP-responsive element binding. In embryos, dCREB-A is expressed in the developing salivary gland. A more complex pattern of expression is detected in the adult; transcripts are found in the brain and optic lobe cell bodies, salivary gland, and midgut epithelial cells of the cardia. In females, dCREB-A is expressed in the ovarian columnar follicle cells, and in males, dCREB-A RNA is seen in the seminal vesicle, ejaculatory duct, and ejaculatory bulb. These results suggest that the dCREB-A transcription factor may be involved in fertility and neurological functions.
