Published: June 2012

BackgroundIncreased sensitivity and exposure to stress are associated with psychotic symptoms in schizophrenia and its risk states, but little is known about the co-evolution of stress sensitivity and exposure with positive and other symptoms in a clinical high-risk (CHR) cohort.MethodA combined cross-sectional and longitudinal design was used to examine the associations over time of stress sensitivity and exposure (i.e. life events) with ‘prodromal’ symptoms in a cohort of 65 CHR patients assessed quarterly for up to 4 years, and at baseline in 24 healthy controls similar in age and gender.ResultsImpaired stress tolerance was greater in patients, in whom it was associated over time with positive and negative symptoms, in addition to depression, anxiety and poor function. By contrast, life events were comparable in patients and controls, and bore no association with symptoms. In this treated cohort, there was a trajectory of improvement in stress tolerance, symptoms and function over time.ConclusionsImpaired stress tolerance was associated with a wide range of ‘prodromal’ symptoms, consistent with it being a core feature of the psychosis risk state. Self-reported life events were not relevant as a correlate of clinical status. As in other treated CHR cohorts, most patients improved over time across symptom domains.
Trading implements in early Troy
Authors: Bobokhyan A. 
Published: June 2012

AbstractThe traditional view of Troy as a kind of central site presupposes balance weights and other artefacts that attest weighing procedures among the excavated material. Indeed, already in the works of Homer it is possible to find references to premonetary aspects (for example, the gold standard τάλαντον). The main purpose of this investigation is to provide an archaeological view on the issue of trading implements and their significance in early Troy. The principal group of objects defined as balance weights was unearthed during the excavations of Heinrich Schliemann. By contrast, very little data derive from Wilhelm Dörpfeld's activities at the site. Balance weights are known also from the recent excavations of Manfred Korfmann. In two previous reports I presented the state of balance weights found in the Schliemann and Korfmann excavations (Bobokhyan 2006; 2008a). The aim of this article is to consider the main stages of the investigation of balance weights, with special reference to the excavations of Carl Blegen in Troy. The main problem related to the study of the Trojan balance weights is the lack of knowledge about the archaeological contexts for many of the finds. A considerable number of these implements has been lost or is inaccessible. However, their compilation assists in understanding the abstract way-of-thinking and value perception of the population of ancient Troy. The actual number of balance weights from Troy can be estimated at ca 100. The main period of their appearance is during Troy II–V, less in Troy VI. The principal forms represented are ellipsoid (‘sphendonoid’) and domed, and the materials used most for the weights are haematite as well as granite, basalt, marble and limestone. New research has revealed the existence of multiple weighing systems in Bronze Age Troy, a situation that was typical for mercantile centres such as Tepe Sialk, Susa or Kanes. The investigation of the Trojan balance weights and their contexts hints at the existence of Aegean and eastern Mediterranean, more precisely northern Syrian, directions of contacts.
A new dated coin of Tarkondimotos II from Anazarbos
Authors: Wright Nicholas L. 
Published: June 2012

AbstractThis short note is intended to supplement the paper ‘Anazarbos and the Tarkondimotid kings of Kilikia’ published in Anatolian Studies 58 (2008). It presents a new dated variety of a quasi-municipal bronze coin from Anazarbos minted in 19 BC – during the reign of Tarkondimotos II – and places this within the chronological framework established in the earlier publication.
Artemidi to ichnos: divine feet and hereditary priesthood in Pisidian Pogla
Authors: Petridou Georgia 
Published: June 2012

AbstractThis paper examines an unpublished dedicatory inscription to Artemis (Ephesia?), which was found in Pogla in Pisidia by S. Mitchell. The dedication seems to have accompanied a sculptured bare foot or a foot with a sandal, which has not survived. The inscription is set against a whole set of feet- and footwear-related monuments and dedicatory inscriptions from the nearby regions with special emphasis on similar dedications from Termessos. Moreover, the present paper examines the relationship between the Pogla dedication and another dedicatory monument in honour of Artemis Ephesia (in all likelihood from Cremna), which was first published and discussed by G.H.R Horsley in 1992.
The hidden material culture of the Dark Ages. Early medieval ceramics at Sagalassos (Turkey): new evidence (ca AD 650–800)
Authors: Vionis Athanasios K. , Poblome Jeroen , Waelkens Marc 
Published: June 2012

AbstractOn the basis of recent archaeological evidence unearthed in the course of systematic excavations by the Sagalassos Archaeological Research Project (Katholieke Universiteit Leuven) in southwestern Turkey, this paper attempts to pull together different strings of ceramic data in order to bridge the era between late antiquity and the Middle Ages (mid seventh century to ninth century AD). Our aim is to present samples of the ceramic assemblages excavated at the site of ancient Sagalassos from layers that are most probably dated to the late seventh and eighth centuries. An attempt has been made to examine rigorously the stratigraphy and its contents that are admittedly completely different to the known ceramic forms of the late Roman/early Byzantine (fourth century to mid seventh century) and middle Byzantine (early tenth century to mid 13th century) periods at Sagalassos. Five different pottery types are presented, both kitchenwares and tablewares. The fact that all the ware types presented here are local products should not be seen necessarily as a result of a general decline in trade, rural and/or urban life, but rather as a local response to a generally changing economic system and an emerging local pottery tradition based on household-organised production. The shift from the Roman mass-produced and customised wares (that started to disappear from the market) to non-specialised local/regional production (that started to satisfy basic household needs) need not have been a sudden one. Our ultimate aim is to contribute to recent attempts to throw more light on the archaeologically ‘hidden’ material culture of the so-called ‘Dark Ages’.
Silivri and the Thracian hinterland of Istanbul: an historic landscape
Authors: Crow Jim , Turner Sam 
Published: June 2012

AbstractHistoric Landscape Characterisation (HLC) is a method for mapping, presenting and understanding the landscape with reference to its historical development. By using high-resolution satellite imagery and archive maps we have employed Geographical Information Systems (GIS) to integrate these data with other archaeological and historical sources to create HLC-based case-studies on landscapes in the eastern Mediterranean. This article is one of two pilot studies and aims to map the landscape character in the area around Silivri west of Istanbul. HLC analysis reveals much more diversity and complexity than might be expected. The results have revealed a far greater time-depth than was anticipated with important implications for future landscape research and for regional planning.
Hittites and Arzawans: a view from western Anatolia
Authors: Mac Sweeney Naoíse 
Published: June 2012

AbstractThere has been much recent research in archaeology on the dynamics of imperial systems, and valuable work has been done on the complex relationships between the Hittite state and groups on its imperial periphery. The nature of the available source material means that these relationships are usually studied from a Hittite perspective, and that interactions with the Hittites are often seen as centrally important for these groups. In this paper, however, it is argued that archaeological evidence can be used to gain insight into alternative views – views which may not necessarily privilege relationships with the Hittites over those with other groups. One well-documented example of such a group is Arzawa, a quarrelsome coalition of principalities in western Anatolia. This paper will focus on the western Anatolian site of Beycesultan, caught between the Hittite and Arzawan heartlands. It will show that people at Beycesultan did not define themselves primarily in relation to either the Hittites or the Arzawan confederacy, but had their own dynamic and shifting world-view.
How old was the Ankara Silver Bowl when its inscriptions were added?
Authors: Durnford S.P.B. 
Published: June 2012

AbstractThe artefact known as the Ankara Silver Bowl bears two short Hieroglyphic Luwian inscriptions, each in a different ‘handwriting’. They tell us about the origin of the bowl in the year that TudhaliyalabarnaconqueredTara/i-wa/i-zi/a.Unparalleled phrasing and tantalising historical allusions make dating and interpretation problematic. The conquest mentioned is widely held to be that of Taruisa in the Troad by the 14th-century bce Hittite king Tudhaliya I/II, but epigraphy points to a Karkamiš origin for the inscriptions and probably to a post-Empire date. Treating the text as contemporary with the conquest requires either that the bowl be classed as an exceptional Empire document or that a later Tudhaliya is intended. This paper offers a new approach. It accepts a late date, offers an amended translation and proposes that the narrative be viewed as literature alluding to the past and not as contemporary chronicle. The bowl's possible status as a relic prompts questions about the transmission of history, motives for alluding to the past and the words chosen for the purpose. An interpretation of sign *273 is ventured within a speculative scenario that encompasses the bowl's various oddities.
The building complex on the Tepecik acropolis at Patara
Authors: Işın Gül 
Published: June 2012

AbstractThe ongoing excavations initiated in 2003 on the Tepecik acropolis at Patara have brought to light many noteworthy results concerning the somewhat obscure history and archaeology of Archaic Patara. The very rich pottery finds confirming the Archaic dating of the building complex are particularly important. The building complex, which was not used during the late Hellenistic, Roman or Byzantine periods, presents a good example of Archaic planning with its well-preserved foundations. In this study, the excavation work conducted on this building complex is introduced together with the associated finds.

AbstractIn 2005, during the annual ‘intensive’ archaeological survey in the peri-urban zone of Sagalassus (Pisidia, southwest Anatolia), the remains of an extensive Classical-Hellenistic settlement were identified at Düzen Tepe, 1.8km southwest of Sagalassus. The results of three seasons of site investigation (2005–2007), comprising archaeological and geophysical surveys, architectural and topographical mapping, test soundings, and archaeometric and environmental research, are presented here, together with a discussion of the settlement's most probable socio-economic background. According to the latest results of all excavated or sampled survey ceramic artefacts and AMS C14dating of faunal remains, the (proto-)urban settlement at Düzen Tepe was inhabited during the fifth to second century BC. It is the first of its kind to shed light on the material culture of the ancient inhabitants of the region, the ‘Pisidians’.
A terracotta spacer pin: evidence for a Roman baths at Amorium
Authors: Koçyiğit Oğuz 
Published: June 2012

AbstractDuring the 2008 field season at the Byzantine city of Amorium an unusual and unexpected surface find was recorded. It was a terracotta spacer pin of the type that was frequently used in Roman provincial baths. As such it provides the first evidence for the existence of a Roman-period bathhouse at Amorium, which may be regarded as a predecessor to the Byzantine bathhouse that has been excavated there.
Tools and souvenirs: the shells from Kilise Tepe (1994–1998)
Authors: Debruyne Sofie 
Published: June 2012

AbstractIn the summers of 1994–1998 a rescue excavation took place at Kilise Tepe, an archaeological site occupied from the Early Bronze Age to the Byzantine period, located in the Göksu valley in Cilicia in southern Turkey. This article analyses the shell finds from environmental and archaeological perspectives. Three categories of molluscs are identified: terrestrial, freshwater and marine. The first two are the remnants of local fauna that lived on or near the site; the marine shells came from the Mediterranean shore adjacent to the Göksu delta and the delta itself. There are indications that freshwater mussels served as tools. Marine shells were worn as ornaments.
Ring and module structures on dimension groups associated with a shift of finite type
Authors: KILLOUGH D. B. , PUTNAM I. F. 
Published: June 2012

AbstractWe study invariants for shifts of finite type obtained as the K-theory of various C*-algebras associated with them. These invariants have been studied intensively over the past thirty years since their introduction by Wolfgang Krieger. They may be given quite concrete descriptions as inductive limits of simplicially ordered free abelian groups. Shifts of finite type are special cases of Smale spaces and, in earlier work, the second author has shown that the hyperbolic structure of the dynamics in a Smale space induces natural ring and module structures on certain of these K-groups. Here, we restrict our attention to the special case of shifts of finite type and obtain explicit descriptions in terms of the inductive limits.
Effect of Cyclone Aila on estuarine fish assemblages in the Matla River of the Indian Sundarbans

Published: June 2012

Abstract:The present study examined the effect of a catastrophic cyclone (Aila) on ichthyofaunal assemblages in a tidal river of the Sundarban Delta. Sampling in six stations with a gill-net of 20-m length and 1-cm mesh size resulted in the collection of 63 species in a pre-Aila survey. Among them, 16 species were not available in the year after the cyclone. However, 12 new species were added to the assemblages in the post-Aila year during which 59 species were recorded. Analysis of Similarity (ANOSIM) confirmed significant changes in fish assemblages after the cyclone with a corresponding reduction of the species diversity and variation in the seasonal pattern of abundance. Hydrological parameters also differed with a significant surge in nutrient concentrations. Tolerance to low dissolved oxygen seemed to be a determinant factor as evident from the higher abundance of certain fishes viz. Harpadon nehereus, Liza parsia, Pampus argentius, Tenualosa ilisha and Toxotes chatareus during post-Aila year. Despite the recovery of the ichthyofaunal assemblages at the later stage of the study, a strong seasonal variation was persistent. The study therefore suggests that environmental variation in terms of increasing temperature and salinity elicit greater response in an estuarine community than temporary natural disturbances even as severe as cyclones.
Leaf-cutting ants alter seedling assemblages across second-growth stands of Brazilian Atlantic forest

Published: June 2012

Abstract:Secondary forests promote an increased abundance of leaf-cutting ants (LCA) but the consequences on forest dynamics have been poorly addressed. Here we examine seedling assemblage attributes, seed germination and seedling survival across foraging zones ofAtta cephalotescolonies inhabiting 15 second-growth patches (25–47 y old) of Atlantic forest. Seeds and seedlings were monitored within foraging zones and control sites over 1 y, including spots around ant nests. Overall, 1862 seedlings from 108 plant species were recorded. Seedling density decreased by 53% in foraging-zone plots (3.31 ± 0.23 seedlings m−2) when compared with control plots (7.02 ± 0.44 seedlings m−2) and a similar decrease was observed for species richness. Ant-induced alterations in the seedling assemblage were further indicated by segregation between foraging-zone and control plots (NMDS), habitat effects on species similarity (ANOSIM), and indicator tree species associated with control plots. While seed germination and seedling survivorship were uncorrelated to either nest distance or age of second-growth stands (with the exception ofTapirira guianensis), defoliation by LCAs was a significant cause of seedling mortality. Our results suggest that LCAs interfere with successional trajectories of Atlantic forest as foraging zones filter seedling establishment, supporting less-dense, impoverished and convergent seedling assemblages.
Insect visitation rates and foraging patterns differ in androdioecious and hermaphrodite-only populations of Laguncularia racemosa (Combretaceae) in Florida
Authors: Landry Carol L. , Rathcke Beverly J. 
Published: June 2012

Abstract:Insect-pollinated Laguncularia racemosa has a variable breeding system; some populations are androdioecious, with male and hermaphroditic plants, while others lack male plants. We observed the foraging behaviours of insects in three androdioecious and three hermaphrodite-only populations of L. racemosa in Florida. In each population, insect visitation rates were estimated from 30–108 timed intervals. We recorded the number of flowers visited by 144–224 insects during foraging bouts made to 15–40 male and hermaphroditic plants. Male plants in androdioecious populations had significantly more visitors than hermaphroditic plants, increasing the number of vectors carrying pollen from male plants. Further, many insects visited few flowers during foraging bouts, which should increase outcrossing frequency. According to mathematical models, male plants benefit from these combined factors. Plants in hermaphrodite-only populations had significantly more visitors than hermaphroditic plants in androdioecious populations. Proportionately more insects visited many flowers during foraging bouts in hermaphrodite-only versus androdioecious populations. The increased likelihood of geitonogamous self-pollination could help explain the lack of male plants in hermaphrodite-only populations. Differences in pollinator assemblages and the relative abundances of several species were responsible for differences in foraging behaviours: Apis mellifera, Bombus sp., Melissodes sp., Xylocopa sp., Euodynerus sp. and a calliphorid species.
Diet and habitat-niche relationships within an assemblage of large herbivores in a seasonal tropical forest

Published: June 2012

Abstract:There is little understanding of how large mammalian herbivores in Asia partition habitat and forage resources, and vary their diet and habitat selection seasonally in order to coexist. We studied an assemblage of four large herbivores, chital (Axis axis), sambar (Cervus unicolor), gaur (Bos gaurus) and Asian elephant (Elephas maximus), in the seasonal tropical forests of Bandipur and Mudumalai, South India, and tested predictions regarding the species’ seasonal diet browse : graze ratios, habitat selection and habitat-niche preference and overlap. Field data collected for the study included the seasonal variation in grass quality, the seasonal variation in δ13C in the species’ faeces and the seasonal variation in the species’ habitat selection and overlap using a grid-based survey. Results of the δ13C analyses showed that the chital was more of a grazer in the wet season (−17.9‰ to −21.6‰), but that it increased the proportion of browse in its diet in the dry season (−25.6‰ to −27.7‰); the gaur was a grazer for most of the year (−15.3‰ to −18.6‰); the sambar preferred to browse throughout the year (−21.1‰ to −30.4‰); and that the elephant was a mixed feeder (−14.2‰ to −21.4‰). Elephant habitat-niche breadth was high (0.53 in wet and 0.54 in dry) and overlapped equally with that of the other species in both seasons (0.39–0.94). The gaur had the most restricted habitat-niche breadth in both seasons (0.25 in wet and 0.28 in dry), and it switched from the moist deciduous habitat in the dry season to the dry deciduous habitat in the wet season. These results offer the first insights into the seasonal variation in browse : graze diet ratios and the habitat-niche overlap amongst the common largest-bodied mammalian herbivore species found in South India.
Differential growth responses in seedlings of ten species of Dipterocarpaceae to experimental shading and defoliation

Published: June 2012

Abstract:The responses of plants to shade and foliar herbivory jointly affect growth rates and community assembly. We grew 600 seedlings of ten species of the economically important Dipterocarpaceae in experimental gradients of shading (0.3–47.0% of full sunlight) and defoliation (0, 25%, 50% or 75% of leaf area removed). We assessed stem diameters initially, after 2 and 4 mo, and calculated relative growth rates (RGR) with a linear model. Shading interacted with defoliation, reducing RGR by 21.6% in shaded conditions and 8.9% in well-lit conditions. We tested three hypotheses for interspecific trade-offs in growth responses to shading and defoliation. They could be positively related, because both reduce a plant's access to carbon, or inversely related because of trade-offs between herbivore resistance and tolerance. We observed, however, that species varied in their response to shading, but not defoliation, precluding an interspecific trade-off and suggesting that plants tolerate shade and herbivory with differing strategies. Shading most strongly reduced the growth of species with less-dense wood and larger seeds. The strong and variable growth responses to shade, contrasted with the weak and uniform responses to defoliation, suggest that variation in light availability more strongly affects the growth of tropical tree seedlings, and thus community assembly, than does variation in herbivory.
