Standardization in the Pre-Columbian Pottery from El Caño, Panama: Specialization, Productivity and Consumption

The pottery found in the burials of El Cano is uniform in style to these made in the coclesanos valleys between 700 and 1000 AD. The coefficient of variability of the different pottery forms, evidence diverse standardizations values for polychrome and non-polychrome ceramics. Moreover, data of funerary contexts from the Cano recently excavated, suggest that elite has controlled ceramic production. This control over the production of certain goods reveals that these were important in the support or proper operational of the chiefdoms in Panama and mark the phase of splendour of this culture.

A Review of the Dodo and its Ecosystem: Insights from a Vertebrate Concentration Lagerstätte in Mauritius

The dodo Raphus cucullatus Linnaeus, 1758, an extinct and flightless, giant pigeon endemic to Mauritius, has fascinated people since its discovery, yet has remained surprisingly poorly known. Until the mid-19th century, almost all that was known about the dodo was based on illustrations and written accounts by 17th century mariners, often of questionable accuracy. Furthermore, only a few fragmentary remains of dodos collected prior to the bird’s extinction exist. Our understanding of the dodo’s anatomy was substantially enhanced by the discovery in 1865 of subfossil bones in a marsh called the Mare aux Songes, situated in southeastern Mauritius. However, no contextual information was recorded during early excavation efforts, and the majority of excavated material comprised larger dodo bones, almost all of which were unassociated. Here we present a modern interdisciplinary analysis of the Mare aux Songes, a 4200-year-old multitaxic vertebrate concentration Lagerst€atte. Our analysis of the deposits at this site provides the first detailed overview of the ecosystem inhabited by the dodo. The interplay of climatic and geological conditions led to the exceptional preservation of the animal and associated plant remains at the Mare aux Songes and provides a window into the past ecosystem of Mauritius. This interdisciplinary research approach provides an ecological framework for the dodo, complementing insights on its anatomy derived from the only associated dodo skeletons known, both of which were collected by Etienne Thirioux and are the primary subject of this memoir.

Settlement Duration and Materiality:Formal Chronological Models for the Development of Barnhouse, a Grooved Ware Settlement in Orkney

Radiocarbon dating and Bayesian chronological modelling, undertaken as part of the investigation by the Times of Their Lives project into the development of Late Neolithic settlement and pottery in Orkney, has provided precise new dating for the Grooved Ware settlement of Barnhouse, excavated in 1985–91. Previous understandings of the site and its pottery are presented. A Bayesian model based on 70 measurements on 62 samples (of which 50 samples are thought to date accurately the deposits from which they were recovered) suggests that the settlement probably began in the later 32nd century cal bc (with Houses 2, 9, 3 and perhaps 5a), possibly as a planned foundation. Structure 8 – a large, monumental structure that differs in character from the houses – was probably built just after the turn of the millennium. Varied house durations and replacements are estimated. House 2 went out of use before the end of the settlement, and Structure 8 was probably the last element to be abandoned, probably during the earlier 29th century cal bc. The Grooved Ware pottery from the site is characterised by small, medium-sized, and large vessels with incised and impressed decoration, including a distinctive, false-relief, wavy-line cordon motif. A considerable degree of consistency is apparent in many aspects of ceramic design and manufacture over the use-life of the settlement, the principal change being the appearance, from c. 3025–2975 cal bc, of large coarse ware vessels with uneven surfaces and thick applied cordons, and of the use of applied dimpled circular pellets. The circumstances of new foundation of settlement in the western part of Mainland are discussed, as well as the maintenance and character of the site. The pottery from the site is among the earliest Grooved Ware so far dated. Its wider connections are noted, as well as the significant implications for our understanding of the timing and circumstances of the emergence of Grooved Ware, and the role of material culture in social strategies.

Why are egg fertilization rates not correlated with hatching success in sea turtles?

[EN] The relative number of developing eggs is directly affected by fertilization rate, and unfertile eggs may indirectly negatively affect development of viable eggs within the nest. Thus, the number of viable eggs at laying should influence hatching success. We have studied both parameters in a nesting population of loggerhead turtles from Boavista Island (Republic of Cabo Verde). Fertility was estimated based on eggs excavated from nests within the first 96 hours after deposition. Our results confirm a high egg fertilization rate for the species, which exceeded an average of 94% fertility (95% confidence limits: 91.9 and 96.2%, N=43 nests).

Évaluation de la performance des drains et des matériaux filtrants à ralentir le colmatage et l’ensablement en sol sableux et ferreux

Au Québec, les drains installés dans les sols sableux-limoneux sont sensibles au colmatage par ensablement et/ou par ocre de fer. Dans le passé, les drains avec des pertuis inférieurs à 2 mm étaient utilisés au Québec avec un filtre tissé de 110 microns ou un filtre tricoté de 450 microns. Récemment, des drains avec des pertuis supérieurs à 2 mm ainsi qu’un filtre de 250 microns ont été introduits sur le marché mais n’ont jamais été testés. Le projet avait pour objectif de déterminer les vitesses auxquelles se feront l’ensablement et le colmatage ferrique pour différentes combinaisons de drains (pertuis de 1,8 mm et de 3 mm) et de filtres (110 μm, 250 μm et 450 μm) dans un sol sableux à Bécancour. Un dispositif expérimental en blocs complets (3) aléatoires a été utilisé. Les débits ont été mesurés à la sortie des drains de chaque parcelle et les hauteurs des nappes ont été mesurées avec un bulleur dans des puits d’observation. Le suivi du pH, du potentiel d’oxydoréduction et du contenu en Fe2+ a été réalisé dans l’eau de la nappe et celle des drains. Les drains excavés 13 mois après leur installation ne montrent que des traces de sédiments et de colmatage ferrique. Les niveaux de Fe2+ sont significativement plus faibles dans l’eau à la sortie des drains que dans l’eau de la nappe. Le processus de colmatage ferrique ne semble que commencer et son impact n’est pas mesurable au niveau des débits unitaires à la sortie des drains.

Preliminary Notes on Two Seasons of Research at Oplontis B (2014-2015)

The complex known as Oplontis B lies in the shadow of Vesuvius, about 3 kilometers west of Pompeii and 300 meters from the well-known Villa A. Since its first excavation and reconstruction in the 1970s and 1980s, Oplontis B has languished in abandonment ―virtually unstudied. The Oplontis Project, led by John Clarke and Michael Thomas, began investigating the site in 2012 after completing its work on Villa A. The documentation of the complex is a primary task. In the past few years members of the Project team have cataloged the previously excavated materials, recording over 1200 wine amphorae as well as a variety of other artifacts. At the same time, Marcus Abbott has laser-scanned the building to produce a detailed plan of the site. The excavations have similar aims: to record the 79 CE level of the complex and to investigate its development. This paper discusses the preliminary results of the last two seasons of excavations and cataloging efforts which build on our previous work conducted in 2012 and 2013.

Scavo 2015 della necropoli romana di Porta Nocera a Pompei: nascita e sviluppo di un paesaggio funerario romano (I sec. a.C. - I sec. d.C.)

The Porta Nocera 2 program aims to study the process of establishing and developing a Roman urban necropolis from a road network, which is an essential setting in the expression of death in the Roman time. As such, the necropolis of Porta Nocera essentially excavated between 1952 and 1958 and then in 1983 offers a privileged field study. Indeed, monuments and funerary enclosures with burial structures (graves, cremation areas) built along the road to Nocera are well preserved and allow to observe funerary practices on a relatively short time, about 160 years, since we can assume that the necropolis has been founded with the colony in 80 BC. It is then the necessity to organize a burial area according to Roman customs, which is at the origin a new landscape development until then essentially marked by the presence of the urban wall.

Preliminary Report on the 2014 Field Season of the American Excavations at Morgantina: Contrada Agnese Project (CAP)

This article provides a preliminary report on the 2014 excavations carried out by the American Excavations at Morgantina (Sicily): Contrada Agnese Project (CAP). The 2014 season was the second year of this multiyear research and excavation project aimed at investigating both the urban planning of the city and the lives of its residents, with a specific focus on the periods of occupation and cultural transformation from the third to first century BCE. During the second season, three trenches were excavated in the area corresponding to Lot One of the urban insula W13/14S. This preliminary report presents the significant stratigraphic units and material finds encountered in each trench, along with a provisional outline of the phases of activity, setting the developments observed in each trench within the broader historical and archaeological context of the urban center at Morgantina. The discovery of several rooms with similar architectural features suggests that they belong to a single building, the so-called Southeast Building, the function and dimensions of which will be investigated in future CAP excavations.

La lunga diacronia di un sito archeologico toscano: il complesso di Pava (Siena) dal II al XIII sec. d.C.

The paper is centred on southern Tuscany on the archaeological complex of Pieve di Pava where archaeological research have been conducted since the 2000 by the University of Siena. The parish church is first mentioned as the baptisterium Sancti Petri in Pava in a document of AD 715 part of a long dispute between the bishop of Siena and the bishop of Arezzo. But the archaeological excavation revealed a longer history of the site that start from the Roman period with a villa dated between the second to the fourth century BC. The villa continued to grow in Late Antiquity since it was transformed by a church. The paper is centred on these fluctuations of the site and on the implications of the transformations on the landscape. One of the stronger element of the Pava site, in addition to the very particular plan of the early church (built with two opposing apses) was the huge cemetery around the church that was used from the seventh century BC until the Middle Ages. The 900 excavated graves make this one of the largest and most long-lasting late-Roman to medieval cemeteries excavated in Europe.

Contributo para o conhecimento do povoamento rural romano no concelho de Montemor-o-Novo: caso da barragem dos minutos

O concelho de Montemor-o-Novo é rico em vestígios arqueológicos de várias cronologias, pelo que a época romana não é excepção. Durante muito tempo pouco se conhecia deste período cronológico, particularmente a forma do seu povoamento. Durante os anos 60 do século XX, foram identificadas e escavadas algumas estruturas deste período, nomeadamente a Fonte do Prior, o Curral dos Cães e o Cabeço do Ceivo. No entanto, foi durante as obras da Barragem dos Minutos que começamos a ter uma nova perceção de como seria o povoamento romano neste território. Sítios como estes têm vindo, ao longo do tempo, a ser colocados de parte quando se falava sobre a romanização dos campos por se considerar que essa ocupação era exclusiva das luxuosas villae e por se pensar que estes sítios fariam parte das villae. Neste trabalho iremos ver o resultado das intervenções realizados na Barragem dos Minutos, bem como as realizadas no regolfo da Barragem de Alqueva com o objectivo de tentar perceber estas novas realidades do povoamento romano; Abstract: The Montemor-o-Novo municipality is rich in archaeological remains of various chronologies, so the Roman era is no exception. But for a long time little was known of this chronological period and especially the shape of your settlement. During the 60s of the twentieth century, they have been identified and excavated some structures of this period, namely the Fonte do Prior, the Curral dos Cães and the Cabeço Ceivo. But it was during the construction of the dam of Minutos we started to have a new perception of how would the Roman settlement in this territory. Sites like these have been, over time, to be put aside when talking about the romanization of the fields in Roman times as it was considered that this occupation was exclusive of villae luxurious and think that these sites would be part of the villae. In this work we will see the result of the work done at the dam of the Minutos, as well as the work carried out in the surroundings of the Alqueva Dam and try to understand these new realities of the Roman settlement.

SEDIMENT BIOTURBATION POTENTIAL of UCA RAPAX and UCA URUGUAYENSIS AS A RESULT of THEIR FEEDING ACTIVITY

Bioturbation of mangrove sediments by Uca uruguayensis (Nobili, 1901) and U. rapax (Smith, 1870) was compared based on the grain-size composition and organic content in surface sediment around the burrow and feeding pellets in two mangrove zones of the Sao Vicente Estuary, state of São Paulo, Brazil. For each species, 25 burrows with active crabs were selected. All pellets within a 15-cm radius of each burrow were carefully collected; samples of substrate were taken; and the crab occupant was excavated, sexed, and measured for carapace width (CW). The number of spoon-tipped setae on the second maxilliped of each species was estimated; U. uruguayensis showed more of these setae than U. rapax. For both species, the sediment post-processed by feeding activity (feeding pellets) showed a similar increase of coarser fractions and a smaller organic content. However. U. uruguayensis was more efficient in removing organic matter (88.1%) from the sediment than U. rapax (37.5%). These results suggest that different numbers of spoon-tipped setae on the second maxillipeds of the fiddler crabs do not affect the potential for grain-size selection, but result in differing abilities to remove organic matter from the sediment.

Root behavior of savanna species in Brazil's Pantanal wetland.

The objective of this study was to determine the maximum depth, structure, diameter and biomass of the roots of common woody species in two savanna physiognomies (savanna woodland and open woody savanna) in Brazil's Pantanal wetland. The root systems of 37 trees and 34 shrubs of 15 savanna species were excavated to measure their length and depth and estimate the total root biomass through allometric relationships with stem diameter at ground level. In general, statistical regression models between root weight and stem diameter at ground level showed a significance of P < 0.05 and R2 values close to or above 0.8. The average depths of the root system in wetland savanna woodland and open woody savanna are 0.8 ± 0.3 m and 0.7 ± 0.2 m, respectively, and differ from the root systems of savanna woody species in non-flooding areas, whose depth usually ranges from 3 to 19 m.Weattribute this difference to the adaptation of woody plant to the shallow water table, particularly during the wet season. This singularity of woody species in wetland savannas is important when considering biomass and carbon stocks for national and global carbon inventories.

The Architecture of the Persian Period in the Levant

The earliest scholars were not concerned about preparing extensive investigations linking the Persian-period building remains excavated in the entire Levant together. Moreover, the research interests of scholars caused some impediments to the study of this period viz in the last decades; the Achaemenid period has been neglected by the scholars who -in turn- focused on the earlier and later periods for religious reasons. Too, while some regions have been studied abundantly, but it was not the case in other areas, which makes our knowledge is incomplete. From the explanation side, some scholars try to interpret the architectural remains from an ethnic perspective or unsubstantiated personal fancies, so their arguments were utterly lacking any objectivity. This thesis explores what are the Persian architectural and ornamental impacts on the Levantine architecture and the relations between Persian-period sites in Syria-Palestine region. Too, the architectural remains and their contents benefited us to clarify the settlement patterns in the regions being discussed. The author analyzed the ground plans of the buildings and their architectural features and ornamental motifs by conducting a descriptive, analytical, and interpretative study. He also conducted comparisons with similar buildings outside the Levant, especially in Fars to obtain a more comprehensive and systematic study, and then extracting any direct or indirect Persian influences. This has given us a better understanding of the nature of the social, political, and religious life in the entire Levant and the knowledge gap has been bridged to a satisfying extent. This study has demonstrated a few of the Achaemenid impacts, especially on the northern coastline of the Levant.
