Preventing Proximal Femur Pathologic Fractures Improves Outcomes in Patients wi...
Páscoa Pinheiro, Joana; Nabais, Mariana; Spranger , André; Almeida, Paulo; Portela, José; Soares do Brito, JoaquimINTRODUCTION: Metastatic bone disease decreases a patient’s function and increases morbidity being frequently found in patients with solid malignant tumors and multiple myeloma (MM). The effective treatment of these patients demands a multidisciplinary team approach to prevent catastrophic events such as pathologic fractures, especially in the proximal femur. This study aimed to evaluate oncologic outcomes, sur...
The exploitation of crabs by Last Interglacial Iberian Neanderthals: the eviden...
Nabais, Mariana; Dupont, Catherine; Zilhão, JoãoHominin consumption of small prey has been much discussed over the past decades. Such resources are often considered to be unproductive in the Middle Paleolithic due to their limited meat yield and, hence, low energy return. However, ethnographic studies suggest that small prey—including shellfish—are a reliable, predictable and by no means marginal resource, and there is increasing evidence for their inclusion...
Formation processes, fire use, and patterns of human occupation across the Midd...
Angelucci, Diego E.; Nabais, Mariana; Zilhão, JoãoGruta da Oliveira features a c. 13 m-thick infilling that includes a c. 6.5 m-thick archaeological deposit (the “Middle Palaeolithic sequence” complex), which Bayesian modelling of available dating results places in MIS 5a (layers 7–14) and MIS 5b (layers 15–25), c. 71,000–93,000 years ago. The accumulation primarily consists of sediment washed in from the slope through gravitational processes and surface dynam...
Late Quaternary (MIS 5a-5b) climate and environments of western Iberia inferred...
López-García, Juan; Fagoaga, Ana; Nabais, Mariana; Póvoas, Liliana; Zilhão, JoãoMarine Isotope Stage 5 (MIS 5) is well represented in palynological studies of North Atlantic marine cores but in only a handful of archeological sequences from the adjacent Iberian landmass. In this paper, we undertake a multi-proxy analysis of small mammal assemblages (insectivores, bats, and rodents) from a 6 m-thick succession, dated to MIS 5a-5b (Layers 7–22), situated in the southeastern edge of the Centr...
Palaeogenomic analysis of black rat (Rattus rattus) reveals multiple european i...
Yu, He; Jamieson, Alexandra; Hulme-Beaman, Ardern; Conroy, Chris J.; Knight, Becky; Speller, Camilla; Al-Jarah, Hiba; Eager, Heidi; Trinks, AlexandraThe distribution of the black rat (Rattus rattus) has been heavily influenced by its association with humans. The dispersal history of this non-native commensal rodent across Europe, however, remains poorly understood, and different introductions may have occurred during the Roman and medieval periods. Here, in order to reconstruct the population history of European black rats, we first generate a de novo genom...
Brief overview of zooarchaeological research within the framework of Middle Pal...
Nabais, MarianaIn the course of a general review of zooarchaeological studies, particular attention is given to the development of the thinking process associated with hominin dietary strategies. Since the dawn of archaeological studies animal bones were noticed and recovered in association with man‑made tools. Since then, faunal remains have been discussed as the result of human dietary practices. However, the way such feedi...
A Espada do Monte das Oliveiras (Serpa) – uma arma do Bronze Pleno do Sudoeste
Soares, Rui; Valério, Pedro; Nabais, Mariana; Soares, António M. MongeNesta comunicação dá-se a conhecer uma espada, atribuível ao Bronze Pleno do Sudoeste, encontrada há vários anos em trabalhos agrícolas próximo da cidade de Serpa. A espada foi encontrada aparentemente descontextualizada, posteriormente limpa de produtos de corrosão e guardada pelo achador que, amavelmente, nos permitiu o seu estudo. A espada teria cerca de 50 cm de comprimento e o seu encabamento era efectuado...
Last Interglacial Iberian Neandertals as fisher-hunter-gatherers
Zilhão, João; Angelucci, Diego E.; Igreja, Marina; Arnold, L. J.; Badal García, Ernestina; Callapez, Pedro M.; Cardoso, João Luis; d’Errico, F.The origins of marine resource consumption by humans have been much debated. Zilhão et al. present evidence that, in Atlantic Iberia's coastal settings, Middle Paleolithic Neanderthals exploited marine resources at a scale on par with the modern human–associated Middle Stone Age of southern Africa (see the Perspective by Will). Excavations at the Figueira Brava site on Portugal's Atlantic coast reveal shell mid...
The consumption of tortoise among Last Interglacial Iberian Neanderthals
Nabais, Mariana; Zilhão, JoãoOptimal foraging theory and diet breadth models often place large mammals in top-ranking positions due to their high-energy return. However, mass collection of small prey can result in comparable return rates, and dietary diversity is nutritionally beneficial on its own right. A growing body of evidence recovered from several sites in the Mediterranean Basin confirms Neanderthal use of small size prey. Slow-mov...
Chelonian use in Portugal: Evidence from Castelo Velho de Safara
Nabais, Mariana; Boneta, Iratxe; Soares, RuiChelonian remains in Portuguese archaeological sites are relatively common, but they frequently occur in low abundance within zooarchaeological assemblages. Turtle and tortoise remains appear in Palaeolithic contexts through Modern times. However, there is a clear lack of representation of these reptiles within Bronze Age, Iron Age and Roman contexts. Castelo Velho de Safara is now the first Portuguese site sho...
