Food web attributes to assess spatial-temporal dynamics in estuarine benthic ec...
Vieira, Soraia; Maurer, Anne-France; Dias, Cristina; Adão, Helena; Sroczynska, KasiaThreatened benthic ecosystems need urgent tools for effective bioassessment and relevant management. EU Marine Strategy Framework Directive (MSFD) obligates member states to achieve GES (Good Environmental Status) for 11 descriptors of environmental state (MSFD; 2008/56/EC). From all of the descriptors, D4 that focuses on Food Webs is the most functional-oriented indicator, but also the most challenging to impl...
A Arqueometria na Bioarqueologia: dieta, saúde e mobilidade no passado
Curto, Ana; Coradeschi, Ginevra; Maurer, Anne-France; Navarrete, VanessaA Arqueometria integrada nos estudos bioarqueológicos inclui métodos físicos e químicos para o estudo de remanescentes humanos, animais e botânicos em contextos arqueológicos. Esta abordagem multidisciplinar permite uma compreensão mais profunda de aspectos como saúde, dieta, estatuto social e padrões de migração de populações antigas. Este artigo apresenta os métodos e técnicas mais comuns em Arqueometria para...
Estratégias alimentares dos animais domésticos do povoado de Leceia (Oeiras, Po...
Navarrete, Vanessa; Cardoso, JL; Dias, CB; Detry, C; Curto, Ana; Waterman, AJ; Wright, E; Maurer, Anne-FranceIn this article, we analyse faunal samples from the Late Neolithic (Layer 4) and Early Chalcolithic (Layer 3) levels of the fortified settlement of Leceia (Oeiras, Portugal) in order to understand the management of the feeding of domestic animals recovered in these excavations. Through the analyses of stable isotopes of δ13C and δ15N in bone collagen, we aim to characterise the grazing systems and the maintenan...

Insights into agricultural practices at the Phoenician site of Castro Marim bet...
Paladugu, Roshan; Celant, Alessandra; Jha, Gopesh; Di Rita, Federico; de Sousa, Elisa; Arruda, Ana Margarida; Maurer, Anne-France; Magri, DonatellaCastro Marim is an Iron Age site from the Algarve region, Portugal. The earliest evidence of settlement, from the Late Bronze Age, dates to the 9th century BCE, with the Phoenician-Punic period dating from the 7th to the 3rd century BCE. This study focuses on the stable isotope analysis of plant and collagen of faunal remains to reconstruct cultivation and husbandry practices. Barley was the most abundantly cul...
Optimized in-solution enrichment over a million ancient human SNPs
Davidson, Roberta; Roca-Rada, Xavier; Ravinshakar, Shyamsundar; Taufik, Leonard; Haarkötter, Christian; Collen, Evelyn; Williams, Matthew P.Background In-solution hybridization enrichment of genetic markers is a method of choice in paleogenomic studies, where the DNA of interest is generally heavily fragmented and contaminated with environmental DNA, and where the retrieval of genetic data comparable between individuals is challenging. Here, we benchmark the commercial “Twist Ancient DNA” reagent from Twist Biosciences using sequencing libraries fr...
The genetic history of Portugal over the past 5.000 years
Roca-Rada, Xavier; Davidson, Roberta; Williams, Mathew P.; Villalba Mouco, Vanessa; Carvalho, António faustino; Ravinshakar, Shyamsundar; Collin, EvelynBackground Recent ancient DNA studies uncovering large-scale demographic events in Iberia have presented very limited data for Portugal, a country located at the westernmost edge of continental Eurasia. Here, we present the most comprehensive collection of Portuguese ancient genome-wide data, from 67 individuals spanning 5000 years of human history, from the Neolithic to the nineteenth century. Results We ident...
Shrouded in history: Unveiling the ways of life of an early Muslim population i...
MacRoberts, Rebecca A,; Liberato, M.; Roca-Roda, Xavier; Valente, Maria João; Relvado, Cláudia; Matos Fernandes, Teresa; Barrocas Dias, CristinaIn around 716 AD, the city of Santarém, Portugal, was conquered by the Berber and Arab armies that swept the Iberian Peninsula and went on to rule the region until the 12th century. Archaeological excavations in 2007/08 discovered an Islamic necropolis (Avenida 5 de Outubro #2–8) that appears to contain the remains of an early Muslim population in Santarém (8th– 10th century). In this study, skeletal material f...
Physical Impairment and Care Estimation in Medieval Estremoz (Portugal): A Bioa...
Curto, Ana; Lopes, Célia; Maurer, Anne-France; Fernandes, TeresaThis study aims to compare diet and skeletal health indicators between individuals with varying degrees of physical impairment and the general adult population from medieval Estremoz, Portugal, to assess their health status and their survival outcomes. Skeletal remains from 41 male adult individuals, including 8 with physical impairments and 33 from the general population, were analyzed. The impairment of these...
