- Southern Portugal animal exploitation systems: trends and changes from Neolithic to Bronze Age. A follow-up overviewPublication . Valente, Maria João; Carvalho, AntónioZooarchaeological studies in Neolithic, Chalcolithic and Early Bronze Age Portugal have witnessed important developments in recent years, even if still largely based on taxonomic analyses. Other approaches depend heavily on the abundance and preservation conditions of faunal collections, which are often inadequate
- Your horse is a donkey! Identifying domesticated equids from Western Iberia using collagen fingerprintingPublication . Paladugu, Roshan; Richter, Kristine Korzow; Valente, Maria João; Gabriel, Sónia; Detry, Cleia; Warinner, Christina; Dias, Cristina BarrocasSkeletal remains of two equid species, Equus caballus (horse) and Equus asinus (donkey), have been found in archaeological contexts throughout Iberia since the Palaeolithic and Chalcolithic periods, respectively. These two species play different economic and cultural roles, and therefore it is important to be able to distinguish between the two species to better understand their relative importance in the past human societies. The most reliable morphological features for distinguishing between the two domesticated equids are based on cranial measure-ments and tooth enamel folds, leading to only a small percentage of archaeological remains that can be identified to species. Ancient DNA (aDNA) analysis can be used to reliably distinguish the two equids, but it can be cost prohibitive to apply to large assemblages, and aDNA preservation of non-cranial elements is often low. Collagen peptide mass fingerprinting by matrix-assisted laser desorption time-of-flight (MALDI-TOF) mass spectrometry, also known as zooarchaeology by mass spectrometry (ZooMS), is a minimally destructive and cost-effective alternative to aDNA analysis for taxonomic determination. However, current ZooMS markers lack resolution below the genus level Equus. In this paper, we report a novel ZooMS peptide marker that reliably distinguishes between horses and donkeys using the enzyme chymotrypsin. We apply this peptide marker to taxonomically identify bones from the Iberian Peninsula ranging from the Iron Age to the Late Modern Period. The peptide biomarker has the potential to facilitate the collection of morphological data for zooarchaeological studies of equids in Iberia and throughout Eurasia and Africa.
- Editorial / ApresentaçãoPublication . Oliveira, António Paulo; Valente, Maria João; Araujo, RenataO número 12 da revista promontoria é dedicado ao Algarve rural. Este constitui um tema que não é, no presente, fácil de delimitar, em especial, quando é considerado na sua expressão mais abrangente, conferindo especial relevância às atividades e às comunidades. Como a geografia ou o urbanismo não se têm cansado de enunciar, os limites entre o campo e a cidade tornaram-se gradualmente mais difusos. A contraposição tende cada vez mais a ser outra; entre as ‘regiões urbanas’ do litoral e os ‘territórios vagos’ do interior. É o que ocorre também no Algarve, sempre mais exposto à desertificação das áreas serranas, depois de restringido, durante décadas, aos discursos em torno à profunda transformação da orla costeira.
- Beyond faith: Biomolecular evidence for changing urban economies in multi‐faith medieval PortugalPublication . Toso, Alice; Schifano, Simona; Oxborough, Charlotte; McGrath, Krista; Spindler, Luke; Castro, Anabela; Evangelista, Lucy; Filipe, Vanessa; Gonçalves, Maria João; Marques, Antonio; Mendes da Silva, Inês; Santos, Raquel; Valente, Maria João; McCleery, Iona; Alexander, MichelleDuring the Middle Ages, Portugal witnessed unprecedented socioeconomic and religious changes under transitioning religious political rule. The implications of changing ruling powers for urban food systems and individual diets in medieval Portugal is poorly understood. This study aimed to elucidate the dietary impact of the Islamic and Christian conquests.
- The genomic history and global expansion of domestic donkeysPublication . Todd, Evelyn T.; Tonasso-Calvière, Laure; Chauvey, Loreleï; Schiavinato, Stéphanie; Fages, Antoine; Seguin-Orlando, Andaine; Clavel, Pierre; Khan, Naveed; Pérez Pardal, Lucía; Patterson Rosa, Laura; Librado, Pablo; Ringbauer, Harald; Verdugo, Marta; Southon, John; Aury, Jean-Marc; Perdereau, Aude; Vila, Emmanuelle; Marzullo, Matilde; Prato, Ornella; Tecchiati, Umberto; Bagnasco Gianni, Giovanna; Tagliacozzo, Antonio; Tinè, Vincenzo; Alhaique, Francesca; Luis Cardoso, João; Valente, Maria João; Telles Antunes, Miguel; Frantz, Laurent; Shapiro, Beth; Bradley, Daniel G.; Boulbes, Nicolas; Gardeisen, Armelle; Horwitz, Liora Kolska; Öztan, Aliye; Arbuckle, Benjamin S.; Onar, Vedat; Clavel, Benoît; Lepetz, Sébastien; Vahdati, Ali Akbar; Davoudi, Hossein; Mohaseb, Azadeh; Mashkour, Marjan; Bouchez, Olivier; Donnadieu, Cécile; Wincker, Patrick; Brooks, Samantha A.; Beja-Pereira, Albano; Wu, Dong-Dong; Orlando, LudovicDonkeys transformed human history as essential beasts of burden for long-distance movement, especially across semi-arid and upland environments. They remain insufficiently studied despite globally expanding and providing key support to low- to middle-income communities. To elucidate their domestication history, we constructed a comprehensive genome panel of 207 modern and 31 ancient donkeys, as well as 15 wild equids. We found a strong phylogeographic structure in modern donkeys that supports a single domestication in Africa similar to 5000 BCE, followed by further expansions in this continent and Eurasia and ultimately returning to Africa. We uncover a previously unknown genetic lineage in the Levant similar to 200 BCE, which contributed increasing ancestry toward Asia. Donkey management involved inbreeding and the production of giant bloodlines at a time when mules were essential to the Roman economy and military.
