Genome-wide association study identifies genetic variants underlying footrot in...
Gaspar, Daniel; Ginja, Catarina; Carolino, Nuno; Leão, Célia; Monteiro, Helena; Tábuas, Lino; Branco, Sandra; Padre, Ludovina; Caetano, PedroOvine footrot caused by Dichelobacter nodosus (D. nodosus) is a contagious disease with serious economic and welfare impacts in sheep production systems worldwide. A better understanding of the host genetic architecture regarding footrot resistance/susceptibility is crucial to develop disease control strategies that efficiently reduce infection and its severity. A genome-wide association study was performed usi...

Gaspar, Daniel; Ginja, Catarina; Carolino, Nuno; Leão, Célia; Monteiro, Helena; Tábuas, Lino; Branco, Sandra; Padre, Ludovina; Caetano, PedroThis is the first attempt to identify molecular markers associated with footrot in Portuguese Merino sheep. These findings provide relevant information on a likely genetic association underlying footrot resistance/susceptibility and the potential candidate genes affecting this trait. Genetic selection strategies assisted on the information obtained from this study could enhance Merino sheep-breeding programs, i...
Iron age genomic data from Althiburos – Tunisia renew the debate on the origins...
Ginja, Catarina; Guimarães, Silvia; da Fonseca, Rute R.; Rasteiro, Rita; Rodríguez-Varela, Ricardo; Simões, Luciana G.; Sarmento, CindyThe Maghreb is a key region for understanding the dynamics of cattle dispersal and admixture with local aurochs following their earliest domestication in the Fertile Crescent more than 10,000 years ago. Here, we present data on autosomal genomes and mitogenomes obtained for four archaeological specimens of Iron Age (∼2,800 cal BP–2,000 cal BP) domestic cattle from the Eastern Maghreb, i.e. Althiburos (El Kef, T...
The facial reconstruction of a Mesolithic Dog, Muge, Portugal
Moraes, Cicero; Pereira, Hugo Matos; Requicha, Joao Filipe; Alves, Lara; Alexandre-Pires, Graça; Jesus, Sandra de; Guimarães, Silvia; Ginja, CatarinaABSTRACT: This paper presents the facial reconstruction of a Mesolithic dog whose skeleton was recovered from the Muge shell middens (Portugal) in the 19th century. We used the anatomical deformation approach based on a collection of computer tomography images as an attempt to reconstruct the Muge dog's head appearance. We faced a few challenges due to the level of bone displacement and the absence of some cran...
Origin & evolution of Iberian dogs
Pires, Ana Elisabete; Ginja, CatarinaThe dog (Canis lupus familiaris) was the first species to be domesticated from the wolf. Since its domestication, it has undergone thousands of years of selective breeding, contributing to a myriad of phenotypic/behaviour variants. Most modern dog breeds are 200 years old and are of European ancestry. In Iberia, there are 21 internationally recognized dog breeds, including local varieties within breeds. In this...
A multidisciplinary study of Iberian Chalcolithic dogs
Blaschikoff, Ludmilla; Daza-Perea, Arantxa; Requicha, João; Detry, Cleia; Rasteiro, Rita; Guimarães, Sílvia; Ureña, Irene; Serra, Octávio; Schmidt, RyanDomesticated dogs have been present in the Iberian Peninsula long before other domesticated species, back to the late Palaeolithic period. Their origin is still uncertain, but dogs were already well established during the Chalcolithic period (ca. 5000–4000 BP). This study employed a multidisciplinary approach comprising osteometric, radiographic and palaeogenomic analyses to characterize Chalcolithic Iberian Ca...

The potential of computed tomography in odontometry: application to a Mesolithi...
Pereira, Hugo Matos; Requicha, João Filipe; Alves, Lara; Gonçalves, David; Correia, Joana Belo; Alexandre-Pires, Graça; de Jesus, Sandra; Viegas, CarlosA large odontometric reference database is essential for a clear and reliable differentiation between the teeth of dogs and wolves found in archaeological contexts. However, the data compilation of skeletal material is a slow process because access to dog remains may be difficult. The expansion of a dental database could benefit from computed tomography (CT) scans performed on live dogs during medical appointme...
