Landim pigs, a population of native pigs from Mozambique are currently threatened by the recent introduction of European exotic breeds. Like most African pig populations, Landim pigs have never been characterized at the genome level and are well adapted to harsh conditions which include adaptation to endemic diseases. In this study, we provide a comprehensive genetic characterization of Landim pigs using whole-...


Genetic signatures of selection in southern Angolan sheep unravel adaptation fo...

Teixeira, F; Chiaia, H; Sebastino, K; Gaspar, J; Afonso, P; Ngola, S; Simão, C; Casimiro, J; Pires, J; Miguel, A; Dala, E; Pires, M; Nanga, P; Santos, D

Natural and artificial selection in African sheep populations has left distinctive genomic signatures. In southern Angola, pastoralist tribes breed fat-tailed sheep adapted to arid and mesic savannas for protein and cultural purposes. This study aims to identify candidate genes associated with productivity and adaptation in these sheep. We sequenced genomes from Namibe (n = 3) and Cunene (n = 5) and compared th...


The Pecari tajacu genome: A tool for its conservation and the study of the Suoi...

Amaral, AJ; Eory, L; Santos, D; Toral, FLB; Delgado, I; Leitão, A; Gama, LT; Archibald, AL

The goal of this study is the development of a high-quality assembly for the Pecari tajacu species. The Suoidea superfamily groups 2 families: Suidae and Tayassuidae. Suidae species inhabit Africa and Eurasia, occupying a wide range of habitats. The same applies to the Tayassuidae species that live in the Americas and were the first from Suoidea to diverge from their common ancestor in North America ~36 Ma. Lin...


Assessing the Potential of PlanetScope Imagery for Iron Oxide Detection in Anti...

Santos, D; Cardoso-Fernandes, J; Lima, A; Ana Teodoro

The increasing demand for critical raw materials, such as antimony-a semimetal with strategic relevance in fire-retardant applications, electronic components, and national security-has made the identification of European sources essential for the European Union's strategic autonomy. Remote sensing offers a valuable tool for detecting alteration minerals associated with subsurface gold and antimony deposits that...

Optimizing Exploration: Synergistic approaches to minimize false positives in p...

Santos, D; Azzalini, A; Mendes, A; Cardoso-Fernandes, J; Lima, A; Müller, A; Ana Teodoro

Pegmatites represent a critical source of raw materials for the European Union's future, emphasizing the need to explore new deposits. Remote sensing plays a pivotal role in early-stage pegmatite exploration, generating prospectivity maps to facilitate field validation. The higher the false positive rate, the higher the time and costs required for field campaigns. This study aims to devise an approach that mini...

Cardoso Fernandes, J; Santos, D; de Almeida, CR; Vasques, JT; Mendes, A; Ribeiro, R; Azzalini, A; Lia Duarte; Moura, R; Alexandre Lima; Ana Teodoro

Due to the current energetic transition, new geological exploration technologies are needed to discover mineral deposits containing critical materials such as lithium (Li). The vast majority of European Li deposits are related to Li-Cs-Ta (LCT) pegmatites. A review of the literature indicates that conventional exploration campaigns are dominated by geochemical surveys and related exploration tools. However, oth...

Mapping NYF pegmatite outcrops through high-resolution Worldview-3 imagery

Santos, D; Mendes, A; Azzalini, A; Cardoso Fernandes, J; Lima, A; Ana Teodoro

Several studies on remote sensing and mineral exploration have been developed or improved in the last decade. However, the low spatial resolution of satellites is a recurring problem in many cases where the mineral or rock is much smaller than the pixel size of the satellite images. This phenomenon, called sub-pixel occurrence, generates an extremely mixed pixel that difficult the performance of conventional cl...


SPECTRAL UNMIXING AND THE POTENTIAL OF WORLDVIEW-3 SATELLITE DATA FOR PEGMATITE...

Santos, D; Mendes, A; Azzalini, A; Cardoso-Fernandes, J; Alexandre Lima; Ana Teodoro

Remote Sensing has been successfully applied in the identification of pegmatitic targets. However, the spatial resolution of open data satellites, which is often much larger than the outcrop size of the target mineral or rock, has been a recurrent challenge in this scientific field. This restricts remote sensing methods that are dependent on large outcrop sizes for successful identification. This work applied s...
