The archaeological site of Leceia is a Chalcolithic settlement with one of the largest amounts of metal artefacts in the Lisbon peninsula, although the absence of ores and smelting remains suggests that local metallurgical operations were essentially related to the last stages of the chaine opératoire, namely the casting and forging of artefacts. In fact, the local archaeological record shows several ingots inc...
Copper was the first metal to be intentionally obtained, with the first manifestations of its metallurgy appearing in the archaeological record in contexts of the Portuguese territory dating back to the beginning of the 3rd millennium BC. On the other hand, taking into account the sets of artefacts and contexts associated with these remains, it becomes possible to determine the function and use of copper. It is...
Excavations carried out under the auspices of the Almada City Council, between 1989 and 1991 in the churchyard of S. Paulo, within the urban area of the city of Almada, led to the identification of what remains of an artificial cave, excavated in carbonate sediments of the Miocene, of which the burial chamber and a small section of the corridor adjacent to it were completely explored. The excavations led to the...
The knowledge on taxonomic diversity of arthropods is key to better understanding the biodiversity patterns and processes and guiding sustainable conservation strategies and practices. In the Azores, terrestrial arthropods are relatively well-inventoried following the publication of comprehensive checklists that have been regularly updated. Nevertheless, every year, new species are found as a result of new arri...
Background The Japanese Beetle, Popillia japonica Newman, 1838 (Coleoptera, Rutelidae), is a univoltine agricultural pest that poses a serious threat to various agricultural crops. For more than 16 years, the Azorean official authorities have implemented a Long-Term Ecological Research (LTER) programme that is crucial for understanding the dynamics of insect pests, such as the Japanese Beetle, and their impacts...
The work presents a revaluation of a pioneer research about the copper provenance in the Chalcolithic settlement of Leceia (Oeiras, Portugal) considering theoretical developments in the application of lead isotope analyses, in addition to the recent publication of the large IBERLID database including copper ores from Iberian Peninsula. Therefore, the lead isotope ratios of 14 copper artefacts and copper prills ...
Although in recent years the prehistoric metallurgy of southwestern Iberian Peninsula has become increasingly well understood, the southernmost region still requires additional research. This work presents the technological study of artefacts from burial contexts located in this area, namely the necropolises of Anta do Malhão and Soalheironas (Algarve region). Typologies of metalwork and pottery ascribe the sin...
Marine food–reliant subsistence systems such as those in the African Middle Stone Age (MSA) were not thought to exist in Europe until the much later Mesolithic. Whether this apparent lag reflects taphonomic biases or behavioral distinctions between archaic and modern humans remains much debated. Figueira Brava cave, in the Arrábida range (Portugal), provides an exceptionally well preserved record of Neandertal ...
