- Living on the shores of the Alboran sea. The neolithic on the coast of Málaga (Spain) a multiproxy approachPublication . Simón-Vallejo, María D.; Lozano-Francisco, M. Carmen; Riquelme-Cantal, José A.; Macías-Tejada, Sara; Camuera, Jon; Uzquiano Ollero, Paloma; Sánchez Marco, Antonio; Garrido-Anguita, Juan M.; Jiménez-Espejo, Francisco; Parrilla-Giráldez, Rubén; Vera-Lozano, José A.; Vera-Peláez, José L.; Cortés-Sánchez, MiguelContext: The coast of Málaga is one of the core areas for the Neolithic in southern Iberia with the earliest occupations dating to the middle of the 8th millennium cal BP. From the outset, evidence shows a fully developed and highly diversified system of agriculture and animal husbandry. The palaeoenvironmental conditions during this period in the southern Iberian Peninsula reveal phases of aridity. Objectives: This study aims to understand how Neolithic communities adapted to these adverse environmental conditions. It also explores the role of wild resources and seasonal patterns in subsistence strategies. Methods: A multiproxy approach was applied, combining regional palaeoenvironmental data with archaeological, archaeofaunal, archaeobotanical and anthropological evidence. The analysis focuses on sites located near aquifer discharges. Results: Fully developed and highly diversified agriculture and herding practices are documented from the earliest Neolithic phases. The challenges posed by arid conditions appear to have been mitigated by settlement in areas linked to major aquifer outlets and by the cultivation of drought-resistant cereals. Multiple lines of evidence suggest a seasonal pattern of occupation, primarily from late autumn to early summer, when marine resources were likely exploited. Neolithic groups may have engaged in regular hunting and gathering activities or maintained interactions with local Epipalaeolithic–Mesolithic populations. Agricultural and pastoral management emerge as key factors for evaluating the contribution of wild resources to their subsistence. Conclusions: The integration of environmental, archaeological and biological records provides a more holistic perspective and better understanding of Neolithic economy and society along the Málaga coast between c. 7.6th—5th millennium cal BP, offering insights into subsistence strategies under arid conditions in a coastal setting.
- Microplastics hot spots at the South Iberian MarginPublication . Bebianno, Maria; Cristina, Sónia; Nathan, Justine; Goela, Priscila; Dias Duarte Fragoso, Bruno; Icely, John David; Moura, DelmindaThe persistent accumulation of microplastics (MPs) in sediments poses ecological risks to benthic organisms and contributes to the broader issue of marine pollution. This study quantitatively analysed MPs in sediments, water and mussels Mytilus galloprovincialis from eleven sites of the South Portuguese coast in two contrasting climatic seasons (summer and winter). MPs were detected in sediments, water, and M. galloprovincialis at all study sites, although their abundance, colour, size, and type varied across compartments, locations, and seasons. Three hot spots of MPs contamination were identified at the South Portuguese coast. In these areas, the concentration of MPs in sediments was three orders of magnitude higher than water and mussels. The MPs identified had distinct colour patterns: transparent particles dominated in sediments, while blue was the most common in water and mussels. A size-dependent accumulation pattern was observed in the sediments, suggesting selective retention of MPs according to natural particle size, and a relationship was observed between MP levels in sediments and in mussels. Polypropylene (PP) and polyethylene (PE) were dominant polymers in sediments while PP, PE and polyethylene terephthalate (PET) were consistently present in water and mussels. Polybuthyl methachrylate (PBMA) was also detected in surface water and ingested by mussels. These findings suggest that variability in MPs abundance and polymer composition is linked to differences in local human activities. They also provide strong evidence for the importance of controlling land-based sources of MPs, particularly those transported to the coastal area by transported by rivers.
