• Arqueologia i ramaderia a l’alta muntanya. Anàlisi espacial de les evidències arqueològiques del Parc Nacional d’Aigüestortes i Estany de Sant Maurici

  Archaeological research in Europe's high mountain regions reveals significant human occupation from the early Holocene, challenging perceptions of these areas as predominantly natural. A study analyzing spatial distributions of archaeological sites in the Madriu-Perafita-Claror Valley, a rugged part of Catalonia's Pyrenees, found that site locations are strongly dependent on current meadows and grasslands, as well as proximity to water, while winter solar exposure plays no significant role. This suggests that human activity in these environments has been more persistent and widespread than previously thought.

• Grass silica short cell phytoliths in Pyrenean subalpine grasslands: taxonomy and palaeoecological relevance

  A pioneering phytolith reference collection for the Central Pyrenees reveals that grass silica short cell phytoliths (GSSCPs) can serve as highly diagnostic proxies for reconstructing past vegetation dynamics in subalpine grasslands. The study identifies 29 distinct GSSCP sub-morphotypes, each strongly associated with specific grass lineages and ecological habitats, including mesic pastures, open stress-prone grasslands, xerophilous slopes, and disturbed or hydromorphic meadows. Multivariate analyses confirm that these morphotype-habitat associations structure assemblages along elevational gradients, providing unprecedented taxonomic and ecological resolution for palaeoecological reconstructions. This ICPN-compliant framework enhances the potential to track long-term pastoral land-use impacts and climate-driven shifts in mountain ecosystems.

• Neolithic pastoralism and plant community interactions at high altitudes of the Pyrenees, southern Europe

  A groundbreaking sedimentary ancient DNA analysis from the Madriu-Perafita-Claror Valley in the Pyrenees reveals that Neolithic pastoralism, marked by continuous sheep and cattle presence starting 6500 and 5900 years ago respectively, played a significant role in shaping high-altitude Mediterranean landscapes. This challenges previous assumptions about sporadic Neolithic pastoral activity, demonstrating instead a sustained interaction with alpine ecosystems. The study identifies a major plant community shift around 6000 years ago, where deciduous forests transitioned to diverse open grasslands, becoming dominant by 4200 years ago. This transformation aligns with regional cooling climate trends and the continuous presence of domesticates, suggesting a synergistic relationship between human activity and environmental change during the Neolithic period.

• Del territorio al asentamiento y del asentamiento al territorio: la investigación arqueológica en áreas de montaña y alta montaña en el Pirineo central

  Archaeological research in high-altitude mountain regions, exemplified by the Madriu-Perafita-Claror Valley in the Pyrenees, reveals that long-term territorial sequences and landscape-scale studies are becoming defining features of this emerging discipline. The work of the Grupo de Arqueología de la Alta Montaña (GAAM) over two decades highlights how high-altitude archaeology uniquely integrates spatial methodologies to address social dimensions of human existence. Unlike traditional settlement-focused approaches, this research emphasizes territory as a primary object of study, necessitating innovative methodological designs. A case study illustrates the theoretical relevance of this approach, suggesting that while strengths exist, further attention is needed on specific challenges. The findings underscore the potential for high-altitude archaeology to deepen our understanding of human-landscape interactions in mountainous regions.

• L’arqueologia del paisatge aplicada a l’estudi dels espais altimontans: experiències a les capçaleres del Ter i del Segre (el Ripollès, la Cerdanya, Andorra)

  Research in the Madriu-Perafita-Claror Valley reveals that high-altitude landscapes in the Eastern Pyrenees, spanning 1,800 to 2,800 meters above sea level, have been shaped by human activity since the Neolithic period. This challenges the long-held perception of these areas as marginal and uninhabited. The study employs a specialized landscape archaeology methodology, combining prospection strategies, sampling techniques, and paleoenvironmental approaches to document ancient human occupation in the headwaters of the Ter and Segre rivers (Ripollès, Cerdanya, Andorra). By integrating interdisciplinary data, the research demonstrates that these alpine environments have been actively humanized for millennia, offering new insights into past adaptive strategies in high-altitude regions.

• Cabañas, cercados y otras construcciones en piedra: tiempo, espacio y sociedad en los paisajes de alta montaña del Pirineo

  Archaeological research in the Madriu-Perafita-Claror Valley, a UNESCO World Heritage Site within the Pirineos, reveals a rich diversity of pastoral practices spanning centuries. The study introduces a novel framework for classifying stone structures—such as cabins and enclosures—based on their temporal and functional characteristics, enabling deeper sociohistorical interpretations. Applying this methodology to the Aigüestortes and Estany de Sant Maurici region, the research identifies distinct patterns of land use and human activity in high-altitude landscapes, challenging traditional narratives of seasonal mobility and resource management in the Pyrenees.

• Climatic and Anthropogenic Drivers of Forest Succession in the Iberian Pyrenees during the Last 500 Years: A Statistical Approach

  Forest succession in the Madriu-Perafita-Claror Valley, a UNESCO World Heritage Site in the Iberian Pyrenees, has been significantly influenced by both climatic and anthropogenic factors over the last 500 years. The study reveals that dominant tree taxa such as Quercus, Betula, and Pinus exhibit strong relationships with summer temperature, drought, and autumn precipitation, showing immediate and delayed responses to these climatic drivers. A notable closed path in regional succession was identified, transitioning from pine-dominated forests due to human-induced clearing (16th–18th centuries) to natural forest recovery (18th–20th centuries), driven by reduced human pressure and rising temperatures. This statistical analysis provides critical insights for predicting future successional trends under changing climates, highlighting the complexity of ecological relationships and the need to address response lags in future research.
