Five centuries of lake deoxygenation and microbial shifts revealed by sedimentary DNA
Expanding global deoxygenation is a major ecological crisis. Oxygen loss in aquatic systems is reshaping ecosystems, altering biodiversity, nutrient cycles, and ecosystem functioning. Microbial communities, as key biogeochemical mediators, are highly responsive to oxygen availability, yet their long-term trajectories under sustained oxygen loss remain poorly understood. This limits our ability to anticipate ecosystem responses to climate-driven d…
Vegetation and Landscape Dynamics of the Iberian Pyrenees During the Last 3000 Years
Modern and Contemporary Times
Late-Holocene forest resilience in the central Pyrenean highlands as deduced from pollen analysis of Lake Sant Maurici sediments
Palynological analysis of the last ca. 4300 cal year BP using a sediment core taken from high mountain (ca. 1900 m elevation) Lake Sant Maurici sediments (southern-central Pyrenees) showed remarkable vegetation constancy during the Bronze Age and the Middle Ages. Records of the Iron Age and the Roman period were missing due to a major sedimentary gap. During the studied periods, the vegetation around the lake was largely dominated by pine ( Pinus…
Modern Analogue Approach Applied to High-Resolution Varved Sediments—A Synthesis for Lake Montcortès (Central Pyrenees)
In Quaternary paleosciences, the rationale behind analogical inference presupposes that former processes can be explained by causes operating now, although their intensity and rates can vary through time. In this paper we synthesised the results of different modern analogue studies performed in a varved lake. We discuss their potential value to obtain best results from high resolution past records. Different biogeochemical contemporary processes …
Subalpine forest dynamics reconstructed throughout the last 700 years in the Central Pyrenees by means of tree rings and pollen
Understanding how climate has modulated forest growth and composition in the past is necessary to predict the influence of the ongoing climate warming on the dynamics of mountain forests. We studied the past dynamics of subalpine Pyrenean forests during the last 700 years by assessing the relationships between sedimentary pollen and tree-ring records, and their link with climatic drivers. We compared the pollen record and the montane pollen ratio…
Vegetation shifts, human impact and peat bog development in Bassa Nera pond (Central Pyrenees) during the last millennium
High-mountain lakes are suitable ecosystems for studying local environmental shifts driven by large-scale climate changes, with potential applications to predict future scenarios. The precise features in the response of species assemblages are not fully understood, and human pressure may often hide climatic signals. To investigate the origin and impact of past environmental changes in high-mountain ecosystems and apply this palaeoecological knowl…
The neotropical Gran Sabana region
The Gran Sabana (GS) is a key region for understanding the origin of neotropical savannas and is an ideal location to test ecological hypotheses on long-term vegetation dynamics under the action of natural and anthropogenic drivers. The conservation of the GS is a controversial issue because of the confluence of disparate cultural and socio-economic interests, with a strong debate surrounding fire practices by indigenous people. Late glacial to H…
Crops and weeds from the Estany de Montcortès catchment, central Pyrenees, during the last millennium
Preliminary report on a mid-19th century Cannabis pollen peak in NE Spain
Cannabis sativa L. (hemp) was introduced in Europe from Asia Minor during classical Greek and Roman times. Since then, hemp pollen abundances between 10% and 80% in Late Holocene sediments have been considered indicative of the local or regional cultivation and/or retting of this plant. In this paper, a unique pollen peak of >60% recorded in Lake Montcortès (pre-Pyrenean foothills, NE Spain) is evaluated as a potential chronostratigraphic marker.…
An 8700-year record of the interplay of environmental and human drivers in the development of the southern Gran Sabana landscape, SE Venezuela
The vegetation of the southern Gran Sabana (SE Venezuela) consists primarily of a treeless savanna with morichales ( Mauritia flexuosa palm stands), despite the prevailing climate being more favorable for the development of extensive rainforests. Here, we discuss the results of our 8700-year paleoecological reconstruction from Lake Encantada based on the analysis of pollen, algal remains, charcoal, and geochemical proxies. We use the findings to …
The 1.5-ka varved record of Lake Montcortès (southern Pyrenees, NE Spain)
The karstic Lake Montcortès sedimentary sequence spanning the last 1548 yr constitutes the first continuous, high-resolution, multi-proxy varved record in northern Spain. Sediments consist of biogenic varves composed of calcite, organic matter and detrital laminae and turbidite layers. Calcite layer thickness and internal sub-layering indicate changes in water temperature and seasonality whereas the frequency of detrital layers reflects rainfall …
