Abstract

A new 20 m sequence is presented which is based on 279 spectra derived from a coring at Le Bouchet lake (Massif Central, France). The vegetational history of this region is described back to the end of the last Interglacial (Ribains interglacial). The two Preglacial (early Glacial) forested interstadials (St-Geneys 1 and St-Geneys 2) are evidence for the first time in the Massif Central. In spite of the altitude of the site (1200 m), they suggest a quite temperate vegetation, with the same mesophilous character as during the Holocene. The Pleniglacial appears to be threefold, with two cold episodes (Lower and Upper Pleniglacial) divided by a long complex period of moderate climatic improvement. The vegetation history of this mountain region is compared with that evidenced for the same period on the basis of the sequence of Les Echets at a lower altitude (267 m). Botanical and climatic inferences are discussed.

Résumé

Construite sur la base de 279 spectres polliniques, une nouvelle séquence de 20 m, prélevée par carottier dans le lac du Bouchet (Massif Central, France) est présentée. L'histoire de la végétation de cette région est révélée depuis la fin du dernier interglaciaire (interglaciaire de Ribains). Mis en évidence pour la première fois dans le Massif Central, les deux interstades forestiers du Préglaciaire (= glaciaire précoce) (St-Geneys 1 et St-Geneys 2) témoignent, malgré l'altitude de 1200 m, de végétations très tempérées, aussi mésophiles que celles de l'Holocène. Le Pleniglaciaire apparaît tripartite, comportant deux ensembles froids (Pléniglaciaire inférieur et Pleniglaciaire supérieur), séparés par une longue période complexe d'amélioration modérée. L'histoire de la végétation de cette région de montagne (1200 m) est comparée, pour la même période, à celle révélée par la séquence des Echets (267 m). Les implications botaniques et climatiques de cette comparaison sont discutées.

Palaeoenvironmental changes in the southwestern Mediterranean (ODP site 976, Alboran sea) during the MIS 12/11 transition and the MIS 11 interglacial and implications for hominin populations
2023, Quaternary Science Reviews
The transition from the Marine Isotope Stage (MIS) 12 glacial (ca. 478–424 ka BP) to the MIS 11 interglacial (ca. 424–365 ka BP) is one of the most remarkable climatic shifts of the Middle Pleistocene and is regarded as a phase of major behavioural innovation for hominins. However, many of the available pollen records for this period are of low resolution or fragmented, limiting our understanding of millennial-scale climatic variability. We present a high-temporal resolution pollen record that encompasses the period between MIS 12 and MIS 10 (434–356 ka BP), recovered from the Ocean Drilling Program (ODP) Site 976 in the Alboran Sea. This study aims to provide new insights into the response of vegetation during the transition and to highlight patterns of climatic variability during MIS 11.
The ODP Site 976 pollen record shows the shift from glacial to interglacial at 426 ka BP, highlighted by the transition from Pinus, herbaceous and steppic taxa to temperate and Mediterranean taxa. A climatic optimum for temperate and Mediterranean taxa is identified around 426–400 ka BP, equivalent to substage MIS 11c and synchronous with the maxima in SSTs, greenhouse gas concentrations and insolation. A phase with increased Pinus and Cedrus indicates the return to colder and more arid conditions during substage MIS 11b (400–390 ka BP). Substage MIS 11a (390–367 ka BP) is marked by a period of short-term warming followed by gradual cooling, until the return of glacial conditions during MIS 10. Forest contractions have been linked with high- and moderate-intensity climate events also observed in other pollen records and proxies from the Mediterranean and North Atlantic.
Our results confirm the intense shift during the MIS 12/11 transition and show that this region is sensitive to millennial-scale climatic variation during MIS 11. The forest contractions observed in our record during events of millennial-scale variability appear to be less intense than in the central and eastern Mediterranean. This suggests that the southwestern Mediterranean may have been less variable during periods of climatic deterioration, thereby representing a possible ecological niche for vegetation. This may have provided a source of subsistence for hominins during harsher conditions, thus contributing to their demographic expansion and technological innovations.

New climatic approaches to the analysis of the middle Paleolithic sequences: Combined taxonomic and isotopic charcoal analyses on a Neanderthal settlement, Les Canalettes (Aveyron, France)
2021, Quaternary International
Over the last decade, several studies have indicated the potential for the δ¹³C isotope signal of charcoals to act as a new local paleoclimatic/paleoenvironmental proxy, complementary to taxonomic analyses.
These studies mainly focused on archeological charcoal from the Holocene series, but the potential of the method to be applied Pleistocene sequences is still under debate. Understanding climate-driven variability in stable carbon isotope ratios of modern samples is fundamental for the accurate characterization of past climate information based on the δ¹³C of charred material. In a previous study, we laid the methodological foundation to apply the method to Pleistocene contexts.
Here, we present the δ¹³C isotopic signal from Pinus spp. charcoal in a well stratified middle Paleolithic site: “Les Canalettes” (Aveyron, France). We demonstrate that the use of isotopic analyses on ancient charcoal of the genus Pinus from the quaternary period could provide a reliable paleoclimatic marker with high resolution and provide data that is complementary to taxonomic studies. A continuous increase in humidity is observed, with a warming episode identified at the top of the sequence. These results place the occupation of the site in a less rigorous phase at the beginning of MIS 4 and underline the importance of the Causses in the mobility system of several generations of Neanderthals.
An overview of Alpine and Mediterranean palaeogeography, terrestrial ecosystems and climate history during MIS 3 with focus on the Middle to Upper Palaeolithic transition
2020, Quaternary International
This paper summarizes the current state of knowledge about the millennial scale climate variability characterizing Marine Isotope Stage 3 (MIS 3) in S-Europe and the Mediterranean area and its effects on terrestrial ecosystems. The sequence of Dansgaard-Oeschger events, as recorded by Greenland ice cores and recognizable in isotope profiles from speleothems and high-resolution palaeoecological records, led to dramatic variations in glacier extent and sea level configuration with major impacts on the physiography and vegetation patterns, both latitudinally and altitudinally. The recurrent succession of (open) woodlands, including temperate taxa, and grasslands with xerophytic elements, have been tentatively correlated to GIs in Greenland ice cores. Concerning colder phases, the Greenland Stadials (GSs) related to Heinrich events (HEs) appear to have a more pronounced effect than other GSs on woodland withdrawal and xerophytes expansion. Notably, GS 9-HE4 phase corresponds to the most severe reduction of tree cover in a number of Mediterranean records. On a long-term scale, a reduction/opening of forests throughout MIS 3 started from Greenland Interstadials (GIs) 14/13 (ca. 55–48 ka), which show a maximum in woodland density. At that time, natural environments were favourable for Anatomically Modern Humans (AMHs) to migrate from Africa into Europe as documented by industries associated with modern hominin remains in the Levant. Afterwards, a variety of early Upper Palaeolithic cultures emerged (e.g., Uluzzian and Proto-Aurignacian). In this chronostratigraphic framework, attention is paid to the Campanian Ignimbrite tephra marker, as a pivotal tool for deciphering and correlating several temporal-spatial issues crucial for understanding the interaction between AMHs and Neandertals at the time of the Middle to Upper Palaeolithic transition.
Early Holocene Thermal Maximum recorded by branched tetraethers and pollen in Western Europe (Massif Central, France)
2020, Quaternary Science Reviews
The evolution of temperatures during the Holocene is controversial, especially for the early Holocene. The occurrence of the Holocene Thermal Maximum (HTM) during the early Holocene has recently been reconsidered and seasonal biases have been suggested in the paleoclimatic proxies. High regional variability and a low number of reliable and continuous quantitative reconstructions compared with the oceanic realm further complicate study of the Holocene climate in the continental realm. We analyzed branched glycerol dialkyl glycerol tetraethers (brGDGTs), an organic paleothermometer, and palynological signals as part of a multiproxy analysis of the sedimentary record from Lake St Front, in the Massif Central (France). Identification of a shift in brGDGT sources through the Holocene required removing terrigenous influences from the temperature signal. BrGDGT- and pollen-inferred paleotemperature reconstructions (based on the Modern Analog Technique and the Weighted Averaging Partial Least Squares method) were compared. Both showed a thermal maximum during the early Holocene followed by a decrease of temperatures. We evaluated biases which could potentially influence the reconstructed signal. There was no evidence for a summer temperature bias either for brGDGT-derived temperatures or for pollen-derived temperatures. The Lake St Front data, in agreement with other regional records, confirm the occurrence of the HTM as a general warm period during the early Holocene followed by mid-Holocene cooling in Western Europe and suggest that seasonal biases are not the main explanation of the Holocene conundrum — the disagreement between model simulations and proxy-based temperature reconstructions for the northern hemisphere.
Impact of human activities and vegetation changes on the tetraether sources in Lake St Front (Massif Central, France)
2019, Organic Geochemistry
The distribution of branched glycerol dialkyl glycerol tetraethers (brGDGTs) has been shown to correlate with mean annual air temperature and is increasingly used for paleoclimate reconstructions, in particular in lakes. Numerous studies have reported in situ production of brGDGTs in lakes. These brGDGTs have different distributions compared with those produced in soils and their mixing hampers paleoclimate reconstructions. Very few tools exist to determine brGDGT sources in the present and to trace their changes in the past linked with environmental changes of climatic or anthropogenic origin. While human activities are known to affect both soil and aquatic ecosystems, particularly bacterial communities, the specific impacts on brGDGT distributions are poorly investigated. High resolution analyses of brGDGTs were carried out on Holocene sediments and catchment soils of Lake St Front (Massif Central, France) in association with sedimentological, palynological, and geochemical analyses. Comparison of brGDGT distributions in sediments and soils revealed their mixed origin. For the first time, we tested the reliability of the ΣIIIa/ΣIIa ratio in lakes which indicated a gradual shift from aquatic to terrigenous brGDGT sources over the Holocene. This shift was supported by sedimentological and geochemical indices. Three events with a high proportion of terrigenous brGDGTs (6–5.5, 2.8–2.5, and 2–0.2 kyr cal BP) coincide with changes in vegetation in the catchment area, driven by climate and/or human activities. This suggests that vegetation modifications in the watershed impact brGDGT distributions and may thus bias brGDGT-based paleoclimatic reconstructions.
