This study focuses on the recovery and identification of ancient DNA (aDNA) from tropical subfossil bone assemblages. Materials from multiple archaeological sites spread across three valleys on Nuku Hiva (Marquesas Islands) in the cultural historical region of East Polynesia are used as a case study. We illustrate how aDNA sampling strategies, laboratory protocols, PCR primer selection, and sequencing methods can be optimised to improve the recovery and taxonomic identification of aDNA from tropical subfossil samples. Sanger sequencing was initially employed as a preliminary approach to assess the quality of aDNA samples. Subsequently, a high-throughput technique, bulk bone metabarcoding (BBM), was utilised for pooled specimens to recover and sequence taxonomically diagnostic ‘barcoding’ regions of DNA. To ensure robust identifications, we constructed a custom reference database tailored to our genetic markers and developed a novel decision tree framework to assign each aDNA sequence to a well-supported taxonomic level. Our application of rigorous bioinformatic tools enabled us to quantify the ability of our genetic markers to identify taxa, and provided a replicable framework for subsequent taxonomic identifications. Our BBM analyses detected a wide range of vertebrate taxa, including birds, fish, mammals, and reptiles. Here we use the archaeological seabird results to illustrate the efficacy of BBM and the outcomes of our iterative approach to enhance aDNA recovery and taxonomic identification. Our analyses provide the first well-dated pre-Western avifaunal records for Nuku Hiva Island, including three seabird taxa that are new to the wider archaeological record of the Marquesas Islands of Polynesia.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"758 ","pages":"Article 110099"},"PeriodicalIF":1.8,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145980473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The C9001C cores are 365.3 m long and extend to near the Matsuyama-Brunhes geomagnetic polarity boundary. These cores consist of olive-black to dark olive-gray diatomaceous silty clay, with multiple interbedded glassy tephra layers. Previous studies identified more than 50 tephra and cryptotephra layers in the cores, of which 21 had been correlated with source volcanoes. In this study we collected 9 tephra layers (8 visible tephra layers and 1 cryptotephra layer). The newly correlated tephras in C9001C are derived from several regions, including Tohoku (T-6, Hkd-Ku), Hokkaido (Ko-i, C-2, Osr, Mb-1, Kp VIII). Based on similarities in glass composition, two tephra layers are correlated with tephras from the Kyushu region. One of these layers is interpreted as a probable reworked deposit of ACP4, whereas the other is likely derived from a previously undocumented large-magnitude eruption of Aso. Ages constrained by the C9001C age model are estimated as follows: Ko-i (36.8 ± 0.9 ka), reworked ACP4 (39.4 ± 1.0 ka), C-2 (44.6 ± 1.1 ka), undocumented Aso tephra (∼138 ka), T-6 (∼141 ka), Osr (∼189 ka), Mb-1 (∼218 ka), KpVIII (219 ka), Hkd-Ku (724 ka?).</div><div>Detailed correlation of tephra layers with their source volcanoes allows a re-evaluation of the frequency and dispersal of tephras from these large-scale eruptions. Using thickness data from the C9001C cores, we assess the eruption magnitude of newly correlated tephras. Estimated magnitudes are ∼ M5.4 for Ko-i and T-6, M4.4–6.9 for Osr. For the undocumented Aso tephra, Mb-1, KpVIII, and Hkd-Ku, available thickness data are too limited to estimate reliable eruption magnitudes. However, considering the observed thicknesses in the C9001C cores and distances from their sources, the undocumented Aso tephra and KpVIII likely represent substantially large eruptions, whereas Hkd-Ku may represent a smaller event than previously inferred. These correlations provide new constraints on eruption ages and the extent of tephra dispersal, both of which were previously unquantified.

The analysis of seabed morphology, erosional and depositional patterns, and sedimentary lithofacies of the late glacial marine geology and postglacial stratigraphy in QCSt collectively allows interpretation of the sequence of processes that formed, shaped, and filled this region. Four primary stratigraphic units were delineated: bedrock, moraines, glaciomarine deposits, and postglacial deposits, along with their seafloor distributions.

Sand and silt units preserved within the organic deposits of these floodplain-impounded features represent relatively large flood events and provide an opportunity to establish the frequency of extreme flooding in the region beyond the timespan of instrumental and historical records, thereby helping to reduce uncertainty around future tropical cyclone activity in a warming world. However, absolute age estimates for these sequences have been limited to radiocarbon dating of organic units, restricting flood history reconstruction. This study had two inter-related aims. Firstly, to evaluate the use of optically stimulated luminescence (OSL) dating for chronicling clastic sediments associated with the floodplain's blocked-valley lakes. Secondly, in combination with radiocarbon dating and Bayesian age-depth modelling, to reconstruct flood history across three sites on the Mfolozi floodplain and investigate the climatic factors that drove past extreme flooding in the region. The Finite Mixture Model (FMM) applied to single grain OSL data was identified as the most suitable equivalent dose (D_e) model, producing age estimates that either aligned with historical records and/or accounted for the largest population of grains with a common dose. The deposition models developed provide evidence for the occurrence of multiple extreme floods since the first event identified at 7.2 ka, providing the first long-term flood record for the region. Comparison of the Mfolozi palaeoflood record with independent sedimentary hydroclimatic evidence from the region indicates a historical tendency for more frequent extreme floods during weakened El Niño conditions (i.e., La Niña or neutral ENSO phases).

The cave provides rare evidence of human occupation spanning from the Late Upper Palaeolithic through the Middle Ages. Geoarchaeological, sedimentological, and micromorphological analyses of the cave deposits elucidate the interplay between human occupation, sedimentary processes, and environmental change in a karstic landscape strongly influenced by subterranean hydrology. The stratigraphic sequence documents alternating phases of fluvial sedimentation, frost-related reworking, and human use of the cave. The mineral composition of the deposits, dominated by siliciclastic grains derived from distant Triassic formations and possibly reworked loess, confirms the cave's hydrological connection to external catchments. Sediment architecture reveals periodic flooding from the underground Đulin Ponor–Medvedica–Izvor-Špilja Gojak cave system, which repeatedly transformed the cave into a spring outlet. Periodical erosion and redeposition of sediments generated gaps and mixed layers within the cultural succession, and disrupted the stratigraphic continuity. Epigravettian layers reveal short-term occupation episodes by Late Upper Palaeolithic foragers, while an <em>in situ</em> Mesolithic hearth attests to later visits during more temperate conditions. Sporadic Copper and Bronze Age activity reflects shifting land-use strategies, mostly pastoral. The absence of Neolithic layers and remains hints to possible erosional removal of the Neolithic horizon. Micromorphological evidence of periglacial structures, combustion features, and dung accumulations, demonstrates subsequent and/or alternating phases of cold-climate sedimentation, dwelling, and pastoral use.
