    Causes of dust size variability in central East Antarctica (Dome B):Atmospheric transport from expanded South American sources during Marine Isotope Stage 22017Ingår i: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 168, s. 55-68Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We here investigate the spatial and temporal variability of eolian dust particle sorting recorded in the Dome B (77 05 S, 94 55 E) ice core, central East Antarctica, during Marine Isotope Stage (MIS) 2. We address the question whether such changes reflect variable transport pathways from a unique source area or rather a variable apportionment from diverse Southern Hemisphere sources transported at different elevation in the troposphere. The Sr-Nd radiogenic isotope composition of glacial dust samples as well as single-particle Raman mineralogy support the hypothesis of a single dust provenance both for coarse and fine mode dust events at Dome B. The southern South American provenance of glacial dust in Antarctica deduced from these results indicate a dust composition coherent with a mixture of volcanic material and minerals derived from metamorphic and plutonic rocks. Additionally, Dome B glacial samples contain aragonite particles along with diatom valves of marine benthic/epiphytic species and freshwater species living today in the northern Antarctic Peninsula and southern South America. These data suggest contribution from the exposed Patagonian continental shelf and glacial outwash plains of southern Patagonia at the time when sea level reached its minimum. Our results confirm that dust sorting is controlled by the relative intensity of the two main patterns of tropospheric dust transport onto the inner Plateau, i.e. fast low-level advection and long-range high-altitude transport including air subsidence over Antarctica.

    A dwarf sabertooth cat (Felidae: Machairodontinae) from Shanxi, China, and the phylogeny of the sabertooth tribe Machairodontini2022Ingår i: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 284, s. 107517-107517, artikel-id 107517Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The tribe Machairodontini is a major lineage of felid sabertooth cats that flourished in the late Cenozoic and included the top predators in the ecosystem of that time. As top predators members of the tribe had a profound influence on the paleoenvironment, yet the evolution and diversification of this tribe are unclear due to a lack of comprehensive revision and phylogenetic study. Here we describe a new dwarfed ecomorph of Machairodontini, Taowu liui gen. et sp. nov., from the Early Pleistocene of northern China,and carry out the best sampled phylogeny of the subfamily to date. Our analyses support that the African Mio-Pleistocene Lokotunjailurus represents an early divergent group, convergent with the Amphimachairodus-Homotheriina lineage in dental traits. The derived Pliocene to Pleistocene subtribe Homotheriina originated in Africa, from Adeilosmilus gen. nov. kabir or very a closely related taxon. Taowu liui gen. et sp. nov. belongs to a sister clade to Homotheriina. The Plio-Pleistocene Homotheriina of theNew World belong to a monophyletic group in which Ischyrosmilus-Xenosmilus show a gradual adaptation to handling slow and powerful prey, whereas the true Homotherium only appeared after theMiddle Pleistocene, in a separate intercontinental dispersal event.

    Seasonal variability in temperature trends and atmospheric circulation systems during the Eemian (Last Interglacial) based on n-alkanes hydrogen isotopes from Northern Finland2021Ingår i: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 273, s. 107250-107250, artikel-id 107250Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Last Interglacial warm period, the Eemian (ca. 130-116 thousand years ago), serves as a reference for projected future climate in a warmer world. However, there is a limited understanding of the seasonal characteristics of interglacial climate dynamics, especially in high latitude regions. In this study, we aimto provide new insights into seasonal trends in temperature and moisture source location, linked to shifts in atmospheric circulation patterns, for northern Fennoscandia during the Eemian. Our study is based on the distribution and stable hydrogen isotope composition (dD) of n-alkanes in a lake sediment sequence from the Sokli paleolake in NE Finland, placed in a multi-proxy framework. The dD values of predominantly macrophyte-derived mid-chain n-alkanes are interpreted to reflect lake water dD variability influenced by winter precipitation dD (dDprec), ice cover duration and deuterium (D)-depleted meltwater. The dD values of terrestrial plant-derived long-chain n-alkanes primarily reflect soil water dD variability modulated by summer dDprec and by the evaporative enrichment of soil and leaf water. The dDprec variability in our study area is mostly attributed to the temperature effect and the moisture source location linked to the relative dominance between D-depleted continental and polar air masses and Denriched North Atlantic air masses. The biomarker signal further corroborates earlier diatom-based studies and pollen-inferred January and July temperature reconstructions from the same sediment sequence. Three phases of climatic changes can be identified that generally follow the secular variationsin seasonal insolation: (i) an early warming trend succeeded by a period of strong seasonality (ii) a midoptimum phase with gradually decreased seasonality and cooler summers, and (iii) a late climatic instability with a cooling trend. Superimposed on this trend, two abrupt cooling events occur in the early and late Eemian. The Sokli dD variability is generally in good agreement with other North Atlantic and Siberian records, reflecting major changes in the atmospheric circulation patterns during the Eemian as a response to orbital and oceanic forcings.

    First small-sized Dinofelis: Evidence from the Plio-Pleistocene of North Africa2021Ingår i: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 265, artikel-id 107028Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We describe small-sized specimens of the metailurine felid Dinofelis from a new Plio-Pleistocene site in North Africa. Dinofelis is a genus of saber-toothed cats mainly recorded from East and South Africa with numerous leopard to jaguar-sized species. The described specimens, clearly smaller than all the other African Dinofelis, resemble isolated remains from the Late Pliocene of France and the Early Pleistocene of Africa. Present evidence suggests that our form represents a new species and/or new lineage of Dinofelis, smaller and probably occupying a different ecological niche compared to the previously known members of the genus, and thus it adds complexity to the high intraspecific competition among large carnivorans in the Plio-Pleistocene of Africa.

    Niche evolution versus niche conservatism and habitat loss determine persistence and extirpation in late Neogene European Fagaceae2023Ingår i: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 300, s. 107896-107896, artikel-id 107896Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An increasing body of palaeobotanical data demonstrates a series of Pliocene and Pleistocene extirpationsand extinctions of plant lineages in western Eurasia, which are believed to have been determinedby the climatic properties of their related East Asian and North American sister lineages.We investigatedthe diversity of a widespread northern hemispheric plant family, Fagaceae, during the Late Pliocene ofPortugal. We found a high diversity of Fagaceae comprising extant and extinct lineages. Dispersed pollenof Castanopsis and Quercus sect. Cyclobalanopsis represent the youngest records of these Himalayan-Southeast Asian groups in western Eurasia. Likewise, fossil-species of Quercus sect. Lobatae and theNorth American clade of sect. Quercus are the youngest records of these modern New World groups inwestern Eurasia. For the extinct Trigonobalanopsis, the pollen record of Portugal is the youngest known ofthis genus. Climate data of modern representatives demonstrate that a deterministic model can explainonly a part of the Pliocene and Pleistocene extirpations. Modern cold month mean temperatures ofCastanopsis and Quercus sect. Cyclobalanopsis and their last occurrences in western Eurasia in the Pliocenefit with a deterministic model (niche conservatism). In contrast, survival or extirpation of groupswith high cold tolerance appear to have been more complex. Here, niche evolution, abundance anddiversity of a lineage during pre-Pleistocene times, and habitat availability/loss determined the fate ofFagaceae lineages in western Eurasia.

    The Casa del Diablo cave (Puno, Peru) and the late Pleistocene demise of megafauna in the Andean Altiplano2018Ingår i: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 195, s. 21-31Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    During the Late Quaternary Extinction event South America lost ~83% of all its late Pleistocene megafaunal genera. As in other regions of the world, the debate about the possible drivers behind these extinctions revolves around the role of humans arriving into the continent and on the effect of the climatic changes characteristic of the Pleistocene-Holocene transition. The availability of precise chronological information, in order to estimate the timing of extinction of the different taxa affected, is critical for solving such debate. Here we present an updated study of the late Pleistocene mammalian deposits from Casa del Diablo Cave (CdD) in the Altiplano of Peru. The study includes an updated list of the mammalian faunas found in the cave and 11 taxon-specific XAD radiocarbon dates from extinct and extant megafauna bones.We compare this new chronology to the timing of major environmental changes and human arrival in the area, as well as with other megafaunal discoveries from the high Andes. The radiocarbon dates from CdD fall in the time window between 23 and 12.8 cal kyr BP. Compared to other records of extinct megafauna in the high Andes, the one from CdD presents in general younger occurrences. No temporal overlap between humans and extinct megafauna emerges from comparing first dates of appearance of humans in the Altiplano, and last appearance dates of extinct megafauna from CdD. However, the possibility of temporal overlap among the records becomes evident when we compare confidence intervals calculated to estimate true times of human arrival and megafaunal local extinctions.
