    Relation between century-scale Holocene arid intervals in tropical and temperate zones

    CLIMATE records from lake sediments in tropical Africa, Central America and west Asia show several century-scale arid intervals during the Holocene1–10. These may have been caused by temporary weakening of the mo...

    A 13,000-year climate record from western Tibet

    ALTHOUGH the Tibetan plateau is important in influencing the atmospheric circulation of the Northern Hemisphere1–3, there are only a few continuous palaeoclimate records available, and these are limited to the p...

    Chronology of the major palaeohydrological events in NW Africa during the late Quaternary: PALHYDAF results

    On the basis of African examples, the paper draws attention to some geochemical and sedimentological problems which commonly occur in the establishment of a reliable chronology from lacustrine sediments. New r...

    Diatoms for reconstructing palaeoenvironments and paleohydrology in tropical semi-arid zones

    Palaeoenvironments are reconstructed from the diatom flora of Holocene swamp and lacustrine sediments which lie in closed depressions of the Chad basin (Niger).

    Freshwater to marine-like environments from Holocene lakes in northern Sahara

    Continuous swamp and lacustrine sequences from the northern edge of the Great Western Erg are dated at 9,300–3,000 yr BP. Diatoms, ostracods, molluscs and foraminifera show great changes in salinity, ranging f...

    Transfer functions for estimating paleoecological conditions (pH) from East African diatoms

    Our purpose is to establish the quantitative relationship between recent diatom floras and ecological parameters, in order to extrapolate the results to the past. The parameter pH is here considered as an exam...

    Late Quaternary history of the Nile

    During the intertropical cold dry phase from ∼20,000 to 12,500 yr BP, the aggrading Nile was a braided, highly seasonal river. With a headwaters change to warmer, wetter conditions, it became an incised, sinuo...
