  • Late Quaternary sediments and climatic change in Swaziland in Palaeoecology of Africa and the surrounding islands. Volume 15. Southern African Society for Quaternary research. Proceedings.
  • Lake Besaka, as a groundwater-fed lake which appears to have overflowed eastwards into the Awash during the late Pleistocene and perhaps again during the earliest Holocene, is not a sensitive indicator of climatic change. Only two major
  • change within the past 30,000 years.
  • , palaeontological and archaeological context at the same period. However the data show no qualitative latitudinal change in vegetation during the last 40,000 years.
  • data which show that a long series of conspicuous changes in climate and vegetation occurred over the last 35 000 years. These changes include greater expansions of sub-humid montane, relatively dry savanna and cool ericaceous elements in the Late
  • Relict distribution patterns of aquatic animals: another tool in evaluating Late Pleistocene climate changes in the Sahara and Sahel in Palaeoecology of Africa and the surrounding islands. Volume 14.
  • Olorgesailie. The mineralogy and provenance of the sediments are discussed. The stratigraphic distribution of diatom associations suggest many lake level fluctuations. Alkalinities varied between about 5 and 85 meq/l. Based on alkalinity changes, three main
  • covers the time span of approximately 40 000 to 6 000 years BP. The pollen spectra give indications of semi-arid and more humid periods while colder intervals may have occurred. The results are correlated with changes in lake levels.
  • Lake Malawi levels have been as much as 5 m above modern peak values during the early? Holocene but, until more is known about changes in the overflow, the palaeoclimatic significance of these high levels must remain in doubt. In an attempt to view
  • The physical factors which affected the biological patterns of Africa during the last glacial maximum are discussed. Changes in temperature, humidity and wind force on the continent are discussed in a survey of the evidence on periglacial
  • , possibly related to early Quaternary climatic, tectonic or eustatic changes, has had significant influence on the westward-flowing drainage systems in South West Africa.
