Genetic relationships were studied among 23 isolates of Sphaeropsis sapinea collected from China, the United States, England, South Africa and Chile by using a random amplification of a polymorphic DNA (RAPD) analytical method.
      
Restriction endonucleases (RENs) were detected in 650 microbial strains isolated from water columns and bottom sediments of deep rift lakes, Baikal (Russia) and Nyasa (Southeastern Africa).
      
During the first period, the primary natural foci in Eurasia were formed and, during the second period, synanthropic (rat) and secondary natural foci appeared with the participation of humans in Africa, The New World, and on some tropical islands.
      
Identification and Genesis of the Mixed-Layer Lizardite-Saponite Phase in a Kimberlite Pipe, South Africa
      
In autolithic breccia of a kimberlite pipe in South Africa, the ordered mixed-layer lizardite-saponite phase was first identified in rocks containing a mechanical mixture of lizardite and saponite or only saponite in association with lizardite.
      
New data on hydrocarbons in auriferous conglomerates of the Witwatersrand ore region, Republic of South Africa
      
Genesis of deposits in the world's largest Witwatersrand auriferous region (South Africa) remains a debatable issue over several decades.
      
The processes were studied based on the Paleogene Fergana Bay and bottom sediments of the Sea of Aral, as well as DSDP core materials from the Atlantic (near the western coast of Africa) and Indian (the Arabian Peninsula area) oceans.
      
Some other mtDNA variants in the Nogay population belong to the M1 haplogroups typical of northeastern Africa and U2 characteristic of Indian populations.
      
Analysis was based on the known dating of the variola virus (VARV) transfer from Western Africa to South America and previous data on the phylogenetic relatedness of modern West African and South American isolates of VARV.
      
Hordein Polymorphism in Barley Varieties from Northern Africa
      
We suggest that polymorphism at the hordein-coding loci in the populations examined has been mainly formed beyond Northern Africa, where barley has been repeatedly introduced.
      
Sixty-two populations from North, Central, and Southeast Asia, Eastern and Western Europe, America, East Africa, Australia, and Melanesia have been examined.
      
Nevertheless, interannual fluctuations in the dates of arrival are well manifested in both early arriving species wintering in Europe and late-arriving species wintering in Africa.
      
Association of simple (1T and 3R) and two complex (nonstandard) orthogonal polytypes of the serpentine mineral lizardite from the Catoca kimberlite pipe (West Africa) association is revealed from oblique-texture electron diffraction patterns.
      
Some new QE results obtained for the 86Kr + 208Pb system at iThemba LABS in South Africa will be presented.
      
The hypothesis is proposed that recent climate warming has caused changes in the timing of not only the arrival of birds in Europe but also of their spring migrations from Africa.
      
Six new genera and eight new species are described from South and Central Americas, South Africa, and Southeastern Asia.
      
A new species of digger wasps of the genus Belomicroides (Hymenoptera, Crabronidae, Oxybelini) from North Africa
      
The new species of digger wasps, Belomicroides rufus, is described from North Africa.
