Titles ands were reviewed to identify studies on population-based mean serum 25(OH)D concentrations among Turkish, Moroccan, Indian, and sub-Sahara African populations in Europe, Turkey, Morocco, India, and sub-Sahara Africa.ResultsThe vitamin D status of immigrant populations in Europe was poor ...
Allozyme polymorphism at 15 loci ofwas studied in 7 natural populations from Europe, North and tropical Africa. Morphological traits were studied in nine European and eleven Afrotropical strains.Within a population, the biochemical polymorphisms ofand its siblingare not very different, althoughhas a ...
We have previously shown evidence of strong sex-biased genetic blending in the founding and ongoing history of the Brazilian population, with the African and Amerindian contribution being highest from maternal lineages (as measured by mitochondrial DNA) and the European contribution foremost from paternal...

The Yoruba are the largest ethnic group south of the Sahara with a population of 44 million and are the third largest in Africa. They are not a single group but have common language, history, and culture. They became the most urbanized African civilization before the arrival of Europeans. In...
African Americans were also concentrated in the largest cities, with more than 2,000,000 living in New York City and more than 1,000,000 in Chicago. Detroit, Philadelphia, and Houston each had a Black population between 500,000 and 1,000,000. Names and labels As Americans of African ...
The history of the African diaspora in Europe is still largely misunderstood and has received scant study. Its origins are in the distant time when human society in the modem sense first came into being. In that era tens of thousands of years ago the population of Europe was formed by waves...
Recent developments in population theory have made possible a re-examination of demographic evidence from West Africa which suggests that population growth and migration are primarily responses to changes in the nature of the production system. Precolonial, colonial, and independence period data provide ...
We estimate the size of the African American population in five-year age groups at census dates from 1930 to 1990 using a three-part strategy. For cohorts born after 1935, we follow the U.S. Census Bureau in using classical demographic analysis. To estimate the size of cohorts born before...
But the long-term populationstrends of these species were probably influenced by hab-sitat changes on their breeding grounds in Europe (Bohn-sing-Gaese 1992).sAre these results specific for avian c...Baillie, S. R. and W. J. Peach . 1992 . Population limitation in Palaearctic-African ...
