Aziz Ab'Sáber

The contributions of Ab'Saber to science range from the first research of oil camps in Brazil's northeast to surveys of Brazil′s natural realms and the restoration of the history of forests, camps and primitive humans over geologic time in South America. He made central contributions to biology, South American archaeology, and to Brazilian ecology, geology and geography. He has published more than 480 works, most of them scientific publications. Among his scientific proposals are FLORAM, the Code of biodiversity and his theory of refuges related to the Amazon.

Ab'Sáber was the first person to classify scientifically the Brazilian and South-America territory in morphoclimatic domains. He also contributed to the "Pleistocene refuge hypothesis", an attempt to explain the distribution of Neotropical taxa as a function of their isolation in forest fragments during glacial periods, which allowed populations to speciate. He died in 2012 following a heart attack.
