A research team led by Prof. Dr. Klement Tockner, Director General of the Senckenberg Gesellschaft für Naturforschung and Professor of Ecosystem Sciences at the Goethe University Frankfurt, has investigated the relationship between cultural and biological diversity for selected oases in the Sahara.
, the researchers show that oases are centers of biocultural diversity, using Algeria as a concrete example. Since culture and biodiversity are particularly closely linked in these unique desert habitats, they should be considered together when it comes to measures for sustainable use and protection, postulate the researchers.
Arid regions are home to diverse nomadic cultures, a unique diversity of fauna and flora, and a quarter of the world's languages. Whilein arid areas is lower than in humid habitats such as tropical forests, deserts are home to a variety of particularly well-adapted and unique animals and plants. At the same time, diversity within species is especially pronounced due to the varying features and the isolation of individual ecosystems.
"Date palm oases are a typical example. In addition to the economic importance of the fruits, they exhibit high genetic diversity and provide habitats and refuges for a variety of animals. Here, the close link between the evolution of human culture and biodiversity is particularly evident." To better understand the potential mechanisms of biocultural diversity in the Sahara, the scientists took a closer look at Algeria's oases and analyzed the interrelationships among various factors of biological and"We studied 77 very different oases and 18 oasis groups. Collectively, the oases harbor 552
