A team of researchers from the United Arab Emirates University (UAEU) has succeeded in discovering an unknown type of crustacean ‘Diplostraca’ in the animal kingdom of the Arabian Peninsula.

The team from the Department of Biology, Faculty of Science of the University, in collaboration with several researchers and international centers in Russia,

Published in the world’s most prestigious scientific journal, the study was led by Professor Waleed Hamza from the Department of Biology, Faculty of Science, UAE University, in collaboration with Professor Alex Kotov and Anna Nertina, a researcher at the Severtsov Institute, Russia, Ph.D. in Ecology and Evolution, Dr. Khaled Amiri – Director of the Khalifa Center for Genetic Engineering and Biotechnology, a researcher at the Papanin Institute of Biology of Inland Waters of the Russian Academy of Sciences, a master student in the Department of Biology, and Sharma Al Neyadi, who spent 21 days at the Russian Academy, perfecting her with the state-of-the-art camera Lucida ‘s paintings.

Professor Waleed Hamza (Principal Investigator), from the Department of Biology, UAE University, said: “I believe that the discovery of new species that grow in temporary freshwater bodies will open doors for many researchers to explore different environments, not only in the United Arab Emirates, but also in Arabian Peninsula.

“There is still much to discover in the region, and indeed, expanding our research field and collaborating with world-class institutions will positively enhance our research capabilities, especially when young Emirati researchers are involved, which will lead to building a country capable of exploring resources Ability. Their land.”

He added: “The importance of this scientific discovery lies in increasing the biodiversity inventory of organisms, especially in the United Arab Emirates. This adds to the value of protecting wetland ecosystems as an important resource for protecting the planet’s environment and organisms.”

Researchers have discovered a new microbe in the deserts of the Arabian Peninsula. The discovery helps answer some questions about the history of these daphnia in the northern hemisphere and track the spread of these microbes in North Africa and the Middle East. The team studied the distribution patterns of biodiversity and its formation history in continental waters. Most scientific publications on this genus are related to this subgenus, without similar studies on microorganisms living mainly in temporary water bodies.

Professor Waleed Hamza noted, “We have successfully identified the creature, identified it as a new species, and named it “Daphnia arabica sp. nov,” referring to its presence in the Arabian Peninsula, and will It is distinct from other species and belongs to another group, living mainly in temporary freshwater bodies.The researchers collected core samples of dry sediments behind the Shuwaib Dam (Al Ain City) in March 2018.

The sediment was soaked in drinking water for three weeks, the eggs encased in the sediment hatched, and the decomposed organisms were isolated and cultured in the Marine Biology Laboratory of the Faculty of Science at the United Arab Emirates University with the help of the Khalifa Centre. Genetic Engineering and Biotechnology and Russian Academy of Sciences in Moscow. In-depth micromorphological, molecular (DNA) and further genomic and morphological analyses of isolated organisms were performed using modern “transparent cameras”.
