Professor Jo G. Van As and Dr Liesl L. Van As of the Dept. of Zoology and Entomology, University of the Free State, South Africa, visited HOORC's Library today with copies of published work from the last ten years of their research on fish parasites in the Okavango system. The Van As team is looking at the interactions among parasites and their hosts in the natural system of the Okavango, unlocking the fish parasite diversity. The team has identified more than 20 unicellular organisms, roundworms, flatworms, blood parasites and parasitic crustaceans, including many that are unique to the Okavango system. Their research is also contributing to graduate studies at the University of the Free State, the University of Johannesburg and the University of Limpopo. You can find the published work of the Van As team and associates in HOORC's Library.
