    Host specificity, prevalence and intensity of infestation of fleas (Order Siphonaptera) of small mammals at selected sites in the city of Windhoek, Namibia
    (University of Namibia, 2013) Mfune, John K.; Kangombe, Fransiska; Eiseb, Seth J.
    Small mammals host diverse communities of parasites including fleas. There is considerable research interest in effects of parasites on their hosts. Host specificity, prevalence and intensity of infestation of fleas on small mammals were studied at selected sites in the city of Windhoek, Namibia from April to July 2005. Small mammals were live-trapped using Sherman traps and autopsied before collection of fleas. Fleas were processed using standard parasitological procedures and were mounted permanently onto slides using Canada balsam. Small mammal hosts and fleas were identified to species level. A total of sixty one (61) small mammals belonging to four rodent species, i.e. bushveld gerbil Gerbilliscus leucogaster, hairy-footed gerbil Gerbillurus paeba, black-tailed tree rat Thallomys nigricauda and the four-stripped mouse Rhabdomys pumilio and one insectivore, bushveld sengi Elephantulus intufi, were captured. One hundred and thirty six (136) fleas belonging to eight species, i.e. Xenopsylla brasiliensis, Xenopsylla cheopis, Xenopsylla hirsuta, Xenopsylla trispinis, Dinopsyllus ellobius, Dinopsyllus zuluensis, Epirimia aganipes and Listropsylla aricinae were collected from infested hosts. Dinopsyllus ellobius and X. trispinis and L. aricinae were host specific, being collected only from G. leucogaster and G. paeba, respectively. No fleas were collected from E. intifi and R. pumilio. The prevalence of fleas ranged from zero in E. entufi and R. pumilio through 50 % in T. nigricauda, 55.1% in G. leucogaster to 61.1% in G. paeba. High species richness of fleas was recorded in G. leucogaster (seven out of eight flea species) and in G. paeba (six out of eight flea species). The overall prevalence of fleas was higher in male (54.3%) than in female (34.6%) hosts. There was no association between the body mass of small mammal hosts and the intensity of flea infestation. The intensity of infestation of fleas did not vary significantly by host species and sex of hosts.

    International joint MSC Programme: University of Namibia and Humboldt University, Germany
    (University of Namibia, 2013) Mfune, John K.
    The MSc Biodiversity Management and Research Programme is a full time interdisciplinary and international postgraduate programme jointly run by the University of Namibia (Department of Biological Sciences, Faculty of Science) and Humboldt-Universitt zu Berlin, Germany. The main goal of the program is to build capacity to increase the number of postgraduate local and regional experts in the field of Biodiversity Management and Research. This program was designed to ”Build capacity to manage biodiversity and sustainable development in Namibia” as incorporated in Namibia governments ten-year strategic plan of action for sustainable development through biodiversity conservation (National Biodiversity Strategy and Action Plan, 2001-2010). During the programme, students gain in-depth knowledge of natural-spatial features and biological diversity in Southern Africa with emphasis on Namibia, understand ecosystem functioning and human-induced impacts and the economic values and importance of biodiversity. Students also acquire skills that will enable them to design and undertake research to solve practical, relevant problems to society, using scientific methods and techniques. Graduates of the programme are employable in any biodiversity conservation and related fields including but not limited to lecturing, working for the Ministry of Environment and Tourism (National Parks, Scientific Services, Tourism), ecotourism, curators of various taxa at Natural History museums, and community based organizations. Our graduates contribute to management of natural resources, conservation and sustainable use of biodiversity and also contribute to poverty reduction through use of natural resources to improve livelihoods of local people.
