Surveillance of Avian influenza Viruses in Wild Ducks and Geese in the Bangweulu Wetlands of Zambia
University of Zambia Journal of Agricultural and Biomedical Sciences, 2012Avian influenza is a highly contagious acute respiratory disease of avian origin and is of major economic and public health importance. Out of all the 16 haemagglutinin subtypes of influenza viruses, only H5 and H7 are considered highly pathogenic in poultry.

Climate variability and climate change have negative impacts on fisheries ecosystems and people who derive livelihoods from them. Zambian climate is projected to increase 2 °C in mean temperature by 2070, and further reports suggest that rainfall will drop by 8-30% of the normal average.

Growth of the Cichlid Fish Tylochromis bangwelensis in Lake Bangweulu, Zambia
Transactions of the American Fisheries Society, 1977Abstract Growth of the cichlid Tylochromis bangwelensis was assessed by examination of scales from fish collected in Lake Bangweulu, Zambia, in 1972–1973. Discontinuities in circuli that appeared to be valid annuli were observed. They appeared on scales of yearling fish in August-October and on scales of older fish slightly later, apparently in ...

Annulus Formation and Growth of Tigerfish, Hydrocynus vittatus, in Lake Bangweulu, Zambia
Transactions of the American Fisheries Society, 1975Abstract The validity of scale analysis for aging tigerfish, Hydrocynus vittatus Castelnau, was assessed by examining the timing and cause of check formation on scales from fish collected in Lake Bangweulu, Zambia. Discontinuities in circuli that appeared to be valid annuli formed on all scales in September when water temperature was rising rapidly ...

Ostrich, 1984
Summary Howard, G. W. & Aspinwall, D. R. 1984. Aerial censuses of Shoebills, Saddlebilled Storks and Wattled Cranes at the Bangweulu Swamps and Kafue Flats, Zambia. Ostrich 55: 207–212. Aerial counts of three wetland species of uncertain conservation status were made in Zambia when the opportunity arose during Lechwe Kobus leche censuses.

Linguistic syncopations of the Kalela dance – Riding the waves of Lake Bangweulu of Zambia
Muziki, 2007ABSTRACT Research on the Kalela dance of Zambia has tended to focus on the dance as performed in urban Zambia, especially the Copperbelt. While it is true that this dance is popular in urban areas, this article argues that casting this dance as an urban dance has robbed the public a chance to sample the richness of its roots.

Fisheries Management and Ecology, 1998
The feasibility of participation by local fishermen in scientific fisheries data collection for stock assessment is described. Artisanal fishermen from the Bangweulu Swamps, Zambia, collected length‐frequency data for 1 year from their catch using the main fishing methods employed in the swamps as well as experimental gears.

SummaryObservations made through almost the whole of one breeding season are summarized. Although scientific observations were secondary to making a television film, many new data were gathered.The breeding season occupies 140–145 days from nestbuilding to loss of contact with the young.

Abstract. Shoebills (Balaeniceps rex) breed in central-eastern Africa with a world population of only 5,000-8,000 individuals. To provide protection to this threatened species, conservationists need a better understanding about Shoebill foraging and breeding ecology, their habitat use and their distribution.
