Effect Of Anthropogenic Activities On Degradation Of Lake Shores; A Case Of Lake Babati

ABSTRACTThe sustainability of many lake ecosystems in the world including Lake Babati is threatened by the ongoing degradation due to anthropogenic activities. A study was carried out to assess the effect of anthropogenic activities on the degradation of Lake Babati shores based on specific objectives: (1) to identify institutions and institutional arrangements responsible on the management of lake ecosystem, (2) to identify drivers leading to the lake shores degradation, (3) to assess t...

Sustainable Management Of Harpagophytum Procumbens And The Effect Of Effective Micro-Organisms And Sulphuric Acid On Its Seed Germination

AbstractDevil’s claw (Harpagophytum procumbens) is a geophyte that occurs mainly in Central,East and South eastern Namibia where it was previously regarded as a nuisance due to itsfruit-claws getting caught on sheep and other livestock. The species has been exploiteddue to its medicinal properties leading to concerns regarding its sustainability. Efforts toconserve it have been tried in order to understand conditions suitable for its managementbut there are still poor results in the germina...

Effects Of Environmental Variability On Fish Diversity And Composition Along The Southern Namibian Coastline During Summer

ABSTRACTSpecies diversity, richness and composition of fish in bottom-trawling were investigatedoff the Namibian coast between Oranjemund and Henties Bay. Sampling followed asystematic transects design, along latitude gradients (28-22oS) at different seafloordepths (100-500m). In total 18 transects were sampled containing 105 stations. At eachtrawled station the whole catch was sorted into species type and the total body mass (kg)of each fish species was recorded. A total of 91 fish species w...

Impact Of Mine Pollution On Composition, Diversity And Structure Of Plant And Ground-Dwelling Invertebrate Communities Around Kombat Mine Tailings Dump, Namibia

ABSTRACTThe impact of heavy metal pollution on vegetation and communities of ground-dwelling invertebrates was investigated at Kombat Mine tailings dump in Namibia. Sixteen transect lines were marked around the dump. Plots, 15m x 15m, were marked at 50m intervals along each transect. Top soils in the demarcated plots were sampled and analysed for concentrations of heavy metals and total sulphur. Woody plant species were identified, counted and heights measured. Herbaceous plants were identifi...

Genetic Diversity Of Sorghum (Sorghum Bicolor (L.) Moench) And Its Wild Relatives In Namibia Using Ssr And Rapd Analyses

ABSTRACTSorghum bicolor (L.) Moench is the fifth most important cereal crop in the world, and in Namibia, sorghum is the second most important. The genetic resources of sorghum remain unexplored in Namibia. This could lead to a loss of genetic diversity as wild relatives and foreign varieties could interbreed with landraces, resulting in an undesired alteration of its genetic make-up. This study was conducted to evaluate the genetic diversity among the Namibian Sorghum bicolor accessions stor...

Seasonal Occurrence Of Fleas And Other Ectoparasites On Small Mammals At Waterberg Plateau Park, Namibia

ABSTRACTFleas and other ectoparasites infesting small mammals were studied from December 2005 to June 2006 at Waterberg Plateau Park, Namibia. The main aim of this study was to investigate seasonal occurrence of fleas and other ectoparasites on small mammals at selected sites at Waterberg Plateau Park. Small mammals were live-trapped, marked and released. Ectoparasites were collected (by brushing) from these small mammals before they were marked and released. Fleas, ticks and lice were stored...

Abundance, Structure And Uses Of Baobab (Adansonia Digitata L.) Populations In Omusati Region, Namibia

ABSTRACTThis study sought to determine the biology and the uses of baobab (Adansonia digitata L.) populations in Outapi and Onesi constituencies in Omusati Region, Namibia. As one of the important Non-Timber Forest Products (NTFPs)-providing species of ecological and socio-economic significance, there is need to have a better understanding of the biology and local uses of the species before its full potential and sustainable harvesting is realized. A comparison of densities, distribution patt...

The Influence Of Land Use On Plant Species Diversity In The Biosphere Area “Schwäbische Alb”, Southwest Germany

AbstractThe aim of this study was to determine the relations between the intensity of landuse and the characteristics of different habitat types within the grasslandecosystem in the Biosphere Area “Schwäbische Alb” in Germany. Data has beencollected based on 50 examination plots (4×4 m) of the BiodiversityExploratories project. These plots represented different land use types and levelsof intensity which are 1) grazed, ungrazed 2) once, twice, three times mowed, 3)fertilised, unfertilis...

Age Determination And Growth Rate Of The Northern Benguela Sardine (Sardinops Sagax)

AbstractThe main objective of this study was to determine sardine age by counting rings on otoliths and to analyse the length, age and growth through regression and Von Bertalanffy Growth models. Otoliths amounting to 826 pairs were collected from the annual sardine research survey of the Ministry of Fisheries and Marine Resources in October 2013. A total of 713 sardine otoliths were mounted on black Perspex plates and aged by means of counting rings using a Zeiss microscope at a magnificatio...

Assessing Grevy's Zebra (Equus Grevyi) And Livestock Interactions Through Satellite Tracking And Community Involvement In Samburu County (Kenya).

AbstractThe study's purpose was to delineate seasonal space use variations of theendangered Grevy's zebra (Equus grevyi), and to determine the extent ofoverlap of these areas with livestock grazing zones in order to identify coreareas suitable for conservation efforts. E. grevyi requires protection as theirpopulation size severely decreased in the last century and they continue tosuffer from habitat loss. Additional importance lies in reconciling interests ofwildlife protection and livestock ...

Impact Of The Tsumeb Smelter Waste On Plant Species Diversity And Structure In Tsumeb, North-Central Namibia.

ABSTRACTThe objective of this study was to determine the impact of the smelter waste on plant species diversity and structure in the Tsumeb area. The most important sources of contamination are solid and gaseous emissions from the Tsumeb Smelter, airborne particles from the Tsumeb tailings pond and airborne particles from slag mill waste. Six sites: Inside Smelter Site, Outside Smelter Site, Abattoir Hill Site, Transnamib Site, Nomtsoub Site and Airport Site were selected and ten 10 m x 10 m ...
