Write Out the Per Capita Income of 5 Developed and 5 Developing Countries Over the Past 5 Years

ASSIGNMENTWrite out the per capita income of 5 developed and 5 developing countries over the past 5 years.---The primary factor used to distinguish developed countries from developing countries is the Gross Domestic Product (GDP). Per capita is the tally of all the goods and services produced in a country in one year, expressed in U.S. dollars. GDP is calculated by dividing a country’s GDP by its population. For example, a small country with a GDP of $1 billion and a population of 50,000 h...

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...
