There is therefore a great need to conserve this speciesto ensure it does not become extinct. This study evaluated regeneration potential of the Africancherry, identified the appropriate stage of collecting seeds for propagation and suitable sowingmedia that gives optimum germination and sought to identify other tree species with potentialco...

Spatio-Temporal Changes In Land Cover In Response To Anthropogenic And Hydrodynamic Factors In Nyando Wetland, Kenya

ABSTRACTIn the last three decades, wetlands have received much attention worldwide due to their declining coverage and spatial distribution with more than 50% lost since the 1950s. Like other wetlands worldwide, Nyando Wetland, the second largest lacustrine wetland ecosystem on the Kenyan shores of Lake Victoria, is facing a major threat of degradation from both the fluctuations of Lake Victoria water levels and anthropogenic factors operating in its neighbourhoods. This study was conducted t...

Population Dynamics And Feeding Ecology Of The Black Rhino (Diceros Bicornis) In Ngorongoro Conservation Area, Tanzania

Africa was once known for abundant populations of the now Critically Endangered Black rhino (Diceros bicornis). However, large-scale poaching in many parts of this continent during 1970- 1980 led to a 95% decline in the rhino numbers. Like in other countries that host remnant populations of the Black rhino, Tanzania’s Black rhinos are now largely restricted to protected areas such as the Ngorongoro Conservation Area (NCA). This study sought to map the spatial distri...

Influence Of Grazing Intensity On Cyanogenic Toxicity In Savanna Grasses In Baringo, Keny

The potential role of anti-herbivory mechanisms involving use of qualitative and quantitative compounds in minimizing herbivory is well known. However, synergistic responses to grazing and interactive effects on herbivores are poorly understood. The aim of this study was to quantify the interaction between cyanogenic glycosides in grasses with cattle grazing in Lake Bogoria (00°28'N, 35°59'E), Baringo County. Field experiments were carried out in ten 50×10m exclosures&n...

An Analysis Of Hotel Rating And Its Implication On Financial Turnover Of Rated Hotels In Kenya

Hotel service quality has long been a concern for scholars and practitioners. Previous researches indicate that the service quality of hotels in Kenya is yet to match international standards. It has been argued that one reason why hotels do not deliver quality service is due to the substantial gap of the living standards of Kenyans and international tourists and the lack of proper investment in the sector due to fluctuations in growth in the past. With the recent growth in...
