    The syntax and semantics of causative affixes in central Kenya Bantu

    Item type: Journal Article • Journal: South African Journal of African Languages
    Typologists have established that there are two main types of causative constructions: the lexical and the non-lexical (Cooper, 1976; Shibatani, 1973, 1976; Givon, 1976). The two constructions are said to differ both syntactically and semantically. One of the main syntactic...
  2. Nesting status of African White-backed Vultures <em>Gyps africanus</em> in the Masai Mara National Reserve, Kenya

    Nesting status of African White-backed Vultures <em>Gyps africanus</em> in the Masai Mara National Reserve, Kenya

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Vulture populations have declined globally as well as regionally within Africa. Little is known about the status of the African White-backed Vulture Gyps africanus in Kenya, but ongoing studies indicate that its population has declined over the last two decades...
  3. Vegetation composition and structure influences bird species community assemblages in the highland agricultural landscape of Nyandarua, Kenya

    Vegetation composition and structure influences bird species community assemblages in the highland agricultural landscape of Nyandarua, Kenya

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    We examined the effects of vegetation composition and structure on bird species diversity and richness of foraging guilds in the highland agricultural landscape of Nyandarua, Kenya. Bird point counts and vegetation surveys were undertaken during four sampling periods. Linear mixed...
  4. Bird species richness and abundance in different forest types at Kakamega Forest, western Kenya

    Bird species richness and abundance in different forest types at Kakamega Forest, western Kenya

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The avifauna of differently disturbed forest types of Kakamega Afrotropical forest were compared from December 2004 to May 2005. A total of 11 220 individual birds comprising of 129 bird species were recorded. Significant differences in abundance of birds among...
  5. Experimental evidence of 'floaters' in two isolated populations of an Afrotropical forest bird

    Experimental evidence of 'floaters' in two isolated populations of an Afrotropical forest bird

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    We studied the presence of 'floaters', i.e. non-territorial individuals roaming occupied territories awaiting future breeding opportunities, in two separate White-starred Robin (Pogonocichla stellata) populations at the Taita Hills, Kenya, using a removal experiment. Previous vegetation analyses at this site had...
  6. Confinement lowers fertility rate of helmeted guinea fowl (<em>Numida meleagris</em>) eggs

    Confinement lowers fertility rate of helmeted guinea fowl (<em>Numida meleagris</em>) eggs

    Item type: Journal Article • Journal: African Zoology
    Guinea fowl is a common game bird in Africa and there have been efforts to domesticate it for use as a source of human food. An important obstacle in successful domestication of guinea fowl is their low fertility rate.We studied...
  7. Crop Yield Response to Incorporation of Leaf Prunings in Sole and Alley Cropping Systems

    Crop Yield Response to Incorporation of Leaf Prunings in Sole and Alley Cropping Systems

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    This experiment assessed the feasibility of using leaf prunings of Calliandra calothyrsus and Leucaena leucocephala for soil fertility improvement in alley cropping and sole cropping systems. The experiment, conducted at the National Agroforestry Research site at the Kenya Agricultural Research...
