(University of Nairobi, 1971)Geological evidence makes possible a reconstruction of events since Miocene times, with about 10 km of crustal separation and the pressure beneath the central rift of an upward intrusion from the mantle. -
Exploring Below Ground Complementarity In Agroforestry Using Sap Flow And Root Fractal Techniques
(University of Nairobi, 1998-11)Indices of shallow rootedness and fractal methods of root system study were combined with sapflow monitoring to determine whether these ‘short-cut’ methods could be used to predict tree competition with crops and complementarity ... -
Confinement Lowers Fertility Rate of Helmeted Guinea Fowl (Numida meleagris) Eggs
(University of Nairobi, 2014)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 ... -
