Random Chromosome Breakage By Colchicine Inviscum Fischeri (Loranthaceae)
(University of Nairobi, 1978)
When the shoot-tips ofViscum fischeri Engl. were treated with various concentrations of colchicine for different lengths of time, it was found that in this plant chromosome breakage was not localized to centromeric region ...
A Radio-telemetry Technique For Monitoring Temperatures From Unrestrained Ungulates
(University of Nairobi, 1970-10)
Miniature radio transmitters were used to monitor deep muscle, subcutaneous, skin surface,
and hair stlrface temperatures in three species of unrestrained African ungulates. Deep muscle and
suboutaneous transmitters were ...
Environmental aspects of settlement site decisions among pastoral Maasai
(University of Nairobi, 1979)
Maasai settlements in Amboseli are distributed in a pattern which reflects various physical and biological characteristics of the landscape. The settlements avoid hillslope gradients exceeding 0.08, and the lower sections ...
Inhibition By Tryptophan Of Nucleolar Rna Synthesis In Salivary Gland Nuclei Of Chironomus Thummi
(University of Nairobi, 1979)
Tryptophan, but not glutamine and lysine, inhibits the incorporation of3H-uridine into nucleoli of explanted salivary glands by about 60%. In isolated nuclei also, the nucleolar incorporation of3H-uridine triphosphate is ...
Gliding Flight Of The White-backed Vulture Gyps Africanus
(University of Nairobi, 1970-11)
1. Glide-comparison measurements were made on ten species of East African soaring birds using a Schleicher ASK-14 powered sailplane. Horizontal and vertical speed differences between bird and glider were measured by a ...
Gliding Flight of the Dog-Faced Bat Rousettus Aegyptiacus Observed in a Wind Tunnel
(University of Nairobi, 1971)
1. A bat was trained to fly in a tilting wind tunnel. Stereoscopic photographs were taken, both by reflected and by transmitted light, and measurements of best gliding angle were made.
2. Variation of wing span and area ...
New Perspectives In Vertebrate Paleoecology From A Recent Bone Assemblage
(University of Nairobi, 1979)
Abstract.-Interpretations of vertebrate paleoecology depend on knowledge of taphonomical processes which alter the composition of the preserved fossil assemblage from that of the original community. Study of the potential ...
Structure and fine structure of the hypophyseal pars distalis in endigenous African species of the genus Tilapia
(University of Nairobi, 1974)
The structure and fine structure of the pars distalis hypophyseos was examined in five species of Tilapia fishes (T. alcalica, T. grahami, T. leucosticta, T. zillii, T. nigra) which were collected from lakes of a wide range ...
