Temporal patterns of duetting in African barbets
(1970)Four species of African barbets (Lybius torquatus, L. vieilloti, Trachyphonus darnaudii, and T. erythrocephalus) regularly sing in duet. Duets consist of phrases repeated at very regular intervals; in L. torquatus and L. ... -
Plant Dispersal by Hares (Lepus Capensis L.) in Kenya
(University of Nairobi,, 1970)Of 369 hares examined, 160 had a total of 810 disseminules of 17 plant species in their fur. The six commonest plants were Tragus berteronianus, Achyranthes aspera, Pupalia lappacea, Boerhavia repense, Harpachne schimperi, ... -

Effect of gibberellic acid (GA3) and temperature on seed germination of Rauvolfia serpentina
(College of Biological Sciences, University of Nairobi, 1970)GA was applied at 250, 500, 750 or 1000 mg/l. The 500-mg level in the laboratory increased germination from 5 (control) to 45.2%, and survival from 2 to 25.7%. Under field conditions the comparable figures for germination ... -
The palaeomagnetism of the Ethiopian flood basalt succession near Addis Ababa
(University of Nairobi, 1970-01-22)Measurements on samples from 20 sites in the Ethiopian flood basalt succession yield a palaeomagnetic pole at 80.8° N, 167.7° E with a circle of confidence of 4.3°. The pole for these rocks is significantly different from ... -
A method of identifying individual lions Panthera leo with an analysis of the reliability of identification
(University of Nairobi, 1970-04)A method is described of identifying lions from the patterns of vibrissa spots. “Reliability” of identification is discussed in terms of the probability of there being more than one individual with a given spot pattern in ... -
Some properties of ionospheric irregularities as deduced from recordings of the San Marco II and BE-B satellites
(University of Nairobi, 1970-07)Recordings of scintillations on signals received at Nairobi from satellites San Marco II and BE-B have been analysed by correlation and dispersion methods, the correlation method equations being derived in a simpler way. ... -
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 ... -
Effect of chorionic gonadotrophin on testicular histology and testosterone production in Tilapia leucosticta (Teleostei: Cichlidae
(University of Nairobi, 1970-10)Eight adult male T. leucosticta were given daily injections of 500 IU human chorionic gonadotrophin (Pregnyl, Organon) intraperitoneally for 1 week. These fish showed marked increases in testicular size, gonosomatic index, ... -
Control of gliding angle in Rüppell's Griffon Vulture Gyps rüppellii
(University of Nairobi, 1970-11)1. The drag of the frozen, wingless body of a Rüppell's griffon vulture was measured in a wind tunnel with a simple drag balance. The drag coefficient with feet and neck retracted was 0.43, based on the greatest cross-sectional ... -
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 ... -
Scintillation fading of signals in the SHF band
(University of Nairobi, 1971)IN September 1970, the Mount Longonot satellite telecommunication station, situated in the Rift Valley thirty miles north-west of Nairobi, was put into commercial operation by the East African External Telecommunication ... -

Effect of Atrazine on Physiological Processes in Leaves
(University of Nairobi, 1971)We fed 2-chloro-4-(ethylamino)-6-(isopropylamino-s-triazine (atrazine) through the base of excised leaves of atrazine-tolerant and -susceptible species. Atrazine suppressed CO2 uptake in all species. This was shown to be ...
