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. ...
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 ...
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 ...
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, ...
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, ...
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. ...
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 ...

Effect of gibberellic acid (GA3) and temperature on seed germination of Rauvolfia serpentina
(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 ...
