The interspecific relationships of Juncus effusus and J. conglomeratus in Britain
(University of Nairobi, 1968)Juncus effusus and J. conglomeratus appear to be specifically distinct in the British Isles; J. conglomeratus is the rarer species. Their principal diagnostic features are given. Evidence is presented to show that the ... -

Observations on the changing vegetation of Tsavo National Park (East)
(University of Nairobi, 1968-08)An analysis of woody vegetation in Tsavo National Park (East) by extensive variable-plot sampling indicates that the vegetation had been differentially destroyed up to 1966, but that by 1967 considerable local shrub ... -
The use of game trails as a possible measure of habitat utilisation by larger mammals
(University of Nairobi, 2008)Percentage cover of game trails is discussed as a possible measure of total habitat utilisation by larger mammals and a technique for its measurement is described. Game trail cover in Tsavo National Park (East) at Voi has ... -
Magnetic Grains in Bombay Columnar Basalts
(University of Nairobi, 1971-11)THE origin of columnar jointing in basalt has been discussed by several authors1, but the origin of many features of the columnar basalts is still controversial. Some magnetic studies of individual columns have been made ... -
Field and laboratory methods for research into the anatomy of east African Game animals
(University of Nairobi, 1966)Descriptions are given of various methods which have been used in the field and in the laboratory to obtain and investigate specimens for comparative studies of the anatomy of East African game animals. Fixation of the ... -
On sociology and behaviour in impala (aepyceros (melampus lichtenstein)
(University of Nairobi, 1966-08)1. The required habitat of impala, association with other herbivores and the relation to predators are outlined. 2. The commonest types of group formation - female herd with dominant male and bachelor herd - and the ... -
The giraffe of Nairobi National Park: home range, sex ratios, the herd, and food
(University of Nairobi, 1966)The giraffe of Nairobi National Park, Kenya have been studied for one year. Each animal seen has been photographed from the left side and the pattern on the neck used to recognize each individual. While the pattern may ... -
A Review of Some Methods Used in Determining Actual Evapotranspiration in East Africa
(University of Nairobi, 1979)A brief review of some of the methods used in East Africa for determining actual evapotranspiration/evaporation is presented. The methods reviewed include: empirical methods, atmospheric water balance method, and the ... -
The influence of weather on asthma in Nairobi
(University of Nairobi, 1978)The frequency of bronchial asthma in Nairobi is related to meteorological parameters such as relative humidity, rainfall, dew point temperature, hours of sunshine and dry bulb temperature. Two seasons were taken for study: ... -
An observational study of 300 mb winds in the tropical belt. Part II: Dynamical interpretation
(University of Nairobi, 1983)An observational study of 300 mb winds in the tropical belt. Part II: Dynamical interpretation -
An observational study of 300 mb winds in the tropical belt. Part I: Kinematic parameters
(University of Nairobi, 1983)This study is diagnostic in character and entails a systematic investigation of the kinematic parameters of the mean monthly 300 mb horizontal-motion field for the global tropical region during January, April, and ... -
Pressure wind adjustment relationships during dynamic initialization process with tropical wind data
(University of Nairobi, 1978)In an attempt to understand the kind of balance the initially imbalanced low latitude mass and motion fields tend to adjust to during an iterative dynamic initialization process we carry out a systematic investigation of ... -
Evaporation values in East Africa
(University of Nairobi, 1981)Potential evaporation (E p) and actual evapotranspiration (E A) values for 84 East African stations were estimated and mapped using Morton [12, 13, 14] model. The data used in the study were long term averages up to and ... -
Some aspects of dynamic initialization using real tropical wind data
(University of Nairobi, 1977)In this study an iterative initialization scheme suitable for tropical regions is designed, tested and used as an initialization vehicle in an experiment involving real tropical data. The model equations for the initialization ... -
Reciprocal allogrooming in impala, Aepyceros melampus
(University of Nairobi, 1992-12)Adult female and male impala engage in a type of allogrooming in which partners alternately deliver bouts of oral grooming to the head and neck. These grooming encounters comprise typically six to 12 tit-for-tat-like ... -
Water availability and its influence on the structure and dynamics of a savannah large mammal community
(University of Nairobi, 1975-12)The Amboseli ecosystem is in a semi-arid savannah environment in which water availability is highly seasonal, a feature which has an important bearing on the structure and efficiency of the large mammal community. Data ... -
Size, life history and ecology in mammals
(University of Nairobi, 1979-12)Allometric laws which scale numerous biomechanical and physiological processes to size in mammals have long been recognized and widely used in biology. There is now sufficient evidence to suggest that those life history ... -
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 ...
