Changes in thyroxine, triiodothyronine and metabolic rate in the dik-dik antelope (Rhynchotragus kirkii): effects of temperature and dehydration
(University of Nairobi, 1983-02)
Changes in plasma total thyroxine, triiodothyronine (T3) and metabolic rate were investigated in both hydrated and dehydrated dik-diks after prolonged exposure to ambient..
Transpiratory water loss and metabolism of beetles from arid areas in East Africa
(1987)
. Carabid beetles have rates of transpiratory water loss and metabolic rates which are higher than those of tenebrionid beetles. Within each family, dry habitat beetles have lower rates of water loss than beetles from mesic ...
Temperature insensitive O2 in blood of the tree frogChiromantis petersi
(Springer-Verlag, 1980)
Respiratory gas exchange and blood respiratory properties have been studied in the East-African tree frogChiromantis petersi. This frog is unusually xerophilous, occupies dry habitats and prefers body temperatures near ...
The mechanism of intracardiac shunting in the lizard Varanus exanthematicus.
(1983-07)
Intracardiac shunting was studied in unanaesthetized and unrestrained specimens of Varanus exanthematicus by simultaneous injection of radioactively labelled microspheres (15 micron) into the right and left atria. Lung ...
Respiration and metabolism in the giraffe.
(1982-11)
Measurements have been made on respiration of three resting unstressed adult giraffe under normal conditions. Tracheal dimensions and body dimensions have also been measured in a large number of giraffe and other mammals. ...
Digestive physiology of East African wild ruminants.
(1983)
The physiology of digestion of wild ruminants in their natural habitat was determined. The study consisted of fifty-one adult male animals representing sixteen species. While diet and body weight were both related to the ...
An ultrastructural and histochemical study of the axial musculature in the African lungfish.
(Springer-Verlag., 1981)
Red, intermediate, and white axial muscle fibres of African lungfish were studied using histochemical techniques and electron microscopy. Gross dissection revealed the presence of a small wedge of red coloured muscle along ...
Design of the mammalian respiratory system. V. Scaling morphometric pulmonary diffusing capacity to body mass: wild and domestic mammals.
(1981-04)
This paper utilizes a comparative approach to establish the relationship between morphometric diffusing capacity for oxygen (DLo2) and maximal oxygen consumption (Vo2max). DLo2 and Vo2max were determined on the same 21 ...
Colonic absorption and secretion of electrolytes as seen in five species of East African herbivorous mammals
(University of Nairobi, 1980)
1. The camel, sheep, goat and donkey were equally efficient in recovering fluids from colonic contents. Zebu cattle were the least efficient.
2. Compared to other species, Zebu cattle demonstrated a reduced sodium and ...
