Renal function and electrolyte balance during dehydration in the hyrax
(University of Nairobi, 1976-09)
The rock hyrax has been shown to have a very unusual and complex digestive tract. The gastrointestinal tract is comparable to that of the simple and complex stomach of mammals as well as to that of birds. Determinations ...
Nutrient digestibility and gastrointestinal electrolyte flux in the elephant and rhinoceros
(1983)
Nutrient digestibility and absorption-secretion were studied in elephants and rhinoceros.
2. Prehension and diet selection are discussed.
3. Rhinoceros select less fiber, which may account for their greater digestive ...
Sodium balance in the catfish Clarias mossambicus exposed to acid water
(University of Nairobi, 1983-08)
African catfish, Clarias mossambicus showed no ill effects when kept in acid water pH 4–5 for 3–4 days. Their ionic regulatory response was examined and during 24 h exposure to water of pH 4, Na+ efflux increased significantly ...
Design of the mammalian respiratory system. II. Measuring maximum aerobic capacity.
(1981-04)
We describe a simple and reproducible procedure for measuring maximal O2 consumption (Vo2max) that can be used for mammals spanning a wide range of body mass (Mb). Vo2 of trained animals was measured as a function of speed ...
Studies on renal excretion of potassium in the dik-dik antelope.
(Elsevier Science Ltd, 1988)
1. In a study on the renal handling of potassium by the dik-dik antelope, plasma and urine samples were analysed for potassium, sodium and creatinine concentrations and osmolality during dehydration and intra-ruminal loading ...
The relationship between rate of oxygen consumption, heart rate and thermal conductance of the dik-dik antelope (Rhynchotragus kirkii) at various ambient temperatures.
(1982)
1. The extent of cardiovascular adjustments to heat and cold were investigated between ambient temperatures of 5 and 45 degrees C by measuring conductance and the rates of oxygen consumption and heart beats. 2. Minimum ...
Renal excretion of urea and electrolytes in sheep and red deer.
(1969-11)
1. The effects of varying the intake of water and nitrogen on the renal excretion of urea and electrolytes has been studied in sheep and in red deer.2. The concentration of urea in the urine of both sheep and deer decreased ...
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..
pH, Salinity and Temperature Tolerance of Lake Magadi Tilapia
(University of Nairobi, 1974-01)
THERE are several species of Tilapia isolated in the alkaline lakes of
the Great Rift Valley of Africa, living in extreme conditions of
temperature, salinity and pH. One of these fish, the Lake Magadi Tilapia
(Tilapia ...
