Thermoregulation and metabolism in a small desert carnivore: the Fennec fox (Fennecus zerda) (Mammalia)†
(2009-08-20)
In controlled laboratory experiments the effects of ambient temperatures on thermoregulation, metabolism, heat balance, heart rate, and total evaporative water loss were studied in the Fennce fox (Fenneus Zerda) from the ...
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 ...
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 ...

A comparison of digestion in red deer and sheep under controlled conditions
(University of Nairobi, 1971-11)
Three red deer hinds and three sheep were given rations of chopped or pelleted hays. The deer apparently digested dry matter and cellulose a little less well than the sheep. Digestibility of nitrogen did not differ.
In ...
Temperature regulation in the somali donkey (Equus asinus).
(University of Nairobi, 1978-08)
In controlled laboratory experiments the metabolic rate, body temperature, respiratory, sweat and heart rates were measured in adult donkeys weighing between 125 and 180 kg.At high ambient temperatures Ta (40–50°C) the ...
Mechanics of running of the ostrich (Struthio camelus)
(University of Nairobi, 2009-08-20)
Ostriches have been filmed running fast in their natural habitat. A female ostrich has been dissected and the principal bones, muscles and tendons in a leg have been measured. It is calculated that stresses up to 240 kN ...
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 ...
Organic acid concentrations and digesta movement in the gastrointestinal tract of the bushbaby (Galago crassicaudatus) and Vervet monkey (Cercopithecidae pygerythrus)
(University of Nairobi, 2009-08)
Studies were conducted to compare digestive functions in two species of sub-human primate, the bushbaby (Galago crassicaudatus) and the Vervet monkey (Cercopithecidae pygerythrus). Major differences were observed in the ...
