The effects of temperature on muscle pH, adenylate and phosphogen concentrations in Oreochromis alcalicus grahami, a fish adapted to an alkaline hot-spring
(Wiley, 1983)
The concentrations of phosphorylcreatine (PCr), adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), inorganic phosphate (Pi), pyruvate and lactate were determined in freeze-clamped ...
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 ...
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..
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 ...
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 ...
Molar proportions of volatile fatty acids in the gastrointestinal tract of East African wild ruminants.
(1983)
The molar proportions of seven individual VFA's were determined at select sites along the gastrointestinal tract of sixteen species of East African wild ruminants. The resulting data were statistically analyzed for species ...
A comparative study of basal metabolism and thermoregulation in a folivorous (Colobus guereza) and an omnivorous (Cercopithecus mitis) primate species.
(University of Nairobi, 1983-02)
1. Abdominal temperatures (Tab) and oxygen consumption (VO2) were measured in two males each of colobus and Sykes monkeys. 2. Tab in both species had the same range (36 38.5 C), but there were marked differences in the ...
Aquatic and Aerial Respiration Rates, Muscle Capillary Supply and Mitochondrial Volume Density in the Airbreathing Catfish (Clarias Mossambigus) Acclimated to Either Aerated or Hypoxic Water
(1983)
Specimens of the African air-breathing catfish Clarias mossambicus were acclimated to either aerated (PwO2 15.3 KPa) or hypoxic (PwO2 2.4KPa) water for up to 27 days at 20 °C. Routine respiration rate for fish acclimated ...
