Scanning electron microscope study of the morphology of the reptilian lung: the Savanna monitor lizard Varanus exanthematicus and the pancake tortoise Malacochersus tornieri.
(1989)
The morphology of the lungs of two reptilian species, Varanus exanthematicus and Malacochersus tornieri, have been studied on gross preparations, latex casts, and critical-point-dried tissues. The shape of these lungs was ...
Adaptations of Carabid Beetles to Dry Habitats in East Africa
(1986)
The rates of water loss and humidity preference of carabids from dry tropical habitats have been studied and compared with corresponding data from temperate carabids and tropical tenebrionids. Within each group of beetles ...
Energetics and mechanics of terrestrial locomotion. I. Metabolic energy consumption as a function of speed and body size in birds and mammals.
(1982-04)
This series of four papers investigates the link between the energetics and the mechanics of terrestrial locomotion. Two experimental variables are used throughout the study: speed and body size. Mass-specific metabolic ...
Physiology of the dik-dik antelope.
(1988)
1. The East African dik-dik antelope represents a miniature model ruminant for comparative studies. 2. Dik-diks are browsers, consuming a diet consistently high in fermentable and digestable plant material. 3. Their foregut ...
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 ...
The design and the role of the nasal passages in temperature regulation in the dik-dik antelope (Rhynchotragus kirkii) with observations on the carotid rete.
(1984-05)
xhaled air temperatures (Tex) and rectal temperatures (Trec) were measured in five dik-dik antelopes under controlled environmental temperatures (Ta) between 15 and 40 degrees C. In addition morphometric analysis of the ...
The effects of dehydration on electrolyte concentrations and water content along the large intestine of a small ruminant: The Dik-dik antelope
(University of Nairobi, 1980-05)
The concentrations of Na, K, and Cl and the water content in the large intestine and rectum of an East African ruminant, the Dik-dik antelope, was investigated in hydrated and dehydrated animals.
Intestinal contents were ...
Ionic content of body fluids and sodium efflux in Oreochromis alcalicus grahami, a fish living at temperatures above 30°C and in conditions of extreme alkalinity
(Elsevier, 1984)
1. Values for blood plasma ions at 35°C are: Na, 210.4 ± 4.6; Cl, 144.6 ± 2.6 and K, 6.5 ± 0.4 mM; osmotic pressure, 400 ± 18 mOsm.
2.
2. Blood ionic composition resembles that of marine teleost species except that at ...
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 ...
