Mechanical stresses in fast locomotion of buffalo (Syncews coffer) and elephant (Loxodonta africana)
(University of Nairobi, 2009-08-20)
Films of buffalo and elephant running, and detailed measurements on dissected legs, have been used to estimate the maximum stresses which occur in locomotion, in certain muscles, tendons and bones. These stresses are similar ...
Allometry of the legs of running birds
(University of Nairobi, 2009-08-20)
The principal bones, muscles and tendons of the legs have been measured in a selection of running birds, ranging in size from 0–1 kg quail to 40 kg ostrich. Maximum stride frequencies of the same species have been determined ...
Activation of micro, delta or kappa opioid receptors by DAMGO, DPDPE, U-50488 or U-69593 respectively causes antinociception in the formalin test in the naked mole-rat (Heterocephalus glaber).
(University of Nairobi., 2009-02)
Data available on the role of the opioid systems of the naked mole-rat in nociception is scanty and unique compared to that of other rodents. In the current study, the effect of DAMGO, DPDPE and U-50488 and U-69593 on ...
Respiratory stratagems, mechanisms, and morphology of the ‘lung’ of a tropical swamp worm, Alma emini Mich. (Oligochaeta: Glossoscolecidae): a transmission and scanning electron microscope study, with field and laboratory observations
(University of Nairobi,, 2006)
The swamp worm Alma emini subsists in the highly productive waterlogged swamps around the East African Lake Victoria. The soil consists of putrefying plant matter from which gases like methane, carbon dioxide, and hydrogen ...
Allometry of the limb bones of mammals from shrews (Sorex) to elephant (Loxodonta)
(University of Nairobi, 2009-08-20)
Measurements have been made of the principal leg bones of 37 species representing almost the full range of sizes of terrestrial mammals. The lengths of corresponding bones tend to be proportional to (body mass)0·35 and the ...
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 ...
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 ...
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 ...
Comparative gastrointestinal morphology of the Kori bustard and secretary bird
(University of Nairobi, 2005-05)
Two secretary birds and three Kori bustards were studied to determine differences between their body size and gastrointestinal morphology. Body measurements were made on captive, live birds and gastrointestinal measurements ...
The role of tendon elasticity in the locomotion of the camel (Camelus dromedarius)
(University of Nairobi, 2009-08-20)
Several ofthe distal leg muscles ofcamels have very short or even rudimentary muscle fibres. This makes it possible to calculate the elastic extensions of tendons that occur in running, from the leg positions observed in ...
