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 ...
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 ...
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 ...
The digestive physiology of three East African herbivores: the elephant, rhinoceros and hippopotamus
(University of Nairobi, 2009-08-20)
Studies were conducted to compare structural and physiological differences in the digestive functions of three species of large ungulates; the elephant (Loxodonta africana), the Black rhinoceros (Diceros bicornis) and the ...
Stride lengths and stride frequencies of primates
(University of Nairobi, 2009-08)
Stride lengths and stride frequencies of primates have been observed or collected from the literature. Data for Galago, various monkeys and apes, and man have been collected. The quadrupedal primates take longer strides, ...
