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 ...
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 ...
Thermoregulation and heat balance in the dik-dik antelope (Rhynchotragus kirki): a field and laboratory study.
(Elsevier Science Ltd, 1985)
xperiments were conducted in the field to study the physiological responses of dik-dik antelope to direct solar radiation and shade. The results were compared to those obtained in the laboratory. The rates of metabolic ...
Design of the mammalian respiratory system. III Scaling maximum aerobic capacity to body mass: wild and domestic mammals.
(1981-04)
The purpose of this study was to determine whether the maximal rate of oxygen consumption (Vo2max) is scaled proportionally to Mb1.0, as the diffusing capacity of the lung, or proportionally to Mb0.75, as the standardized ...
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 ...
Function of the lower intestine and osmoregulation in the ostrich: preliminary anatomical and physiological observations.
(1984-10)
The gross anatomy of the lower intestine of the African ostrich (Struthio camelus) was investigated in four adult birds shot in the wild. The presence of 80 cm long paired caeca, and approximately 10 m of colon between ...
