The effects of temperature on oxygen consumption of eggs and hatchlings of the nile crocodile (Crocodylus niloticus)
(1989)
1. The oxygen uptake (View the MathML source) of eggs and hatchlings of the Nile crocodile was measured at ambient temperatures (Ta) of 25, 32 and 37°C.
2.
2. At a Ta of 32°C, View the MathML source was found to be stable ...
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 ...
Renal excretion of urea in a small east African antelope, the dik-dik (Rhynchotragus kirkii)
(1988)
1. A study on the renal handling of urea by the dik-dik antelope (Rhynchotragus kirkii) was conducted. 2. Plasma and urine samples were analysed for osmolality, urea and creatinine concentrations during dehydration and ...
Urea excretion as a strategy for survival in a fish living in a very alkaline environment.
(Nature Publishing Group, 1989-01)
Ammonia is toxic to all vertebrates. It can be converted to the less toxic urea, but this is a metabolically expensive process found only in terrestrial vertebrates that cannot readily excrete ammonia and marine fish that ...
Energetic cost of carrying loads: have African women discovered an economic way?
(Nature Publishing Group, 1986-02)
When travelling in East Africa one is often surprised at the prodigious loads carried by the women of the area. It is not uncommon to see women of the Luo tribe carrying loads equivalent to 70% of their body mass balanced ...
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. IX. Functional and structural limits for oxygen flow.
(1981-04)
This paper presents the synthesis and interpretation of a series of correlated studies of the mammalian respiratory system--measurements of maximal rate of O2 consumption, the lung's diffusing capacity, the mitochondrial ...
