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 ...
Studies on renal excretion of potassium in the dik-dik antelope.
(Elsevier Science Ltd, 1988)
1. In a study on the renal handling of potassium by the dik-dik antelope, plasma and urine samples were analysed for potassium, sodium and creatinine concentrations and osmolality during dehydration and intra-ruminal loading ...
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 ...
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 ...
Renal excretion of urea and electrolytes in sheep and red deer.
(1969-11)
1. The effects of varying the intake of water and nitrogen on the renal excretion of urea and electrolytes has been studied in sheep and in red deer.2. The concentration of urea in the urine of both sheep and deer decreased ...
Salt excretion and saline drinking in the dik-dik antelope (Rhynchotragus kirkii)
(University of Nairobi,, 2013)
1.1. The ability of the dik-dik antelope to survive while drinking saline solutions was tested in controlled laboratory experiments by providing drinking water containing up to 0.5 M NaCl.2.2. Fluid intake increased from ...
The morphology of the respiratory organs of the African air‐breathing catfish (Clarias mossambicus): A light, electron and scanning microscopic study, with morphometric observations
(University of Nairobi, 2011-03)
The morphology of the gas exchange organs of the African air-breathing catfish (Clarias mossambicus) (Peters) have been examined grossly, and by light, electron and scanning microscopes. The respiratory organs in Clarias ...
Changes in thyroxine, triiodothyronine and metabolic rate in the dik-dik antelope (Rhynchotragus kirkii): effects of temperature and dehydration
(University of Nairobi, 1983-02)
Changes in plasma total thyroxine, triiodothyronine (T3) and metabolic rate were investigated in both hydrated and dehydrated dik-diks after prolonged exposure to ambient..
pH, Salinity and Temperature Tolerance of Lake Magadi Tilapia
(University of Nairobi, 1974-01)
THERE are several species of Tilapia isolated in the alkaline lakes of
the Great Rift Valley of Africa, living in extreme conditions of
temperature, salinity and pH. One of these fish, the Lake Magadi Tilapia
(Tilapia ...
