An ultrastructural and histochemical study of the axial musculature in the African lungfish.
Red, intermediate, and white axial muscle fibres of African lungfish were studied using histochemical techniques and electron microscopy. Gross dissection revealed the presence of a small wedge of red coloured muscle along ...
Colonic absorption and secretion of electrolytes as seen in five species of East African herbivorous mammals
(University of Nairobi, 1980)
1. The camel, sheep, goat and donkey were equally efficient in recovering fluids from colonic contents. Zebu cattle were the least efficient. 2. Compared to other species, Zebu cattle demonstrated a reduced sodium and ...
Cyclic changes in the osmolality and electrolyte composition in the gastrointestinal tract of the rock hyrax.
The rock hyrax has been shown to have a very unusual and complex digestive tract. The gastrointestinal tract is comparable to that of the simple and complex stomach of mammals as well as to that of birds. Determinations ...
Gastrointestinal osmolality electrolyte and organic acid composition in five species of East African herbivorous mammals.
Inherent differences observed in ionic composition of gastrointestinal contents due to diet, feeding regimen and (or) site along the length of the digestive tract were controlled so that a clearer understanding of ...
Effects of dehydration and heat stress on food intake and dry matter digestibility in East African ruminants
Comparative investigations were made between wild and domestic ruminants from arid and semi-arid regions and those species from non-arid areas in an attempt to evaluate the adaptations of these ruminants in terms of the ...
Moving cheaply: energetics of walking in the african elephant
Large animals have a much better fuel economy than small ones, both when they rest and when they run. At rest, each gram of tissue of the largest land animal, the African elephant, consumes metabolic energy at 1/20 the ...
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..

Na+ AND Cl~ EFFLUXES AND IONIC REGULATION IN TILAPIA GRAHAMI, A FISH LIVING IN CONDITIONS OF EXTREME ALKALINITY
The osmoregularity ability of the cichlid Tilapia grahami enables this fish to live in conditions of extreme alkalinity (Reite, Maloiy & Aashaug, 1974; Maloiy et al. 1978). In this paper we describe the ionic balance of ...
