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 ...

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 ...

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 ...

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 ...

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 ...

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 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 plasma total thyroxine, triiodothyronine (T3) and metabolic rate were investigated in both hydrated and dehydrated dik-diks after prolonged exposure to ambient..

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 ...
