The morphology of the respiratory organs of the African air-breathing catfish (Clarias mossambicus): A light, electron and scanning microscopic study, with morphometric observations
(1986)
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 ...
Water balance and osmotic regulation in the East African tenebrionid beetle Phrynocolus petrosus
(University of Nairobi, 1987)
1. When tenebrionid beetles of the species Phrynocolus petrosus undergo evaporative dehydration, the relative water content changes less than is predictable from the water loss alone. The discrepancy from the predictable ...
A fish in extreme alkalinity.
(1975-07)
Tilapia grahami (Boulenger), a small cichlid fish, inhabits extremely alkaline water where the total CO2 concentration exceeds 200 meq.L(-1), osmolality is about 600 mosm.L(-1), pH ranges between 9.6 and 10.5 and temperature ...
Importance of air and water breathing in relation to size of the African lungfish Protopterus amphibius Peters.
(1976)
1. Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake from air and water ranged from 60 ml O2 kg-1 h-1 STPD, in a 3-7 g ...
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 ...
