Genetic structure of Lake Magadi tilapia populations
(Wiley, 2000)
The control region of the mitochondrial DNA haplotype frequencies were significantly different among the two separate lagoon populations of Oreochromis alcalicus grahami in Lake Magadi and of O. a. alcalicus from lake ...
The morphology of the intestine of the insectivorous horseshoe bat {Rhinolophus hildebrandti, Peters): a scanning electron and light microscopic study
(Wiley, 1994)
The gastrointestinal tract of the horseshoe bat, Rhinolophus hildebrandti (Peters), was studied macroscopically, with the light microscope and with the scanning electron microscope. Macroscopically, the stomach was of the ...
A morphometric analysis of chloride cells in the gills of the teleosts Oreochromis alcalicus and Oreochromis niloticus and a description of presumptive urea-excreting
(1991)
The chloride cells of the teleost gills have structurally and functionally been an
extremely intriguing group of cells. Since they were first described by Keys & Willmer
(1932), the biology of these cells has attracted ...
A study of the morphology of the gills of an extreme alkalinity and hyperosmotic adapted teleost Oreochromis alcalicus grahami (Boulenger) with particular emphasis …
(Springer-Verlag, 1990)
The general gill morphology of Oreochromis alcalicus grahami, a teleost adapted to high salinity and hyperosmosis, is basically similar to that of other teleostean fish. The species has four pairs of gill arches, all of ...
Alteration in vomeronasal system anatomy in alcelaphine antelopes: Correlation with alteration in chemosensory investigation
(ScienceDirect, 1988)
Ruminants typically have an incisive papilla and incisive ducts located on the hard palate just behind the dental pad which are involved in transferring fluid-borne stimulus material from the oral cavity to the vomeronasal ...
Comparative in vitro study of interactions between particles and respiratory surface macrophages, erythrocytes, and epithelial cells of the chicken and the rat
(2008)
In mammals, surface macrophages (SMs) play a foremost role in protecting the respiratory system by engulfing and
destroying inhaled pathogens and harmful particulates. However, in birds, the direct defense role(s) that ...
What it takes to fly: the structural and functional respiratory refinements in birds and bats
(University of Nairobi, 2000-10)
In absolute terms, flight is a highly energetically expensive form of locomotion. However, with respect to its cost per unit distance covered, powered flight is a very efficient mode of transport. Birds and bats are the ...
Scanning electron microscope study of the spatial organization of the air and blood conducting components of the avian lung (Gallus gallus variant domesticus)
(University of Nairobi, 1988)
The lungs of the domestic fowl were prepared for scanning electron microscopy after vascular and airway latex rubber casting to demonstrate the spatial organization of the various structural components that are involved ...
Comparative respiratory morphology: Themes and principles in the design and construction of the gas exchangers
(University of Nairobi, 2000-02)
Along the evolutionary continuum, a kaleidoscope of gas exchangers has evolved from the simple cell membrane of the primeval unicells. The most momentous events in this process were: the intensification of molecular oxygen ...
Metabolism and antioxidant defense in the larval chironomid Tanytarsus minutipalpus: adjustments to diel variations in the extreme conditions of Lake Magadi.
(University of Nairobi, 2017)
Insect larvae are reported to be a major component of the simple but highly productive trophic web found in Lake Magadi (Kenya, Africa), which is considered to be one of the most extreme aquatic environments on Earth. ...
