Adaptations of a tropical swamp worm, alma emini, for subsistence in a H2S-rich habitat: evolution of endosymbiotic bacteria, sulfide metabolizing bodies, and novel processes of elimination of neutralized sulfide complexes
(1998)
The epithelial cell lining of the respiratory groove of Alma emini, an oligochaete glossoscolecid worm that lives in a hydrogen sulfide (H2S)-rich tropical swamp, was investigated by transmission electron microscopy to ...
Histological Reactions to Bites of Amblyomma variagatum and Rhipicephalus appendiculatus (Acari: Ixodidae) Fed Simultaneously on Naive or Sensitized Rabbits
(Entomological Society of America, 1990)
Histopathological studies on attachment sites of nymphs, 48 h after attachment on three groups of rabbits, have revealed differences that were related to the rabbits'previous tick experience. Feeding lesions caused by ...
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 ...
The morphology of the lung of a tropical terrestrial slug Trichotoxon copleyi (Mollusca: Gastropoda: Pulmonata): A scanning and transmission electron microscopic study
(1989)
The lung of the slug Trichotoxon copleyi is located in the body mantle where it opens to the outside through an adjustable pneumostome situated on the right side. The respiratory surface of the lung is profusely vascularized ...
A stereological comparison of villous and microvillous surfaces in small intestines of frugivorous and entomophagous bats: species, inter-individual and craniocaudal differences
(1997)
The extents of functional surfaces (villi, microvilli) have
been estimated at different longitudinal sites, and in the
entire small intestine, for three species of bats belonging to
two feeding groups: insect- and ...
Morphometries of the avian lung: The structural-functional correlations in the design of the lungs of birds
(ScienceDirect, 1993)
1. Birds present remarkably variable pulmonary morphometric characteristics which closely correspond with factors such as phylogeny, body size, mode of life and habitat. These factors determine the oxygen demands, energetics ...
The morphology and morphometry of the adult normal baboon lung (Papio anubis).
(1987)
Numerous morphological studies on diverse aspects of the organisation of the
mammalian lung notably in respect to structure, development, response to irritants
and functional demands are currently available. Some of the ...
Scanning and transmission electron microscopic study of the tracheal air sac system in a grasshopper Chrotogonus senegalensis (Kraus)—Orthoptera: Acrididae: Pyrogomorphinae
(Wiley, 1989)
The morphology of the trachea-air sac system in a species of grasshopper Chrotogonus senegalensis has been studied by using scanning and transmission electron microscopes. Capacious air sacs were formed as dilatations along ...
