The morphology of the gills of the freshwater African crab Potamon niloticus (Crustacea: Brachyura: Potamonidae): A scanning and transmission electron microscopic study
(Wiley, 1990)
The gills of the African freshwater crab Potamon niloticus-Ortmann have been investigated by scanning and transmission electron microscopy. Potamon has seven pairs of phyllobranchiate gills contained in the branchial ...
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 ...
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 ...
A morphological and morphometric study of the prosimian lung: the lesser bushbaby Galago senegalensis.
