Gangliogenesis in the prosobranch gastropod Ilyanassa obsoleta.
We determined that the larval nervous system of Ilyanassa obsoleta contains paired cerebral, pleural, pedal, buccal and intestinal ganglia and unpaired apical, osphradial, and visceral ganglia. We used a modified form of NADPH diaphorase histochemistry to compare the neuroanatomy of precompetent (including specimens 6, 8, and 12 days after hatching), competent, and metamorphosing larvae with po...
متن کاملActivity concentrations of natural radionuclide levels in well waters of Ago Iwoye, Nigeria
Background: Natural Radioactivity, though natural requires concentration monitoring, especially for the health/ environmental checks of the populace. Materials and Methods: The activity concentrations of 40K, 238U and 232Th in the waters from wells with depths ranging between 141.0 - 214.0 feet were randomly sampled and determined from 20 locations in Ago-Iwoye town in South Western, ...
متن کاملEstimation of Bed Load Transport in River Omi, South Western Nigeria using Grain Size Distribution Data
Representative bed material samples were taken from the two gauging sites on rivers omi for sieve analysis to obtain the grain size distribution of its bed materials. The analyses of the grain size distribution showed that the bed load accounted for 9% of the total estimated suspended sediment load of 1,703, 548.113 kg/annum in river omi. River omi bed material had a geometric mean particle siz...
متن کاملComparison of Sediment Transport Models on River Omi, South-Western Nigeria
The processes of sediment transport, scour, and deposition in an alluvial channel are extremely complex. Theoretical developments of sediment transport functions for different flow and sediment conditions are based on assumptions of different degrees of complexity [1]. Some of the simplified assumptions are based on idealized laboratory conditions that may not be true for the much more complica...
متن کاملSpatial vision in the prosobranch gastropod ampularia sp
The eyes of gastropods of the genus Ampularia superficially resemble the well-developed camera-type eyes of Littorina littorea and Strombus raninus. The eyes are of the closed-vesicle type, having a cornea and a lens that is separated from the retina by a narrow vitreous body. Light and electron microscopy were used to generate an accurate geometrical model of the Ampularia sp. eye, which was t...
