Dispersal of Freshwater Bivalves

Potassium and Rubidium Uptake in Freshwater Bivalves

Potassium transport characteristics were investigated in three species of freshwater bivalves: a corbiculid, Corbiculafluminea, and two unionids, Carunculina texasensis and Ligumia subrostrata. Using K, all three were found to take up potassium from dilute artificial pondwater ([K] about O.OSmmolP). The influx (7i) was 0.72/iequivg"drytissueh^ in the corbiculid, significantly higher than the va...

Scale-dependence and Mechanisms of Dispersal in Freshwater Zooplankton

Communities of organisms form as a result of both interspecific and abiotic interactions within local habitat patches and dispersal among patches in a region. Local processes are expected to play a dominant role when dispersal occurs much more often than extinction. We 5 performed two field experiments to examine rates and mechanisms of dispersal in freshwater pond zooplankton communities. Firs...

Application of RAPD-PCR in Taxonomy of Certain Freshwater Bivalves of Genus Caelatura

Adult specimens of the two common freshwater bivalves, Caelatura (Caelatura) companyoi and Caelatura (Caelatura) prasidens belonging to family Unionidae were collected from the River Nile at Giza governorate in Egypt. These two species were described by some authors as one species and others separated them as two different species. In the present study, random amplified polymorphic DNA-polymera...
