Title of Document: INDIVIDUAL AND POPULATION-LEVEL EFFECTS OF SOLID COAL COMBUSTION RESIDUE ON THE ESTUARINE GRASS SHRIMP (PALAEMONETES PUGIO) Danika M. Kuzmick, Master of Science, 2006 Directed By: Dr. Christopher Rowe, Department of Marine Estuarine and Environmental Science Burning coal for electricity produces solid coal combustion residue (CCR), which is rich in potentially toxic trace ele...

We developed short tandem repeat markers for Palaemon septemtrionalis and tested their utility analysing population genetics. Six were selected genotyping ability suitability genetic analyses, the differences between two populations from different rivers evaluated using these markers. The pairwise fixation index value was 0.01756 (P=0.036), weak but statistically significant, suggesting a low l...

The mechanism of sound reception and the hearing abilities of the prawn (Palaemon serratus) have been studied using a combination of anatomical, electron microscopic and electrophysiological approaches, revealing that P. serratus is responsive to sounds ranging in frequency from 100 to 3000 Hz. It is the first time that the Auditory Brainstem Response (ABR) recording technique has been used on ...

IT has been suggested (Huxley, 1927; Shaw, 1928) that in various animals, such as some Crustacea which show disharmonic growth, there exist growth centres correlated with the active growth of specific organs or regions. Also that the growth of neighbouring parts is correlated with the growth of the heterogonic organ. In Maia squinado (Huxley, 1927) and Inachus dorsettensis (Shaw, 1928) the grow...

Accumulation of cadmium in the hepatopancreas of the common prawn Palaemon serratus (Pennant) and ultrastructural changes m hepatopancreatic cells were examined after exposure to 3 cadmium concentrations (5, 25.50 ppm) for 44 h. Accumulation of cadmium Ions in 50 ppm solution was 800 % higher compared with control specimens. Absorptive and fibrillar cells (Rand F-cells) in the hepatopancreas we...
