متن کاملAssessment of the pressure-volume relationship of the single ventricle of the grass shrimp, Palaemonetes pugio.
The ventricular pressure-volume (PV) relationship has been used extensively to study the mechanics and energetics in multi-chambered hearts of closed circulatory system vertebrates. In the current study we applied the use of PV loops in the assessment of cardiac mechanics and energetics in the single ventricle of a decapod crustacean possessing an open circulatory system. Anatomical differences...
متن کاملThe effects of salinity and temperature on the transparency of the grass shrimp Palaemonetes pugio.
Transparency is an effective form of camouflage, but it must be present throughout the entire volume of an animal to succeed. Certain environmental stressors may cause physiological responses that increase internal light scattering, making tissue less transparent and more conspicuous to predators. We tested this in the transparent grass shrimp, Palaemonetes pugio, which is found in shallow estu...
متن کاملEffects of Solid Coal Combustion Residue on the Estuarine Grass Shrimp (palaemonetes Pugio)
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...
متن کاملThe role of native salinity regime on grass shrimp (Palaemonetes pugio) sensitivity to cadmium.
In euryhaline crustaceans, sensitivity to toxic trace metals may be linked to osmoregulation and salinity conditions. This study investigated if grass shrimp (Palaemonetes pugio) populations from different salinity regimes differed in sensitivity to cadmium (Cd). Grass shrimp were collected in May 2011 from two marsh sites with average salinities of ~3.0 ppt and 24.0 ppt. Groups were acclimated...
