Behavioral changes in the grass shrimp , Palaemonetes pugio ( Holthuis ) , induced by the parasitic
Preliminary observations indicated that the grass shrimp, Palaemonetes pugio, parasitized by the isopod, Probopyrus pandalicola, captured significantly fewer prey items (Daphnia) and exhibited reduced activity compared to unparasitized conspecifics. Further research focused on elucidating the factors involved in altering the shrimp’s behavior. When viewed from above in an opaque container, acti...

متن کاملEffects of cyclic hypoxia on gene expression and reproduction in a grass shrimp, Palaemonetes pugio.
Cyclic changes in dissolved oxygen occur naturally in shallow estuarine systems, yet little is known about the adaptations and responses of estuarine organisms to cyclic hypoxia. Here we examine the responses of Palaemonetes pugio, a species of grass shrimp, to cyclic hypoxia (1.5-8 mg/l dissolved oxygen; 4.20-22.42 kPa) at both the molecular and organismal levels. We measured alterations in ge...
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...
