Resistance to dehydration and positive hygrotaxis in the invasive red swamp crayfish Procambarus clarkii

Red Swamp Crayfish (procambarus Clarkii) in River Nile, Egypt

Origins of the invasive red swamp crayfish (Procambarus clarkii) in the Santa Monica Mountains

Although native to the southeastern United States, the red swamp crayfish (Procambarus clarkii) has become established worldwide through accidental and intentional actions by humans. In the Santa Monica Mountains of southern California, the presence of the omnivorous crayfish is associated with the absence or reduced abundance of native amphibians. The original source of P. clarkii in southern ...

In-Depth Transcriptome Analysis of the Red Swamp Crayfish Procambarus clarkii

The red swamp crayfish Procambarus clarkii is a highly adaptable, tolerant, and fecund freshwater crayfish that inhabits a wide range of aquatic environments. It is an important crustacean model organism that is used in many research fields, including animal behavior, environmental stress and toxicity, and studies of viral infection. Despite its widespread use, knowledge of the crayfish genome ...

Acute toxicity of lead nitrate to red swamp crayfish, Procambarus clarkii

Red crayfish, Procambarus clarkii, is widely farmed in the southern states of Louisiana and Texas. It is the most valuable of commercial crayfish species in the United States, where it is considered a delicacy. In recent years, its availability has decreased due to environmental contamination by toxic chemicals including lead. In the present study, we conducted a ninety-six-hour static renewal ...

Polarization sensitivity in the red swamp crayfish Procambarus clarkii enhances the detection of moving transparent objects.

We tested the hypothesis that polarization sensitivity enhances the detection of moving, transparent objects by examining the escape response of the red swamp crayfish (Procambarus clarkii Girard) from a visual threat. A transparent, birefringent target trans-illuminated by either partially linear polarized or unpolarized light was advanced toward individual crayfish. The optical axis of the ta...
