...Patricia A. Wright; Chris M. Wood; Jonathan M. Wilson Increased renal ammonia excretion in response to metabolic acidosis is thought to be a conserved response in vertebrates. We tested the hypothesis that Rhesus (Rh) glycoproteins in the kidney of the freshwater common carp, Cyprinus carpio , play...

Huising SUMMARY We established that corticotropin-releasing hormone (CRH), CRH-binding protein (CRH-BP) and CRH-receptor 1 (CRH-R1) are expressed in the gills and skin of common carp Cyprinus carpio , an early vertebrate. Immunoreactive CRH...

MYH DNA clones were also...

... specialists, we chose the common carp ( Cyprinus carpio , Cyprinidae) and for the hearing generalists the European perch ( Perca fluviatilis , Percidae). Data show that the carp's hearing is only moderately masked by the quiet habitat noise level of standing waters (mean threshold shift 9 dB) but is heavily...

...Juriaan R. Metz; Erwin H. van den Burg; Sjoerd E. Wendelaar Bonga; Gert Flik SUMMARY Isogenic carp Cyprinus carpio L. were acclimated to water temperatures of 15, 22 and 29°C for at least 8 weeks. The acclimations consistently resulted in slightly, but significantly, different plasma osmolality...

... Cyprinus carpio use crossflow filtration and/or palatal protrusions during benthic feeding. We found that carp use crossflow filtration to concentrate small food particles in the pharyngeal cavity while expelling small dense inorganic particles through the opercular slits and via spits. Our results suggest...
