Developmental physiology of the red swamp crayfish Procambarus clarkii
… the development of the red swamp crayfish Procambarus clarkii. Investigations focused on cardiac development and the ontogeny of the regulatory mechanisms of the cardiovascular system. Investigations concentrated on two areas: (1) the development of a staging scheme for P. clarkii, and (2) …

Thermoregulatory behavior of the crayfish Procambarus clarkii in a burrow environment
… thermoregulation of the red swamp crayfish, Procambarus clarkii, was investigated and the environmental parameters of crayfish burrows were measured in situ. Although temperatures within burrows fluctuated less than surface temperatures in the Mojave Desert, crayfish can experience …

Enhancement and monitoring of the Procambarus clarkii population in Lake Mead
Procambarus clarkii are found in extremely low numbers throughout Lake Mead, AZ-NV. The crayfish are an important dietary component for game fish. Enhancement of the crayfish population would broaden the fishery forage base. Crayfish were stocked and monitored in a study cove on Saddle Island to …

Estudios biológicos sobre procambarus clarkii girard (decapoda cambaridae) en las marismas del bajo Guadalquivir
Procambarus clarkii Girard, es un cangrejo de agua dulce, vulgarmente conocido como cangrejo americano o rojo, originario de Estados Unidos (zona Sur central) y México (zona Noreste) (HOBBS, 1972 a). Fue introducido en Las Marismas del Bajo Guadalquivir en 1974 y debido a que presenta una alta tasa …

Mannose and Lipopolysaccharide Receptors on the Surface of Granular Hemocytes from the Crayfish <em>Procambarus clarkii</em>.
<p><em>Procambarus clarkii</em> hemocytes have been shown to bind to both LPS and a mannose containing neoglycoprotein conjugated to fluorescent probes. A decrease in the observed number of fluorescent hemocytes indirectly indicated that the binding of FITC-LPS to these cells is impaired by initial …

Crayfish as a biomonitor for the algal toxin microcystin-LR
… In the microcystin detection experiment, Procambarus clarkii moved away from microcystin-LR (p < 0.001) while Orconectes rusticus did not respond (p = 0.28). Neither species could be reliably trained to move to the tank’s center when microcystin-LR was present. To understand why, I tested …

Host Defense Mechanisms in the Crayfish: the Effect of Injection with Live or Killed Bacteria.
<p>An increase in attachment of SRBCs to <em>Procambarus clarkii</em> hemocytes has been shown after the crayfish were injected with a live or killed <em>Pseudomonas</em> strain RS2b. The increase in attachment occurred at 8 hours post injection and peaked at 24 hours for both experimental groups. …

Sensitivity to chemical stimuli plays a fundamental role in the food preferences. Examples in the evolutionary scale: 1. Role of the walking leg chemoreceptors in the red swamp crayfish Procambarus Clarkii 2. PROP bitter taste sensitivity and its nutritional implications in Humans
… the evolutionary scale. The red swamp crayfish Procambarus clarkii (Girard, 1852) (Crustacea: Decapoda) is an invasive species of freshwater habitats that has spread worldwide. In crayfish, like in other decapod crustaceans, reception of chemical cues occurs by way of peripheral chemoreceptors …

Effects of reflection and social isolation on crayfish behaviour /
… the activity of solitary adult crayfish (Procambarus clarkii) in a glass aquarium containing fresh water and no objects. Five distinct behaviours were observed: rearing up (climbing on the wall), turning around, cornering (facing the comer), backward walking, and crossing (crossing the …

Responses to Reflection in Two Invertebrate Species
… the responses to reflection in both the crayfish Procambarus clarkii and the fruit fly Drosophila melanogaster. Responses to reflection in crayfish depend on social status and the current work suggests that learning and memory consolidation are required for these responses to be altered. Crayfish …

Impacts of introduced crayfish on Ash Meadows aquatic communities: Ash Meadows National Wildlife Refuge, Nevada
… species, most notably the Red Swamp Crayfish (Procambarus clarkii). The interactions are of concern to the Refuge because of the presence of the federally protected endemic life, specifically pupfish (Cyprinodon nevadensis mionectes and Cyprinodon nevadensis pectoralis) and the federally …

Applying new aquatic habitat data to manage invasive and imperiled crayfishes in North America
… range extent of the emerging invasive crayfish Procambarus clarkii in the Laurentian Great Lakes. I created an SDM of all suitable crayfish habitat across the Great Lakes, then constrained this habitat to areas anticipated to be suitable for P. clarkii based on known physiological limitations of …

IMPROVING THE ASSESSMENT OF SPREAD AND IMPACTS OF FRESHWATER INVASIVE SPECIES
… distribution and spread of an invasive crayfish, Procambarus clarkii, in Italy using data coming from multiple data sources: published literature, grey literature, experts’ communications, and online forums. Eradication of FIS is often feasible only when the focal species has yet to establish a …

The behavioural function of pheromones in crayfish
Pacifastacus leniusculus and Procambarus clarkii are highly invasive freshwater crayfish and are having detrimental impacts on native species and habitats throughout Europe. The application of pheromone baits have been proposed as a way of increasing trap efficiency for population control, however …

Ecosystem impacts of the invasive rusty crayfish (Faxonius rusticus) over time
… gastropods (snails). The red swamp crayfish (Procambarus clarkii) is another invasive crayfish that has caused declines of macrophytes, leading to decreases in water clarity in shallow lakes and wetlands in Asia and Europe. In my first study, I used remote-sensed estimates of Secchi disc depth …

INVASION DYNAMICS OF FRESHWATER CRAYFISH IN A MAN-DOMINATED LAND: SPATIO-TEMPORAL, ECOLOGICAL AND HUMAN DIMENSIONS
