Resistance to the crayfish plague, Aphanomyces astaci (Oomycota) in the endangered freshwater crayfish species, Austropotamobius pallipes
The pathogen Aphanomyces astaci Schikora 1906 is responsible for the decline of the native crayfish species of Europe, and their current endangered status. This pathogenic species is native to North America and only colonizes aquatic decapods. The North American crayfish species have a high resistance to this pathogen, while species from other regions are highly susceptible. However, recent fie...
متن کاملThe British freshwater crayfish Austropotamobius pallipes
lives in streams or pools that are liable to dry up or become stagnant, and these animals are known to leave water voluntarily to forage or to invade neighbouring habitats (Huxley, 1896; Taylor and Wheatly, 1980). When placed in air, the gills collapse and the crayfish suffer continuously from systemic hypoxia and hypercapnia. Associated with an initial virtual anoxia and a switch to anaerobic ...
متن کاملInvestigation of ornamental crayfish reveals new carrier species of the crayfish plague pathogen (Aphanomyces astaci)
Several North American crayfish species have so far been identified as carriers of the crayfish plague agent Aphanomyces astaci. The pathogen is responsible for the declines of thousands of European crayfish populations. Currently, one of the introduction pathways of North American crayfish species is the aquarium trade which may sometimes be followed by intentional release or unintentional esc...
متن کاملPrevalence of the Crayfish Plague Pathogen Aphanomyces astaci in Populations of the Signal Crayfish Pacifastacus leniusculus in France: Evaluating the Threat to Native Crayfish
Aphanomyces astaci, the crayfish plague pathogen, first appeared in Europe in the mid-19(th) century and is still responsible for mass mortalities of native European crayfish. The spread of this parasite across the continent is especially facilitated by invasive North American crayfish species that serve as its reservoir. In France, multiple cases of native crayfish mortalities have been sugges...
متن کاملCalcium balance at the postmoult stage of the freshwater crayfish Austropotamobius pallipes (Lereboullet).
Net uptake of calcium by Austropotamobius begins 15-30 min after the moult and rapidly reaches a maximum level (2 /imoles/g/h at io°C) which is maintained throughout stages A and B. At stage Cx the rate of net uptake falls sharply to a lower level which is gradually reduced until equilibrium is reached at C4. The uptake mechanism is near-saturated at 0-4 mM-Ca/1 and half-saturated at 0-13 mM-Ca...
