Application of microsatellite analysis on Astacus astacus and Astacus leptodactylus populations from Croatia - preliminary results
Recently, microsatellite markers have been successfully applied to reveal genetic patterns in populations of crayfish species. In this research, we used four microsatellites primarily aiming to check their possible usefulness in detecting hybrids between noble and narrow-clawed crayfish. These hybrids have been previously obtained under laboratory conditions, and their occurrence in natural habitats has been mentioned in the literature. Existence of possible hybrids between noble and narrow-clawed crayfish in natural habitats was approached by morphometric analyses. Results on morphometry were ambiguous, and the existence of hybrids has not been approved with certainty. Application of microsatellites in this research was done on the samples from pure A. leptodactylus and A. astacus populations, from the mixed population, and on the samples of hybrids obtained from an experimental trial. Obtained results are complex, and their comprehensive interpretation would require inclusion of more individuals. Nevertheless, it was proved that microsatellites developed for A. astacus, and novel microsatellite marker isolated from A. leptodactylus, gave successful amplification for both species. Analysis of samples from the Mrežnica River (downstream A. leptodactylus population ; upstream A. astacus population), gave insight into the population structure for both species. A. astacus shows lower degree of heterozygosity, what could be a consequence of a crayfish plague outbreak.
