THE STONE CRAYFISH (AUSTROPOTAMOBIUS TORRENTIUM), PRESENT STATUS IN ROMANIA, DISTRIBUTION, PHILOGENY AND POPULATION EVALUATION

Project no. 1019/2009

The goal of this project is to establish the geographical areal of the species, to investigate the quality of the ecosystems in which the species lives and to characterise the species populations from the morphological and genetic point of view.

Project justification:

In the natural dynamics of ecosystems, numerous species have extended or diminished their areal, new species have been artificially introduced that have replaced the native species and sometimes the habitat have been destroyed, factors that limit the current knowledge on astacids from Romania and Europe.

As far as the stone crayfish (Austropotamobius torrentium, Schrank, 1803), Subphyillum: Crustacea, Family: Astacidae, is concern, the knowledge is even more limited, the international status of the species being insufficient known (IUCN, Groombridge, 1994). Because, the European areal of the species has his estic limit in Romania and from the ecological point of view is divided by Mures River (the natural barier for this species characteristic to the mountain springs), we consider that our data will complete the European knowledge on this species.

The Habitats Directive, through Anexx V, considers the stone crayfish in the prioritary species category for protected areas management, one more reason for knowing its actual geographical spreading. For a sustainable management it is compulsory to know the biological and ecolological parameters that maintain the species in optimum conditions. To this effect we propose complex investigations regarding the populations dimensions and biological state cummulated with habitats structure, chemo-physical characteristics and also the quality of the water interpreted from the indicator species analysis. Our studies will establish the complete species distribution for Romania, the optimal ecological parameters, the morphological characteristics of populations, with the investigation of their genofond, outlining the evolutive line of which the populations came and identifying the possible speciation. We will take also into account other disturbance factors in the species equilibrium like the invasive species and the anthropic impact.
