Within the scope of a research project on decapod crustaceans in Montenegrin aquatic ecosystems, a population of white-clawed crayfish of the Austropotamobius pallipes/italicus species complex has been recorded for the first time. Based on an analysis of morphometric and genetic parameters, it has been established that Austropotamobius italicus (Faxon, 1914) and its subspecies meridionalis are distributed in Dalmatia and in the central and southern parts of the Apennine Peninsula. The new finding represents: (1) extension of the known range of the species complex A. pallipes/italicus on the Balkan Peninsula, and (2) determining the limits of the distribution and of this isolated population of that complex. The ascertained characteristics of the white-clawed crayfish's newly discovered population in Montenegro are significant from the viewpoint of global conservation of the species in question. © Koninklijke Brill NV, Leiden, The Netherlands 2012.

A conservation strategy for crayfish from the Astacidae family was developed for the populations inhabiting the aquatic ecosystems of the Central Balkans (territories of Serbia and Montenegro). The strategy, based upon the ESHIPPO crayfish model, uses the Ecological Specialization of taxa, the factors endangering the biodiversity (HIPPO: Habitat alteration, Invasive species, Pollution, Population growth, Overexploitation) and the Index of the Local Adaptive Population of Crayfish (ILAP) (genetic, morphological and structural characteristics of the local population). The crayfish populations with the highest values in model have the highest conservation priority and represent primary Elemental Conservation Units (ECUp). The results indicate that genetic factors play an important role in the final assessment of the value of conservation priorities in 25% of cases. The results obtained by the model indicate that in the area of the Central Balkans, the populations of Astacus astacus and Austropotamobius italicus meridionalis have a greater risk of extinction and a higher conservation priority than Austropotamobius torrentium. The new structure of the model enables a more precise estimation of the local extinction risk, and it provides the choice of the most rational conservation measures, therefore, having both ecological and economic importance on national and/or regional level. © 2015, Springer International Publishing Switzerland.

Research of the population of crayfish of the family Astacidae on the territory of Montenegro and Serbia by using COI gene mDNA as a genetic marker, have shown that all populations of the species Austropotamobius torrentium are homogenous and belonging to the haplogroup "Southern Balkan". Population of Austropotamobius italicus, recorded only in Montenegro in river Zeta's upper flow, belongs to the (haplogroup), subspecies meridionalis. The findings of Austropotamobius italicus meridionalis are new and an expansion of the southern range border of this subspecies in the Balkan peninsula. For the populations of Astacus astacus, two haplogroups have been detected; the one from Serbia belongs to a new haplotype and is considered to be evolutionally older than the ones from Montenegro and Croatia. Using COI gene analysis, the highest value of nucleotide diversity (π) was noted for the species Austropotamobius torrentium, π = 4.6% (0.046±0.006); the lowest one was for the species Astacus astacus, π = 3.2% (0.032±0.006). The achieved results implicate urgent measures for conservation of populations Astacus astacus on the territory of Serbia and Austropotamobius italicus meridionalis on the territory of Montenegro, accompanied by the use of stricter measures in the management of populations of Astacus astacus in Montenegro.
