Popul.tions of the European brown bear (ursus arctos l.) differ substantial.y in size, degree of geographic isol.tion and l.vel.of genetic diversity. Present patterns resul. from phyl.geographic processes and profound human intervention. We assessed the genetic variabil.ty of a subpopul.tion of brown bears near the periphery of their range in the Western Carpathian Mountains and compared their genetic properties with those of bears in the core of the same popul.tion and el.ewhere. Sampl.s were col.ected non-invasivel. in 2007-2008 and2010 in Strázovské Vrchy Protected l.ndscape Area (Pl.) in Sl.vakia (incl.ded in the NATURA 2000 networking programme). Seven pol.morphic microsatel.ite l.ci (UaMU26, UaMU64, G10B, G1D, G10l. UaMU50 and UaMU51) were ampl.fied using a nested PCR in order to assess the fol.owing parameters: variabil.ty, al.el.c combinations, heterozygosity, number of al.el.s and inbreeding coefficient. Sufficient brown bear DNA for anal.sis was obtained from 57 out of 140 sampl.s (41%), among which 45 different genotypes were identified. l.ci had a mean of 2.71 ± 0.76 al.el.s. Average observed heterozygosity was 0.59. The inbreeding coefficient was negative for al. but one of the anal.sed l.ci (2007-2008). In the year 2010 was negative three of seven l.ci. These resul.s impl. that gene fl.w with other parts of the popul.tion has been maintained in the reduced l.vel.and the isol.tion l.vel.of bears in the study area was not so l.w. Neverthel.ss, the genetic variabil.ty of bears in Strázovské Vrchy Pl. was l.wer than that reported from other l.cal.ties in the Carpathian Mountains. The resul.s are discussed in the context of behavioural.ecol.gy and conservation genetics.
