AB  - As the most widespread rodents in the temperate Palearctic, species from the genus   Apodemus can	(
provide  in1portant  clues  for  understanding  how  extant  flora  and  fauna \\:ere  established.	Here we	(
explore how to determine six Apodemus species precisely at the individual  level, evaluate    genetic
variation	in	local	populations,	geographic	regions  and	species	as	a	whole,  and	reconstruct	their	l
phylogeny.	Since the	genetic	variation	of	natural	populations from different	parts	of	a	species'
geographic range could result from persistence in different refuges during the last glacial period and the following re;olonization processes, our fmdings are discussed in that perspective. The Inter Simple Sequence Repeat- Polymerase Chain Reaction produced highly reproducible and polymorphic DNA
markers. Each of six optimized ISSR primers was sufficient for precise determination of six Apodemus	I
species and gained 98.3% polymorphic  bands on a total sample of 91 individuals  from 32   sample
localities from Europe and Asia. Phylogenetic trees were inferred from Nei's original .genetic distances and the parameters	of	intra- and	interpopulation and	regional	genetic variation	were calculated.
'
Distances between species ranged from 0.072, among closely related A. jlavicollis and A. sylvaticus, to
0.185 between A. mystacinus and A. agrarius. The tree topology was mainly in accordance with the existing phylogenetic relationships generally established for this genus, but, the range of interregional genetic distances within A. sylvaticus and A. ura/ensis reached the values obtained for closely related species.  According  to  our  results,  division  of  A. mystacinus and		A.  epimelas  into subgenus Karstomys,		is	not		sound,	although		karyological	differences		support	separation		from	the Sylvaemus	group.	Species		A.	uralensis,	A.	fl.avico/lis	and	A.	sylvaticus	display		a	strong population	substructure.	Based		on	the	high		divergence	between	southeastern	geographic regions, we can  hypothesize  that A.  sylvaticus survived  in  additional  northern  refugia, besides the traditionally accepted one. Moreover, high  genetic  distances  together  with,  high intrapopulation variability in A. jl.avicollis, indicate that there were probably many long-term isolated  glacial  shelters.  This  genetic  evidence,  together  with other  paleontological  data,  make it unlikely that physiographically complex and large Balkan Peninsula,  offered  a  single homogenous  refugium  throughout   the Pleistocene.

AB  - The faster evolving DNA characters are more informative for the estimation of phylogenetic relationships among very closely related species. Because of their exceptionally high mutation rate, microsatellites (SSR) may prove more useful than other DNA markers or sequence data. Evolutionary dynamics of the SSR loci may be evaluated by investigation of their structure, distribution and variability. The aim of our study was to investigate differences of their distribution in genomes of three species of the genus Apodemus (A.flavicollis, A. sylvaticus and A. agrarius). A total of 40 individuals from 7 localities were analysed by inter-simple sequence repeat (ISSR) technique, a SSR-primed PCR amplification, wich produces multilocus and highly polymorphous patterns. Each electrophoretic marker corresponds to a DNA sequence delimited by two inverted microsatellites. Out of twelve selected anchored and non-anchored primers with di- and trinucleotide repeats, six primers produced reproducible and polymorphic, species-specific paterns. These results indicate that ISSR markers are very useful tool for genetic characterization and phylogeny reconstruction for genus Apodemus species.

AB  - B chromosomes (Bs) are extra chromosomes to the standard complement that occur in many organisms. Because of high degree of homology with A chromosome, Bs of Apodemus flavicollis can not be accurately distinguished from chromosomes of normal complement at cytogenetic level, but there are differences at molecular level. AFLP is PCR-based technique that is useful for the rapid screening of genetic diversity. It generates hundreds of highly replicable markers, thus allowing high-resolution genotyping. We investigated usefulness of AFLP markers for genotyping mice in the context of Bs presence or absence. Total of 75 individuals were included in the study and 16 of them are B carriers, all captured on Mt. Fruška Gora. Out of 22, 14 primer combinations gave clear and reproducible pattern. Presence or absence of DNA fragments were transformed to binary data (1, 0). The computing of binary data was performed using MVSP software and genetic distances were estimated by Nei & Li's coefficient and UPGMA clustering. High level of detected intrapopulation polymorphism makes AFLP markers useful tool for genotyping analysis.

AB  - Supernumerary chromosomes, found in many species, are named B chromosomes (Bs) if they satisfy three criteria: dispensability, absence of paring with A chromosomes and non-Mendelian inheritance. Bs are frequently found in populations of yellow-necked mice, Apodemus flavicollis. Maintenance of Bs in populations is explained by two opposed models. Model signed parasitic claims that Bs are maintained by mechanism of accumulation despite detrimental effects on carrier fitness. On the other hand, heterotic model suggests that, in the absence of accumulation mechanism, small number of Bs could confer an adaptive advantage to carriers, while large number could be deleterious. With the aim of contributing to understanding the mechanisms of Bs maintenance in populations of A. flavicollis, differences in frequencies of Bs in age categories were analysed in 732 animals. Bs described as parasites reduce mean fitness of individuals carrying them. Therefore, it is expected that frequency of animals with Bs will decrease with age increase. Absence of significant statistical differences in frequency of Bs between six age categories point to the heterotic way of Bs maintenance in A. flavicollis.

AB  - The presence of B chromosomes (Bs) is frequently found in populations of yellow-necked mouse, Apodemus flavicollis. Differences in frequencies of Bs in age categories were analyzed in 717 animals in order to clarify the mechanisms of their maintenance in populations of A. flavicollis. The absence of statistically significant differences in the frequency of Bs between six age categories indicates that the maintenance of Bs in populations can be explained by in terms of their contribution to overall genetic diversity of the species rather than by parasitic behavior.
AB  - Prekobrojni hromozomi nazivaju se B hromozomi ako zadovoljavaju tri kriterijuma: nisu neophodni za preživljavanje, ne sparuju se sa hromozomima A seta i ne nasleđuju se mendelovski. B hromozomi su vrlo često prisutni u populacijama žutogrlog miša, Apodemus flavicollis. Njihovo održavanje u populacijama objašnjava se sa dva suprostavljena modela. Model označen kao parazitski tvrdi da se B hromozomi održavaju zahvaljujući mehanizmu akumulacije uprkos štetnim efektima na fitnes nosilaca. S druge strane, heterotički model sugeriše da u odsustvu akumulacije mali broj B hromozoma ima adaptivnu prednost za nosioce, dok veći broj može biti štetan. Ako B hromozomi, koji su označeni kao parazitski, redukuju fitnes kod jedinki koje su njihovi nosioci, onda je očekivano da frekvenca jedinki sa B hromozomima opada sa starošću. Analizirana je razlika u frekvenci B hromozoma u uzrasnim kategorijama kod 717 jedinki sa ciljem da se razjasne mehanizmi njihovog održavanja u populacijama A. flavicollis. Odsustvo statistički značajnih razlika u frekvenci B hromozoma između 6 uzrasnih kategorija ukazuje da se održavanje B hromozoma u populacijama ove vrste može objasniti njihovim doprinosom ukupnoj genetičkoj raznovrsnosti pre nego parazitskim ponašanjem.

B hromozomi su vrlo često prisutni u populacijama žutogrlog miša, Apodemus flavicollis. Njihovo održavanje u populacijama objašnjava se sa dva suprostavljena modela. Model označen kao parazitski tvrdi da se B hromozomi održavaju zahvaljujući mehanizmu akumulacije uprkos štetnim efektima na fitnes nosilaca. S druge strane, heterotički model sugeriše da u odsustvu akumulacije mali broj B hromozoma ima adaptivnu prednost za nosioce, dok veći broj može biti štetan. Ako B hromozomi, koji su označeni kao parazitski, redukuju fitnes kod jedinki koje su njihovi nosioci, onda je očekivano da frekvenca jedinki sa B hromozomima opada sa starošću. Analizirana je razlika u frekvenci B hromozoma u uzrasnim kategorijama kod 717 jedinki sa ciljem da se razjasne mehanizmi njihovog održavanja u populacijama A. flavicollis. Odsustvo statistički značajnih razlika u frekvenci B hromozoma između 6 uzrasnih kategorija ukazuje da se održavanje B hromozoma u populacijama ove vrste može objasniti njihovim doprinosom ukupnoj genetičkoj raznovrsnosti pre nego parazitskim ponašanjem.",
