As a basis for future conservation activities, the genetic and external
body morphology variability of the European mudminnow Umbra krameri, a
highly endangered fish species in Serbia and in Bosnia and Herzegovina,
was determined for existing populations with the use of molecular
markers (mitochondrial and microsatellite DNA) and geometric
morphometric methods. Mitochondrial DNA cytochrome b gene analysis
revealed two previously undescribed haplotypes: Da1 (the Lugomir
population from the Danube River basin) and Sa1 (the Bakreni Batar and
the Gromielj populations from the Sava River system), with a
corresponding genetic distance of 07\%. Paired values of F-ST and D-AS
distances for microsatellite marker data show that the difference
between the Danube and the Sava populations is seven to nine times
higher than the difference between the populations within the Sava River
system. Geometric morphometric analyses also support a clear separation
of the Lugomir population from the Bakreni Batar and the Gromielj
populations. The analysis of the body shape variation, however,
indicates a significant difference between the two genetically
indistinguishable Sava populations. The observed genetic and phenetic
relationships of the analysed mudminnow populations most probably
represent a consequence of historical, geographical and ecological
factors. These results will offer guidelines for future protection,
conservation and sustainable management of this species in the region.
