Taxonomic position of the Balkan spined loach, Sabanejewia balcanica (Karaman, 1922) is still uncertain. There are pronounced differences in morphological characters among individuals from different populations, which led to description of various populations as species, subspecies and clinal variation. In this investigation we aimed to describe morphological and genetic diversity of S. balcanica in Bosnia and Herzegovina, investigate phylogenetic relationships among populations and get insight into their evolutionary history. The obtained results revealed pronounced genetic structuring inside S. balcanica in Bosnia and Herzegovina and moderate to high genetic diversity contained inside each population. Lineages and sublineages of S. balcanica in Bosnia and Herzegovina diverged during Pleistocene epoch and their evolution was most likely shaped by alteration of glaciations with interglacial periods. Based on morphometric characters, investigated populations fall within already reported range for S. balcanica. However, distinctiveness of populations from Brka, Suturlija and Turija Rivers from the remaining populations in their body shapes have been observed and discussed in relation to separate evolutionary history of some populations.

波斯尼亚和黑塞哥维那的Sabanejewia balcanica(Cobitidae,Actinopterygii)的形态和遗传多样性

巴尔干脊泥achSabanejewia balcanica(Karaman,1922)的生物分类位置仍然不确定。来自不同种群的个体之间的形态特征存在明显差异,这导致将各种种群描述为物种,亚种和生殖器变异。在这项调查中,我们旨在描述波斯尼亚和黑塞哥维那巴尔卡尼卡链霉菌的形态和遗传多样性,调查种群之间的系统发生关系并深入了解其进化史。获得的结果表明,波斯尼亚和黑塞哥维那的巴尔卡尼卡链霉菌内部具有明显的遗传结构,每个种群内部均具有中等至高度的遗传多样性。谱系和的亚型是S. balcanica在更新世时期,波斯尼亚和黑塞哥维那的冰川分叉,它们的演化很可能是由于冰川期与冰川间期的变化而形成的。根据形态特征,调查的种群落在S. balcanica的已报道范围内。然而,已经观察到并讨论了Brka河,Suturlija河和Turija河的种群与其余种群的体型之间的区别,并与某些种群的单独进化史相关联。
