title: Ulnaria williamsii sp. nov. (Bacillariophyta, Ulnariaceae) from Mongolia and Its Reproductive Features Relevant for Species Dispersal and Evolution
abstract: An unknown species of the diatom genus Ulnaria was identified during the study of freshwater environments in Mongolia. Monoclonal strains of the unknown species were obtained and subjected to molecular analysis. The strains were investigated through light and scanning electron microscopy, coupled with molecular analysis of SSU rRNA and rbcL gene sequences. The features of sexual reproduction of the cultured specimens were studied, and traits previously unknown to representatives of Ulnaria were
