Исследованы ДНК повторы, присутствующие в геномных библиотеках с низким покрытием (0.1–0.5) четырех видов амфипод, эндемичных для озера Байкал (Восточная Сибирь), и четырех эндемичных видов брюхоногих моллюсков семейства Baicaliidae. Для этого были построены деревья методом объединения ближайших соседей для каждого квартета видов (амфиподы и моллюски) на основе соотношения повторяющихся классов, общих для каждой пары видов. Топология этих деревьев была сопоставлена с филогениями, полученными для тех же видов на основе сцепленных белок-кодирующих митохондриальных нуклеотидных последовательностей. У всех проанализированных видов в долю повторов ДНК вовлечено около половины генома. У относительно более древних амфипод (самый последний общий предок, MRCA, существовал приблизительно шестьдесят миллионов лет назад) наиболее распространенными были видоспецифичные повторы, тогда как у гораздо более молодых байкалиид (MRCA приблизительно равен трем миллионам лет) большинство повторов ДНК были общими для всех четырех видов. Если наличие/отсутствие повтора рассматривать как отдельный независимый признак, а отношение общего числа повторов в паре видов использовать в качестве меры расстояния, топология дерева NJ такая же, как и филогения квартета, выведенная для белков митогеномов, кодирующих нуклеотидные последовательности. Между тем в каждой группе видов было обнаружено значительное количество повторов, указывающих на возможность ненейтральной эволюции или горизонтального переноса между видами, занимающими один и тот же биотоп. Эти повторы были общими для неродственных групп, но отсутствовали в сестринских геномах. С другой стороны, в таких случаях некоторые черты, имеющие экологическое значение, также были общими.

DNA repeat composition of low coverage (0.1–0.5) genomic libraries of four amphipods species endemic to Lake Baikal (East Siberia) and four endemic gastropod species of the fam. Baicaliidae have been compared to each other. In order to do so, a neighbor joining tree was inferred for each quartet of species (amphipods and mollusks) based on the ratio of repeat classes shared in each pair of species. The topology of this tree was compared to the phylogenies inferred for the same species from the concatenated protein-coding mitochondrial nucleotide sequences. In all species analyzed, the fraction of DNA repeats involved circa half of the genome. In relatively more ancient amphipods (most recent common ancestor, MRCA, existed approximately sixty millions years ago), the most abundant were species-specific repeats, while in much younger Baicaliidae (MRCA equal to ca. three millions years) most of the DNA repeats were shared among all four species. If the presence/absence of a repeat is regarded as a separate independent trait, and the ratio of shared to total numbers of repeats in a species pair is used as the measure of distance, the topology of the NJ tree is the same as the quartet phylogeny inferred for the mitogenomes protein coding nucleotide sequences. Meanwhile, in each group of species, a substantial number of repeats were detected pointing to the possibility of non-neutral evolution or a horizontal transfer between species occupying the same biotope. These repeats were shared by non-sister groups while being absent in the sister genomes. On the other hand, in such cases some traits of ecological significance were also shared.
