We used a fragment of mtDNA control region (255 bp) and also included previously detected haplotypes from NCBI. Six haplotypes were found in 75 samples from European part of Russia and Transcaucasian countries. Lut1 was the most common haplotype (62.1% of samples), Lut4 was detected in 17.6% of samples, other 4 haplotypes were newly detected. Haplotype diversity for European part of Russia and Transcaucasian countries were <italic>h</italic> = 0.56 ± 0.054, nucleotide diversity were π = 0.0016 ± 0.002. When we elongated the fragment of mtDNA (820 bp), haplotype (0.85 ± 0.03) and nucleotide diversity (π = 0.002 ± 0.001) were increased and 14 haplotypes were found. Geographic distribution of haplotypes depends neither on region, nor on river system. Central haplotype was detected throughout European part of Russia and Transcaucasian countries, as well as minor haplotypes, observed in lesser number of regions. Therefore, genetic diversity of Eurasian otters from European part of Russia and Transcaucasian countries is higher than in the rest of Europe. Besides, the population structure repeats European pattern with several regional features.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324373888">Проведен анализ генетической структуры группировок выдры европейской части России (ЕЧР) и ее сравнение с известной по литературным данным генетической структурой выдры в Европе. Проанализированы данные на основе гаплотипов фрагмента контрольного региона мтДНК (255 пн), в том числе представленных в NCBI. Для выборки (<italic>N</italic> = 75) из европейской части России описано шесть гаплотипов мтДНК. 62.1% животных принадлежат общему европейскому гаплотипу, 17.6% – гаплотипу, отмеченному в Великобритании и Финляндии, остальные четыре гаплотипа описаны впервые. Гаплотипическое разнообразие для выборки по России и Закавказью составило <italic>h</italic> = 0.56 ± 0.054, нуклеотидное разнообразие π = 0.0016 ± 0.002. При увеличении длины фрагмента мтДНК до 820 пн у выдр из ЕЧР наблюдается увеличение как гаплотипического разнообразия <italic>h</italic> до 0.85 ± 0.03, так и нуклеотидного π = 0.002 ± 0.001, число гаплотипов увеличилось до 14. Географическое распределение гаплотипов не зависит ни от региона, ни от системы рек. Имеется как центральный гаплотип, распространенный по всей ЕЧР, так и второстепенные, объединяющие меньшее число регионов. Таким образом, генетическое разнообразие выдры ЕЧР выше, чем в Европе, при этом структура популяций повторяет общеевропейский паттерн, но с региональными особенностями.</p></trans-abstract><kwd-group xml:lang="en"><kwd><italic>Lutra lutra</italic></kwd><kwd>mitochondrial DNA</kwd><kwd>control region</kwd><kwd>genetic diversity</kwd><kwd>European part of Russia.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd><italic>Lutra lutra</italic></kwd><kwd>митохондриальная ДНК</kwd><kwd>контрольный регион</kwd><kwd>генетическое разнообразие</kwd><kwd>европейская часть России.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Гимранов Д.О., Косинцев П.А.
