Abstract

One of the most abundant fish species, Rutilus rutilus, is widely distributed in Lithuania and its potential to adapt to environmental changes attracted our interest. Unfortunately, it is not properly understood how anthropogenic activities can affect the genetic diversity within this species. We studied three populations of roaches (samples collected in the Neris and Žeimena rivers, and Lake Drūkšiai) over a period of five years (from 2017 to 2022) to determine genetic diversity using mtDNA D-loop and ATP6 genetic markers. Genetic diversity parameters, AMOVA analysis, haplotype network, and PCoA analysis revealed a greater genetic variability in roach samples collected in 2017, and the greatest differences were noticed in the population inhabiting Lake Drūkšiai, as compared with other samples studied over a five-year period. Differences in genetic diversity detected after a five-year period led us to the assumption that roach populations may be related to the effects of natural (changing climatic conditions) and anthropogenic (operating nuclear power plant) origin.

人类活动背景下立陶宛Rutilus Rutilus种群遗传多样性的mtDNA标记研究

最丰富的鱼类之一Rutilus Rutilus广泛分布在立陶宛，其适应环境变化的潜力引起了我们的兴趣。不幸的是，人类活动如何影响这个物种的遗传多样性还没有得到正确的理解。我们研究了三个蟑螂种群(样本收集于Neris和Žeimena河流以及Drūkšiai湖)，为期五年(2017年至2022年)，使用mtDNA D-loop和ATP6遗传标记确定遗传多样性。遗传多样性参数、AMOVA分析、单倍型网络和PCoA分析显示，2017年收集的蟑螂样本存在更大的遗传变异性，与5年期间研究的其他样本相比，居住在Drūkšiai湖的种群差异最大。五年后发现的遗传多样性差异使我们假设蟑螂种群可能与自然(不断变化的气候条件)和人为(运行的核电站)起源的影响有关。

期刊介绍： Diversity (ISSN 1424-2818) is an international and interdisciplinary journal of science concerning diversity concept and application, diversity assessment and diversity preservation. It is focused on organismic and molecular diversity. It publishes reviews, regular research papers and short notes in the regular issues. Related news and announcements are also published. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. Full experimental details must be provided so that the results can be reproduced.
