Abstract

This paper discusses the abundance and morphogenetic parameters of the species Adonis villosa Ledeb., which is vulnerable in the Altai Republic (AR). Genetic differentiation has been identified in six A. villosa coenopopulations (CPs) using ISSR markers and the variability of its morphometric parameters has been determined in individuals from four CPs inhabiting the AR for the first time. It is established that the studied CPs are similar in variability of morphometric parameters, and the number of mature generative individuals in them has decreased 1.5–2.0 times over the period from 2017 to 2023. The genetic structure is examined using six primers: M 9, UBC 834, UBC 830, UBC 857, UBC 840, and UBC 811; UBC-857 turned out to be the most informative one. Four variants of the distribution of ISSR markers are identified in representatives of the six studied A. villosa CPs that feature a high (88–99%) similarity in the distribution of ISSR markers. Intrapopulation similarity between individuals of this species is also high (97%). Apparently, this is due to the small numbers of mature generative individuals (up to ten) in the studied CPs and their spatial isolation. In the Northern Altai region, A. villosa individuals feature a homogeneous genetic structure, which makes this species vulnerable and necessitates a special approach to its conservation.

阿勒泰共和国Adonis villosa Ledeb.(基于 ISSR 标记的阿尔泰共和国 Adonis villosa Ledeb.

摘要本文讨论了阿尔泰共和国（AR）易受侵害的物种Adonis villosa Ledeb.的丰度和形态发生参数。利用 ISSR 标记确定了六个 A. villosa 同群（CPs）的遗传分化，并首次测定了栖息在阿尔泰共和国的四个同群个体的形态参数变异性。结果表明，所研究的 CP 在形态参数的变异性方面具有相似性，在 2017 年至 2023 年期间，这些 CP 中成熟个体的数量减少了 1.5-2.0 倍。使用六种引物对遗传结构进行了研究：M 9、UBC 834、UBC 830、UBC 857、UBC 840 和 UBC 811；其中 UBC-857 的信息量最大。在所研究的六个 A. villosa CPs 中，发现了 ISSR 标记分布的四个变体，它们的 ISSR 标记分布具有高度（88-99%）的相似性。该物种个体间的种群内相似度也很高（97%）。显然，这是由于在所研究的 CP 中，成熟的生成个体数量较少（最多 10 个），而且它们在空间上相互隔离。在北阿尔泰地区，A. villosa 个体的遗传结构具有同质性，这使得该物种非常脆弱，有必要对其采取特殊的保护措施。

期刊介绍： Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
