Abstract—

The results of large-scale grid mapping of relict plant species (Anemone altaica Fisch. ex C.A. Mey., A. baicalensis Turcz., Corydalis bracteata (Steph.) Pers., Eranthis sibirica DC., Primula pallasii Lehm., and Waldsteinia ternata (Steph.) Fritsch) within the nemoral refugium on the northern slope of the Khamar-Daban Ridge (the Republic of Buryatia) are given. Mapping was carried out in the lower part of the Bolshoi Mamai River basin in a model area (25 km²). The research results have confirmed the general pattern for South Siberian nemoral relics, namely, their confinement to valleys and banks of rivers and streams. At the same time, the studied species differ in their habitat preferences, including their ability to spread beyond river valleys, the range of preferred altitudes, and their resistance to disturbance of vegetation. Cluster analysis and assessment of species relationships using the nonparametric Kendall concordance coefficient have confirmed concordant spatial distribution patterns of the model species.

摘要-

匍匐植物物种（Anemone altaica Fisch. ex CA Mey.、A. baicalensis Turcz.、Corydalis bracteata (Steph.) Pers.、Eranthis sibirica DC.、Primula pallasii Lehm. 和Waldsteinia ternata）的大规模网格制图结果(Steph.) Fritsch) 位于 Khamar-Daban Ridge（布里亚特共和国）北坡的 nemoral 避难所内。绘图是在 Bolshoi Mamai 河流域的下部模型区（25 km ²）。研究结果证实了南西伯利亚nemoral遗迹的一般模式，即它们被限制在山谷和河流和溪流的堤岸。同时，所研究的物种在栖息地偏好方面有所不同，包括它们在河谷之外传播的能力、首选海拔的范围以及它们对植被干扰的抵抗力。使用非参数 Kendall 一致性系数对物种关系进行聚类分析和评估，已确认模型物种的空间分布模式一致。
