Abstract

The syntaxonomic diversity of vegetation in the upper reaches of the Enga-Yu River is described. The specificity of the vegetation in the study area was determined by the ubiquitous occurrence of ultramafic rocks, which contributed to an increase in the harshness of habitats due to the high concentration of heavy metals and the low calcium content. Unfavorable geochemical environments caused the absence of several common in this region species and in the same time the change of ecological preferences and ecological amplitude of other species. Within the lower and middle parts of the alpine belt, we distinguished and described for the first time 4 associations and 2 subassociations. Cladonio rangiferinae–Caricetum arctisibiricae ass. nov. with 2 subassociations (C. r.–C. a. typicum subass. nov., C. r.–C. a. dicranetosum acutifolii subass. nov.) we assigned to the class Loiseleurio procumbentis– Vaccinietea Eggler ex Schubert 1960. Asahineo chrysanthae–Racomitrietum lanuginosi ass. nov. is placed into the class Carici rupestris–Kobresietea bellardii Ohba 1974. Two associations were distinguished as provisional. Tephroserido tundricolae–Bistortetum ellipticae ass. prov. comprising snowbed vegetation, is not assigned yet to any higher unit. Festuco arcticae–Caricetum arctisibiricae ass. prov. comprises meadow communities, it is assigned to the class Juncetea trifidi Hadač in Klika et Hadač 1944 and order Juncetalia trifidi Daniёls 1994. It is not assigned to any alliance due to the shortage of data. The peculiarity of these provisional associations we explain by the influence of ultramafic rocks.

俄罗斯极地乌拉尔地区恩加玉河上游超镁铁山脉Rai-Iz的植被

介绍了恩加峪河上游植被的分类学多样性。研究区植被的特殊性是由超镁铁质岩石的普遍存在决定的，这些超镁铁质岩石由于重金属浓度高、钙含量低而增加了生境的严酷性。不利的地球化学环境导致了该地区几种常见物种的缺失，同时其他物种的生态偏好和生态幅度也发生了变化。在高寒带中下部，我们首次区分和描述了4个组合和2个亚组合。rangiverinae - caricium arcsibiricae . 11 .具2个亚群(c.r.c c)。A.典型的鲈鱼;11月，c.r.c。大鲵。11月11日)，我们给班级分配了Loiseleurio procumbentis - Vaccinietea Eggler ex Schubert 1960。Asahineo chrysanthae-Racomitrietum lanuginosi ass. 11 .被归入Carici rupestris-Kobresietea bellardii Ohba 1974。有两个协会被认为是临时的。冬虫夏草-椭圆形长叶蛾属。包括积雪植被，尚未分配给任何更高的单位。木樨草-木樨草属植物。包括草甸群落，它被分配到Juncetea trifidi hadasei在Klika et hadasei 1944和Juncetalia triidi Daniёls 1994目。由于缺乏数据，它没有分配给任何联盟。我们用超镁质岩石的影响来解释这些临时组合的特殊性。

期刊介绍： Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
