Abstract

We studied tussock communities with Eriophorum vaginatum attributed to the class Oxycocco-Sphagnetea Br.-Bl. et Tx. ex Westhoff et al. 1946 and predefined class Carici arctisibiricae–Hylocomietea alaskani class. prov. (Matveyeva & Lavrinenko 2021) Two new associations – Ledo decumbentis–Eriophoretum vaginati Lapshina ass. nov. (with 3 variants) and Pleurozio schreberi–Eriophoretum vaginati Lavrinenko et Lavrinenko ass. nov. (with subassociations typicum, shagnetosum lenenses, and sphagnetosum russowii) have been described in the bog class. The first association is confined to the southern tundra subzone of the West Siberian sector of the Arctic, while the second one to the East European sector of the Arctic, where the subassociations alternate along a gradient from the north of the typical tundra subzone to the south of the southern tundra subzone. The new association Arctagrostio latifoliae–Eriophoretum vaginati Lavrinenko O. et Lapshina ass. nov. has been categorized as zonal tundra vegetation. We compared these associations with syntaxa of the communities with Eriophorum vaginatum that were previously described in bog and zonal positions in the Siberian Arctic and Alaska.

俄罗斯北极地区与阴道草的新关联

本文研究了隶属于氧可可类(Oxycocco-Sphagnetea Br.-Bl)的阴道绒螟(Eriophorum vaginatum)群落。et x. ex Westhoff et al. 1946和预定义类Carici arctisibiricae-Hylocomietea alaska class。箴言。(Matveyeva & Lavrinenko 2021)两个新的协会- Ledo decumbentis-Eriophoretum vaginati Lapshina ass11(3个变种)和Pleurozio schreberi-Eriophoretum vaginati Lavrinenko et Lavrinenko ass11(与亚协会typicum, shagnetosum lenenses和sphagnetosum russowii)在bog类中被描述。第一种关联局限于北极西西伯利亚地区的南部冻土带，而第二种关联则局限于北极的东欧地区，在那里，亚关联沿着从典型冻土带北部到南部冻土带南部的梯度交替存在。新类群Arctagrostio latifoliae-Eriophoretum vaginati Lavrinenko O. et Lapshina assa . 11被归类为地带性冻土带植被。我们将这些关联与先前在西伯利亚、北极和阿拉斯加的沼泽和地带性位置描述的阴道疣群落的句法群进行了比较。

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.
