“…ma capillaceum that forms pure mats, sometimes quite abundant, on the bases of trees and shrubs. DISCUSSION This study of vegetation communities with Dichelyma capillaceum in the Nature Park "Kondinskie Lakes" shows that the habitat and vegetation characteristics of this moss species are generally similar in West Siberia and Western Europe (Hylander, 1998;Hedenäs et al, 1996). The detailed characterization of the ecological conditions of Dichelyma capillaceum in the Nature Park has become possible due to long-term monitoring of the water level dynamics and chemical composition of lake and river waters.…”

“…Until recently Dichelyma capillaceum was referred to the group of boreal species with a well-defined amphiatlantic distribution (Toivonen, 1972;Hedenäs et al, 1996). Further floristic explorations in the European part of Russia and West Siberia expanded the distribution of this rare European species to the East (Czernyadjeva & Ignatova, 2013).…”

“…It occupies rocks, the base of trees and shrubs, roots and tree branches near water courses, the banks of lakes, ponds and slow rivers with high amplitude of the water level (annual variation between 0.6-1 m) (Hedenäs et al, 1996;Hylander 1998). Most localities are periodically flooded by water poor in nutrients, but it can also be found in more eutrophic conditions at relatively high pH levels, between 6.5 and 7.0 (Ludwig & Weddeling, 2003).…”

“…In North America almost 25% of all the studied specimens contain sporophytes (Ireland, 1989); however both female and male plants are similarly frequent (Hedenäs et al, 1996). On the contrary in Western Europe sporophytes of Dichelyma capillaceum are quite rare.…”

Ecological conditions and phytocenotic characteristics of Dichelyma capillaceum habitats in the Nature Park "Kondinskie Lakes" (Khanty-Mansiysk Autonomous District, West Siberia -60°54' N; 63°30' E) are described based on a geobotanical survey. Unlike the previous finds of Dichelyma capillaceum in Russia this locality is represented by several collections and multiple records of the species. Nineteen vegetation relevйs with Dichelyma capillaceum are analyzed. It is noted that the habitats of this species in West Siberia are similar to those in Western Europe. The habitats in both Europe and Siberia have a strongly variable water level (amplitude up to 1.0 m). The main distinctions are the low amounts of nutrients in river and lake waters in Siberia (nitrogen: NO 3 -=0.32-0.76 mg/l, NO 2 -=0-0.06 mg/l, NH 4 + =0.6-0.8 mg/l; phosphorus: PO 4 3-=0.05-0.15 mg/l), the low mineral levels (total sum of ions is 32.7 -43.7 mg/l), and the relatively acid water (pH=5.1-5.8). The collections from the study area lack sporophytes. However, the frequency and abundance of Dichelyma capillaceum in suitable habitats suggests that the asexual reproduction is rather efficient, which allows us to assume a wider distribution of the species in West Siberia. РезюмеСообщается об особенностях произрастания и экологических условиях местообитаний Dichelyma capillaceum в природном парке «Кондинские озера» (Ханты-Мансийский автономный округ, Западная Сибирь -60°54' N; 63°30' E). В отличие от всех предыдущих находок Dichelyma capillaceum в России это местонахождение представлено многократными сборами и регистрациями вида. Приведено 19 полных геоботанических описаний растительных сообществ с участием Dichelyma capillaceum. Отмечено, что в целом местообитания и характер произ-растания этого вида мха в Западной Сибири сходны с таковыми в Западной Европе. Общим является довольно большая амплитуда перепада уровня воды (до 1.0 м). Основное отличие заключается в крайней бедности речных и озерных вод биогенными элементами (азот: NO 3 -=0.32-0.76 mg/l, NO 2 -=0-0.06 mg/l, NH 4 + =0.6-0.8 mg/l; .фосфор: PO 4 3-=0.05-0.15 mg/l) и их низкой минерализации (общая сумма ионов 32.7 -43.7 mg/l) при слабо кислой реакции среды (pH=5.1-5.8). Спорофитов мха в районе исследования не обнаружено. Однако, судя по частоте встречаемости и обилию Dichelyma capillaceum во всех подходящих по условиям произрастания растительных сообществах, вегетативный способ размножения является весьма эффективным, что позволяет ожидать более широкое распространение этого вида в Западной Сибири.

“…However, in 1978 D. capillaceum was recorded from the Munţii Retezat in the Southern Carpathians in Romania (Blockeel et al, 2003). In Europe, D. capillaceum has the main centre of its occurrence in Fennoscandia, where it is particularly frequent in southern Sweden (Hedenäs et al, 1996;Hallingbäck, 1998;Hylander, 1998). In contrast, the species is widely scattered but localised in southern and central Finland (Toivonen, 1972) and it is considered to be endangered in this country (Sallantaus, 2009).…”
