Bryophyte vegetation of Bashkiria, South Urals. II. Epiphytic and epixylic communities of north-eastern Bashkiria

Abstract

The bryophytic communities of NorthEastern Bashkiria were studied. The paper presents 5 syntaxa, including two new associations for Bashkiria: Platygyrietum repentis Le Blanc 1963 and Orthotrichetosum speciosi (Jaggli 1934) Barkman 1958. Three subassociations are described as new. The diagnostic species of high syntaxa often have been used for the establishment of the Urals associations, since the floristic composition of epiphytic and epixylic communities in Bashkiria are rather poor in number of species. Резюме Были изучены сообщества мохообразных северо-восточной части Башкирии. Представлена характеристика 5 синтаксонов, в том числе две новые для Башкирии ассоциации Platygyrietum repentis Le Blanc 1963 и Orthotrichetosum speciosi (Jaggli 1934) Barkman 1958. Впервые описаны также 3 субассоциации. Для выделения многих ассоциаций использованы диагностические виды высших единиц, что связано с общей обедненностью бриофлоры Башкирии.

Bryophyte vegetation of Bashkiria (South Urals). III. Epiphytic and epixylic communities of Western Bashkiria

“…Probably, these communities are represented consecutive studies of succession. CONCLUSION In comparison with analogs known from forest and mountain zones of Bashkiria (Baisheva et al, 1994;Baisheva, 1995) epiphytic and epixylic moss vegetation of investigated area is rather poor in floristic composition and diversity of syntaxa. Presented communities have more xerophilous character reflected by lower mean number of species in releves, scarce abundance and constancy of hepatics.…”

“…They were found on the bark of Tilia cordata, Betula pendula, rarely also on rotten wood. In comparison with analogs described in North-Eastern Bashkiria (Baisheva, 1995) they have poor floristic composition (mean number of species in releve in the West Bashkiria is 3, in the North-East Bashkiria -7) and low constancy of hepatics.…”

“…In comparison with analogs known from North-Eastern Bashkiria (Baisheva, 1995) they have poor floristic composition. Mean number of species in releves in communities of Western Bashkiria is 4, in those of North-East -7.…”

Peculiarities in bryophyte communities in the Ukrainian forest-steppe

“…Баїшевої [БАИШЕВА и др. 1994;ВAISHEVA et al, 1994;ВAISHEVA, 1995] Беручи до уваги вище наведене, вважаємо необхідним подати власні погляди на розуміння мохових бріоугруповань, їх класифікацію та роль в структурі мохового покриву Лісостепу України, що грунтуються як на аналізі літературних даних, так і на результатах оригінальних досліджень. Вивчаючи моховий покрив Лісостепу України, ми відмічаємо його неоднорідність.…”
