Academic literature on the topic 'Vaccinio-Piceetea'

The two new associations of the feathermoss coni­ferous boreal forest, Equiseto scirpoidi—Piceetum obovatae (all. Piceion excelsae) and Zigadeno sibirici—Pinetum sylvestris (all. Dicrano-Pinion, cl. Vaccinio-Piceetea), with 2 subassociations and 5 variants are described from the water-protective zone of the Ufa Plateau (Republic Bashkortostan). The stands of the associations are restricted to steep slopes of the Ufa R. and the Pavlovsk Reservoir. The diagnoses and descriptions of all the new syntaxa are given. Floris­tically, the syntaxa are typical of the simultaneous occurrence of diagnostic species groups of the classes Vaccinio-Piceetea, Querco-Fagetea, and Brachypodio-Betuletea. This fact represents the ecotone effect action at a regional scale, as boreal, nemoral and steppe florogenetic complexes meet each other in the study area.

ZusammenfassungVorliegende Arbeit untersucht die Struktur der Assoziationen der Klasse Vaccinio‐Piceetea aus den rumänischen Karpaten. Es werden die topoklimatischen und edaphischen Bedingungen betrachtet, die zur Differenzierung in zahlreiche zönotaxonomische Gruppierungen beigetragen haben. Hier spielen neben den Gebüschen von Vaccinium myrtillus und V. vitis‐idaea Gras‐ und Moosteppiche eine gewichtige Rolle. Für jede Assoziation werden die Synonyme, die floristische Zusammensetzung und Struktur gegeben sowie die Einheiten niederen taxonomischen Ranges erwähnt.

A review of syntaxonomic information published in the journal “Vegetation of Russia” during 10-year period is given. The total amount of papers, spectrum of their authors as well as a number of relevés for each class of the Braun-Blanquet system are analyzed. The most investigated classes of the vegetation of Russia are Molinio-Arrhenatheretea, Phragmito-Magnocaricetea, Potametea, Festuco-Brometea, Vaccinio-Piceetea, Carici rupestris—Kobresietea bellardii, Querco-Fagetea, Brachypodio pinnati—Betuletea pendulae, Festuco-Puccinellietea, Juncetea trifidi. The reviews of the recently issued monographs on plant cover of Russia are cited.

This paper presents a characterization of the syntaxa of zonal dark coniferous forests dominated by Abies nephrolepis, A. sachalinensis, Picea jezoensis, P. glehnii, and P. obovata of the class Vaccinio-Piceetea Br.-Bl. in Br.-Bl. et al. 1939 and the order Abieti veitchii–Piceetalia jezoensis Miyawaki, Ohba, Okuda, Nakayama et Fujiwara 1968. The order Pinetalia pumilae Suzuki 1964, which unites thickets of Siberian dwarf pine (Pinus pumila), is also included. Each syntaxon is presented with its diagnostic taxa list, distribution, and habitat conditions. Furthermore, we validate the names of one alliance, two associations, and two subassociations of dark coniferous forests, because these syntaxa were described invalidly earlier (Vegetation…, 1988; Krestov, Nakamura 2002).

The current phytosociological diversity of dark coniferous forests in the region includes one order, three alliances, and 17 associations. In further development of the Vaccinio-Piceetea classification system, we propose dividing the azonal subalpine forests from the temperate zone and the zonal boreal forests into two orders: the order Abieti veitchii–Piceetalia jezoensis s. str. for the temperate zone in Japan and Korea, and a new order for the boreal zone. The order Vaccinio–Pinetalia pumilae Suzuki 1964, which includes the alliance Vaccinio–Pinion pumilae Suzuki 1964 and two associations, Vaccinio–Pinetum pumilae Maeda and Shimazaki ex Suzuki 1966, and Ledo–Pinetum pumilae Kobayashi 1967, unites communities dominated by Pinus pumila. The syntaxonomical concept of the order Vaccinio–Pinetalia pumilae was established based on vegetation data from Japan (Kobayashi, 1967; 1971) and should be updated with vegetation relevés from the Russian Far East.

The analysis of modern state of boreal larch forests in their main part of range placed in continental bioclimatic sector of Northern Eurasia (Siberia and continental part of Russian Far East) was performed. Conspectus of larch forests syntaxa was developed and it includes one class - Vaccinio myrtilli-Piceetea abietis Br.-Bl. in Braun-Blanquet et al. 1939, one subclass - Laricenea cajanderi-sibiricae subclass nova hoc loco, two orders - Ledo-Laricetalia cajanderi Ermakov in Ermakov et Alsynbayev 2004, Lathyro humilis-Laricetalia cajanderi Ermakov, Cherosov et Gogoleva 2002, six alliances - Ledo palustris-Laricion cajanderi Ermakov in Ermakov et Alsynbayev 2004, Pino sibiricae-Laricion sibiricae Ermakov in Ermakov et Alsynbayev 2004 (syn. Pino sibiricae-Laricion sibiricae Guinochet ex Dostalek et al. 1988 nom. nud., art. 2b, art. 8, Barkman et al., 1976, art. 2b, art. 8, Weber et al., 2000), Cladonio stellaris-Laricion gmelinii Anenkhonov et Chytry 1998, Empetro-Piceion obovatae Morozova in Morozova et al. 2008, Aulacomnio acuminati-Laricion cajanderi Ermakov Cherosov et Gogoleva 2002, Rhododendro daurici-Laricion gmelinii Ermakov in Krestov et al. 2009 and 30 associations. Diagnostic features of all syntaxa and their main ecological characteristics were represented. The problems of larch forests classification and syntaxa nomenclature were discussed. All diversity of boreal light-coniferous deciduous (larch) forests of continental bioclimatic sector of Northern Eurasia of the class Vaccinio-Piceetea was included in new subclass Laricenea cajanderi-sibiricae subclass nova hoc loco. Diagnostic species combination of the subclass includes predominating larch species ( Larix cajanderi, L. sibirica, L. gmelinii, L. decidua, L. olgensis ) and diagnostic species of the subordinated orders Ledo-Laricetalia cajanderi and Lathyro humilis-Laricetalia cajanderi .

Acest studiu prezintă diversitatea floristică a vegetației Forestiera identificată în rezervația naturală Pădurea Roșoșa. Fitocenozele identificate au fost încadrate în 3 asociații vegetale: Leucanthemo waldsteinii-Fagetum (Soó 1964) Täuber 1987, Hieracio transsylvanici-Piceetum Pawlowski et Br.-Bl. 1939, Hieracio transsylvanici-Abietetum (Borhidi 1971) Coldea 1991. Acestea aparțin la două categorii de habitate de interes comunitar Natura 2000: 91V0 – Păduri dacice de fag (Symphyto-Fagion) și 9410 - Păduri acidofile de molid (Picea) din etajul montan până în cel alpin (Vaccinio-Piceetea). Analiza comparativă a asociațiilor vegetale identificate ne relevă faptul că spectrele bioformelor, elementelor floristice și a indicilor ecologici au un grad de similaritate foarte ridicat.

We present a detailed nomenclatural analysis of the class names Carpino-Fagetea, Querco-Fagetea, Quercetea robori-sessiliflorae, Quercetea ilicis and Vaccinio-Piceetea. The current literature presents contradictory opinions about the legitimacy and correct author citation of these names, often motivated by deviating interpretations of the International Code of Phytosociological Nomenclature. This primarily concerns the provisions of Articles 2b, 3j, 3m and 35 which can be interpreted in quite different ways, leading to divergent conclusions on the validity and legitimacy of a name. Thus, the problems discussed in this paper are of general relevance for phytosociological nomenclature, highlighting the need for amendments and clarifications to be implemented in the next edition of the Code. Moreover, we suggest establishing a formal procedure to request a binding decision on specific cases to stabilise the interpretation of the Code.

The secondary birch and aspen forests of middle stages of succession of the central elevated part of the Southern Urals are studied. 4 subassociations, 1 community, and 7 variants in the alliances of Aconito-Piceion and Piceion excelsae are allocated. It is shown that the floristic composition of aspen and birch secondary forests in the age of 60—80 years is almost identical to the natural forests. However, a slight increase the coenotical role of light-requiring species of grasslands and hemiboreal forests in the secondary communities of the class Brachypodio-Betuletea was noticed as well as some reduction of role the shade-tolerant species of nemoral complex and species of boreal forests of the class Vaccinio-Piceetea. Dominant tree layer under the canopy of secondary series is marked by an active growth of natural tree species.

Results of a syntaxonomical study of the oligotrophic forests of northern European Russia are presented. The main forest types have been classified into 2 orders of the class Vaccinio-Piceetea, 4 alliances, 6 associations and 1 community. The new alliance Empetro-Piceion all. nov., which includes zonal spruce and birch northern forest association Empetro-Piceetum, has been established. These communities are formed according to cold temperature and high (sometimes temporarily) soil moisture and are characterized by the lower tree canopy, mosaic herb and moss-lichen layers with boreal mosses, sphagnum and lichens. In the middle taiga subzone these communities are replaced by Eu-Piceetum myrtilletosum. The forests with lichens are referred to order Cladonio-Vaccinietalia and divided into 4 associations. Lichen pine forests of the north-west of boreal zone were described as ass. Flavocetrario nivalis—Pinetum ass. nov. This association with a great number of lichens is differentiated by Cladonia arbuscula subsp. mitis, Flavocetraria nivalis, Cetraria ericetorum, Stereocaulon grande, Dicranum fuscescens, D. drummondii, Nephroma arcticum and species of Cladonia. The ass. Cadonio arbusculae—Pinetum (Caj. 1921) K.-Lund 1967 contains lichen pine forests with lower number of lichens and is distributed mostly in middle part of the taiga zone. The spruce-pine forests with mixed moss-lichen cover correspond to ass. Vaccinio-Pinetum. Ass. Hedysaro-Laricetum represents rich and well differentiated larch forests in the east of European Russia.

В статье представлены результаты обследования лесов, расположенных между долиной р. Курджипс и крутыми склонами куэсты хребта Каменное море. На основе 24 геоботанических описаний табличным методом Браун–Бланке выделили 3 группы сообществ, имеющих эколого-флористические различия: 1) смешанные светлохвойно–лиственные; 2) темнохвойно–лиственные; 3) лиственные леса. Предварительно они отнесены к четырем классам лесной растительности – Brachypodio pinnate–Betuletea pendulae, Vaccinio–Piceetea, Betulo carpaticae–Alnetea viridis, Carpinio-Fagetea sylvaticae. Несмотря на доступность территории, леса сохраняют реликтовые и эндемичные виды растений.

The long-term soil temperature monitoring in the area of more than 550 km in length within the region of Transbaikalia has been carried out. Sites for the monitoring were represented by the forest-steppe vegetation of different ecotopological and ecogeographical patterns. It was revealed that the dynamics of temperature regimens are highly synchronized reflecting the macroclimatic unity of the region. The sufficiently higher heat supply on the southerly exposed slopes comparing to northerly exposed ones was demonstrated. The distinctness between soil temperature regimens in different sites was revealed and attributed to the size of forested patches within the forest-steppe landscape, as well as discrepancies between eco-geographical features of sites along the sublatitudinal gradient. Differences between the vegetation types that occurred on the northern and southern slopes as well as between key sites scattered throughout the region were underlined. These differences are suggested to be connected with the spatial differentiation of the soil temperature. It was established that vegetation on the southern slopes is relatively more homogeneous being related to the single class Cleistogenetea squarrosae, while on the northern slopes plant communities related to three classes were developed, namely steppe class Cleistogenetea squarrosae, and two forest classes – Rhytidio-Laricetea and Vaccinio-Piceetea.

Огромные территории нашей страны заняты таёжными лесами, и наибольшую долю среди них составляют лиственничные леса, характерные для Восточной сибири и Дальнего Востока. Обширный ареал позволяет им занимать самые разнообразные местообитания и формировать широкий спектр сообществ. Далеко не всё это многообразие на данный момент описано, классификация разработана не для всех типов лиственничных лесов, и работа над систематизацией данных активно продолжается [1]. Одним из наиболее интересных регионов является зона контакта бореальных лиственничных лесов и геимбореальных чёрно-берёзовых и дубовых лесов Дальнего Востока. Здесь формируются сообщества амурской подтайги, в которых под пологом лиственницы доминируют виды неморального высокотравья [2, 3, 4]. Хребет Тукурингра расположен на границе их распространнения. Хотя данные из этого региона использовались в обзорных публикациях [5], инвентаризации фитоценотического разнообразия лиственничных лесов для него не было проведено. На данный момент в литературе описано 36 различных ассоциаций лиственничных лесов, в которых лесообразующей породой является Larix gmelinii s.l., и ещё девять обозначены провизорно. Цель работы — разработка классификационной схемы для лиственничных лесов и их дериватов, распространнённых на территории хребта Тукурингра, а так же демонстрация их ботанико-географических особенностей. Использованы 332 геоботанических описания, около половины из них относятся к ранее не описанным синтаксонам. Продромус содержит 11 ассоциаций, отнесённых к трём классам растительности — Querco mongolicae-Betuletea davuricae Ermakov et Petelin in Ermakov 1997, Vaccinio myrtilli-Piceetea abietis Br.-Bl. in Braun-Blanquet et al. 1939, Vaccinietea uliginosi Tx. 1955 — из них четыре ассоциации предложены провизорно. Результаты проделанной работы могут служить научной базой для последующих исследований и природохранных мероприятий, а также расширяют современные представления о разнообразии лиственничных лесов, система классификации которых с использованием эколого флористического подхода в данный момент продолжает формироваться.
