Voronezhsky nature reserve is situated in the forest-steppe zone of European Russia, on the border between Lipetsk and Voronezh regions. The reserve was estab­lished in 1923; the total area of the reserve is 31 053 ha. We have created the vegetation classification system for the reserve on basis of 1058 phytocoenotic relevés processing. Phytocoenotic relevés have been collected since 1929 by different generations of researchers. All relevés were included into the data processing. Five forest vegetation formations and one herbaceous formation were described. According to the reserve’s forest inventory from 1991, Pinussylvestris formation occupies 32.3% of the reserve area, broad-leaved forest (oak forest) formation — 29.3, Populus tremula formation — 19.3, birch forest formation — 5.7, and Alnus glutinosa formation — 5.2 correspondingly. Her­baceous formation covers 3 % of the area in dry, moderate moistened and moist soils, and swamps occupy 2.5 % of the reserve area (they are not described here). Within the bounds of the vegetation formations, we have distinguished the vegetation association groups on the basis of ground vegetation functional group composition and ordination (DCA) technique. 8 functional species groups (ecologic-coenotic species groups) were used for the classification. The ecologic-coenotic species groups were as follows: 1) nemoral, 2) boreal, 3) nitrophilous, 4) pine-forest, 5) meadow-forest edge, 6) steppe, 7) oligotrophic, and 8) water-swamp. Totally we have described 23 vegetation asso­ciation groups united into the 9 ecologic-coenotic types of vegetation cover. 4 vegetation association groups were described for the herbaceous formation. We described in detail vegetation association groups inclu­ding species, structural diversity and the ecological position calculated by Tsyganov’s ecological species values. We also discuss the group’s history and the succession status. Finally, we have compared the proposed vegetation classification system for the re­serve with some other classification systems.

The Village

The study of the nature reserve oak forest near the village of Pelya-Khovanskaya ecosystem was done in the region of Nizhny Novgorod. The investigated wood is unique for its complex structure. It is situated in the forest-steppe zone, characterized by a high species diversity of small mammals and vegetation, which indicates the complexity of trophic and spatial connections. Several series of sample plots were described: 41 of 2020 m and a number of 11 m sites, totaling 300. Abundance of species by Brown-Blanke scale and the number of specimens of adolescence were specified for each 1 sq. m. plot. Mammals were trapped with the help of trapping grooves and transects method. Vegetation cover is characterized by the presence of a clear intra-differentiation as well as the existence of two basic ecologo-coenotic groups/cores - the nemoral (with Pulmonaria obscura Dum. as the center species of the core) and the meadow-fringe. The most distinct group is formed by forest-shoot species. It can be explained by more forest-steppe rather than nemoral nature of vegetation. Small mammals are represented by the following species: common and small shrews, small forest mouse, yellow-throated and field mice and harvest mouse, vole-housekeeper, common, plowed and red voles, European mole. Two species among them - vole-housekeeper and mouse-baby - are listed in the Red Book of the Nizhny Novgorod Region. Matching burrows of mouse-like rodents with soil richness with nitrogen and humidity, two well-defined peaks are observed. The greatest number of burrows is found in places where the soil is high in nitrogen. Moles were found in areas with a large projective coating of Primula veris: coefficient Spearman rank 0,50. There was a negative correlation of the number of moles and vegetation covering of Pyrethrum corymbosum (-0,46), which is the marker of the driest parts in the forest. In general, the nature reserve oak forest near the village of Pelya-Khovanskaya is of considerable interest, both from botanical and from zoological point of view. Long-term studies of biocoenosis will allow to monitor the facility and to correct the proposed protective measures.

Ecological Functionality

The knowledge of biomes as large-scale ecosystem units has benefited from advances in the ecological and evolutionary sciences. Despite this, a universal biome classification system that also allows a standardized nomenclature has not yet been achieved. We propose a comprehensive and hierarchical classification method and nomenclature to define biomes based on a set of bioclimatic variables and their corresponding vegetation structure and ecological functionality. This method uses three hierarchical biome levels: Zonal biome (Macrobiome), Biome and Regional biome. Biome nomenclature incorporates both bioclimatic and vegetation characterization (i.e. formation). Bioclimate characterization basically includes precipitation rate and thermicity. The description of plant formations encompasses vegetation structure, physiognomy and foliage phenology. Since the available systems tend to underestimate the complexity and diversity of tropical ecosystems, we have tested our approach in the biogeographical area of the Neotropics. Our proposal includes a bioclimatic characterization of the main 16 Neotropical plant formations identified. This method provides a framework that (1) enables biome distribution and changes to be projected from bioclimatic data; (2) allows all biomes to be named according to a globally standardized scheme; and (3) integrates various ecological biome approaches with the contributions of the European and North American vegetation classification systems.

Abstract Aims The latest China Vegetation Classification System (China-VCS) for natural/semi-natural vegetation has eight hierarchical levels: Association < Association-group < Subformation < Formation < Formation-group < Vegetation-subtype < Vegetation-type < Vegetation-type-group. The classification is based on dominant species and their growth forms and has been completed at the formation level. The principal challenge today in Chinese vegetation classification is to develop the China-VCS at levels below the formation in a way that is consistent with current international standards. We explored the following question: how can existing vegetation plot data help develop the China-VCS and improve its compatibility with other international classification systems? Methods We compiled 401 plots having plant cover and/or aboveground biomass measurements collected in six Stipa steppe formations and divided them into those with cover data (299 plots) and/or biomass data (283 plots). We applied a combination of hierarchical clustering and ordination to partition the cover and biomass data sets into formations and constituent associations. We then used supervised noise clustering to improve the classification and to identify the core plots representing each association. Diagnostic species were also identified at both association and formation levels. Finally, we compared the classification results based on cover and biomass data sets and combined these results into a comprehensive classification framework for the six formations. Important Findings Our results using cover data were comparable with those using biomass data at both formation and association levels. Three Stipa formations were classified into associations based on cover data, two based on biomass data and one based on both biomass and cover data. Twenty-seven associations were defined and proposed within the six formations, using cover or biomass data as consistent classification sections (CCSs). Both dominant species in the dominant stratum and diagnostic species from multiple strata of the core plots were used to characterize vegetation types at both formation and association levels, improving the compatibility of our classification with the International Vegetation Classification. Temperature and precipitation were found to be important climatic factors determining the distribution pattern and species composition of Stipa-dominated vegetation. We propose a framework for plot-based vegetation classification in the China-VCS, using our work with Stipa-dominated steppe vegetation as an example. We applied the concept of CCS to make optimal use of available data representing both plant cover and biomass. This study offers a model for developing the China-VCS to the association level in a way that is consistent with current international standards.

283 The purpose of this research was to study interspecific and intra-specific aggressive reactions of Robins (Erithacus rubecula L.) at watering places in natural and anthropogenically pressured areas. The study took place in Kaniv Nature Reserve, Cherkassy region, in May-June 2010, 2012 and 2014 and the state dendrology park “Oleksandriya” of the National Academy of Science in Bila Tserkva. The observation of the birds’ behavior was performed using the ethological methods of “total observation” and “continuous logging”. In order to calculate the critical distance at which a bird shows aggression, the watering areas studied were divided into 1 x 1 m squares. It was found that aggressive intersspecific actions of Robins were more frequent in the natural habitat of Kaniv Reserve while intraspecific aggression was more frequent in the dendrology park. It was noticed that Robins responded aggressively to 12 species of birds in the Kaniv Natur Reserve site. Those species were: Song Thrush (Turdus philomelos), Blackbird (T. merula), Great Tit (Parus major), BlueTit (P. caeruleus), Marsh Tit (P. palustris), Chaffinch (Fringilla coelebs), Hawfinch (Coccothraustes coccothraustes), Icterine Warbler (Hippolais icterina), Wood Warbler (Phylloscopus sibilatrix), Blackcap (Sylvia atricapilla), Collared Flycatcher (Ficedula albicollis) and Spotted Flycatcher (Muscicapa striata). Most often, aggression was directed to individuals that were already at a watering place rather than birds which arrived after the Robins. Besides, Robins frequently initiate aggressive relations. An inverse correlation of aggressive acts and the size parameters of the species, which were objects of Robins’ aggression, was observed. A success rating of Robins’ defence and attack in aggressive relations in Kaniv Nature Reserve was established: Robins were always successful in protecting its territory or attacking an Icterine Warbler and Chiffchaff, and always fails in defending agianst or attacking a Blackbird. The rating in contact with Spotted Flycatcher was zero. The critical distance of aggressive behaviour in intraspecific contacts at watering places was 40–50 cm, while for interspecific contacts it varied from5 cm to2 m. Our research emphasizes the importance of long-term research and multivariate approaches for understanding the complexity of dominance relations in birds.

This paper presents data on the new location of the moss Ptilium crista-castrensis (Hedw.) De Not, which is listed in the Red Data Book of the Samara Region on the territory of the nature reserve Racheyskie Rocks in the Syzran district. 10 of its coenopopulation loci have been identified and the exact geographic coordinates are given. For the first time the exact coordinates of 11 coenopopulation loci are also named for the holarctic mountain-forest relict fern Polypodium vulgare L., which is also protected at the regional level, both of these species have a mosaic structure of coenopopulations confined to confluent sandstones as a substrate for growth. It has been revealed that the ecological preferences of these species are very close, however, Polypodium vulgare is more shade-tolerant and it can be called a scioheliophyte, in contrast to the heliophyte Ptilium crista-castrensis . The Polypodium requires more humid and shaded conditions for its normal existence. When growing in the forest-steppe zone, where humidity is often a limiting factor, Ptilium crista-castrensis and Polypodium vulgare can form a significant projective cover (more than 30%) only in the northern and northeastern exposures of the substrate, but only with an enhanced light regime in the phytocoenosis at the density of the stand that is not more than 0,3.

Steppe Communities

Landscapes of the Northern Kazakhstan and southern part of the West Siberian Plain are deeply transformed and fragmented as a result of long-term agricultural exploitation. So, steppes became the most endangered ecosystems due to total ploughing of zonal soils. Presently, there are no large massifs of natural steppes. This determines the importance of data representing zonal steppe communities. One of the most important studies in this field is the publication by T. I. Isachenko and E. I. Rachkovskaya (1961), containing detailed characteristic of steppe vegetation from the Northern Kazakhstan and 199 relevés representing the unique dataset of zonal communities, which were destroyed later. Based on these data, Miloslav Toman (1969) has described the new order Helictotricho-Stipetalia, 2 alliances, 3 suballiances and 8 associations. He used only 40 of 199 original relevés, that led to some incorrect conclusions. This study presents the analysis of 199 steppe relevés from the publication in question. We used the following methods: (1) the table sorting; (2) numerical analysis using plant indicator values, (3) Detrended Correspondence (DCA). All relevés were assigned into the order Helictotricho-Stipetalia Toman 1969 (Festuco-Brometea Br.-Bl. et Tx. ex Soó 1947) that represents the typical bunchgrass steppes and some variants of meadow steppes. They are distributed across the northern part of steppe zone and the southern part of forest-steppe zone from the Southern Urals to Altai Mountains. The analysis showed that classification systems of steppe vegetation proposed by T. I. Isachenko and E. I. Rachkovskaya and M. Toman are not conflicting due to the fact that in both surveys plant communities were identified based upon species composition. The actual syntaxonomy of the order Helictotricho-Stipetalia can be successfully applied to the vegetation studies of large areas.
