The time course of changes in characteristics of herbaceous vegetation around Formica aquilonia Yarr. ant nests formed from artificially relocated fragments of original families was studied over 6 years. At the initial stage of nest formation, species richness and diversity of the herbaceous layer decreased, and its taxonomic, spatial, phytocenotic...

Some up-to-date methods of analysis of the spatial and age structures of populations, including local population density maps and Ripley’s functions, are described using 20 cenopopulations (CPs) of Adonis vernalis L. as an example. Pregenerative plants have been found to be the most contagious, irrespective of climatic and phytocenotic conditions a...

Landscape-climatic changes are described that took place in the second half of the Late Neopleistocene and Holocene on the eastern macroslope of the Northern Urals. On the basis of geochronological and palynological data, the composition of paleocommunities in different time sections over the past 50000 years has been reconstructed in detail. Paleo...

Landscape-geochemical features providing for manifestation of gigantism in herbaceous plants have been revealed in natural habitats in the south of Sakhalin and Kunashir islands. Tall herb assemblages have proved to be associated with geochemical landscapes characterized by reducing (gley or hydrogen sulfide) conditions and increased contents of pe...

Long-term monitoring of mountain birch populations (1992–2006) was performed in 14 test plots located at distances of 1 to 63 km from the copper-nickel smelter in Monchegorsk (Murmansk oblast) and differing in the degree of disturbance. In the period from 1999 to 2006, atmospheric emissions of sulfur dioxide and heavy metals amounted to only one-th...

The aboveground phytomass of meadow plants and the density of chortobiont invertebrates in secondary upland meadows were estimated using a biocenometer in three areas differing in the level of pollution with emissions from the Middle Ural Copper Smelter (Revda, Sverdlovsk oblast) in 2006 and 2007. As the smelter is approached, the total amount of p...

Different components of group effect on the locomotor activity of single common toad and brown frog tadpoles have been studied by estimating the length of their trajectories, the speed of movement, the number of crossings of experimental field zones, and the number and duration of stops. The results show that toad tadpoles are more active than frog...

Bryoindication mapping was performed on the basis of synthetic poleotolerance indices for 147 test plots in the city of Bryansk (the southwestern nonchernozem zone of Russia). Individual poleotolerance coefficients of bryophytes were determined. Changes in the state of the atmosphere in the city ecosystem over 12 years were analyzed.

Specific features of biocenotic self-regulation of productivity and phytomass quality in mixed agrocenoses with perennial broadleaf herbs in the mountain zone were analyzed experimentally. The dynamics of phytomass accumulation and decomposition and the course of succession were determined in an agrocenosis constructed on the model of plant communi...
