The accumulation of heavy metals by wild mushrooms in the Kaliningrad region
This article considers the heavy metal accumulation capacity of wild mushroomson on the basis of calculating the concentration and biological uptake coefficients. An analysis of these data shows that some mushroom species have a high selective capacity for cadmium (B. edulis) and zinc accumulation (R. decolorans) independent of the concentration of these elements in the substrate. A higher concentration of heavy metals was detected in the Russulaceae picked on the Sambia peninsula in comparison to...
The history and modern condition of the urban fieldfare (Turdus pilaris L.) population in Kaliningrad
This article examines the history of formation of fieldfare population in Kaliningrad and describes its current condition. The fieldfare population density during the 2010—2013 nesting period was 0—1.5 breeding pairs/10 hecares in urban forests, 1.1—3.7 b. p./10 ha in city parks, and; 0—1 b. p./10 ha in city streets. The dynamics of nesting density in peripheral abandoned parks is characterized by a clear negative trend, whereas, in cultivated city parks, nesting density has significantly increased...

On the content of heavy metals in the soils of Kaliningrad urbanised ecosystems
This article studies the quantitative content of heavy metals in the soils of Kaliningrad urban ecosystems. It is shown that urban soils are heavily contaminated with zinc and lead with an at least threefold excess of the TLV. The concentration of copper, nickel, and cobalt is closer to the TLV. The authors emphasize that heavy metal concentrations in the soils of Kaliningrad urban ecosystems vary significantly depending on the year and territory.

Peculiarities of zooplankton succession depending on the landscape and the genesis of the lake basin (on ex-ample of some lakes of the Pskov Oblast)
On the basis of 1948—2011 materials, this article characterises the zooplankton of three large lakes of similar age and origin found at different trophic stages and in different landscapes of the Pskov region. It is shown that the structural features of the organization and direction of succession of zooplankton communities are directly dependent on the landscape and genesis of the lake basin and, in their turn, can be used as an indicator of the successional stage of the aquatic ecosystem.

The environmental aspects of the great cormorant’s (Phalacrocorax carbo L.) nest location on the coast of the Curonian Lagoon of the Baltic Sea
This article explores the features of the cormorant’s nest locations on alder at two breeding colonies on the coast of the Curonian Lagoon. Based on an analysis of over 10,000 nests, three types of nest locations were identified:forks of tree trunks and large branches, medium-sized crown branches, and tops of broken trunks. It is shown that, in older and more numerous colonies, nests are located much lower, whereas the variability in nest distribution reaches it maximum. In the newly formed small...
Steroid hormone in marine bivalve molluscs of the annual cycle
This article describes the features of quantitative distribution of glucocorticoid steroid hormones — hydrocortisone and corticosterone – at different stages of the life cycle of the Mediterranean mussel (Mytilus galloprovincialis) and the European flat oyster (Ostrea eduliss). The author identifies a common pattern of hormone dynamics consisting in a reduction in the level of hormones in molluscs in the course of maturation. Interspecies differences in the ratio of hormone levels are described....

This article argues that, in the estuaries the South Baltic, the bivalve molluscs Mya arenaria are capable of consuming an average of 6.5 % of the water body primary production. A numerical assessment of the filtration rate of these molluscs shows that they can filter daily an average of 2.41 ± 1.01 m3 of water per a square meter of the river bed. During the vegetation season, molluscs can clear approximately 380 m3 of water in estuaries removing up to 558.9 ± 65.7 g of suspended organic matters...
