The dumped waste from the industrial complex still threatens the biosphere. The solution to the problem lies in integrated research and the resumption of plant operation accompanied by complete waste utilization and extraction of all commercial components.
The specific features of mammals' behaviour in response to external information is determined by innate mechanisms and experience acquired through ontogenesis. The author genetically defines the unstable boundaries of behavioural responses and offers a methodology of research on quantitative animal-habitat interaction. The article emphasises the variability of behavioural
parameters in the course of the adaptation of the carnivorous to anthropogenic conditions.
This article offers the results of research on the influence of environmental factors on the distribution of two abundant bivalve species – Macoma balthica and Mytilus eduli – in the south-east of the Baltic Sea. First of all, the distribution of species was determined by the types of soils. The distribution of molluscs in deep-water sectors was limited by oxygen deficiency in near-bottom waters.
The moss biomonitor technique was employed to study heavy metal precipitation in the Kaliningrad region. Graphical data interpretation, correlation and factor analysis helped distinguish the anthropogenic and natural components in moss pollution.
This article addresses the physical, biogeochemical and physiological factors in the framework of marine invertebrate biodiversity problem. The comparison of the biodiversity indicators of fossils and modern organisms is considered as the crucial method of the reconstruction of alterations in populations and ecosystems.
This article considers the response of hydrobionts to exogenous biologically active substances of natural (BASn) and anthropogenic (BASa) origin, the peculiarities of BASn functional spectrum in eukaryotes of different taxons, and the damaging impact of BASa both at an organism and an ecosystem level.
This article considers the applicability of biotesting methods to the analysis of wastewater toxicity through the example of Sterlitamak Petrochemical Plant. The offered biotesting method helps estimate total wastewater toxicity. The estimation of phytotoxicity was based on the following parameters of the watercress (Lepidum sativum (L.)): sprout growth, biomass accumulation, and seed sprouting.
The maximum individual age of the Japanese littleneck clam is 7 years. The maximum shell length is 5.2 mm. The sex ratio is almost 1 to 1. There are registered cases of hermaphroditism and parasitic castration. The rate of linear growth has increased to three years. The molluscs reach the harvestable size in three years.
This article offers data on chironomid fauna in two lakes in the city of Kaliningrad: Lake Penkovoye and Lake Isakovskoye.
The authors analyse the species composition as well as ecological characteristics of populations and estimate the condition of
water ecosystems of the waterbodies under consideration on the basis of the data on quantitative characteristics and species
diversity of chironomidae.
This article analyses the endogenous level of antioxidants in the plants growing on the Curonian spit. The authors distinguished two groups of plants with the highest content of anthocyans and the water-soluble antioxidants in plant tissues and determined a positive correlation dependency between the anthocyan content and the level of carotenoids and a negative correlation dependency between the anthocyans and АОА content in the leaves of plants under consideration regardless of environmental conditions.
