Paper presents analysis of the literature data on mechanisms that provide thermoresistance of algae. Issues of biosynthesis and role of the heat shock proteins, structural changes of membrane lipids and activation of the antioxidant system in the resistance of the algal cells to the influence of elevated temperature are discussed.

biomonitoring
The content of heavy metals was studied in the soft tissues of Bivalvia and Gastropoda occurring in water bodies and watercourses of Gomel and adjacent territories. Valid relationship was established between their content in soft tissues and in abiotic components. It has been found that this relationship depends on the peculiarities of a species, and also on the chemical nature of the metal. It has been shown that mainly the shells of Gastropoda and Bivalvia, as well as the soft tissues of Limnaea stagnalis L., Viviparus viviparus L., and Unio pictorum L., should be used in monitoring the total contamination of aquatic ecosystems by heavy metals.

oxidative stress
molecular biomarkers.
Toxic effects of Al3+ on the liver cells and neural tissue of pumpkinseed Lepomis gibbosus were studied on the basis of the oxidative stress parameters and state of the cytoskeleton. Chronic impact of aluminum ions in concentration 0.01 mg/cm3 induced oxidative stress and peculiar response of the brain astrocytes. Astrogliosis was shown to be closely associated with development of oxidative stress in the neural tissue. Parameters of oxidative stress and astroglia's response to the toxic effect of Al3+ ions serve as markers of the organism's ability to adapt to worse environmental conditions.

The resistance of invasive species of Gammaridae of littoral zones of Kiev and Kaniv reservoirs Chaetogammarus ischnus, Pontogammarus robustoides, Dikerogammarus villosus and D. haemobaphes to impact of the heavy metal ions has been investigated. Considered species were shown to be highly sensitive, similar to the standard test objects Daphnia magna and Ceriodaphnia affinis; the most sensitive were D. haemobaphes and D. villosus. The toxicity of heavy metals to the considered species of Gammaridae decreased in a sequence Cd2+ > Cr6+ > Zn2+.

In June, 2010 ectoparasite Argulus coregoni was found in the middle section of the Kazanka River, left tributary of the Kuybyshev Water Reservoir (Republic Tatarstan, Russia). Paper deals with issues of the geographic distribution of the species, paths of its penetration and conditions, enabling occurrence of the parasite in the river.

hydrodynamic and hydrophysical characteristics of the water
the Dniester Power Complex.
Hydrological factors responsible for the functioning of the ecosystems of the reservoirs of the Dniester Power Complex are discussed in the paper. The external water exchange, intra-water body dynamics, and hydrophysical characteristics of the water were assessed. The mechanisms of the influence of the main factors on some chemical and biological processes occurring in the ecosystems of these water bodies were revealed.
