The Adaptations of Woody Plants after a Thermal Stress in the Khopyor River Region

Authors: Zanina M. A., Zolotukhin A. A.

The living state of woody plants having different levels of thermal damages in the summer of 2010 was studied. It is shown that a number of species had partial drying out and the death of trees unevenly in plantations of different age and localities. In a favourable ecological environment they remained healthy. They are mesophytes and mesohygrophytes which are on the southern border of the areas, mostly explerents. The trees and shrubs of floodplain forests and certain introducents are tolerant of a thermal stress.

Location Features and Abundance of Waterfowl in the Pond Cooler of the Balakovo Nuclear Power Plant in the Winter

Authors: Voronin M. Y., Mosolova E. Y., Tabachishin V. G., Elovenko A. Y.

On the basis of our 2003–2014 field surveys of the pond cooler of BNPP (Saratov region), peculiarities of the spatial distribution and abundance of waterfowl in the winter were revealed. The stay of 6 waterfowl species was noted during this period in different parts of the pond cooler, namely, Podiceps cristatus, Anas platyrhynchos, Aythya ferina, Aythya fuligula, Bucephala clangula, and Mergus mer- ganser. Interannual variations in the population dynamics of some birds (A. platyrhynchos, B. clangula) were significant and caused by the pre-winter weather.

Seasonal dynamics Individual Plot Sizes of Males and Females of the American Mink (Neovison vison Schreber, 1777) in the Saratov Region

Authors: Savonin A. A., Filipechev A. O.

The estimation size of individual plots the American mink on the res- ervoirs in Saratov region in the period from 2000 to 2014. The average plot size of males – 30.6 hectares, females – 27.8 hectares. During the cold period on most waters plot sizes are increased almost two- fold. Found that females go farther from the center of the rivers and streams than males (females – 203.8 m; males – 166.7 m). American mink is more inclined to the rivers with wide floodplain (χ2 = 26.2; p = 0.01). River with a narrow floodplain populated predator with lower density (χ2 = 15.3; p = 0.04).

Trophobiotic Associations between Ants (Hymenoptera, Formicidae) and Aphids (Hemiptera, Aphidomorpha) in South Zauralye

Authors: Novgorodova T. A., Ryabinin A. S.

Trophobiosis with aphids producing honeydew, which is one of the main energetic resources for ants, plays an important role in their life. These are the first data on the trophobiotic as- sociations between ants and aphids in South Zauralye. Investigations were carried out in the most typical biotopes for the region (forest, meadow, steppe and antropogenic biotopes) in 2006–2013. Trophobiotic interactions with aphids are revealed for 17 ant species from two subfamilies: Formicinae (Formica – 7 species, Lasius – 3, Camponotus – 3) and Myrmicinae (Myrmica – 4).
