Effect of the Concentration of Cations (Ca2+, Mg2+, Na+, and K+) in Water on the Level of Oxidative Processes in the Tissues of Bivalves of the Family DreissenidaePleiades Publishing Ltd - Tập 54 - Trang 165-171 - 2023
A. S. Sokolova, O. L. Tselmovich, D. V. Mikryakov
The results of studying the influence of the content of Ca2+, Mg2+, Na+, and K+ cations in water on the level of lipid peroxidation products and antioxidants in the tissues of bivalve mollusks, D. bugensis and D. polymorpha, are presented. Mollusks were caught in four water areas of the Gorky Reservoir, which differ in the concentrations of Ca2+, Mg2+, Na+, and K+ cations. A correlation relationsh...... hiện toàn bộ

The State of Food Resources and Reproductive Success of Tufted and Horned Puffins in the Northern Sea of OkhotskPleiades Publishing Ltd - Tập 33 - Trang 356-365 - 2002
E. Yu. Golubova
Studies on the reproductive biology of seabirds on Talan and Umara islands in 1987–1999 showed that the diet of nestlings and reproductive success of the tufted puffin (Lunda cirrhata) and horned puffin (Fratercula corniculata) considerably varied in different colonies. This was determined by differences in the hydrologic characteristics of water areas and the state of food resources in Taui Bay (...... hiện toàn bộ
Morphophysiological Rearrangements in Fish in Response to Pollution (in the Light of S.S. Shvarts' Theory)Pleiades Publishing Ltd - Tập 31 - Trang 429-438 - 2000
T. I. Moiseenko
The results of a study on morphophysiological variation in fish inhabiting a subarctic lake exposed to chronic industrial pollution are described using an example of cisco, Coregonus lavaretus. It is shown that indices of the heart, liver, kidneys, gills, and fatness in these fish are increased significantly and have retained increased values for the past 20 years. The observed changes are analyze...... hiện toàn bộ
Ecological status of coral communities in the island area of the Nha Trang Bay (Vietnam)Pleiades Publishing Ltd - Tập 46 - Trang 456-462 - 2015
K. S. Tkachenko
The ecological status of coral communities in the island area of the Nha Trang Bay (Central Vietnam) has been evaluated in March to May 2013. The material has been sampled at five stations from depths of 3–6 m using the photoquadrat method. It has been shown that characteristics of these communities markedly change with distance from the Nha Trang City and the sources of eutrophication and sedimen...... hiện toàn bộ
Small mammal communities in forest ecosystems affected by urbanizationPleiades Publishing Ltd - Tập 45 - Trang 490-497 - 2014
N. F. Chernousova, O. V. Tolkach, O. E. Dobrotvorskaya
A set of characters has been used to evaluate transformations in forest phytocenoses and their small mammal communities affected by urbanization, compared to conditionally undisturbed phytocenoses (communities). In park forests of the city of Yekaterinburg, the understory and subordinate shrub and herb-dwarf shrub layers of phytocenosis are transformed to a greater extent. The undergrowth of conif...... hiện toàn bộ
