Algae tests are widely used due to the availability of cultivation conditions and high reproducibility. Freshwater and marine algae are used to estimate the toxicity of drinking, natural and wastewater, water extracts from soils, sewage sludge and production and consumption waste. The presence of dissolved organic matter in the samples, stimulating the growth of algae and the intensity of chlorophyll fluorescence, can significantly affect the result of algae tests, and therefore on the decision on the presence or absence of a toxic effect. When choosing algae as a test culture to determine toxic effects, it is necessary to take into account the possibility of hyperstimulating the number of cells with dissolved organic matter.

Spermophilus suslicus is a threatened species listed in Red Data Books at all levels (from regional Red Data
Books to the IUCN Red List of Threatened Species), and it currently requires special conservation activity.
Over the past 30–50 years, its range has changed from continuous to mosaic, and its population has declined
everywhere. In 2015, in Russia experimental ...

Snow drought has become a research hotspot due to its widespread impacts on ecosystems and water resources, yet its effects on vegetation phenology remain relatively understudied. Focusing on the Mongolian Plateau, this study used the Snow Water Equivalent Index and the start of growing season (SOS) to assess the associations between snow drought and vegetation ...

This work presents a new analytical solution of the shallow water theory for cylindrical propagation of long tsunami-like waves in the basin of variable depth. Considered model cases are related to tsunami wave propagation from an asteroid fallen into the sea, or from underwater volcanic eruptions. The corresponding bottom geometries represent radially symmetric obstacles such ...

In this letter, bipolar solitary wave interactions in the Schamel equation are revisited numerically. Two simulation settings are considered: repeated collisions in a periodic domain, and the interaction of a positive solitary wave with a train of negative polarity solitary waves of equal amplitude. In the first case, when the amplitudes are comparable, the larger ...

В обзоре интеллектуальное наследие В.И. Вернадского (1863-1945) рассматривается в контексте зарубежных инвайронментальных исследований (преимущественно на материале англоязычных публикаций двух последних десятилетий). Реконструируются ключевые идейные истоки мировоззрения Вернадского: влияние В.В. Докучаева, русского космизма и концепции ноосферы П. Тейяра де Шардена. Анализируются понятия научной системы Вернадского - «живое вещество», «биосфера» и «ноосфера»; прослеживается их рецепция в современных ...

Rangeland degradation is a global environmental challenge; however, intense debate persists between equilibrium (focused on the negative effects of grazing intensity) and non-equilibrium (emphasizing livestock mobility for adapting to climate variability) theories in rangeland ecology. In recent years, an integrative theory advocating the “coexistence of equilibrium and non-equilibrium” has emerged to reconcile this debate. However, ...

Migration for higher education is one of the largest and most intense migration flows in most developed countries, and Russia is no exception. The direction of educational migration flows is determined by many factors. Among these, traditionally significant determinants of the basic gravity model include the population size of the centers participating in migration exchange ...

The carbon balance of an ecosystem is the difference between Gross Primary Productivity (GPP) and Ecosystem Respiration (Reco) as expressed by Net Ecosystem Exchange (NEE). While remote sensing retrievals of GPP have reached maturity, Reco estimation remains underexplored and ultimately cast bias on NEE.
