The paper presents the results of studying the adventive component of the seed bank of the Oak Mane Island of the Volga River Valley in the vicinity of the city of Saratov. Seeds of 12 species of adventitious plants were registered in the seed bank of the studied forest communities. All identifi ed seeds belong to plant species belonging to one department of Magnoliophyta, 8 families and 12 genera. The Asteraceae family plays a leading role in the taxonomic spectrum of adventitious seed bank species (42%).

Представлены материалы по изучению биологического разнообразия беспозвоночных и позвоночных животных природных комплексов Саратовской области за длительный период изучения (с середины ХХ в.) и сделан обобщенный анализ современного состояния биологического разнообразия региона. В различных экосистемах и биотопах области зарегистрировано 12512 видов беспозвоночных, среди которых наиболее многочисленной группой являются Насекомые (около 12000 видов), Паукообразные (свыше 300), Ракообразные (около 100).

Presents the distribution of 3489 species of Lepidoptera from 83 families on the basic administrative units of the region. To the base list of E. Eversmann added 2209 species, 35 species were removed from the list as incorrectly identified previously, reliably disappeared in the region or accidentally introduced. Among the newly discovered species 2 were new for Europe and 3 for Russia.

The ecological problems of the Saratov region in the Year of Ecology and Protected Areas are discussed: the degradation and destruction of natural complexes, the reduction of species biological diversity and its causes, the need to expand the network of regional SPNA, reduce atmospheric pollution, hydrosphere and lithosphere (limiting emissions of harmful substances and reagents, non-waste technologies, introduction of alternative energy, modern technologies for waste processing and wastewater treatment), soil fertility conditions, growth new technogenic pollutants (ele

In the article results of use of Malaise trap for the study of the beetles local fauna (Insecta: Coleoptera) in the territory of National Park «Khvalynsky» is given. Compiled a list of 95 species from 32 families Coleoptera. Antherophagus pallens (Linnaeus, 1758) and Saperda octopunctata (Scopoli, 1772) are recorded for Saratov region in first time.

In the article the results of short-term investigations of water-land biotopes of the natural monument «Rasskazan’ Lake» (Balashov district of the Saratov Province) is presents. Compiled a list of 67 species from 9 families Coleoptera.

The collections were realized out in June – September 2018 using the original light trap within the city of Krasnodar. The article contains lists of 74 species (1252 specimens) of Coleopteran from 15 families: Carabidae – 13 species, Hydrophilidae – 12, Dytiscidae – 6, Elateridae – 6, Curculionidae – 4, Coccinellidae – 3, Heteroceridae – 2, Tenebrionidae – 2, Chrysomelidae – 2, Spercheidae, Scirtidae, Cantharidae, Bostrichidae, Anthicidae and Cerambycidae – in 1 species.

The present work is a continuation of the inventory of the coleopterofauna of the water-terrestrial ecotones of the nature monument «Rasskazan’ Lake» Balashov district of Saratov province, which began in 2017. The study concerned the spring fauna of the period of occurrence of the Khoper river in low water after floods and the beginning of the stagnation of the lake water level.

The article describes the new experience of the long-term use of the Malaise trap (tent trap) for the season 2018–2019 on the territory of the National Park «Khvalynsky» (Saratov province). During this period, 44 species of beetles belonging to 19 families were recorded 6 species: Leiodes obesa (Schmidt, 1841), Philonthus concinnus (Gravenhorst, 1802), Mordellistena humeralis (Linnaeus, 1758), M. intersecta Emery, 1876, M. purpureonigrans Ermisch, 1963 and Scraptia fuscula P. W. J. Muller, 1821 were recorded in the fauna of Saratov oblast for the first time.
