The structure of the existing system and the problems of functioning of the future specially protected natural territories of the Voronezh region

The Biological Diversity Convention and the National Strategy for the Conservation of Biodiversity in Russia have laid the basis for the implementation of large-scale scientifi c and practical research aimed at fi nding eff ective solutions to this issue. The creation of the SPNA network which includes federal, regional and local signifi cance is one of the promising directions for the conservation, maintenance and reproduction of biodiversity at all levels.

Adventive component of the seed bank of some forest communities of the Volga River islands

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%).

Among the newly discovered species 2 were new for Europe and 3 for Russia.

Methodical Principles of the Procedure of Entering and Deleting Biological Species in the Third Edition of the Red Data Book of the Saratov Region

Basic principles underlying the methodology of the procedure of entering and deleting biological species in regional Red Data Books are shown. With Natrix tessellate as an example, an algorithm is demonstrated to exclude a species from the list of rare and endangered animals needing special protection measures. As a result of our longterm field studies of the N. tessellata populations, a positive trend in the abundance change in its population and in the spectrum of biotopical correspondence and geographical distribution within the Saratov region has been established.

The Structure of Morphological Variability and Vitaliti in the Populations of Tulipa Gesneriana L. in the Lower Volga Region and Adjacent Territories

During four field seasons (2013–2016.) conducted a study of the structure of morphological variability and vitality. 38 populations of Tulipa gesneriana in several areas of the Lower Volga region and adjacent territories. The significant variability in the vitality structure of the populations as on the interpopulation level, and year. It is revealed that years of observation in General, most populations of the species were quite pronounced tendency for a gradual reduction of vitality. from 2013 to 2015 and significantly improve the plants in them in 2016.

Ecological Problems of the Saratov Region in Year Environment and the Year of Specially Protected of Natural Territories

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

The Additional Data about Spring Beetles Fauna (Insecta: Coleoptera) of the Natural Monument «Rasskazan’ Lake» (Saratov Province)

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.
