The Dunkleosteidae Stensiö family includes large predatory Paleozoic armour fishes. Their remains are rare in the Devonian deposits of the European part of Russia (Central Devonian field). The finds of both Eastmanosteus Obruchev and Dunkleosteus Lehman genus representatives and indefinte dunkleosteids were detected in the area. currently there is a collection of some dunkleosteid remains at the Earth Sciences Museum of Moscow State University. The materials were collected in two localities in 2007-2008 years by the author. Plates of the head and trunk shields, preliminarily determined as Eastmanosteus aff. E. pustulosus (Eastman), were found in the sandy clay deposits of the Ardatovka Horizon (Givetian, Middle Devonian) in the Pavlovsk Quarry, Voronezh Region. An incomplete anterior ventro-lateral plate of Dunkleosteidae gen. et sp. indet., similar to the same plates of the Dunkleosteus-species, was discovered in the sandy deposits of the Zadonsk Horizon (Lower Famennian, Upper Devonian) in the Lime Factory Quarry not far from Livny Town, Orel Region. The brief description of the new findings supplementing the data on the Middle-Late Devonian dunkleosteids of the Central Devonian field is given.

Abstract The article presents new data on the distribution and acclimatization of an alien species of the American coniferous bug (Leptoglossus occidentalis Heidemann, 1910) from the European part of Russia. This bug was discovered in the autumn of 2019 on the territory of the city of Voronezh in the Arboretum of the Voronezh State University of Forestry and Technologies. Currently, L. occidentalis spreads on the territory of Russia only in an urban environment, where it finds optimal environmental conditions (suitable temperature, humidity and shelter for winter locations). Surveys of a number of park and forest park zones, squares and separately growing coniferous trees conducted in 2019-2020 in Voronezh did not reveal the presence of this species. At the moment, in the conditions of the Voronezh region, the center of the spread of this bug is located only in the Arboretum of the Voronezh State University of Forestry and Technologies. In 2020, an increase in the number of the identified group of L. occidentalis was recorded. Further spread of the bug is predicted on the territory of Voronezh. At the moment, no danger to conifers in the European part of Russia from L. occidentalis has been identified and is not yet expected, but constant monitoring of the detected group is required.

The article discusses the use of live plants as the botanical exposition component supplement of the “Natural areas” (hall № 17 “Natural zonality and its components” and № 20 “Desert, subtropical, tropical countries, high-altitude zone”) and “Physico-georaphic regions” (hall № 24 “Continents and parts of the world”) departments in order to visualize information presented in the Earth Science Museum. Demonstration of plants originating from different regions of the world representing different life forms and being structural components of various plant communities allows to visually characterizing thematic aspects of an exposition. That in turn reveal such principles of systematic nature organization as ecobiomorphic and phytocenotic.

The new exhibition is located in Hall 5 «Geotectonics» in the Earth Science Museum at Moscow State University and devoted to an urgent problem of volcanic manifestations in areas of hot spots. Among the large number of active volcanoes on our planet, a significant place is occupied by volcanoes of hot spots and mantle plumes, which are characterized by the eruption of a huge amount of pyroclastic material (Hawaii, Yellowstone) and often form large igneous provinces (Eastern Siberia, Kerguelen, Deccan, Iceland). The exhibition presents geological samples from the funds and collections of the museum staff. All samples are characteristic of hot spot volcanoes and mantle plumes from different regions of the world.
