Genus Adialytus is represented in Europe by four species, only two of which are recorded in the fauna of Ukraine: Adialytus ambiguus (Haliday, 1834) and Adialytus salicaphis (Fitch, 1855). Data on the distribution of these species, their trophic specialization, and habitat associations are provided on the basis of material from the collection of I. I. Schmalhausen Institute of Zoology of the National Academy of Sciences of Ukraine (SIZK) and previous publications. A. ambiguus is a broad oligophagous, however, parasitizing mostly species of the genus Sipha on Poaceae. In Ukraine, A. ambiguus is found in the Forest-Steppe zone (Kyiv, Cherkasy, Kirovohrad, Poltava regions), in the Zone of broad-leaved forests of Ukraine (Ternopil region). Adialytus salicaphis is registered for now only in the Zone of mixed forests of Ukraine (Kyiv region). This species is a narrow oligophagous and develops on aphids of the genus Chaitophorus on Salix and Populus. Its potential areal might include also Forest-Steppe zone (more probably on the Left Bank of Dnieper River) and plains of big rivers in the Steppe zone of Ukraine. The potential role of these species as biocontrol agents is discussed: A. ambiguus could be recommended for consideration as a new candidate for biocontrol of Sipha spp. and probably Rhopalosiphum spp, on cereal crops in Ukraine, while A. salicaphis is not a species of practical importance in the country now. We consider quite probable finding in Ukraine another well-distributed European species A. thelaxis (Starý, 1961), which is a parasitoid of aphids of the genus Thelaxes on oaks.

A new cultivar of smooth bromegrass (Bromopsis inermis Leyss) Flagman was developed by methods of mass selection and polycross. Breeding and wild forms of various ecological and geographical origins are used as an initial material. The authors of the cultivar: Kazarinova I.N., Polyudina R.I., Straub A.A., Gomasco S.K. Studies were conducted on the Central experimental base of the Siberian research Institute of fodder crops of the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences, located in the forest-steppe zone of Western Siberia (Novosibirsk region, Novosibirsk district, Krasnoobsk). The cultivar is mid-ripening: the period from the beginning of spring aftergrowing to mowing ripeness is 63-75 days and to full maturing of seeds is 95-111 days. The yield of dry matter is 8.3 t/ha, which exceeds the standard by 8%, seed yield - 0.62 t/ha, higher than the standard by 28%. The dry matter yield of the cultivar Flagman for the fourth year of use exceeded the standard by 23% and reached to 11.4 t/ha. The 1000 seeds weight is 3.0-3.4 g. The plant height is 90-140 cm. Tilling capacity is up to 40 stems per tuft. Foliage varies from 32 to 50% depending on the age of the grass and environment conditions. The resistance of the cultivar to brown rust and helminthosporiosis is higher than of the standard. The copyright certificate No. 71916 and patent No. 9653 were received.

The forest site capacity using was quantitatively assessed for the stands of the main forest-forming species of Ukraine, Scots pine and common oak, taking into account natural zones and forest types. The tables of productivity of modal and highly productive pine and oak stands have been developed. It has been found that the stands use an average of 50–75 % of the forest site capacity of lands. The average weighted value of the capacity used by pine forests was 68–76 % in the Polissya zone, 70–78 % and 68–73 % in the Right-bank and Left-bank Forest-Steppe zones respectively, and 54–78 % in the Steppe zone. For oak stands, the value was 71–75 % and 63–71 % for the Right-bank and Left-bank Forest-Steppe zones respectively and 65–75 % for the Steppe zone. The basis for increasing the productivity of forests was confirmed to be the differentiation of forest management systems and individual forestry activities on a zonal and typological basis.

Abstract We evaluated the stability of perennial legume and cereal grass species in artificial plant communities on permanent anti-erosion watercourses in the agroecosystems of the Belgorod region with active development of linear soil erosion. In the conditions of steppe and forest-steppe zones of the Belgorod region on permanently grassed watercourses in 2017-2019. varieties of perennial leguminous and cereal grasses: ‘Krasnoyaruzhskaya 1’ and ‘Krasnoyaruzhskaya 2’ (Medicago varia), ‘Kazatsky’ (Trifolium pratense), ‘Olshanka’ and ‘Ivica’ (Festuca arundinacea), ‘Streletsky’ and ‘Stepnyak’ (Lolium perenne)) obtained using local genetic material were studied. All varieties showed their resistance in agro-ecosystems with active development of linear erosion in the forest-steppe and steppe zones. Projective cover on watercourses in the steppe zone in all variants of experience was on average 83,4 %, in the forest-steppe zone - 86,3 %. In the third year of the tests on permanently irrigated watercourses in the steppe zone, the share of cereal and legume grass species was quite high and varied from 88 % in the variant M. varia + Onobrychis arenaria to 92 % in the variants M. varia + Bromopsis inermis and O. arenaria. In the forest-steppe zone, the share of cereal and legume grass species varied from 86 % in the variant L. perenne to 94 % in the variant L. perenne + B. inermis.

Satyr fauna of the Southern trans-Urals is represented by 24 species, 2 of which - P. afra and E. medusa - are included in the Red Book of the Kurgan region as species of vanishing number and range. In terms of the wintering phases of satyrs of the Kurgan region, they are possible to be divided into 2 ecological groups: wintering caterpillars (19 species) and wintering pupae (2 species). The hibernating phases of C. hero , P. afra and C. persephone haven’t been identified. Among satyrs divided by the wideness of trophic specialization of caterpillars there exist broad oligophages and broad polyphages. According to the flight terms of imago satyrs of the Southern trans-Urals, they can be divided into 3 phenological groups: early-summer (6 species), summer (15 species) and late-summer (1 species). Satyr fauna in the region generally can be called forest-steppe. According to the peculiarities of the passage of the main parts of the areas, the satyrs can be divided into 3 groups. The first group unites 4 species that are widespread in the northern and southern forest-steppe, the herbage-grass-turf-grass steppe. The second group includes 16 species that occur only in the forest-steppe zone. The third group consists of 4 species, whose most favorable habitats are located in the herbage-turf-grass steppe. According to the landscape-biotope confinement, regional satyrs can be divided into 4 ecological groups: inhabitants of pine-small-leaf forests, inhabitants of the small forest - campestral landscape, inhabitants of steppes and steppe areas, eurybionts. The fauna of glades of pine-small-leaf forests is mostly rich in species. The generality of the species composition of the satyrs of the small forest - campestral and steppe landscapes reaches 53%. First of all, this is due to the quick spread of cereals in these landscapes, which are fodder plants for caterpillars of most species of this family.

The feckless response of the world community to the mounting threat of climate change has led to a growing interest in climate geoengineering research. In early 2015, the us National Academy of Sciences released two major reports on the topic. While it is notable that both reports recommended some form of public participation to inform research, this article argues that the vagueness of these recommendations could mean that their implementation might not comport with optimal approaches for public deliberation. We outline some options for public deliberation on climate geoengineering and important design considerations.

The search for causes of Reye syndrome has resulted in colorful, if not controversial, incrimination of numerous factors including influenza, varicella, environmental toxins, aflotoxin, inherited metabolic defects, and various medications. Attempts to associate salicylates with Reye syndrome date from the 1960s1-3; most of these reports lacked sufficient design, conduct, or controls to implicate or exclude aspirin as a risk factor. Since 1980, several epidemiologic studies4-6 renewed concern and controversy regarding the role of aspirin in Reye syndrome. As a result, a Public Health Service Task Force was formed which culminated in the Centers for Disease Control/National Academy of Sciences pilot study7 which was designed to address the problems and shortcomings identified in the previous efforts to examine the role of aspirin as a causal factor in Reye syndrome.

The psychologist Anne Treisman dedicated her career to the study of attention and perception, a central concern of cognitive science. While still a graduate student, she modified and reformulated the leading theory of auditory attention. Her discoveries and insights into the role of visual attention in the perception of objects, to which she devoted her subsequent decades of research, have had a lasting influence, not only in experimental psychology but also in vision research, neuroscience and artificial intelligence. In a period of rising interest in the brain, her foundational theories inspired thousands of experiments in her own field and others, and the originality and precision of her experimental design confirmed the continued relevance of behavioural research to the scientific enterprise. Treisman's accomplishments were recognized by the National Academy of Sciences in the USA in 1994 and by the American Academy of Arts and Sciences in 1995. In 1996, she became the first psychologist to win the Golden Brain Award. She received the University of Louisville Grawemeyer Award in Psychology in 2009, and was awarded the National Medal of Science by President Barack Obama at a White House ceremony in 2013.

The recommendations of the National Academy of Sciences (NAS) panel are critiqued from a perspective of broad educational policy and legal influence. The report and the accompanying background papers are endorsed with general acceptance of problem identificaion and formulation. However, the report is challenged for recommendations that are too narrowly conceived, raising questions as to viability of implementation. Specific issues addressed include treating disproportionate placement as a symptom versus problem, legal and professional policy barriers to implementing the report's recommendations, and the role of courts in resolving scientific disputes and programatic concerns.
