Heterothermy in a Small Passerine: Eastern Yellow Robins Use Nocturnal Torpor in Winter

Torpor is a controlled reduction of metabolism and body temperature, and its appropriate use allows small birds to adapt to and survive challenging conditions. However, despite its great energy conservation potential, torpor use by passerine birds is understudied although they are small and comprise over half of extant bird species. Here, we first determined whether a free-living, small ∼20 g Australian passerine, the eastern yellow robin (Eopsaltria australis), expresses torpor by measuring skin temperature (Ts) as a proxy for body temperature. Second, we tested if skin temperature fluctuated in relation to ambient temperature (Ta). We found that the Ts of eastern yellow robins fluctuated during winter by 9.1 ± 3.9°C on average (average minimum Ts 30.1 ± 2.3°C), providing the first evidence of torpor expression in this species. Daily minimum Ts decreased with Ta, reducing the estimated metabolic rate by as much as 32%. We hope that our results will encourage further studies to expand our knowledge on the use of torpor in wild passerines. The implications of such studies are important because species with highly flexible energy requirements may have an advantage over strict homeotherms during the current increasing frequency of extreme and unpredictable weather events, driven by changing climate.

REGIONAL FEATURES OF INNOVATIVE DEVELOPMENT AND DIFFERENTIATION OF DIRECTIONS OF INNOVATION POLICY OF RUSSIA

In our manuscript we have made an attempt to study specific sides of Russian Federation’s innovative development, analyze its impact in economy growth and provide main ways of innovative policy realization in different types of regions. The method is based on partial abstraction from the unique properties of each region, thereby uniting them into homogeneous groups using k-means method. Further analysis of the determination of the main factor at the level of country was carried out using decision trees functions with the subsequent collection of OOB errors. Group analysis was carried out using regression analysis. As a result, the authors obtained five types of regions (with a high, above average, average, below average, low level of innovative development), provided an individual characteristic for each group regarding the innovation development and identified prerogative innovative factors that can be considered by the state as a criterion for differentiating state policy and regulation of the development of innovation policy.

We are All in This Together: The Comparison of Coronavirus' Experiences in Croatia and Other European Countries

Different countries were successful in different ways in their attempts to contain the spread of the coronavirus, which compromised the health of many people. Stress levels rose and the restrictive measures impacted the citizens' trust in institutions. An important resource for managing crises is a country’s economic growth. Given that the gross domestic product (GDP) per capita is one indicator of economic growth, the goal of this study is to investigate the differences in perceived stress and trust in institutions between European countries categorized into below-average, average and above-average GDP per capita levels during the coronavirus pandemic. The analyses of N = 84,080 participants from 29 countries gathered via an online survey showed that citizens of higher-level GDP per capita countries experienced less stress and had more trust in institutions. Compared to the average level, Croatian citizens experienced somewhat higher stress and had somewhat higher trust in the government’s measures. These results imply that economic growth is one of the country-level factors associated with the quality of managing the coronavirus pandemic.

Assessment of the geo-ecological potential of the landscape districts (on the example of Sumy region, Ukraine)

The article is devoted to the study of the life potential support of the population, which reflects living conditions of the population in specific geosystems (on the example of the Sumy region, Ukraine). The main purpose of the article is to assess the geo-ecological potential of the regional landscape structures, namely the landscape districts of the Sumy region. The article highlights the theoretical and methodological foundations of the geoecological potential research, substantiates the theoretical aspects of the of “geo-ecological potential” concept, describes in detail the methodology of assessing geo-ecological potential, which is evaluated on the basis of natural geosystem potential, geosystem sustainability potential and technogenic geosystem load. The assessment of the natural potential of the Sumy region landscape districts (based on the humidity coefficient, the sum of active temperatures above 10°C, hydrothermal potential of phytomass productivity, annual precipitation, adverse natural processes such as landslides, flooding, rising groundwater levels, erosion, dry winds, hail, fogs) is conducted and the levels (low, below average, average and high) of the natural potential are defined. Three districts of the environmental sustainability of the regional landscape districts are established on the basis of component-by-component assessment of the meteorological potential of the atmosphere, surface water and soil sustainability potential, as well as biotic potential: below average, average and above average. The indicators of the population density of the region, coefficient of the territorial production concentration, economic development of lands (agricultural lands, built-up lands and open lands without vegetation), environmental pollution of the region (radiation and chemical air pollution, pollution of natural waters and soils) and the integrated indicator of technogenic load, which allows to establish the following levels of the technogenic load on the landscape districts of the region: below average, average and above average, are analyzed. Particular attention is paid to the assessment of the geo-ecological potential, which allows to establish 5 levels, of which only 3 are presented in Sumy region, based on which areas of geo-ecological potential of the landscape districts are identified: below average, average and above average and a map of the geo-ecological potential areas is created. It is established that the indicator of the geo-ecological potential of the landscape districts of the Sumy region ranges from 0.05 Psel-Vorskla landscape district (below average level) to 1.07 Esman’-Kleven’ landscape district (above average level). It is established that the higher the values of the natural potential and sustainability of the natural environment and the lower the indicators of technogenic load, the higher are the values of the geo-ecological potential.

Creative methods of noospheric learning through art assets: Case study of authentic education

In this article authors discuss the methodology of evaluating noospheric insights in higher education students through art assets. A very important goal of students’ inclusion into the authentic context of ecological education is being achieved. As a result of this study, evaluation criteria were determined, such as imagination, emotionality, originality, abstraction. For the more in-depth development of the evaluation procedure the following methods were used: educational experiment, observation, questionnaires, semantic differential (SD), method of setting the attitude on associative transformation of the object being perceived, creative methods. Authors determined the levels of student’s noospheric insights formation (high, above average, average, low) for the following evaluation of correlation between the categories of singular, special and common in students’ aesthetical insights. The results, including content and structural, functional components, are described in this article, allowing to connect the process of noosperic insights mastering by students with the authentic context of education.
