Adventive Flora

Biological pollution of natural phytocenoses by adventive plant species poses is a serious threat to endemic species and species with narrower ecological amplitude in ecosystems around the world. This study presents the results of a study of the composition and distribution of adventive plant species in natural, semi-natural and anthropogenic transformed phytocenoses of Volyn’ Polissya, Ukraine. To clarify the effect of drainage melioration on non-native flora species distribution, a botanical study was carried out during the 2003–2019 vegetation seasons on the territory of four drainage systems. The adventive flora of this unique region of Europe was studied in detail for the first time. In total, 279 non-native plant species were found. They belong to 110 genera and 32 families. The results of studying the systematic, bioecological, range-distributional and phytogenetic structure of adventive species found within agricultural lands and adjacent territories are presented. It was found that 161 species are associated with agricultural production. Of these, 90 species were found directly within the agricultural land, another 71 species were found growing in the adjacent territories. It was found that a significant increase in the number of adventive species on the territory of Volyn’ Polissya is associated with drainage melioration carried out in the 1960–1990s, significant changes in the structure and forms of agro-industrial production, and climatic changes in recent decades. The expansion of agricultural land in this area over the past 50–60 years has led to an increase in the number of adventive species by more than 60%. On the territory of drainage systems used for agricultural activities, more than 40% of the total species composition of the adventive flora of Volyn’ Polissya is represented. The majority of these species originate from arid and sub arid regions of the planet. The transformer plants, Solidago canadensis L. and Phalacroloma annuum (L.) Dumort pose a potential threat to phytocenoses of the described region, as well as the whole of Europe. Of particular interest are the species that in the future may pose a serious threat to natural phyto-diversity and have negative practical consequences for the structure of agricultural landscapes. These are Ambrosia artemisiifolia L. and Heracleum sosnowskyi Manden. In general, modern agro ecosystems are characterized by instability and low ability to resist non-native species. The strongly weedy character of cultivated fields and the presence of abandoned uncultivated lands have caused the rapid spread of adventive vegetation. In order to further optimize the structure of agrolandscapes, it is advisable to monitor and regulate not only expansionary invasive species, which is especially important for preventing biological pollution, but also species whose status has not yet been determined.

This study aims to examine and compare the 6th grade students’ perception of environmental issues through different techniques.  For this purpose, we have tried to establish the students' perception of environmental issues by studying the pictures they drew and the written texts they wrote.   In this study, where we have conducted with 62 students in two different secondary schools in Duzce central during the 1st semester of the 2014-2015 academic year, we have employed a phenomenological pattern.  The obtained data has been analyzed using content analysis method.  As a result of the study, the themes of air pollution, water pollution, soil pollution, visual pollution, endangerment of species, noise pollution, natural disasters, biological pollution and radioactive pollution in the students’ perception of environmental issues have been identified.  When the themes of environmental problems, obtained through two different techniques, have been compared, it has been established that the number of themes expressed in the written texts were higher than the ones in the pictures.

Party State

In COVID-19's first months, US politicians and media forecast that a contrast between Chinese deception and incapability and Western success against the pandemic might fatally sink internal confidence in China's party-state. They also predicted that it would diminish China externally, as it came to be seen as endangering the world by spreading biological pollution. A "China's Chernobyl" prediction became the latest "China collapse" wish-fulfillment. This speculation rests on two contradictory yet co-existing Yellow Peril tropes: "deceit and incompetence" and "world domination." However, no empirical basis exists for either notion: China prevailed against the pandemic and lacks the capacity for global hegemony. "China's Chernobyl" is most relevant then as a wish that creates a belief, that China should and could collapse. That in turn bolsters the US-led mobilization to counter China as a "strong competitor" and frames China as the common enemy, thereby promoting Western transnational and US internal cohesion.

Monitoring Study

In recent years, Mongolia's river water has been heavily polluted by human activities, mining, industrialization, and other factors, and the river's flow has been declining every year, conducted a pilot study to monitor the study. The water sample contains an average of 0.7 million cells/ml of bacteria, which indicates low bacterial contamination.
