The intensification of the hunting industry leads to an increase in the number of animals and creates conditions for the spread of invasions, incl. helminthic. The transboundary position of the Western regions of Ukraine contributes to the expansion of the species composition and habitats of helminths, which in the current climate change can complicate the epizootic situation of dangerous invasions. On the basis of the literature and the results of our own research, potential risks to the hunting economy for the emergence of new helminthiasis caused by the species-species have been identified. In the work the influence on the helminth fauna of ungulates, kept under conditions in the aviary, modifying and regulating environmental factors, is analyzed. The modern changes in the phenology and ontogeny of pathogens of mass infestations, first of all in geo-helminths, have been investigated. For the causative agent of dictiocaulosis, prolongation of the seasonality of invasion by larvae has been established. It is shown that the decrease in the extent and intensity of invasion of individual trematodes correlates with the dynamics of their intermediate hosts. The data on the effectiveness of remediation with aqueous solutions of polyhexamethyleneguanidine chloride, landing sites were obtained by decontamination of soil in wildlife clusters, in order to minimize their infestation by nematode larvae. The proposed remedy is an organic compound, does not scare away animals, but by contacting organic and inorganic constituents of the soil and lose their potential toxicity. Efficiency of destruction of larvae of Strongylid and Strongylate in the sample ranged from 78 % to 87 %, and in the surface (up to 5 cm) soil layers – 96–100 %. Research findings should be reflected in planned antiparasitic measures.

In many public policy areas, such as climate change, news media reports about scientific research play an important role. In presenting their research, scientists are providing guidance to the public regarding public policy choices. How do people decide which scientists and scientific claims to believe? This is a question we address by drawing on the psychology of persuasion. We propose the hypothesis that people are more likely to believe local scientists than national or international scientists. We test this hypothesis with an experiment embedded in a national Internet survey. Our experiment yielded null findings, showing that people do not discount or ignore research findings on climate change if they come from Europe instead of Washington-based scientists or a leading university in a respondent’s home state. This reinforces evidence that climate change beliefs are relatively stable, based on party affiliation, and not malleable based on the source of the scientific report.

Ebolaviruses and marburgviruses are filoviruses that are known to cause severe hemorrhagic fever in humans and nonhuman primates (NHPs). While some bat species are suspected to be natural reservoirs of these filoviruses, wild NHPs often act as intermediate hosts for viral transmission to humans. Using an enzyme-linked immunosorbent assay, we screened two NHP species, wild baboons and vervet monkeys captured in Zambia, for their serum IgG antibodies specific to the envelope glycoproteins of filoviruses. From 243 samples tested, 39 NHPs (16%) were found to be seropositive either for ebolaviruses or marburgviruses with endpoint antibody titers ranging from 100 to 25,600. Interestingly, antibodies reactive to Reston virus, which is found only in Asia, were detected in both NHP species. There was a significant difference in the seropositivity for the marburgvirus antigen between the two NHP species, with baboons having a higher positive rate. These results suggest that wild NHPs in Zambia might be nonlethally exposed to these filoviruses, and this emphasizes the need for continuous monitoring of filovirus infection in wild animals to better understand the ecology of filoviruses and to assess potential risks of outbreaks in humans in previously nonendemic countries.

Describes the tension between global environmental protection and a local focus on the most disadvantaged communities. The chapter analyzes the development of California’s landmark climate change legislation: Assembly Bill (AB) 32. It illustrates the contentious nature of defining climate change and how the entanglements of diverse knowledges and worldviews shape contemporary climate governance and decision-making processes.

This chapter examines both concept of global hazard and disaster and its management in the lights of its vulnerability. It categorized the different types of hazards and disasters and their components. From the research findings, it is observed that hazards and disaster are two sides of a coin. They occur at the interface between human systems and natural events in our physical environments. This chapter highlights that the major environmental changes driving hazards and vulnerability to disasters are climate change, land-use changes, and degradation of natural resources. After presenting a typology of disasters and their magnitude globally, management of disaster has transited from just being a “response and relief”-centric approach to a mitigation and preparedness approach.

This Special Issue brings together recent research findings related to urban resilience, in particular taking into account climate change impacts and hydrological hazards. Taking advantage of the work done in the H2020 RESCCUE project, 12 different papers dealing with several issues related to the resilience of urban areas have been published. Due to the complexity of cities, urban resilience management is one of the key challenges that our societies have to deal with in the near future. In addition, urban resilience is a transversal and multi-sectorial issue, affecting different urban services, several hazards, and all the steps of the risk management cycle. This is precisely why the papers contained in this Special Issue focus on varied subjects, such as impact assessments, urban resilience assessments, adaptation strategies, flood risk and urban services, always focusing on at least two of these topics.
