New Challenges Towards the Ecological Management of Paliastomi Lake Will Significantly Improve the Local Environment With Far-Going Global Consequences

The publication is addressing the problems of pollution from agricultural sources; municipal wastewater and industry in line with the bacterial pollution caused by migratory waterfowl of Paliastomi Lake that is an internationally recognized habitat, wintery and transit area of the birds and an important tourism site. It reviews: the current state of the environment of Paliastomi Lake at the moment of the chemical and microbiological research and mathematical simulation modeling of possible dissemination of polluting chemicals and bacterial pathogens; pollution by nutrient-rich water causing large blooms of algae and aquatic plants that in its turn leaves little oxygen for fish and other aquatic animals, resulting in the eutrophication followed by suffocation of aquatic life. According to the research provided, the publication recommends ongoing monitoring of not only the lake's inflowing waters, but also seasonal sources of bacterial pollution caused by migratory birds. According to monitoring, the integration of constructed wetlands, localized spraying of bacteriophage cocktails, and feeding the birds, who are potential carriers of pathogenic bacteria, with food supplemented with BCs will help limit bacterial contamination, improve the habitat for local and migratory waterfowl, and ensure the biosecurity of the area.

Plant debris are hotbeds for pathogenic bacteria on recreational sandy beaches

On recreational sandy beaches, there are guidelines for the management of bacterial pollution in coastal waters regarding untreated sewage, urban wastewater, and industrial wastewater. However, terrestrial plant debris on coastal beaches can be abundant especially after floods and whilst it has rarely been considered a concern, the bacterial population associated with this type of pollution from the viewpoint of public health has not been adequately assessed. In this study, microbes associated with plant debris drifting onto Kizaki Beach in Japan were monitored for 8 months throughout the rainy season, summer, typhoon season, and winter. Here we show that faecal-indicator bacteria in the plant debris and sand under the debris were significantly higher than the number of faecal bacteria in the sand after a 2015 typhoon. When we focused on specific pathogenic bacteria, Brevundimonas vesicularis and Pseudomonas alcaligenes were commonly detected only in the plant debris and sand under the debris during the survey period. The prompt removal of plant debris would therefore help create safer beaches.

BackgroundThe purpose of the research was to provide the review of the institutional and legal requirements and evaluation of the existing sanitary-biological research of the Lake Paliastomi waters; study the current state of environment, problems of pollution from agricultural sources, municipal wastewater and industry in line with the bacterial pollution caused by migratory waterfowl of the Lake Paliastomi, an internationally recognized habitat, wintery and transit area of the birds and an important tourism site. ResultsHave been prepared the analytical data on: the review of the institutional and legal requirements; evaluation of the existing sanitary-biological research of the following waters in the Lake; definition of dynamics of sanitary-microbial indicators in flowing waters; study of biological characteristics of secreted pathogenic agents and definition of their vulnerability towards bacteriophages; mathematical simulation model on different scenarios of dissemination of chemical pollutants and pathogenic bacteria in the lake Paliastomi. The researchers identified that the pollution by nutrient-rich water causing large blooms of algae and aquatic plants that in its turn leaves little oxygen for fish and other aquatic animals, resulting in the eutrophication followed by suffocation of aquatic life.ConclusionsThe solution of problem requires complex respond: the selected spring sites, regular monitoring of nitrate contents and other basic physico-chemical water parameters; simultaneous, continuous discharge recording; monitoring and maintaining water levels in the wetlands; removing sediment and organic debris build up in wetland pond and etc.Mathematical modeling of dissemination of the pathogenic bacteria in the Lake Paliastomi enables us to permanently monitor not only the inflowing waters of Paliastomi Lake, but seasonal sources of bacterial pollution due to the migratory birds. In line with monitoring, localized prophylactic point sources spraying of Salmonella bacteriophage cocktail (SBC) by agricultural drones will be useful to restrain bacterial contamination.

Coastal and Marine Socio-Ecological Systems: A Systematic Review of the Literature

The socio-ecological systems (SESs) framework provides cross-disciplinary insight into complex environmental problems. Numerous studies have applied the SES framework to coastal and marine environments over the last two decades. We review and analyze 98 of those studies to (i) describe how SES concepts were examined and measured, (ii) describe how the studies included feedbacks and thresholds, and (iii) identify and analyze elements unique to coastal and marine SES frameworks. We find that progress has been made in understanding key SES properties in coastal and marine ecosystems, which include resilience, adaptive capacity, vulnerability, and governance. A variety of methods has been developed and applied to analyze these features qualitatively and quantitatively. We also find that recent studies have incorporated land-based stressors in their analyses of coastal issues related to nutrient runoff, bacterial pollution, and management of anadromous species to represent explicit links in land-to-sea continuums. However, the literature has yet to identify methods and data that can be used to provide causal evidence of non-linearities and thresholds within SES. In addition, our findings suggest that greater alignment and consistency are needed in models with regard to metrics and spatial boundaries between ecological and social systems to take full advantage of the SES framework and improve coastal and marine management.
