“…Excess pollutants accumulate in coastal water and sediment along with municipal and industrial wastewater discharge, which adds additional stressors to microbial communities ( Sun et al, 2012 ). As a result, polluted areas often present a higher abundance of pollutant-tolerant species and divergent community composition, compared to pristine areas ( Sun et al, 2013 ; Quero et al, 2015 ; Gubelit et al, 2016 ). Consequently, identifying microbial dynamics in response to pollutant input at the species or community level is thought to be useful in evaluating possible impacts of anthropogenic disturbance ( Aguirre et al, 2017 ; Richa et al, 2017 ).…”

Dynamics of Sediment Microbial Functional Capacity and Community Interaction Networks in an Urbanized Coastal Estuary

et al. 2018

Coastal estuaries and bays are exposed to both natural and anthropogenic environmental changes, inflicting intensive stress on the microbial communities inhabiting these areas. However, it remains unclear how microbial community diversity and their eco-functions are affected by anthropogenic disturbances rather than natural environmental changes. Here, we explored sediment microbial functional genes dynamics and community interaction networks in Hangzhou Bay (HZB), one of the most severely polluted bays on China’s eastern coast. The results indicated key microbial functional gene categories, including N, P, S, and aromatic compound metabolism, and stress response, displayed significant spatial dynamics along environmental gradients. Sensitive feedbacks of key functional gene categories to N and P pollutants demonstrated potential impacts of human-induced seawater pollutants to microbial functional capacity. Seawater ammonia and dissolved inorganic nitrogen (DIN) was identified as primary drivers in selecting adaptive populations and varying community composition. Network analysis revealed distinct modules that were stimulated in inner or outer bay. Importantly, the network keystone species, which played a fundamental role in community interactions, were strongly affected by N-pollutants. Our results provide a systematic understanding of the microbial compositional and functional dynamics in an urbanized coastal estuary, and highlighted the impact of human activities on these communities.

“…Polluted areas usually show higher types of pollutant resistance and different community compositions, when compared with pristine areas (Sun et al, 2013;Quero et al, 2015;Gubelit et al, 2016). The presence of potential pathogenicity and pollution indicator bacteria, such as Vibrio, Pseudoalteromonas, Escherichia-Shigella, Psychrobacter, and Pseudomonas, along with strong hydrodynamic conditions of the current migrating westward, makes the ecological risks more serious.…”

In this study, 39 sediment samples were collected from Qilian Island, Iltis Bank, and Yongxing Island in Xuande Atoll in the South China Sea (SCS), and the microbial community structures and distribution were analyzed. The microbial community was influenced by both natural environmental factors and human activities. The abundance of genera Vibrio and Pseudoalteromonas, which are associated with pathogenicity and pollutant degradation, were significantly higher in Qilian Island than in Yongxing Island and Iltis Bank, suggesting possible contamination of Qilian Island area through human activities. Pathogenic or typical pollutants-degrading bacteria were found to be negatively correlated with most of the commonly occurring bacterial populations in marine sediment, and these bacteria were more likely to appear in the sediment of deep water layer. This co-occurrence pattern may be due to bacterial adaptation to environmental changes such as depth and contaminations from human activities, including garbage disposal, farming, and oil spills from ships. The findings of this study could help in understanding the potential influences of human activities on the ecosystem at the microbial level.

“…металлы были ранжированы [23] в порядке: Cu > Pb > Co > Cd > > Zn > Ni > Mn. Несмотря на различия в содержании металлов в воде и донных осадках в прибрежной зоне Финского залива [23,33] у Курортного района и акватории у г. Петергофа, уровни накопления металлов в органах и тканях двустворчатых моллюсков оказались статистически неразличимыми. Исключением был только Pb, трехкратное превышение которого зарегистрировано в жабрах моллюсков из акватории у г. Петергофа по сравнению с моллюсками из прибрежной зоны Финского залива у Курортного района (табл.…”

Assessment of the quality of freshwater ecosystems based on the functional condition of bivalved mollusks

et al. 2019

View full text Add to dashboard Cite

An approach is proposed for ranking the quality of freshwater ecosystems by the state of bivalve mollusks living in them. Cardioactivity indicators and accumulation of metals in the tissues of the mollusks from various waters of the eastern part of the Gulf of Finland and the Rybinsk Reservoir were used to characterize the ecosystems, and an original hyperosmotic test was used to analyze the functional state of the mollusks.
