Summary: Sulfate reducing prokaryotes, an ecologically important group of microorganisms, were found to harbor prophages and CRISPR arrays that are widely distributed and have specific patterns within cells. A direct proportional relationship was observed between cellular volume and the number of prophages per cell.

Summary: Coastal wetlands, like the Everglades, face increasing stress from global climate change, which can disrupt their soil microbial communities and their ecological processes. The study used next generation sequencing to analyze the effects of long-term saltwater intrusion on microbial populations in freshwater and brackish marshes. The results showed changes in microbial functions, such as increased sulfite reduction in freshwater soils and decreased methylotrophy in brackish soils, highlighting the impact of soil quality changes on microbial communities before and after disturbance.

Summary: Sulfate-reducing bacteria (SRB) in intertidal sediment along China's coastline show distinct spatial distribution patterns, influenced by various natural factors and pollutants from human activities. Anthropogenic factors can directly or indirectly affect the diversity and composition of the SRB community.

Summary: Sulfate-reducing prokaryotes (SRPs) play a crucial role in sulfur, carbon, and metal cycling in the environment. This study developed multiple metabolic models for SRPs based on genomic information, revealing different energy generation mechanisms through electron transfer pathways. The constructed models provide insights into the metabolic behaviors of SRPs and can be applied to other environmental and industrial microbes for predictive purposes.

Summary: Mangroves provide buffer for inland ecosystems against hurricane winds and storm surge, but their ability to withstand harsh cyclone conditions depends on plant resilience traits and geomorphology. Research shows that Hurricane Irma caused canopy damage to 62% of mangroves in southwest Florida, with tall forests being most impacted. While well-drained sites were able to resprout new leaves within a year, poorly-drained inland sites experienced one of the largest mangrove diebacks on record triggered by Irma. The study indicates that storm surge and ponding were the primary causes of mangrove dieback, rather than wind exposure.

Summary: Sulfate-reducing microorganisms (SRM) play a crucial role in global sulfur and carbon cycles, especially in anoxic marine sediments. They consume fermentation products and hydrogen, affecting microbial communities, particularly members of the Marinilabiliales. This study provides new insights into the ecological networks and community assembly in marine sediment microbes, highlighting the importance of SRM activity in ecosystem functions.

Summary: The study found that a certain number of methanogens and associated phyla in the cathodic biofilm are immobilized as sessile biofilm, with a lower abundance of mobility associated genes and significant enrichment of c-di-GMP. Microbial interaction and motility are predicted as two factors affecting the physiological transitions of the cathodic biofilm.

Summary: The microbial communities in the terrestrial hot springs of the Kamchatka Peninsula were found to actively reduce sulfate, with diverse groups of sulfate-reducing prokaryotes operating in different habitats. The presence of sulfate-reducing prokaryotes varied in different hot springs, with different microbial populations dominating in neutral, slightly acidic, and moderately acidic environments. Archaea of the phylum Crenarchaeota were identified as the mediators of sulfate reduction in high-temperature acidic springs.

Summary: In freshwater wetlands, saltwater intrusion disturbances can disrupt the interactions between respiratory, fermentative, and methanogenic microbes, affecting the decomposition of organic matter. The activity of sulfate-reducing bacteria (SRB) increases due to these disturbances, intensifying their competition with syntrophic bacteria and methanogens for electron donors. This study shows that changes in carbon mineralization following saltwater intrusion are not solely driven by competition between SRB and methanogens, but also by other factors such as the shift in the methanogen community.

Summary: The study used static, elevation, and land cover data to estimate the impacts of sea level rise on urban, developed lands, and coastal wetland systems in South Florida. Different sea level rise projections showed potential impacts on coastal land cover and wetland migration, highlighting the need for mitigation strategies in response to future sea level rise.

Summary: This paper reviews the goals and strategies of phosphorus management in the restoration efforts of the Florida Everglades, and synthesizes the successes, failures, and tradeoffs of current management approaches. It also highlights future directions and proposes questions to guide the discussion of restoration priorities and research needs. The overall aim is to provide an in-depth understanding of phosphorus management in this unique social-ecological system and to explore the coevolution of science and policy in supporting large-scale ecosystem restoration.

Summary: This review discusses the importance of sulfate-reducing bacteria (SRB) in producing hydrogen sulfide and their cryopreservation methods. It highlights the factors affecting microbial viability after cryopreservation and recommends storing SRB in glass vials with low salt concentration. Furthermore, it emphasizes the potential impact of SRB in medical, construction, and environmental sectors from a molecular biological and bioengineering perspective.

Summary: The study in Northeast Shark River Slough (NESS) showed higher organic phosphorus content downstream and the highest soil organic matter content and CO2 efflux at midway sites, indicating microbial respiration in NESS is limited by the availability of labile carbon rather than phosphorus.
