Abstract Background Myxococcota, characterized by their distinct social lifestyles, are widely distributed micro-predators in global sediments. They can feed on a wide range of bacterial, archaeal, and fungal prey. Myxococcota capable producing diverse secondary metabolites, playing key roles microbial food webs, regulating the community structures different ecosystems. However, rarely pure cultured due to challenging stringent culturing conditions. Their natural distribution, niche differentiation, predator–prey relationships specific habitat poorly understood. Results In this study, we conducted comprehensive analysis 16S rRNA gene sequence data from public databases our collection. We compared abundance, diversity, distribution patterns various habitats, with focus mangroves. found that accounted for 1.45% total prokaryotes sediments based abundance genes. abundant mangrove tend be more generalistic mangroves than other habitats breadth. Besides, deterministic processes (variable selection) influenced assembly communities significantly stochastic processes. Further, determined environmental factors explained greater amount variation geographical variables (latitude sediment depth). end, through co-occurrence networks, emerges as component functions connector community. Conclusions Our study enhances comprehension Myxococcota's biogeography, patterns, driving factors, relationships, well highlights unique ecological importance

Mangroves stand out as one of the most diverse and biologically significant natural systems in world. Playing critical roles maintaining health productivity coastal ecosystems, mangroves provide a range services functions, including habitat for local fauna flora, food other goods, carbon sequestration, protection from disasters such storm surges erosion. It is also evident that face several threats, which have already led to gradual depletion mangrove areas worldwide. Based on analysis current related historical literature data, this review summarises functions threats challenges associated with management practices. Our findings suggest development, expanded aquaculture, deforestation, climate change, implications eutrophication, diseases, pollution are major factors posing sustainability. We highlight various challenges, land use conflict, lack stringent regulatory actions, inadequate policy government frameworks, community awareness, underlie ineffective management. The implementation inclusive coordinated approaches involving stakeholders different backgrounds interests, governmental non-governmental organisations, academia essential restoration sustainable by adapting mitigation strategies.

Abstract Background Mangrove ecosystems are vulnerable due to the exotic Spartina alterniflora ( S. ) invasion in China. However, little is known about mangrove sediment microbial community assembly processes and interactions under invasion. Here, we investigated co-occurrence networks of archaeal bacterial communities along coastlines Fujian province, southeast Results Assembly overall was driven predominantly by stochastic processes, relative role stochasticity stronger for bacteria than archaea. Co-occurrence network analyses showed that structure more complex The keystone taxa often had low abundances (conditionally rare taxa), suggesting abundance may significantly contribute stability. Moreover, increased drift process (part processes), improved complexity stability, but decreased stability bacteria. This could be attributed influenced diversity dispersal ability, as well soil environmental conditions. Conclusions study fills a gap patterns both archaea ecosystem Thereby provides new insights plant on biogeographic distribution patterns.

Methanogens are crucial to global methane budget and carbon cycling. from the phylum Euryarchaeota currently classified into one class seven orders, including two novel methanogen taxa, Methanofastidiosa Methanomassiliicoccales. The relative importance of methanogens production in natural environment is poorly understood.Here, we used a combined metagenomic metatranscriptomic approach investigate metabolic activity mangrove sediments Futian Nature Reserve, Shenzhen. We obtained 13 metagenome-assembled genomes (MAGs) representing (Methanofastidiosa) five orders (Methanomassiliicoccales, Methanomicrobiales, Methanobacteriales, Methanocellales, Methanosarcinales) methanogens, methanogens. Comprehensive annotation indicated presence an H2-dependent methylotrophic methanogenesis pathway Based on functional gene analysis, hydrogenotrophic dominant pathways sediments. MAG mapping revealed that Methanomicrobiales were most abundant Methanomassiliicoccales active analyzed sediment profile, suggesting their important roles production.Partial or near-complete Methanomassiliicoccales, environments recovered here for first time. presented findings highlight ecological complement knowledge how produced ecosystem.
