Phylosymbiosis was recently formulated to support a hypothesis-driven framework for the characterization of new, cross-system trend in host-associated microbiomes. Defining phylosymbiosis as ‘microbial community relationships that recapitulate phylogeny their host’, we review relevant literature and data last decade, emphasizing frequently used methods regular patterns observed analyses. Quantitative is provided by statistical evaluating higher microbiome variation between host species than within species, topological similarities dendrogram, positive association genetic beta diversity. Significant degrees are prevalent, but not universal, microbiomes plants animals from terrestrial aquatic habitats. Consistent with natural selection shaping phylosymbiosis, transplant experiments demonstrate reduced performance and/or fitness upon host–microbiome mismatches. Hybridization can also disrupt phylosymbiotic cause hybrid pathologies. The pervasiveness carries several important implications advancing knowledge eco-evolutionary processes impact interactions future applications precision microbiology. Important steps will be examine beyond bacterial communities, apply evolutionary modelling an increasingly sophisticated understanding unravel microbial mechanisms contribute pattern. This serves gateway experimental, conceptual quantitative themes outlines opportunities ripe investigation diversity disciplines.

Ecological stability of microbial communities in Lake Donghu regulated by keystone taxa

Ecological Indicators, Год журнала: 2022, Номер 136, С. 108695 - 108695

Seasonal variations of environmental factors generally result in considerable changes microbiomes, yet we still lack a clear understanding how microbial communities maintain their ecological stability. Here, analyze long-term (nine years) high-throughput sequencing dataset by network analysis to illustrate the stability varies among seasons lake ecosystems. The results showed that networks were distinctly different seasons, and most complex autumn exhibited highest We found strong connecting structures microbes (large modules) significantly (P < 0.05) correlated with water temperature pH, which would negatively affect keystone taxa destabilize communities. more stable removal unstable networks. Moreover, specific due filtering relevant interspecific interactions. These suggested seasonal could influence community via regulation taxa. Thus, be used as indicators reflect findings improve our co-occurrence patterns reveal mechanism aquatic

Abstract Global warming may alter microbially mediated ecosystem functions through reshaping of microbial diversity and modified interactions. Here, we examined the effects 5‐year experimental on different hierarchical groups in a coastal nontidal soil ecosystem, including prokaryotes (i.e., bacteria archaea), fungi, Cercozoa, which is widespread phylum protists. Warming significantly altered structure prokaryotic fungal communities additionally decreased complexity network fragmented cercozoan network. By using Inter‐Domain Ecological Network approach, cross‐trophic interactions among prokaryotes, Cercozoa were further investigated. Under warming, cercozoan–prokaryotic fungal–prokaryotic bipartite networks simplified, whereas cercozoan–fungal became slightly more complex. Despite simplification network, strengthened synergistic between saprotrophic fungi certain groups, such as Bacteroidetes, retained these phyla within under warming. In addition, community quite stable conditions, stabilized or Additionally, found affected by environmental stress salinity pH) nutrients.

Abstract In the deep ocean symbioses between microbes and invertebrates are emerging as key drivers of ecosystem health services. We present a large-scale analysis microbial diversity in deep-sea sponges (Porifera) from scales sponge individuals to basins, covering 52 locations, 1077 host translating into 169 species (including understudied glass sponges), 469 reference samples, collected anew during 21 ship-based expeditions. demonstrate impacts abundance status, geographic distance, phylogeny, physical-biogeochemical environment microbiome composition, descending order relevance. Our study further discloses that fundamental concepts microbiology apply robustly across distances >10,000 km. Deep-sea microbiomes less complex, yet more heterogeneous, than their shallow-water counterparts. underscores uniqueness each ground based on which we provide critical knowledge for conservation these vulnerable ecosystems.

Human civilization relies on estuaries, and many estuarine ecosystem services are provided by microbial communities. These include high rates of primary production that nourish harvests commercially valuable species through fisheries aquaculture, the transformation terrestrial anthropogenic materials to help ensure water quality necessary support recreation tourism, mutualisms maintain blue carbon accumulation storage. Research ecology underlies in estuaries has expanded greatly across a range environments, including water, sediment, biofilms, biological reefs, stands seagrasses, marshes, mangroves. Moreover, application new molecular tools improved our understanding diversity genomic functions microbes. This review synthesizes recent research habitats contributions microbes food webs, elemental cycling, interactions with plants animals, highlights novel insights advances genomics.
