Environmental degradation has the potential to alter key mutualisms that underlie structure and function of ecological communities. How microbial communities associated with fishes vary across populations in relation habitat characteristics remains largely unknown despite their fundamental roles host nutrition immunity. We find significant differences gut microbiome composition a facultative coral-feeding butterflyfish (Chaetodon capistratus) Caribbean reefs differ markedly live coral cover (∼0-30%).

ABSTRACT Despite the relevance of submarine groundwater discharge (SGD) for ocean biogeochemistry, microbial dimension SGD remains poorly understood. can influence marine communities through supplying chemical compounds and microorganisms, in turn, microbes at land–ocean transition zone determine chemistry reaching ocean. However, compared with inland groundwater, little is known about coastal aquifers. Here, we review state art SGD, emphasis on prokaryotes, identify current challenges future directions. Main include improving diversity description microbiota, characterized by ultrasmall, inactive novel taxa, high ratios sediment-attached versus free-living cells. Studies should explore dynamics their role cycles aquifers, bidirectional dispersal seawater bacterioplankton responses to SGD. This will require not only combining sequencing methods, visualization linking taxonomy activity but also considering entire groundwater–marine continuum. Interactions between traditionally independent disciplines (e.g. hydrogeology, ecology) are needed frame study terrestrial aquatic microorganisms beyond limits presumed habitats, foster our understanding processes biogeochemical cycles.

Abstract Chlamydiae is a bacterial phylum composed of obligate animal and protist endosymbionts. However, other members the Planctomycetes–Verrucomicrobia–Chlamydiae superphylum are primarily free living. How transitioned to an endosymbiotic lifestyle still largely unresolved. Here we reconstructed species relationships modelled genome evolution. Gene content reconstruction from 11,996 gene families suggests motile facultatively anaerobic last common ancestor that had already gained characteristic endosymbiont genes. Counter expectations for streamlining in strict endosymbionts, detected substantial gain within Chlamydiae. We found divergence energy metabolism aerobiosis observed extant lineages emerged later during chlamydial In particular, metabolic aerobic genes more metabolically versatile protist-infecting chlamydiae were gained, such as respiratory chain complexes. Our results show complexity can increase evolution, adding additional perspective understanding symbiont evolutionary trajectories across tree life.

Climate change is turning formerly pristine ecosystems into ever-changing states, causing major disturbance and biodiversity loss. Such impacted marine organisms exhibit clear microbiome shifts that alter their function. Microbiome-targeted interventions appear as feasible tools to support organismal ecosystem resilience recovery by restoring symbiotic interactions thwarting dysbiotic processes. However, restoration rehabilitation are perceived drastic measures, since they ‘natural relationships’. What missing from this notion microbiomes already drastically differ any pre-anthropogenic state. As such, our perception definition of even ‘pristine states’ may in fact represent an disturbed/derived condition. Following this, we argue rehabilitating essential mitigate decline.
