Diversity of the Pacific Ocean coral reef microbiome

Published: June 1, 2023

Coral reefs are among the most diverse ecosystems on Earth. They support high biodiversity of multicellular organisms that strongly rely associated microorganisms for health and nutrition. However, extent coral reef microbiome diversity its distribution at oceanic basin-scale remains to be explored. Here, we systematically sampled 3 morphotypes, 2 fish species, planktonic communities in 99 from 32 islands across Pacific Ocean, assess composition biogeography. We show a very large richness compared other environments, which extrapolated all fishes corals Pacific, approximates current estimated total prokaryotic entire Microbial vary within animal biomes (coral, fish, plankton), geographically. For corals, cross-ocean patterns different those known organisms. Within each morphotype, community is always determined by geographic distance first, both island ocean scale, then environment. Our unprecedented sampling effort microbiomes, as part Tara expedition, provides new insight into global microbial diversity, factors driving their distribution, biocomplexity ecosystems.

Disparate population and holobiont structure of pocilloporid corals across the Red Sea gradient demonstrate species‐specific evolutionary trajectories

Molecular Ecology, Journal Year: 2023, Volume and Issue: 32(9), P. 2151 - 2173

Abstract Global habitat degradation heightens the need to better understand patterns of genetic connectivity and diversity marine biota across geographical ranges guide conservation efforts. Corals Red Sea are subject pronounced environmental differences, but studies so far suggest that animal populations largely connected, excepting evidence for a break between northern‐central southern regions. Here, we investigated population structure holobiont assemblage two common pocilloporid corals, Pocillopora verrucosa Stylophora pistillata , Sea. We found little differentiation in P. except southernmost site. Conversely, S. exhibited complex with within‐reef regional differentiation, line differences their reproductive mode ( is broadcast spawner brooder). Analysis genomic loci under positive selection identified 85 sites (18 which were coding sequences) distinguished from remainder population. By comparison, 128 (24 residing local adaptation at various sites. Functional annotation underlying proteins revealed putative roles response stress, lipid metabolism, transport, cytoskeletal rearrangement, ciliary function (among others). Microbial assemblages both coral species showed pervasive association microalgal symbionts genus Symbiodinium (former clade A) bacteria Endozoicomonas significant according host genotype environment. The disparity even closely related (family Pocilloporidae) highlights multispecies investigations role environment shaping evolutionary trajectories. It further emphasizes importance networks reef reserves achieve variants critical future survival ecosystems.

Systematic review of cnidarian microbiomes reveals insights into the structure, specificity, and fidelity of marine associations

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Abstract Microorganisms play essential roles in the health and resilience of cnidarians. Understanding factors influencing cnidarian microbiomes requires cross study comparisons, yet plethora protocols used hampers dataset integration. We unify 16S rRNA gene sequences from microbiome studies under a single analysis pipeline. reprocess 12,010 samples 186 studies, alongside 3,388 poriferan, 370 seawater samples, 245 cultured Symbiodiniaceae, unifying ~6.5 billion sequence reads. Samples are partitioned by hypervariable region sequencing platform to reduce variability. This systematic review uncovers an incredible diversity 86 archaeal bacterial phyla associated with Cnidaria, highlights key bacteria hosted across host sub-phylum, depth, microhabitat.
