Sponge-derived matter is assimilated by coral holobionts [PDF]

Communications Biology, 2023
Coral reef biodiversity is maintained by a complex network of nutrient recycling among organisms. Sponges assimilate nutrients produced by other organisms like coral and algae, releasing them as particulate and dissolved matter, but to date, only a ...

Relative abundance of nitrogen cycling microbes in coral holobionts reflects environmental nitrate availability [PDF]

Royal Society Open Science, 2021
Recent research suggests that nitrogen (N) cycling microbes are important for coral holobiont functioning. In particular, coral holobionts may acquire bioavailable N via prokaryotic dinitrogen (N2) fixation or remove excess N via denitrification activity.

Meta-transcriptomic comparison of two sponge holobionts feeding on coral- and macroalgal-dissolved organic matter [PDF]

BMC Genomics, 2022
Background Sponge holobionts (i.e., the host and its associated microbiota) play a key role in the cycling of dissolved organic matter (DOM) in marine ecosystems.

Heatwave-driven persistent microbes threaten the resilience of Mediterranean coral holobionts [PDF]

Environmental Microbiome
Background The climate crisis poses a serious threat to octocorals in the Mediterranean Sea as marine heatwaves (MHWs) not only impair coral metabolism but also disrupt the complex symbiosis between the coral host and its microbiome. Since octocorals are

Coral microbiome in estuary coral community of Pearl River Estuary: insights into variation in coral holobiont adaptability to low-salinity conditions [PDF]

BMC Microbiology
Background Low salinity is a crucial environmental stressor that affects estuarine coral ecosystems considerably. However, few studies have focused on the effects of low-salinity conditions on coral-associated microorganisms and the adaptability of coral

Elucidating gene expression adaptation of phylogenetically divergent coral holobionts under heat stress [PDF]

Nature Communications, 2021
As corals struggle to survive under climate change, it is crucial to know whether they can withstand increasing seawater temperatures. Using a controlled thermal stress experiment across three divergent coral holobionts, this study examines ...

The gut within: reframing the coral gastrovascular cavity as a discrete anaerobic microbial ecosystem [PDF]

Applied and Environmental Microbiology
Coral holobionts are typically studied at colony or fragment scale, erasing the spatial context of the microenvironments which microbial life occupies. Recent microsensor work (Q. Zhang, E. Bollati, and M. Kühl, Appl Environ Microbiol 92:e02441-25, 2026,

Extracellular enzymatic activities of octocorals and scleractinian corals under environmental stress [PDF]

Scientific Reports
Extracellular enzymes, released by coral holobionts (coral host, symbiotic dinoflagellates and associated microorganisms) are involved in nutrient cycling and can serve as diagnostic indicators of coral health and reef ecosystem functionality.

Stress‐Resistant Symbiodiniaceae and Diverse Bacterial Communities Promote Coral Persistence in Variable, Multi‐Stressor Environments [PDF]

Ecology and Evolution
Coral holobionts maintain complex symbioses, which can be influenced by global and local stressors. However, the role of coral‐associated bacterial and algal (Symbiodiniaceae) communities in facilitating coral persistence in variable and extreme, multi ...

Energetic and carbon allocation strategies shape coral holobiont responses to combined thermal and nutrient stress [PDF]

Frontiers in Microbiology
Climate change and coastal eutrophication increasingly threaten coral reefs, yet their combined impact on coral holobionts remains poorly understood. This study examined the physiological response and carbon budget of two holobionts (Galaxea fascicularis
