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.

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 ...

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 ...

Understanding nitrogen dynamics in coral holobionts: comprehensive review of processes, advancements, gaps, and future directions

Frontiers in Marine Science, 2023
Coral reefs are known for being highly productive ecosystems in oligotrophic oceans, which is commonly referred to as the Darwin’s Paradox. Nitrogen is an essential component of organisms, but it limits primary productivity in most euphotic ocean ...

Seasonal Physiological Strategies Reveal Contrasting Host-Symbiont Dynamics Among Dominant Indo-Pacific Reef-Building Corals. [PDF]

Ecol Evol
Seasonal changes in coral physiology reveal distinct acclimatization strategies among reef‐building corals. Symbiotic generalists exhibit large seasonal fluctuations driven primarily by symbiont dynamics, whereas symbiotic specialists maintain stable symbiont physiology through stronger host regulation.

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.

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

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

Changes in the diversity and functionality of viruses that can bleach healthy coral [PDF]

mSphere
Coral microbiomes play a crucial role in maintaining the health and functionality of holobionts. Disruption in the equilibrium of holobionts, including bacteria, fungi, and archaea, can result in the bleaching of coral. However, little is known about the
