Abstract Although the early coral reef-bleaching warning system (NOAA/USA) is established, there no feasible treatment that can minimize temperature bleaching and/or disease impacts on corals in field. Here, we present first attempts to extrapolate widespread and well-established use of bacterial consortia protect or improve health other organisms (e.g., humans plants) corals. Manipulation coral-associated microbiome was facilitated through addition a consortium native (isolated from Pocillopora damicornis surrounding seawater) putatively beneficial microorganisms for (pBMCs), including five Pseudoalteromonas sp., Halomonas taeanensis Cobetia marina-related species strains. The results controlled aquarium experiment two regimes (26 °C 30 °C) four treatments (pBMC; pBMC with pathogen challenge – Vibrio coralliilyticus, VC; challenge, control) revealed ability partially mitigate bleaching. Significantly reduced coral-bleaching metrics were observed pBMC-inoculated corals, contrast controls without addition, especially challenged which displayed strong signs as indicated by significantly lower photopigment contents Fv/Fm ratios. structure community also differed between specific bioindicators correlated inoculated sp.)

Fungi in the Marine Environment: Open Questions and Unsolved Problems

mBio, Год журнала: 2019, Номер 10(2)

Terrestrial fungi play critical roles in nutrient cycling and food webs can shape macroorganism communities as parasites mutualists. Although estimates for the number of fungal species on planet range from 1.5 to over 5 million, likely fewer than 10% have been identified so far.

Responses of Coral-Associated Bacterial Communities to Local and Global Stressors

Frontiers in Marine Science, Год журнала: 2017, Номер 4

The microbial contribution to ecological resilience is still largely overlooked in coral reef ecology. Coral-associated bacteria serve a wide variety of functional roles with reference the host, and thus, composition overall microbiome community can strongly influence health survival. Here, we synthesize findings recent studies (n=45) that evaluated impacts top three stressors facing reefs, climate change, water pollution overfishing, on structure diversity. Contrary species losses are typical many communities under stress, here show richness tends be higher rather than lower for stressed corals (i.e. ~60% cases), regardless stressor. Microbial responses stress were taxonomically consistent across stressors, specific taxa typically increasing abundance (e.g. Vibrionales, Flavobacteriales, Rhodobacterales, Altermonadales, Rhizobiales, Rhodospirillales Desulfovibrionales) others declining Oceanosprillales). Emerging evidence also suggests may increase beta diversity amongst colonies, potentially reflecting reduced ability host regulate its microbiome. Moving forward, will need discern implications stress-induced shifts hosts able use identify resilient corals. present supports hypothesis play important resilience, encourage focus contributions future research.

Adapting with Microbial Help: Microbiome Flexibility Facilitates Rapid Responses to Environmental Change

BioEssays, Год журнала: 2020, Номер 42(7)

Опубликована: Июнь 16, 2020

Abstract Animals and plants are metaorganisms associate with microbes that affect their physiology, stress tolerance, fitness. Here the hypothesis alteration of microbiome may constitute a fast‐response mechanism to environmental change is examined. This supported by recent reciprocal transplant experiments reef corals, which have shown adapts thermally variable habitats changes over time when transplanted into different environments. Further, inoculation corals beneficial bacteria increases tolerance. But differ in ability flexibly bacteria. How scales flexibility reflect metaorganism adaptation mechanisms discussed future directions for research pinpointed. It posited broad phenomenon contributes organisms respond change. Importantly, adapting microbial help provide an alternate route organismal facilitates rapid responses.

Considerations for maximizing the adaptive potential of restored coral populations in the western Atlantic

Ecological Applications, Год журнала: 2019, Номер 29(8)

Опубликована: Июль 23, 2019

Active coral restoration typically involves two interventions: crossing gametes to facilitate sexual larval propagation; and fragmenting, growing, outplanting adult colonies enhance asexual propagation. From an evolutionary perspective, the goal of these efforts is establish self-sustaining, sexually reproducing populations that have sufficient genetic phenotypic variation adapt changing environments. Here, we provide concrete guidelines help practitioners meet this for most Caribbean species interest. To enable persistence exposed severe selection pressure from many stressors, a mixed provenance strategy suggested: genetically unique (genets) should be sourced both locally as well more distant, environmentally distinct sites. Sourcing three four genets per reef along environmental gradients capture majority intraspecies diversity. It best propagate with one or traits are predicted valuable in future, such low partial mortality, high wound healing rate, skeletal growth bleaching resilience, infectious disease reproductive output. Some effort also reserved underperforming because grow poorly nurseries sometimes thrive once returned may harbor variants yet unrecognized value. Outplants clustered groups six successful fertilization upon maturation. Current evidence indicates translocating among distant reefs unlikely problematic population perspective but will likely substantial adaptive benefits. Similarly, inbreeding depression not concern given current practices only raise first-generation offspring. Thus, proceeding proposed management strategies even absence detailed analysis focal at sites targeted course action. These basic maximize potential reef-building corals facing rapidly environment.
