Metagenomic Analysis of Healthy and White Plague-Affected Mussismilia braziliensis Corals
TLDR
The results suggest that WP disease in M. braziliensis is caused by a polymicrobial consortium, and Proteobacteria, Bacteroidetes, Firmicutes, Cyanobacteria and Actinomycetes are the main groups in all healthy and WP-affected corals.
An evaluation of the use of branching fire-corals (Millepora spp.) as refuge by reef fish in the Abrolhos Bank, eastern Brazil
TLDR
It is shown that several fish species seek refuge within fire-corals in Brazil, suggesting that they may replace the functional role played by scleractinians in other regions, and fire-coral cover may be considered as an alternative instead of a critical microhabitat for fish.
Dynamics of Coral Reef Benthic Assemblages of the Abrolhos Bank, Eastern Brazil: Inferences on Natural and Anthropogenic Drivers
TLDR
The results suggest that local environmental factors such as light, depth and substrate inclination exert a stronger influence on the structure of benthic assemblages than protection from fishing.
Advanced Microbial Taxonomy Combined with Genome-Based-Approaches Reveals that Vibrio astriarenae sp. nov., an Agarolytic Marine Bacterium, Forms a New Clade in Vibrionaceae
Advances in genomic microbial taxonomy have opened the way to create a more universal and transparent concept of species but is still in a transitional stage towards becoming a defining robust
Niche distribution and influence of environmental parameters in marine microbial communities: a systematic review
TLDR
A co-occurrence network was created by calculating correlation scores between the abundances of microorganisms in metagenomes and dividing organisms into groups of taxa that have similar ecology, allowing the detection of several significant correlations that could not be observed for the taxa individually.
Biological oxygen demand optode analysis of coral reef-associated microbial communities exposed to algal exudates
TLDR
It is demonstrated that exudates from turf algae may contribute to hypoxia-induced coral stress in two different coral genera as a result of increased biological oxygen demand of the local microbial community.
Abrolhos Bank Reef Health Evaluated by Means of Water Quality, Microbial Diversity, Benthic Cover, and Fish Biomass Data
TLDR
It is concluded that ecological conditions in unprotected reefs may promote the growth and rapid evolution of opportunistic microbial pathogens and protected coral reefs have higher microbial diversity.
Microbial community diversity and physical–chemical features of the Southwestern Atlantic Ocean
TLDR
This study was the first attempt to characterize the taxonomic and functional community diversity of different water masses at SAO and compare it with the microbial community Diversity of the global ocean, and SAO had a significant portion of endemic gene diversity.
Thaumasiovibrio occultus gen. nov. sp. nov. and Thaumasiovibrio subtropicus sp. nov. within the family Vibrionaceae, isolated from coral reef seawater off Ishigaki Island, Japan.
TLDR
Thaumasiovibrio species were phylogenetically distinct from the other Vibrionaceae species based on pyrH gene sequences and the combination of catalase negative, sensitivity to vibriostatic agent O/129, and green colony formation on TCBS was the diagnostic features for the current tentative identification of this genus.
Multiple Symbiodinium Strains Are Hosted by the Brazilian Endemic Corals Mussismilia spp.
TLDR
Results indicate that Symbiodinium community dynamics shall have an important contribution for the resilience of Mussismilia spp.
