Bacterial community dynamics are linked to patterns of coral heat tolerance
TLDR
It is shown that the microbiome of reef corals is different across thermally variable habitats and changes over time when corals are reciprocally transplanted, but not for heat-tolerant corals growing in habitats with natural high heat extremes. Expand
Thermal refugia against coral bleaching throughout the northern Red Sea
TLDR
Examining historical patterns of sea surface temperature (SST) and associated anomalies (1982-2012) and compared warming trends with a unique compilation of corresponding coral bleaching records from throughout the region indicated that the northern Red Sea has not experienced mass bleaching despite intensive Degree Heating Weeks (DHW) of >15°C-weeks, and it is proposed that the region represents a thermal refuge of global importance.

Coral microbial community dynamics in response to anthropogenic impacts near a major city in the central Red Sea.
TLDR
In conclusion, microbial community response revealed a measurable footprint of anthropogenic impacts to coral ecosystems close to Jeddah, even though the corals appeared visually healthy. Expand
Biogeography and molecular diversity of coral symbionts in the genus Symbiodinium around the Arabian Peninsula
TLDR
This study characterizes Symbiodinium diversity around the Arabian Peninsula, which contains some of the most thermally diverse and understudied reefs on Earth, to serve as a baseline for further exploration into the effects of environmental change on host–symbiont pairings and the identification and ecological significance of symbiont types from regions already experiencing ‘Future Ocean’ conditions.

SymPortal: A novel analytical framework and platform for coral algal symbiont next‐generation sequencing ITS2 profiling
TLDR
It is considered that SymPortal, in conjunction with ongoing large‐scale sampling and sequencing efforts, should play an instrumental role in making future sampling efforts more comparable and in maximizing their efficacy in working towards the classification of the global Symbiodiniaceae diversity. Expand
In situ observations of coral bleaching in the central Saudi Arabian Red Sea during the 2015/2016 global coral bleaching event
TLDR
Bleaching was most prevalent on inshore reefs and on shallower transects within reefs, and Coral genera with the highest levels of bleaching were also among the rarest (<1% of coral cover) in 2015. Expand
Coral bacterial community structure responds to environmental change in a host-specific manner
TLDR
Bacterial community structure responds in a coral host-specific manner upon cross-transplantation between reef sites with differing levels of anthropogenic impact and it is found that microbiomes become indistinguishable from back-transplanted controls, suggesting the ability of microbiomes to recover. Expand
Photosynthetic plasticity of endosymbionts in larger benthic coral reef Foraminifera
TLDR
The investigation of photosynthetic plasticity of different endosymbiontic algae found within LBF was investigated using pulse amplitude modulated (PAM) fluorometry to demonstrate oscillation of maximum quantum efficiencies according to the light-dark cycle. Expand
Stable mucus-associated bacterial communities in bleached and healthy corals of Porites lobata from the Arabian Seas
TLDR
It is argued that bleached corals benefit from the stable composition of mucus bacteria that resemble their healthy coral counterparts and presumably provide a conserved suite of protective functions, but monitoring of post-bleaching survival is needed to further confirm this assumption. Expand
Niche acclimatization in Red Sea corals is dependent on flexibility of host-symbiont association
TLDR
An extended concept of phenotypic plasticity of the coral holobiont is advocated, in which the scleractinian host either associates with a specific Symbiodinium type with a broad physiological tolerance, or the host-symbiont pairing is more flexible to accommodate for different symbiont associations, each adapted to specific environmental settings.
