Karang hidup bersimbiosis tidak hanya dengan zooxanthella tetapi juga berbagai komunitas mikroorganisme yaitu bakteri. Keberadaan bakteri di karang berperan sebagai penyedia nutrient bagi hewan karang. 
 Salah satu adaptasi yang dilakukan oleh terhadap perubahan lingkungan mensekresikan mukus. Mukus memberikan ruang jenis bakteri.

Coral reefs are experiencing a dramatic loss of hard coral abundance and associated habitat structure from myriad local global factors. Here, utilizing U–Th radiometric age-dating death assemblages, we investigated patterns mortality the eastern margin Red Sea along latitudinal gradient (Yanbu, 24o N; Thuwal, 22o Al-Lith, 19o Farasan Banks, 18o N) in 2018 2019. In all four regions, ages situ de...

Coral bleaching, cyclones, outbreaks of crown-of-thorns seastar, and reduced water quality (WQ) threaten the health resilience coral reefs. The cumulative impacts from multiple acute chronic stressors on “reef State” (i.e., total cover) Performance” deviation expected rate cover increase) have rarely been assessed simultaneously, despite their management relevance. We evaluated dynamics (total ...

Abstract Molecular phylogenetics has fundamentally altered our understanding of the taxonomy, systematics and biogeography corals. Recently developed phylogenomic techniques have started to resolve species-level relationships in diverse ecologically important genus Acropora, providing a path taxonomy this notoriously problematic group. We used targeted capture dataset (2032 loci) investigate sy...

We report an in-depth survey of next-generation DNA sequencing of ciliate diversity and community structure in two permanently ice-covered McMurdo Dry Valley lakes during the austral summer and autumn (November 2007 and March 2008). We tested hypotheses on the relationship between species richness and environmental conditions including environmental extremes, nutrient status, and day length. On...

Eight years ago (2007), the distribution and status of Acropora palmata was quantified throughout Los Roques archipelago in Venezuela. The aim was to produce a baseline study for this species which combined population genetics with demographic data. The results highlighted that A. palmata had the potential to recover in at least 6 out of 10 sites surveyed. Recovery potential was assumed to be h...

The induction of larval attachment and metamorphosis of benthic marine invertebrates is widely considered to rely on habitat specific cues. While microbial biofilms on marine hard substrates have received considerable attention as specific signals for a wide and phylogenetically diverse array of marine invertebrates, the presumed chemical settlement signals produced by the bacteria have to date...

Despite a wealth of information on sexual reproduction in scleractinian corals, there are regional gaps in reproductive records. In the Gulf of the Oman in the Arabian Sea, reproductive timing was assessed in four common species of broadcast spawning corals using field surveys of gamete maturity and aquarium observations of spawning activity. The appearance of mature gametes within the same mon...

Peritrich ciliates are commonly found as epibionts, colonizing living organisms, or attached to non-living substrates in freshwater, estuarine and marine environments. Several species of peritrich epibionts are obligate, which means that they are able to only colonize other organisms, while others are facultative attaching to living or non-living substrates. The peritrich Zoothamnium intermediu...
