Article
Full-text available
Fish gastro-intestinal system harbours diverse microbiomes that affect the host's digestion, nutrition and immunity. Despite the great taxonomic diversity of fish, little is understood about fish microbiome and the factors that determine its structure and composition. Damselfish are important coral reef species that play pivotal roles in determinin...

Full-text available
At present our knowledge on the compartmentalization of coral holobiont microbiomes is highly skewed towards the millimetre-thin coral tissue, leaving the diverse coral skeleton microbiome underexplored. Here, we present a genome-centric view of the skeleton of the reef-building corals' Porites lutea and Isopora palifera , through a compendium of ~...
Article
One of the most widespread coral diseases linked to anthropogenic activities and recorded on reefs worldwide is characterized by anomalous growth formations in stony corals, referred to as coral growth anomalies (GAs). The biological functions of GA tissue include limited reproduction, reduced access to resources, and weakened ability to defend aga...

Full-text available
The coral skeleton harbours a diverse community of bacteria and microeukaryotes exposed to gradients of light, O 2 and pH, but how such physicochemical gradients affect the coral skeleton microbiome remains unclear. We employed chemical imaging of O 2 and pH, hyperspectral reflectance imaging and spatially explicit taxonomic and functional microbio...

Fish gastro-intestinal system harbours diverse microbiomes that affect the host’s digestion, nutrition and immunity.

Article
Ostreobium is a siphonous green alga in the Bryopsidales (Chlorophyta) that burrows into calcium carbonate (CaCO3) substrates. In this habitat, it lives under environmental conditions unusual for an alga (i.e., low light and low oxygen) and it is a major agent of carbonate reef bioerosion. In coral skeletons, Ostreobium can form conspicuous green b...

Full-text available
The success of tropical scleractinian corals depends on their ability to establish symbioses with microbial partners. Host phylogeny and traits are known to shape the coral microbiome, but to what extent they affect its composition remains unclear. Here, by using 12 coral species representing the complex and robust clades, we explored the influence...
Article
Full-text available
This study investigates the effects of long-term exposure to OA on skeletal parameters of four tropical zooxanthellate corals naturally living at CO2 seeps and adjacent control sites from two locations (Dobu and Upa Upasina) in the Papua New Guinea underwater volcanic vent system. The seeps are characterized by seawater pH values ranging from 8.0 t...

The success of tropical scleractinian corals depends on their ability to establish symbioses with microbial partners. Host traits and evolution are known to shape the coral microbiome, but to what extent they affect its composition remains unclear. Here, by using twelve coral species representing the complex and robust clades, we show that function...
Article
Full-text available
The limestone skeleton of Scleractinian corals is a complex and intricate environment consisting of an array of ecological microniches, which harbour a vast microbial community. In addition, recent studies have demonstrated that endolithic microbes play a variety of important ecological roles. Here, we use a combination of metabarcoding of the smal...
Article
The green alga Ostreobium is an important coral holobiont member, playing key roles in skeletal decalcification and providing photosynthate to bleached corals that have lost their dinoflagellate endosymbionts. Ostreobium lives in the coral’s skeleton, a low-light environment with variable pH and O2 availability. We present the Ostreobium nuclear ge...

The responses of corals and other marine calcifying organisms to ocean acidification (OA) are variable and span from no effect to severe responses. Here we investigated the effect of long-term exposure to OA on skeletal parameters of four tropical zooxanthellate corals living at two CO 2 vents in Papua New Guinea, namely in Dobu and Upa Upasina. Th...

Coral microbial ecology is a burgeoning field, driven by the urgency of understanding coral health and slowing reef loss due to climate change. Coral resilience depends on its microbiota, and both the tissue and the underlying skeleton are home to a rich biodiversity of eukaryotic, bacterial and archaeal species that form an integral part of the co...

Article
Coral age can be strictly related to size, but processes like fragmentation, fusion, and partial colony mortality can decouple this relationship. When these phenomena are negligible, such as in solitary corals, age-based growth and population dynamics models can be used. In this study, the population size, structure, and growth rates of the tempera...
Article
Correlations between environmental parameters (depth temperature and solar radiation) and growth parameters (bulk skeletal density, linear extension rate and net calcification rate) of the solitary azooxanthellate coral, Caryophyllia inornata, were investigated along an 8° latitudinal gradient on the western Italian coasts. Net calcification rate c...
Article
The ecology of scleractinian corals may be understood through comparisons between population demographic data and environmental parameters. Growth (growth constant and maximum size) and demographic parameters (population structure stability, instantaneous mortality rate, average age of individuals, percentage of immature individuals, age at maximum...

Question
Hello everyone,
I was wondering if anybody tested the reliability of homemade RNAlater, and if it is more or less efficient than commercially available ones.
Thanks
Francesco
Question
Hello everyone,
I am running variation partitioning (using cca instead of rda) and cca from the r package vegan.
Both analyses are run on the same dataset, but I get different results in terms of the variation of the dataset that the two analyses explain.
I wondered if anyone can help explain why despite both analyses relying on cca I get different results.
Question
Hello everybody,
I will need to make some analyses on O2 in seawater and to calibrate my sensor I will need to go from: 0% O2 on air saturation till 120% O2 on air saturation.
Can anyone with chemistry skills give me advices on which chemicals I can use to raise and decrease the % of dissolved oxygen in seawater.
Question
HI everyone,
I am wondering if anyone already did this. I have just half plate filled with AMPLICON 16s, so I am wondering if it's possible to fill the other half with genomic DNA, and then sequencing all together.
What I am thinking is to do the 1st ILLUMINA PCR for the amplicon, and to do ShotGun for the genomic DNA, then merge those samples in the same plate and to go through the 2ND ILLUMINA PCR with the whole plate.
Did anyone do something similar before? or does anyone have thoughts to share?
Thank you
Francesco
Question
I would like to understand which light wavelengths reaches the layers inside a coral skeleton. I couldn't find anything in literature, so any help would be welcome.
