Abstract The waters surrounding coral reef ecosystems are generally poor in nutrients, yet their levels of primary production comparable with those reported from tropical rain forests. One explanation this paradox is the efficient cycling nutrients between host, its endosymbiotic alga Symbiodinium and a wide array microorganisms. Despite importance for animals' fitness, early life stages initial establishment partnerships microbes involved these processes has received little scrutiny to...
Coral-associated microbial communities from three coral species (Pocillopora damicornis, Acropora tenuis and Favites abdita) were examined every 3 months (January, March, June, October) over a period of 1 year on Ningaloo Reef, Western Australia. Tissue corals was collected throughout the additional sampling mucus seawater samples performed in January. also obtained October P. damicornis colonies Rottnest Island off Perth, 1200 km south to provide comparisons between coral-microbial...
Bacteria associated with three coral species, Acropora tenuis, Pocillopora damicornis and Tubastrea faulkneri, were assessed before after mass spawning on Ningaloo Reef in Western Australia. Two colonies of each species sampled the event two additional samples collected for P. planulation. A variable 470 bp region 16 S rRNA gene was selected pyrosequencing to provide an understanding potential variations coral-associated bacterial diversity community structure. Bacterial increased all as by...
Abstract Massive proliferations of scyphozoan jellyfish considerably affect human industries and irreversibly change food webs. Efforts to understand the role in marine ecosystems are based on a life cycle model described 200 years ago. According this paradigm pelagic medusae is considered seasonal alternates with benthic polyp stage from which it derives. However, we provide evidence that a) occurrence several species not restricted season year, they overwinter, b) polyp- medusa generations...
The key to 650 million years of evolutionary success in jellyfish is adaptability: with alternating benthic and pelagic generations, sexual asexual reproductive modes, multitudes body forms a cosmopolitan distribution, are likely have established plenitude microbial associations. Here we explored bacterial assemblages the scyphozoan Chrysaora plocamia (Lesson 1832). Life stages involved propagation through cyst formation, i.e., mother polyp, its dormant cysts (podocysts), polyps recently...
Herbivory is particularly intense in tropical benthic communities, suggesting preference of constitutive, rather than inducible, anti‐herbivory defense. The objective the study was to examine whether anti‐herbivore defenses red alga Hypnea pannosa J. Agardh and brown algae Sargassum asperifolium Hering G. Martens ex Cystoseira myrica (S.G. Gmelin) C. could be induced subsequently reduced response grazing by amphipod Cymadusa filosa Savigny. During a 14‐day treatment phase, were exposed or...
Bacterial assemblages associated with the hermatypic corals Pocillopora damicornis and P. verrucosa, surrounding seawater sediment at six coral reef sites in north section of Tropical Eastern Pacific were assessed using MiSeq Illumina sequencing V4 region 16S rDNA. The bacterial microbiota both species, stable to seasonal variations. between same substrates not significantly different from each other sampled. Interestingly, composition within site was different, or not, depending on...
Abstract The bacterium Vibrio ordalii is best known as the causative agent of vibriosis outbreaks in fish and thus recognized for generating serious production losses aquaculture systems. Here we report first time on isolation genome sequencing phage vB_VorS-PVo5, infectious to ATCC 33509. features well complete sequence annotation are described; vB_VorS-PVo5 consists a lineal double stranded DNA totaling ~ 80.6 Kb length. Considering its ability lyse 33509, likely gain importance future...
In a recent comment, Morandini and colleagues raised concerns about our article, The elusive life cycle of scyphozoan jellyfish – metagenesis revisited. main goal article was to motivate scientists pursue an improved understanding bloom-forming through critical examination the current model, not overthrow long-standing paradigm. Structure Scientific Revolutions, by Thomas S. Kuhn, describes that for well-integrated members particular discipline, paradigm in science might be so conclusive...
Ruminant mammals extract nutrients from plant-based food through fermentation in the rumen; fiber and starch are pre-digested by microorganisms methane is produced as a by-product, which released into atmosphere acts potent greenhouse gas. In an effort to reduce enteric methanogenesis, dietary additives for ruminants have been investigated, marine macroalgae proven particularly promising, e.g., inclusion of 0.2% dry matter red alga A. taxiformis cow feed decreased vivo production up 98%....
