Coral larvae of A. gemmifera in responses to elevated CO2

ABSTRACT: Acidified seawater not only resulted in the less settlement of A. gemmifera embryos, but also decreased juvenile sizes and slowed the development of skeleton. The solute carriers (SLC) (membrane transport proteins) responsible for the calcium and bicarbonate transports were downregulated due to elevated CO2.

ORGANISM(S): Acropora gemmifera

The diatom Thalassiosira pseudonana grown in mesocosms at contemporary and elevated CO2 over the diel cycle

Project description:To test whether elevated CO2 , which drives seawater below pH 7.9, would shift the dynamical expression patterns diatoms in a more natural environment, we designed a controlled mesocosm study at Friday Harbor Laboratories (FHL) Ocean Acidification Environmental Laboratory (OAEL). Briefly, four independent mesocosm tanks were set up with continuous flow (10-12 mL/min) of filtered seawater from the Puget Sound to simulate mid-century (pH 7.9) and acidified oceanic conditions (pH 7.6) in duplicate. Mesocosm reservoirs were supplemented with nutrients and inoculated with T. pseudonana acclimated in FHL seawater. Mesocosms were outfitted with custom enclosures to simulate a 12:12 light:dark diel cycle. Cells for RNA extraction were sampled in the middle of the light and dark cycle and sequenced on Illumina NextSeq 500 platform.

Molecular response of the coral Acropora millepora to three settlement and/or metamorphosis induced stimuli

Project description:Two known settlement/metamorphosis inducing stimuli (crustose coralline algae, and ethanolic extract of crustose coralline algae) and one stimulus which just induces metamorphosis (LWamide) were used to stimulate competent planula larvae of the coral Acropora millepora. Samples were taken 0.5h, 4h and 12h post induction isolate the genes controlling settlement and metamorphosis in this coral.

Adaptive response of the sea urchin Paracentrotus lividus to ocean acidification at a volcanic CO2 vent’s system (Mediterranean Sea, Italy)

Project description:Ocean acidification is recognized as one of the most pervasive anthropogenic impact on marine life. A variety of responses have been highlighted in different marine organisms ranging from physiology to gene and protein expression. However, most of these studies have been performed in laboratory exposing adults or developmental stages to CO2 enriched seawater. To what extend the information obtained from these in vitro experiments may be extrapolated to a natural environment is questionable. Here, we utilized the Castello volcanic CO2 vents at Ischia as natural laboratory to study the P. lividus population living at the low pH zone (pH~7.8) compared to those of sea urchins living at control sites. Wide-ranging analyses were performed in animals collected at the acidified site, including the monitoring of their position, the determination of the physico-chemical parameters of the coelomic fluid and an in depth characterization of coelomocytes regarding the number and type of cells, Hsp70 expression, redox status and protein expression through de-novo sequencing analyses. In addition, the respiration, nitrogen metabolism, and skeletal mineralogy of urchins from the vent were examined in comparison with those from control animals. Overall these analyses allowed to understand how the sea urchins can thrive in low pH/high CO2.

Identifying Genes Associated with the Molecular Scleractinian Coral Calcification Process (Stylophora pistillata study case)

Project description:Increasing seawater’s calcium concentration has shown to increase reef building (scleractinian) coral’s calcification rates. In this way the expression of the genes that are associated with the calcification process also altered and, thus can be identified. Needless to say that the overall gene repertoire that participate in the coral calcification process and its molecular mechanisms have not yet been revealed, although sporadic genes that are related to the process have been discovered and investigated. In this study, nubbins of the Red Sea scleractinian coral, Stylophora pistillata were treated with increased calcium concentrations seawater (addition of 100 gm/L) and the genes that have been up-regulated were compared to the genes expression profile of corals with natural seawater calcium concentration. Measurements of AT were taken at mid-day (11:00) and in nighttime (23:00), to record the calcification rates of coral individuals under normal and increased calcium seawater concentrations. In order to reveal the gene involved in the calcification process, S. pistillata fragments of normal and of increased calcium concentrations were sampled for microarray RNA transcriptional profiling at two time-points (mid-day and nighttime).Results of this study have revealed that Smad genes may play a role in the coral skeletal growth apparatus. This study show that the calcification molecular mechanism is conserved Among identified genes are large group of genes that are characterized in the TGF-b/BMP signal transduction pathways which have been revealed in other organisms to participate in bone and cartilage tissue development molecular processes.
