(Submitter supplied) Thermal history plays a role in the response of corals to subsequent heat stress. Prior heat stress can have a profound impact on later thermal tolerance, but the mechanism for this plasticity is not clear. The understanding of gene expression changes behind physiological acclimatization is critical in forecasts of coral health in impending climate change scenarios. Acropora millepora fragments were preconditioned to sublethal bleaching threshold stress for a period of 10 days; this prestress conferred bleaching resistance in subsequent thermal challenge, in which non-preconditioned coral bleached. more...

(Submitter supplied) The declining health of coral reefs worldwide is likely to intensify in response to continued anthropogenic disturbance from coastal development, pollution, and climate change. In response to these stresses, reef-building corals may exhibit bleaching, which marks the breakdown in symbiosis between coral and zooxanthellae. Mass coral bleaching due to elevated water temperature can devastate coral reefs on a large geographic scale. more...

(Submitter supplied) The metabolic bases of the interaction between the coral Acropora millepora and its dinoflagellate symbiont were investigated by comparing gene expression levels under light and dark conditions at the whole transcriptome level. Among the differentially expressed genes identified, a suite of genes involved in cholesterol transport was found to be up-regulated under light conditions, confirming the significance of this compound in the coral symbiosis. more...

(Submitter supplied) Coral populations have declined worldwide largely due to increased sea surface temperatures. Recovery of coral populations depends in part upon larval recruitment. Many corals reproduce during the warmest time of year when further increases in temperature can lead to low fertilization rates of eggs and high larval mortality. Microarray experiments were designed to capture and assess variability in the thermal stress responses of Acropora palmata larvae from Puerto Rico. more...

(Submitter supplied) Purpose: Corals are major sources of dimethylsulphoniopropionate (DMSP), a compound that plays a central role in the global sulphur cycle. While DMSP biosynthesis pathways have been investigated in plants and algae, the molecular basis for its production by corals is unknown. Given its potential role as an osmolyte, the effect of salinity stress on levels of DMSP was investigated in both adults and juveniles (lacking photosynthetic symbionts) of the coral Acropora millepora. more...

(Submitter supplied) Southern California (USA) populations of the intertidal marine snail Chlorostoma (formerly Tegula) funebralis are generally exposed to higher air and water temperatures than northern California populations. Previous studies have shown that southern populations are more tolerant of heat stress than northern populations. To assess the potential role of gene regulation in these regional differences, we examined transcriptome responses to thermal stress in two southern and two northern populations of C. more...

(Submitter supplied) Subspecies of the Atlantic killifish, Fundulus heteroclitus, differ in their maximum thermal tolerance. To determine whether there is a link between the heat shock response (HSR) and maximum thermal tolerance, we exposed 20ºC acclimated killifish from these subspecies to a 2hr heat shock at 34ºC and examined gene expression during heat shock and recovery using real time quantitative PCR and a heterologous cDNA microarray designed for salmonid fishes. more...

(Submitter supplied) In Drosophila larvae, acquired synaptic thermotolerance following heat shock has previously been shown to correlate with the induction of heat shock proteins (Hsps) including HSP70. We tested the hypothesis that synaptic thermotolerance would be significantly diminished in a temperature-sensitive strain (hsf4) which has been reported not to be able to produce inducible Hsps in response to heat shock. more...

(Submitter supplied) Sargassum is one of the most diverse brown algal genus with more than 150 known species, mostly benthic and few pelagic species. They contribute significantly to global primary production and serve as important habitat for wide range of marine organisms. Sargassum vulgare is one of the dominant habitat forming species along Mediterranean coast. Despite their huge ecological importance, it is relatively unknown how they will respond under future global climate change scenario. more...

(Submitter supplied) Ocean acidification, resulting from the dissolution of excess CO2 produced by humans into the ocean, is predicted to impact a broad variety of marine taxa, particularly calcifying animals such as the thecosome (shelled) pteropods. To achieve a better understanding of the mechanisms of pteropod calcification and physiological compensation for high CO2 exposure, we investigated the transcriptomic responses of Clio pyramidata, a cosmopolitan diel migratory thecosome. more...

(Submitter supplied) We sequenced complementary DNA created from white muscle messenger RNA in juvenile blue rockfish and performed a differential gene expression analysis to describe the fishes' responses to the global change-related stressors of high pCO2 (low pH) and hypoxia (low dissolved oxygen, DO). To examine gene expression over ecologically realistic timescales that emulate the duration of spring upwelling events in the California Current ecosystem, we collected and sequenced samples after 12 h, 24 h and two weeks of exposure to four treatments: control (pH≈8.0, pCO2≈400μatm, DO≈8 mg/L), high pCO2 (pH≈7.6, pCO2≈1200μatm, DO≈8 mg/L), hypoxic (pH≈8.0, pCO2≈400μatm, DO≈4 mg/L), and combined high pCO2/hypoxic (pH≈7.6, pCO2≈1200μatm, DO≈4 mg/L).

(Submitter supplied) For many organisms the ability to cold acclimate with the onset of seasonal cold has major implications for their fitness. In insects, where this ability is widespread, the physiological changes associated with increased cold tolerance have been well studied. Despite this, little work has been done to trace changes in gene expression during cold acclimation that lead to an increase in cold tolerance. more...
