Project description:Background biology: Global warming has accelerated in recent decades, with the Arctic warming 2–3 times faster than the global average. As a result boreal species are expanding into the Arctic, at a pace reflecting environmental warming. Nevertheless, the poleward expansion of boreal marine species is restricted by their ability to tolerate low water temperatures, and in the case of intertidal species, sub-zero air temperatures during winter. In Greenland, however, the number of days with extreme sub-zero air temperatures has decreased by more than 50% since the 1950’s, suggesting that the low air temperature constraint is weakening. Although boreal intertidal species could potentially benefit from this warmer climate to establish populations in the Arctic, recent work has shown that local intertidal summer air temperatures in Greenland can exceed 36°C. This temperature is above the thermoregulatory capacity of many boreal intertidal species, including the highly abundant blue mussel Mytilus edulis. Therefore will further colonisation of M. edulis in Greenland be inhibited by the increasingly warm summer temperatures. Aim of experiment: Intertidal animals (Greenland blue mussel M. edulis) were sampled in situ on the first warm days of the year from the inner (warmer) and outer (cooler) regions of the Godthåbsfjorden around Nuuk (64°N) to examine the fjord temperature gradient effect. In addition, subtidal M. edulis were also collected and subjected to two acute temperature shocks of 22 and 32°C, which represented common and extreme summer air temperatures for intertidal habitats near Nuuk.

Project description:Blue mussel larvae were fed, in a first group, a balanced diet of essential fatty acids (EFAs) provided by a cocktail diet (COC) from three algal species. Larvae were cultured in three separate tanks from hatching, 0 day post-fertilization (DPF) until 42 DPF. Treated larvae were fed a deficient diet (Tiso) that contains low levels of arachidonic acid (AA) and eicosapentaenoic acid (EPA), two EFAs necessary for larval development, performance, and survival. The goal is to identify coordinated patterns of gene expression and understand their predictive function in relation to growth and mortality during early developmental stages of the blue mussel Mytilus edulis. In order to understand the mechanisms by which growth and survival drive an organism to the full range of its adaptation, we de novo assembled of the mussel transcriptome during early development using next-generation sequencing (NGS) technology, then designed customized microarrays targeting every developmental stage, which encompass major transitions in tissue organization of the fast-evolved blue mussel

Project description:This project is aiming to examine the molecular response of the blue mussel (Mytilus edulis) to increased air temperatures and reduced salinity under laboratory conditions. There are 5 treatment groups (n=5), with group A representing the control (salinity 23percent salinity and temperature 5 degree celsius), group B ( 23percent salinity 30 degree celsius), group C (23percent salinity 33 degree celsius), group D (15percent salinity 5 degree celsius), group E (15percent salinity 30 degree celsius), group F (15percent salinity33 degree celsius), group G (5percent salinity 5 degree celsius).

Project description:Transcriptional profiling of the mantle tissue across the four stages of male gonads development (winter peak) in a natural population of the marine mussel Mytilus galloprovincialis sampled in the Bizerta Lagoon, Tunisia, across November 2007 -March 2008. Background: Seasonal environmental changes may affect the physiology of Mytilus galloprovincialis (Lam.), an intertidal filter-feeder bivalve occurring commonly in Mediterranean and Atlantic coastal areas. We investigated seasonal variations in relative transcript abundance of the digestive gland and the mantle (gonads) of males and females. To identify gene expression trends, we used a medium-density cDNA microarray (1.7 K probes) in dual-color competitive hybridization analyses. Results: Hierarchical clustering of digestive gland microarray data showed two main branches, distinguishing profiles associated with the “hot” months (May–August) from the other months. Genes involved in chitin metabolism, associated with mussel nutrition and digestion, showed higher expression during summer. Moreover, we found different gene expression patterns in the digestive glands of males and females during the four stages of mussel gonadal development. Microarray data from gonadal transcripts also displayed clear patterns during the different developmental phases with peak relative mRNA abundance at the ripe phase (stage III) for both sexes. Conclusion: These data showed a clear temporal pattern in gene expression profiles of mussels sampled over an annual cycle. Physiological response to thermal variation, food availability, and reproductive status across months may contribute to variation in gene expression.
