PCR survey of 50 introns in animals: Cross-amplification of homologous EPIC loci in eight non-bilaterian, protostome and deuterostome phyla
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gerard, K.; Guilloton, E.; Arnaud-haond, Sophie; Aurelle, D.; Bastrop, R.; Chevaldonne, P.; Derycke, S.; Hanel, R.; Lapegue, Sylvie; Lejeusne, C.; Mousset, Sylvain; Ramsak, A.; Remerie, T.; Viard, Frederique; Feral, Jean-pierre; Chenuil, A.
Exon Primed Intron Crossing (EPIC) markers providemolecular tools that are susceptible to be variable within specieswhile remaining amplifiable by PCR using potentially universal primers. In this studywe tested the possibility of obtaining PCR products from 50 EPIC markers on 23 species belonging to seven different phyla (Porifera, Cnidaria, Arthropoda, Nematoda, Mollusca, Annelida, Echinodermata) using 70 new primer pairs. A previous study had identified and tested those loci in a dozen species, including another phylum, Urochordata (Chenuil et al., 2010). Results were contrasted among species. The best results were achieved with the oyster (Mollusca) where 28 loci provided amplicons susceptible to contain an intron according to their size. This was...

The red coral (Corallium rubrum) transcriptome: a new resource for population genetics and local adaptation studies
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pratlong, M.; Haguenauer, A.; Chabrol, O.; Klopp, C.; Pontarotti, P.; Aurelle, D.
The question of species survival and evolution in heterogeneous environments has long been a subject for study. Indeed, it is often difficult to identify the molecular basis of adaptation to contrasted environments, and nongenetic effects increase the difficulty to disentangle fixed effects, such as genetic adaptation, from variable effects, such as individual phenotypic plasticity, in adaptation. Nevertheless, this question is also of great importance for understanding the evolution of species in a context of climate change. The red coral (Corallium rubrum) lives in the Mediterranean Sea, where at depths ranging from 5 to 600m, it meets very contrasted thermal conditions. The shallowest populations of this species suffered from mortality events linked...

Evidence for a genetic sex determination in Cnidaria, the Mediterranean red coral (Coralliumrubrum)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)

dSexual reproduction is widespread among eukaryotes, and the sex-determining processes vary greatly among species. While genetic sex determination (GSD) has been intensively described in bilaterian species, no example has yet been recorded among non-bilaterians. However, the quasi-ubiquitous repartition of GSD among multicellular species suggests that similar evolutionary forces can promote this system, and that these forces could occur also in non-bilaterians. Studying sex determination across the range of Metazoan diversity is indeed important to understand better the evolution of this mechanism and its lability. We tested the existence of sexlinked genes in the gonochoric red coral (Corallium rubrum, Cnidaria) using restriction site-associated DNA...

Highly contrasted responses of Mediterranean octocorals to climate change along a depth gradient
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pivotto, I. D.; Nerini, D.; Masmoudi, M.; Kara, H.; Chaoui, L.; Aurelle, D.
Climate change has a strong impact on marine ecosystems, including temperate species. Analysing the diversity of thermotolerance levels within species along with their genetic structure enables a better understanding of their potential response to climate change. We performed this integrative study on the Mediterranean octocoral Eunicella cavolini, with samples from different depths and by means of a common garden experiment. This species does not host photosynthetic Symbiodinium, enabling us to focus on the cnidarian response. We compared the thermotolerance of individuals from 20 m and 40 m depths from the same site and with replicates from the same colony. On the basis of an innovative statistical analysis of necrosis kinetics and risk, we demonstrated...

lagoonal sand smelts ( &lt;Atherina lagunaea&gt;, teleostei, atherinidae) inhabit marine shallow waters of the coasts of djerba island (Tunisia)
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Bouriga, N.; Selmi, S.; Aurelle, D.; Barthelemy, R.; Quignard, J-P.; Trabelsi, M.
Atherina boyeri de la Méditerranée est un complexe hautement polymorphe ayant un génotype capable d’une réponse phénotypique flexible. Elle peut rapidement adapter les traits  de sa morphologie à des environnements allant des eaux douces aux eaux saumâtres côtières polyhalines et aux eaux océaniques. Les travaux de recherche réalisés, en Méditerranée, sur ce complexe ont permis de le scinder en trois espèces. Deux espèces marines (Atherina boyeri et Atherina punctata) et une espèce qui peuplent les lagunes et les côtes des îles Kerkennah (Atherina lagunae) (Trabelsi et al. 2009). Dans le présent travail l’analyse d’une portion du gène cytochrome b a  été utilisée  pour étudier les variations génétiques d’une population d’athérine, prélevée des côtes de...
