Résumé : The tropical seabass Lates calcarifer was introduced in Tahiti in 1984 and then was domesticated without other introduction. Three successive generations have been obtained in captivity. Tissue samples of the 38 animaIs which represent the total Tahitian broodstock were preserved in alcohol to be genotyped with four microsatellite markers (Yue et al., 2001). Three of four described markers were successfully transferred to the laboratory of genetics of Tahiti (marker LcaM01, LcaM02, LcaM03), as the revelation technology available locally did not allow the use of LcaM04 in routine. The results show that the genetic diversity of the tahitian broodstock is not equivalent of the one of the species, which could be explained by the small size of the founder population, which is consistant with the history of the Tahitian population. The structuration of the 4th generation into several batches obtained from different parents appears to be the minimum management procedure to limit inbreeding.
Le loup tropical Lates calcarifer a été introduit à Tahiti en 1984 puis domestiqué sans apport d'animaux extérieurs. Trois générations successives ont été obtenues en captivité. Des prélèvements de tissus sur les 38 géniteurs qui constituent l'intégralité du stock de reproducteurs tahitiens sont conservés dans l'alcool pour être génotypés à l'aide de quatre marqueurs microsatellites (Yue et al., 2001). Trois des quatre marqueurs décrits ont pu être transférés avec succès au laboratoire de génétique de Tahiti (marqueurs LcaM01, LcaM02, LcaM03), la technique de révélation disponible localement ne permettant pas d'utiliser LcaM04 en routine. Les résultats montrent qu'on ne dispose pas à Tahiti de toute la variabilité génétique de l'espèce, ce qui pourrait s'expliquer, compte tenu de l'histoire de cette population, par un faible nombre de géniteurs fondateurs. La structuration de la 4ème génération en plusieurs lots issus de parents différents apparaît comme la mesure de gestion minimale pour limiter la consanguinité au sein de cette population.

Résumé :  
Nineteen novel microsatellite loci were isolated from Adenomera andreae, a widespread Amazonian frog considered to be a species complex. Three multiplex kits were optimized. Genetic diversity was assessed in 66 individuals sampled in three populations along the West of the Approuague River catchment (French Guiana). We also tested the multiplex kits in four other Adenomera and nine Leptodactylus species with 43.4 and 17.5% success respectively.

Résumé : Twenty homologous microsatellite markers, or simple sequence repeats (SSRs), were developed for blackfin tuna (Thunnus atlanticus) through the use of a direct Seq-to-SSR approach. The number of alleles per locus ranged between 5 and 26, and the expected heterozygosity ranged between 0.640 and 0.969. Three loci displayed significant departure from Hardy-Weinberg equilibrium expectations, likely reflecting occurrence of null alleles. Another locus showed consecutive alleles that differed by one base pair only. Consequently, this locus may be prone to elevated rates of scoring errors. The remaining 16 loci will be valuable for studies in conservation genetics of blackfin tuna.

Résumé : In bird species that have a high movement capacity, dispersal may connect subpopulations over vast geographical regions, with important consequences for the design of conservation management strategies. Here we used a molecular approach to infer the patterns and rates of dispersal among eight Mediterranean subpopulations of the endangered Bonelli's Eagle, based on 245 individuals screened at 17 microsatellite loci. There was moderate genetic differentiation between subpopulations sampled in the western (Iberia and Morocco) and eastern (Cyprus) Mediterranean, whereas differentiation among subpopulations in the former region was weak to moderate and followed a pattern of isolation by distance. Within the western Mediterranean, the small, peripheral and ecologically unique population of southwest Portugal had the lowest genetic diversity and the highest differentiation. The remaining subpopulations formed two loose clusters, one including Morocco and southwest and eastern Spain, and the other northeast Portugal and western and central Spain. Few recent migrants were detected, and they originated primarily from adjacent subpopulations. Our findings suggest that western Mediterranean Bonelli's Eagles may have a large-scale metapopulation structure, with subpopulations connected to some extent by distance-dependent dispersal, probably influenced by natal philopatry and the geographical configuration of subpopulations. The combination of marked ecological and genetic divergence suggests that the peripheral subpopulation of southwest Portugal may be regarded as a distinct management unit.

Résumé : International audience
We isolated and characterized 16 polymorphic microsatellite loci for Lytocarpia brevirostris (Aglaophe- niidae), a hydrozoan common in the tropical Indo-Pacific region. Four to 34 alleles per locus were detected at the Indo-Pacific scale. At the population level, observed (Ho) and expected (He) heterozygosities ranged across 0.100–0.625 and 0.097–0.597, respectively. Three markers showed significant deviation from Hardy–Weinberg equi- librium, all of them presenting null alleles. Linkage dis- equilibrium was detected in three pairs of loci among 120. These primers provide powerful tools for studying popu- lation genetic diversity and the implication of life cycle strategies on population differentiation in tropical hydro- zoans. This will be valuable for the conservation of coral reefs biodiversity and the design of marine protected areas.

Résumé : Designing biodiversity conservation plans requires knowledge on the biogeographic distribution of taxabut also accurate estimates of species richness and diversification processes. However, measuring the phyleticrichness can be biased by the use of inappropriate taxonomical characters, leading to erroneous speciesdelimitation and diversity estimates.This work explores the phyletic richness at several taxonomic levels (generic, specific and intraspecific) ofthe hydrozoan family Aglaopheniidae (Marktanner-Turneretscher, 1890), with a particular focus on the South-Western Indian Ocean. Firstly, using several newly constructed phylogenies based on mitochondrial andnuclear markers, this study reveals that the phyletic diversity of this family is at underestimated by at least 50%:all studied genera are polyphyletic or with doubtful monophyletic status. Then, using several speciesdelimitation methods based on molecular markers, it sheds light on the richness of cryptic diversity of thisfamily, enlightening the potential of using an integrative taxonomic approach on these morphologically simpleorganisms. Finally, the population genetics of an Aglaopheniidae brooding species shows a high populationsstructuring with pervasive pattern of isolation by distance at several geographic scales (several to thousands ofkilometres), implying a potentially high cryptic diversity existing in this family.The results of this work provide new insights on Aglaopheniidae diversity, underlining the potentialinfluence of reproductive mode on the phyletic diversity and diversification processes of brooding hydrozoanbrooders. This thesis further highlights the relevance of using several complementary
La conservation et la gestion sur le long terme de la biodiversité nécessitent une connaissance de larépartition des taxons, mais également une estimation précise de leur diversité spécifique ainsi que desprocessus de spéciation ayant permis leur formation. Cependant, la mesure de la richesse phylétique peut êtrebiaisée par l’utilisation de caractères taxinomiques ne permettant pas de délimiter les espèces de manièreappropriée.Ce travail de thèse propose d’explorer la diversité phylétique à plusieurs niveaux taxinomiques(générique, spécifique et intra-spécifique) des Aglaopheniidae, une famille d’hydrozoaires, notamment présentedans le Sud-Ouest de l’océan Indien. Dans un premier temps, en utilisant des phylogénies basées sur plusieursmarqueurs (mitochondriaux et nucléaires), ce travail démontre que la diversité phylétique de cette famille est,au minimum, sous-estimée de moitié: tous les genres de la famille sont polyphyléthiques ou présentent un statutmonophylétique restant à confirmer. Dans un deuxième temps, l’utilisation de méthodes de délimitationd’espèces basées sur des données moléculaires met en évidence la diversité cryptique très élevée des morphoespècesétudiées, révélant l’intérêt potentiel des protocoles de taxinomie intégrative chez les organismesmorphologiquement simples. Enfin, l’étude de génétique des populations d’une espèce incubatriced’Aglaopheniidae révèle l’importance de la structuration des populations et de l’isolement par la distance chezcette espèce à plusieurs échelles géographiques (de quelques kilomètres à plusieurs milliers), impliquant unepotentielle diversité cryptique extrêmement élevée chez cette famille.L’ensemble des connaissances acquises lors de ce travail de thèse fournit un nouveau regard sur ladiversité de la famille des Aglaopheniidae, soulignant le potentiel impact du cycle de reproduction sur ladiversité phylétique et les processus de spéciation des hydrozoaires incubateurs. Cette thèse met en évidence lapertinence de l’utilisation de plusieurs procédures complémentaires de délimitation d’espèces pour étudier ladiversité des organismes morphologiquement simples.

Résumé : International audience
Measurements of branch xylem density, D_x, were made for 1466 trees representing 503 species, sampled from 80 sites across the Amazon basin. Measured values ranged from 240 kg m^?3 for a Brosimum parinarioides from Tapajos in West Pará, Brazil to 1130 kg m^?3 for an Aiouea sp. from Caxiuana, Central Pará, Brazil. Analysis of variance showed significant differences in average D_x across the sample plots as well as significant differences between families, genera and species. A partitioning of the total variance in the dataset showed that geographic location and plot accounted for 33% of the variation with species identity accounting for an additional 27%; the remaining "residual" 40% of the variance accounted for by tree to tree (within species) variation. Variations in plot means, were, however, hardly accountable at all by differences in species composition. Rather, it would seem that variations of xylem density at plot level must be explained by the effects of soils and/or climate. This conclusion is supported by the observation that the xylem density of the more widely distributed species varied systematically from plot to plot. Thus, as well as having a genetic component branch xylem density is a plastic trait that, for any given species, varies according to where the tree is growing and in a predictable manner. Exceptions to this general rule may be some pioneers belonging to Pourouma and Miconia and some species within the genera Brosimum, Rinorea and Trichillia which seem to be more constrained in terms of this plasticity than most species sampled as part of this study.

Résumé :  
Improvement of wood quality related traits is currently hampered by costly chemical and technological assays and the necessity to wait until the trees are nearly mature to evaluate wood properties. The availability of a vast quantity of genomic data opens now a new avenue to identify early selection criteria based on molecular information and therefore increase selection efficiency. Association mapping is becoming a method of choice to identify QTN (quantitative trait nucleotide) that contribute to complex trait variation. The implementation of this approach requires on the one hand knowledge of the molecular mechanisms underlying trait variation and polymorphism within candidate genes, and on the other hand the availability of phenotypically well characterized genetic material. We are developing this strategy in the frame of the French maritime pine breeding program, an economically important forest tree species in the South Western Europe. About 500 trees from the breeding population were evaluated for wood physical and chemical properties through the analysis of 2,800 half-sib progenies and 1,500 clones in 8 field tests. These same trees are being genotyped at 185 SNPs obtained from the sequencing of 41 candidate genes, and an additional set of 200 eSNPs detected in 147 EST-contigs (to be used as control). Statistical association between the breeding values of the 500 trees and their respective genotypes will be tested using mixed models accounting for relatedness among individuals of the breeding population.

Résumé : International audience
Vertebrate genomes contain around 20,000 protein-encoding genes, of which a large fraction is still not associated with specific functions. A major task in future genomics will thus be to assign physiological roles to all open reading frames revealed by genome sequencing. Here we show that C2orf62, a highly conserved protein with little homology to characterized proteins, is strongly expressed in testis in zebrafish and mammals, and in various types of ciliated cells during zebrafish development. By yeast two hybrid and GST pull-down, C2orf62 was shown to interact with TTC17, another uncharacterized protein. Depletion of either C2orf62 or TTC17 in human ciliated cells interferes with actin polymerization and reduces the number of primary cilia without changing their length. Zebrafish embryos injected with morpholinos against C2orf62 or TTC17, or with mRNA coding for the C2orf62 C-terminal part containing a RII dimerization/docking (R2D2) - like domain show morphological defects consistent with imperfect ciliogenesis. We provide here the first evidence for a C2orf62-TTC17 axis that would regulate actin polymerization and ciliogenesis.

Résumé : International audience
Semantic web standards, tools, ontologies and related technologies have considerably matured in the recent years. Nowadays, accessing a wide catalogue of biological, social, environmental, and ecological data sources helps stakeholders working on biodiversity to answer their complex questions. Will the real time access to web resources effectively support the definition of strategies to conserve and manage biodiversity? How might semantic web technologies help us to handle the complex and heterogeneous big data related to biodiversity? The workshop aims to identify the key challenges faced by the bioinformatics community, discuss potential solutions and identify the opportunities emerging from the trans-disciplinary interactions between Plant Science and Informatics experts. Therefore, we expect the bioinformatics experts to explain how they apply semantic web standards and tools to their scientific topic, from biology, agriculture, agro-ecology, genomics, environmental studies, to social sciences, citizen sciences. Research papers presenting various aspects of semantic web technologies applied to biodiversity data, ranging from position papers to implemented systems descriptions and their evaluation, will be selected. We are particularly interested in the use of the semantic technologies to design and develop systems that supports research on agricultural and wild biodiversity conservation and management for food security. Examples may include strategies for resilience to climate change pressures, sustainability of productive ecosystems, ecosystems services monitoring or territories management, rather than systems supporting only research on climate patterns or soil erosion.
