Molecular analyses of bacteria associated with photosynthetic organisms are often confounded by coamplification of the chloroplastidial 16S rDNA with the targeted bacterial 16S rDNA. This major problem has hampered progress in the characterization of bacterial communities associated to...Contributeur (s):

Massa, Sonia I. / Paulino, Cristina M. / Serrao, Ester A. / Duarte, Carlos M. / Arnaud-haond, Sophie - 2013Background: The relationship between species diversity and components of ecosystem stability has been extensively studied, whilst the influence of the genetic component of biodiversity remains poorly understood. Here we manipulated both genotypic and allelic richness of the seagrass Zostera noltii...Contributeur (s):

Boavida, Joana / Paulo, Diogo / Aurelle, Didier / Arnaud-haond, Sophie / Marschal, Christian / Reed, John / Goncalves, Jorge M. S. / Serrao, Ester A. - 2016Background The highly valuable red coral Corallium rubrum is listed in several Mediterranean Conventions for species protection and management since the 1980s. Yet, the lack of data about its Atlantic distribution has hindered its protection there. This culminated in the recent discovery of...Contributeur (s):

Teixeira, Sara / Serrao, Ester A. / Arnaud, Sophie - 2012Dispersal plays a fundamental role in the evolution and persistence of species, and especially for species inhabiting extreme, ephemeral and highly fragmented habitats as hydrothermal vents. The Mid-Atlantic Ridge endemic shrimp species Rimicaris exoculata was studied using microsatellite markers...Contributeur (s):

Biological invasions rank amongst the most deleterious components of global change inducing alterations from genes to ecosystems. The genetic characteristics of introduced pools of individuals greatly influence the capacity of introduced species to establish and expand. The recently demonstrated...Contributeur (s):

Teixeira, Sara / Olu, Karine / Decker, Carole / Cunha, Regina L. / Fuchs, Sandra / Hourdez, Stephane / Serrao, Ester A. / Arnaud-haond, Sophie - 2013Chemosynthetic ecosystems are distributed worldwide in fragmented habitats harbouring seemingly highly specialized communities. Yet, shared taxa have been reported from highly distant chemosynthetic communities. These habitats are distributed in distinct biogeographical regions, one of these being...Contributeur (s):

Arnaud-haond, Sophie / Candeias, Rui / Serrao, Ester A. / Teixeira, Sara - 2013Polymorphic microsatellites were developed for the invasive green algae Caulerpa taxifolia using next generation DNA sequencing. Results showed a limited rate of microsatellites for the amount of sequences, possibly explaining failure of previous attempts for microsatellite development through...Contributeur (s):

Teixeira, Sara / Cambon-bonavita, Marie-anne / Serrao, Ester A. / Desbruyeres, Daniel / Arnaud-haond, Sophie - 2011Aim Deep-sea hydrothermal vents are unstable habitats that are both spatially and temporally fragmented. In vent species, a 'short-term insurance' hypothesis would lead us to expect mostly self-recruitment, limiting the loss of larvae in the deep ocean or water column and increasing...Contributeur (s):

Background: Hybridization or divergence between sympatric sister species provides a natural laboratory to study speciation processes. The shared polymorphism in sister species may either be ancestral or derive from hybridization, and the accuracy of analytic methods used thus far to derive...Contributeur (s):

Ruela Boavida, Joana / Assis, Jorge / Silva, Inga / Serrao, Ester A. - 2016Factors shaping the distribution of mesophotic octocorals (30-200 m depth) remain poorly understood, potentially leaving overlooked coral areas, particularly near their bathymetric and geographic distributional limits. Yet, detailed knowledge about habitat requirements is crucial for conservation...Contributeur (s):

Arnaud-haond, Sophie / Moalic, Yann / Hernandez-garcia, Emilio / Eguiluz, Victor M. / Alberto, Filipe / Serrao, Ester A. / Duarte, Carlos M. - 2014The recurrent lack of isolation by distance reported at regional scale in seagrass species was recently suggested to stem from stochastic events of large-scale dispersal. We explored the usefulness of phylogenetic information contained in microsatellite loci to test this hypothesis by using the...Contributeur (s):

Arnaud-haond, Sophie / Duarte, Carlos M. / Diaz-almela, Elena / Marba, Nuria / Sintes, Tomas / Serrao, Ester A. - 2012The maximum size and age that clonal organisms can reach remains poorly known, although we do know that the largest natural clones can extend over hundreds or thousands of metres and potentially live for centuries. We made a review of findings to date, which reveal that the maximum clone age and...Contributeur (s):

Massa, Sonia I. / Pearson, Gareth A. / Aires, Tania / Kube, Michael / Olsen, Jeanine L. / Reinhardt, Richard / Serrao, Ester A. / Arnaud-haond, Sophie - 2011Predicted global climate change threatens the distributional ranges of species worldwide. We identified genes expressed in the intertidal seagrass Zostera midi during recovery from a simulated low tide heat-shock exposure. Five Expressed Sequence Tag (EST) libraries were compared, corresponding to...Contributeur (s):

Arnaud-haond, Sophie / Duarte, Carlos M. / Teixeira, Sara / Massa, Sonia Isabel / Terrados, Jorge / Nguyen Hong, Tri / Phan Nguyen, Hong / Serrao, Ester A. - 2009The widespread use of Agent Orange (a mixture of phenoxyl herbicides) over Southern Vietnam by US Forces led to the decimation of mangrove forests in the Mekong Delta. Mangrove trees Avicennia alba were sampled across the Mekong Delta; their age was assessed using models based on internode growth...Contributeur (s):

Arnaud-haond, Sophie / Marba, Nuria / Diaz-almela, Elena / Serrao, Ester A. / Duarte, Carlos M. - 2010The diversity-stability relationship is the subject of a long-standing debate in ecology, but the genetic component of diversity has seldom been explored. In this study, we analyzed the interplay between genetic diversity and demographic responses to environmental pressures. This analysis included...Contributeur (s):
