Characterization of polymorphic microsatellite loci in the Antarctic krill Euph...
Candeias, R.; Teixeira, Sara; Duarte, C. M.; Pearson, G. A.Background: The Antarctic krill, Euphausia superba is a pelagic crustacean, abundant in high-density swarms (10 000 – 30 000 ind/m2) with a circumpolar distribution and a key role in the food web of the Southern Ocean. Only three EST derived microsatellite markers have been used in previous genetic studies, hence we developed additional highly polymorphic microsatellite markers to allow robust studies of the ge...
Entangled effects of allelic and clonal (genotypic) richness in the resistance ...
Massa, S. I.; Paulino, Cristina M.; Serrão, Ester; Duarte, C. M.; Arnaud-Haond, S.Background - 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, in order to explore their respective influences on the resistance of the experimental population to stress. Thus ...
Invasion is a community affair: clandestine followers in the bacterial communit...
Aires, T.; Serrão, Ester; Kendrick, G.; Duarte, C. M.; Arnaud-Haond, 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 heritability of microbial communities associated to individual genotypes of primary producers makes them a potentiall...
Implications of extreme life span in clonal organisms: millenary clones in mead...
Arnaud-Haond, S.; Duarte, C. M.; Diaz-Almela, E.; Marbà, N.; Sintes, T.; Serrão, EsterThe 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 size estimates reported in the literature are typically limited by the scale of sampling, and may grossly underestima...
Evaluation of cardiovascular protective effect of different apple varieties - C...
Serra, A. T.; Rocha, J.; Sepodes, B.; Matias, A. A.; Feliciano, R. P.; Carvalho, A. d.; Bronze, M. R.; Duarte, C. M. M.; Figueira, M. E."Epidemiological evidence supports the concept that diets rich in fruits and vegetables promote health and attenuate or delay the onset of cardiovascular disease (CVD). In particular, a reduced risk of CVD has been associated with apple consumption, probably due to the cholesterol-lowering effect of the main bioactive compounds, namely fiber and polyphenols. In this work, the effect of diet supplementation with...
Genetic recolonization of mangrove: Genetic diversity still increasing in the M...
Arnaud-Haond, S.; Duarte, C. M.; Teixeira, S.; Massa, S. I.; Terrados, J.; Tri, N. H.; Hong, P. N.; Serrão, EsterThe 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 and samples were genotyped for 6 microsatellite loci. The evolution of genetic diversity over time elapsed since loc...
Solubility of dense CO2 in two biocompatible acrylate copolymers
Duarte,A. R. C.; Sousa,A. R. Sampaio de; Sousa,H. C. de; Gil,M. H.M.; Jespersen,H. T.; Duarte,C. M.M.Biocompatible polymers and copolymers are frequently being used as part of controlled delivery systems. These systems can be prepared using a "clean and environment friendly" technology like supercritical fluids. One great advantage of this process is that compressed carbon dioxide has excellent plasticizing properties and can swell most biocompatible polymeric matrixes, thus promoting drug impregnation process...
Genetic diversity of a clonal angiosperm near its range limit: The case of Cymo...
Alberto, F.; Arnaud-Haond, S.; Duarte, C. M.; Serrão, EsterThe seagrass Cymodocea nodosa forms a unique community in the Canary Islands, where it is classified as an endangered species. Biogeographic theory predicts that clonal species on islands near their distributional limits might show lower proportions of sexual (versus clonal) reproduction, lower genetic diversity, and higher differentiation. We addressed these hypotheses by comparing the genetic structure of C. ...
