| organochlorinated contaminants in decapod crustaceans from the coasts of brittany and normandy (france). | the contamination and distribution of organochlorinated compounds were considered in three crustacean species (edible crab, cancer pagurus; spider crab, maja brachydactyla; velvet swimming crab, necora puber) from five sites along the coasts of brittany and normandy (western and north-western france). pcbs (16 single congeners), pp'-dde and hcb were measured in hepatopancreas, gonads and muscle: in all, 175 samples were analysed. the spider crab was the only species found in the five sampling si ... | 2007 | 17223177 |
| polychlorinated biphenyl contamination of the spider crab (maja brachydactyla): influence of physiological and ecological processes. | maja brachydactyla is a decapod crustacean widely distributed along the northeast atlantic coasts. the main objective of this work was to establish the influence of ontogenic factors, such as growth, aging, seasonal migrations, and reproduction, on the contamination of this species by polychlorinated biphenyls (pcbs). two populations were studied: one in the seine bay (eastern english channel), which is exposed to greatly contaminated discharges from the seine river, and one in the iroise sea (w ... | 2007 | 17373508 |
| photobacterium swingsii sp. nov., isolated from marine organisms. | six gram-negative coccobacilli were isolated from pacific oysters (crassostrea gigas) from mexico and haemolymph of spider crabs (maja brachydactyla) from spain. all of the isolates grew as small green colonies on thiosulphate-citrate-bile salts-sucrose (tcbs) agar and were facultatively anaerobic, oxidase-positive and sensitive to the vibriostatic agent o/129. repetitive palindromic pcr analysis revealed a high degree of genomic homogeneity among the isolates. several phenotypic traits differen ... | 2011 | 20228205 |
| diversity of vibrios in the haemolymph of the spider crab maja brachydactyla. | the aim of this study was to characterise and identify vibrios isolated from the haemolymph of apparently healthy adult spider crabs (maja brachydactyla) wild-caught in the spanish localities of galician coast and in the canary islands and also from captive animals held at irta's facilities in the ebro delta of catalonia, north-west spanish mediterranean coast. | 2010 | 20374412 |
| commercially important species associated with horse mussel (modiolus modiolus) biogenic reefs: a priority habitat for nature conservation and fisheries benefits. | horse mussel reefs (modiolus modiolus) are biodiversity hotspots afforded protection by marine protected areas (mpas) in the ne atlantic. in this study, horse mussel reefs, cobble habitats and sandy habitats were assessed using underwater visual census and drop-down video techniques in three uk regions. megafauna were enumerated, differences in community composition and individual species abundances were analysed. samples of conspicuous megafauna were also collected from horse mussel reefs in or ... | 2017 | 28222862 |
| photobacterium sanguinicancri sp. nov. isolated from marine animals. | six strains were isolated from the hemolymph of the spider crab maja brachydactyla, captured in spain, and one from a diseased blue mussel, mytilus edulis. the 16s rrna gene sequences showed close similarity to the recently described photobacterium swingsii (98.1 %) and to a lesser degree to photobacterium aquimaris (97.8 %). mlsa analyses showed a monophyletic group including p. swingsii that form a new subclade. all genomic analyses (average nucleotide identity, average amino acid identity, an ... | 2016 | 27048242 |
| elasmopus thalyae sp. nov. (crustacea: amphipoda: maeridae), a new benthic species from soft and hard bottoms of arcachon bay (se bay of biscay). | a new species of elasmopus is described and figured from specimens collected in different benthic communities of arcachon bay. it can be distinguished from its closest relative e. rapax by the palmar ornamentation of male gnathopod 2 propodus (shelf and 2 teeth). it preferentially lives on hard bottoms (in mussel fouling of navigation buoys, sabellaria spinulosa reefs, algal rocky bottoms, laminaria and saccorhiza bulbs and as epibiont on the carapace of maja brachydactyla) but also less abundan ... | 2015 | 25661024 |
