The effects of Didemnum vexillum overgrowth on Mytilus edulis biology and ecology
… organisms, such as the common blue mussel Mytilus edulis. Preliminary observations and short-term studies showed potential effects of epibiosis on M. edulis growth, specifically lip thickness and tissue index. This dissertation study further examined the effects of D. vexillum on growth and …

Uptake and depuration of cyanotoxins in the common blue mussel Mytilus edulis.
… of cyanotoxins in the common blue mussel Mytilus edulis, three feeding trials were performed. During these, mussels were exposed to two cyanobacteria strains - Nodularia spumigena KAC66 and Microcystis aeruginosa PCC 7813 - both individually and simultaneously. A rapid dose-dependent …

Supercritical fluid extraction of polychlorinated biphenyls and organochlorine pesticides from mussel tissue (Mytilus edulis)
The supercritical fluid extraction (SFE) of twenty one polychlorinated biphenyls (PCBs) and eight organochlorine pesticides (OCPs) from freeze dried mussel tissue is discussed, demonstrated, and compared to traditional Soxhlet extractions. The aim of this study was to determine the efficacy of SFE …

Toxic effects of aromatic hydrocarbon mixtures isolated from crude oils to blue mussels (Mytilus edulis)
… from four different crude oils. The blue mussel (Mytilus edulis) biotest used shows a reduction of mussel feeding activity after 24 h exposure with increasing aqueous and tissue concentrations. The fractions of total and monoaromatic hydrocarbons exert similarly strong toxic effects as evidenced …

Aspectos tecnológicos y bio-ecológicos del asentamiento de mejillón, Mytilus edulis platensis, sobre colectores artificiales
El cultivo de mejillón en la Argentina es un recurso de alta potencialidad productiva y económica. Una de las principales limitantes para la expansión de esta actividad se encuentra en la provisión de juveniles para la cría y engorde, comúnmente denominados “semilla”. En el golfo San Jorge, Chubut, …

Characterization of the major extrapallial fluid protein of the mollusc, Mytilus edulis: Implications for function
… of the extrapallial (EP) fluid of the mollusc Mytilus edulis, named the EP protein, has been previously isolated and partially characterized. It has been proposed to play an important role in shell mineralization because of its intriguing property of Ca2+ -binding induced …

Proteomic approaches to environmental stress in mussel Mytilus edulis due to emerging classes of anthropogenic pollutants
… changes in sentinel species such as the mussel, Mytilus edulis. This thesis aimed to compare the potential of traditional biomarkers (such as enzyme activity measurement) and newer redox proteomic approaches. Environmental proteomics, especially a redox proteomics toolbox, may be a novel way to …

The maintenance, evolution, and impacts of inducible morphological defenses in Mytilus edulis: Responses to multiple and invasive predators
… explored induced defenses in the marine mussel Mytilus edulis as they are affected by (a) shared evolutionary history with invasive crab predators, (b) specificity of responses to multiple predators (singly and combined) with different foraging strategies, and (c) spatial and temporal variation …

The effects of biotic and abiotic factors on byssogenesis, growth and movement patterns of the blue mussel, Mytilus edulis
… byssogenesis and growth of the blue mussel, Mytilus edulis, affected by wave exposure, temperature, and epibiont fouling. Byssogenesis and movement abilities of two size classes of mussels were also quantified in relation to epibiont fouling and predator presence. Results from a series of …

Untersuchungen zum Vorkommen und zur Mengenverteilung polarer Biomarker in Algen, Muschelbiodepositen und Oberflächensedimenten im Einflußbereich einer intertidalen Muschelbank (Mytilus edulis)
… (Biomarker) zeigten, daß die Muschel Mytilus edulis nicht nur die Menge sondern auch die Zusammensetzung des organischen Materials im Wattenmeer beeinflußt. Muschelbänke sind ebenfalls Senken für sedimentierende Makroalgen. Ein weiteres wichtiges Ergebnis dieser Arbeit ist, daß die …

Évaluation des concentrations en métaux lourds dans les moules bleues (mytilus edulis) et les produits halieutiques de la Baie des Chaleurs
… la région. En 2006 et 2008, des moules bleues (Mytilus edulis) ont été échantillonnées dans des sites situés le long de la côte de la baie des Chaleurs au Nouveau-Brunswick afin d'établir une distribution spatio-temporelle des métaux lourds. Les moules de Belledune contiennent jusqu'à quatre …

X-ray diffraction studies of muscle : observations on the anterior byssus retractor muscle of Mytilus edulis and the insect flight muscle from Sarcophaga bullata
… of the anterior byssus retractor muscle from Mytilus edulis was studied as the muscle was extended. It was found that variations in this spacing were very small and consistent with the hypothesis that the interfilament spacing was independent of the extension of the muscle. It was observed …

Ecotoxicology of marine biotoxins in bivalve shellfish
… were investigated on three shellfish species: Mytilus edulis, Ruditapes philippinarum and Crassostrea gigas. Histological examination of the gill, mantle and hepatopancreas tissues revealed varying intensity of damage depending both on the tissue type and the species involved. At the cellular …

Design and Characterization of Biomimetic Adhesive Materials
… often in the form of proteins. The blue mussel Mytilus edulis and sandcastle worm Phragmatopoma californica produce adhesive proteins that help them to adhere in wet, turbulent environments. The frog Notaden bennetti secretes a sticky, proteinaceous emulsion that helps it defend against …

A Mechanistic-Based Approach to Reduce Biological Adhesion
… insights suggest that the marine mussel, Mytilus edulis, adheres with proteins that undergo oxidative cross-linking. Our work has focused on taking a mechanistic approach to defeat adhesion with the incorporation of reducing agents into a variety of coatings to inhibit oxidative chemistry …

Biotic and abiotic factors influencing the invasion success and ecological impacts of the Pacific oyster, Crassostrea gigas
… invasions onto beds of the native blue mussel, Mytilus edulis, have seen shifts in dominance from mussels to oysters. Although invasions of C. gigas have been investigated, the influence of water motion on its invasion success and interactions with native M. edulis is almost unknown. Thus here, …
