“…[36] noticed that gills were the only organ to exhibit a continued increase in the gills of clam tissue Cu concentration with the corresponding increase of Cu in the seawater. Cu concentrations were significantly high in the gills confirming that it is the main organ for metal bioaccumulation in Bathymodiolus azoricus (mussels) is the gills [3]. [37] and [38] reported that, Cu in the gills of Bathymodiolus azoricus and Cu in the gills of mussels from reference sites was higher when compared with similar tissues of coastal mussels, Mytilus edulis and Mytilus galloprovincialis from heavily polluted environments.…”

“…It has been reported that in the uncontaminated conditions the hepatopancreas demonstrates the highest values of toxic metals as a result of its major role in the uptake of metals from food [36]. The major environmental problem in the coastal area is directly related to the impact of domestic effluents [3]. The average concentrations of Cu and Cd in all dissected organs-mantle, gills and digestive gland-of Lithophaga lithophaga in the present study were lower than that reported by [17] 7800 µg/g for soft tissues of shellfish.…”

“…They have been studied in hydrothermal vent mussels from the Mid-Atlantic Ridge and East Pacific Rise (Hardivillier et al, 2004;Bebbiano et al, 2005;Hardivillier et al, 2006). Antioxidant enzyme activity is of particular interest at vents due to the enriched metal concentration within the hydrothermal fluids, and has been examined in a range of invertebrates, including Alvinellid polychaetes, mussels and shrimp (Bebbiano et al, 2005;Marie et al, 2006;Company et al, 2006;Gonzalez-Rey et al, 2007;Shin et al, 2009).…”

A study of the ecology of fish endemic to hydrothermal vents on the East Pacific Rise was undertaken utilizing a variety of techniques, focusing on the bythitid Thermichthys hollisi. Stable isotope and gut content analyses were used to elucidate prey choice and trophic relationships. Otolith chemical signatures were investigated to determine whether this technique could be utilized to examine life history strategy and habitat use. Chemical characteristics of preferred fish habitat and gene expression responses habitat chemistry were explored. Gut contents indicated that T. hollisi specimens were actively feeding upon a combination of brachyuran crabs, Alvinocaris shrimp, polychaetes, and zoarcid fish with the majority of fish containing evidence of crustacean prey. Carbon, nitrogen, and sulfur stable isotopic measurements support a chemosynthetically based prey source and place T. hollisi in the uppermost trophic levels of vent communities. The influence of exposure to hydrothermal fluids was apparent in otoliths from both species of vent fish, most noticeably within the relatively elevated Sr:Ca and depleted Mg:Ca ratios. Otolith chemistry suggested that the zoarcid Thermarces cerberus experiences greater direct exposure to diffuse fluids than does T. hollisi, which is concurrent with apparent habitat preferences. Isotopic patterns across the span of the otolith suggested that T. cerberus spends its entire life within the vent system. In contrast, it appeared that T. hollisi exists outside of the influence of hydrothermal activity for some early portion of its life-cycle. Time-lapse photography and in situ electrochemistry indicated that T. hollisi are preferentially utilizing fish holes where there are elevated temperatures and sulfide levels, and variable oxygen levels in comparison to ambient bottom water. A fragment of Cu, Zn superoxide dismutase was successfully amplified from T. hollisi mRNA, but there were no differences in expression levels between tissue types or among individuals within the small sample examined. In general, it appears that T. hollisi is both influenced by and may exert a greater influence on hydrothermal vent communities to a greater degree than initially hypothesized.Thesis Supervisor: Timothy M.

The early life stages of freshwater mussels are particularly sensitive to copper (Cu) contamination. We measured the acute toxicity, bioaccumulation, and sublethal effects of Cu in glochidia. In addition, we used radiolabeled Cu ( Cu) to examine the time-dependent kinetics of uptake over 24 h. Uptake of Cu by live and dead glochidia exposed to 0.11 μmol/L exhibited similar hyperbolic patterns over the first 40 min, indicating an adsorptive phase independent of larval metabolism. Thereafter, uptake was linear with time, with a 10-fold lower bioaccumulation rate in live than in dead animals, representing a close to steady state of Cu regulation. In contrast, dead glochidia exhibited a progressively increasing uptake, possibly attributable to the fact that metal-binding sites become more accessible. Mortality was strongly correlated with bioaccumulation (48 h); live glochidia exposed to Cu concentrations>0.27 μmol/L lost their regulatory ability and accumulated Cu to an even greater extent than dead animals. Exposure to Cu induced significant decreases in whole-body Na and Mg concentrations; increases in reactive oxygen species concentration, lipid peroxidation, and protein carbonylation; and a decrease in antioxidant capacity against peroxyl radicals. Overall, these results clarify the patterns of Cu uptake and regulation, emphasize the importance of distinguishing between live and dead larvae, and indicate that toxicity is associated with Cu bioaccumulation, involving both ionoregulatory disturbance and oxidative stress.
