“…The availability of the Mn 2+ ion may be influenced by microbial action or through input of high Mn sediments to the marine system (Klinkhammer & McManus 2001, Husmann et al 2012. Shells collected from Waipu were found to have the lowest Mn:Ca ratios.…”

Trace elemental fingerprinting has been used to estimate population connectivity of marine species by using variations in the chemistry of shell produced in different water masses to determine the natal location of settlers. This method has been successfully used to differentiate between estuaries and coasts at spatial scales of 10s to 100s of km. Here, we investigated the suitability of trace elemental fingerprinting to distinguish subpopulation connectivity at management scales suitable for local fishery or conservation management. The trace element chemistry of Austrovenus stutchburyi shells was used to distinguish between intra-and inter-estuary subpopulations at local (~1 to 10 km) scales, with ~99% success. Differences between 8 locations within a large harbour and 4 smaller neighbouring estuaries were detected. Sr:Ca, Zn:Ca and Mn:Ca elemental ratios were the primary drivers of inter-site trace elemental fingerprint differences. Intra-shell variation in elemental fingerprints was used to examine temporal stability and demonstrated that, although intra-shell differences were present, site-specific differences in elemental fingerprints were maintained. The results of this study suggest trace elemental fingerprinting can be a viable method to estimate population connectivity over small inter-and intra-estuary spatial scales.

“…This would, however, be important to understand environmental impact, including sources of contamination in marine bivalve populations, and also the biogeochemical processes that render environmental metals/contaminants as ''bioavailable''. Tissue specific Fe-contents in the circum-Antarctic clam Laternula elliptica (King and Broderip, 1832) vary considerably between sampling sites around the Antarctic continent (Ahn et al, 1996;Nigro et al, 1997;Lohan et al, 2001;Deheyn et al, 2005;Curtosi et al, 2010;Husmann et al, 2012;Poigner et al, 2013b). Highest contents were found at Deception Island where hydrothermal waters release high loads of dissolved Fe into the environment (Rey et al, 1995;Deheyn et al, 2005).…”

“…Several authors assumed lithogenic sediment particles derived by sedimentation of glacigenous debris to be the source for high Fe tissue contents in the Antarctic clam (e.g. Abele et al, 2008;Curtosi et al, 2010;Husmann et al, 2012). Alternatively, Poigner et al (2013b) propose bioavailable Fe (oxyhydr)oxides, in particular ferrihydrite that precipitates from sediment pore water Fe 2+ , as predominant…”

“…L. elliptica also expresses the Fe storage protein ferritin in several tissues (digestive gland, gill, foot) as well as in hemocyte cells in large quantities (Husmann, 2013). On average 30% of total Fe within the hemolymph 1 are bound in hemocyte cells (Poigner et al, 2013b) and digestive gland and gills show higher Fe contents (Husmann et al, 2012;Poigner et al, 2013a) compared to tissues of lower ferritin expression (e.g., siphon, mantle; liver was not investigated; Husmann et al, 2012;Husmann, 2013;Poigner et al, 2013a). Nevertheless, the Fe turnover is considerably faster in L. elliptica compared to humans, since Poigner et al (2013b) (Henkel et al, 2013;Monien et al, 2013), and (iii) the conformity of averaged d 56 Fe values in bivalves hemolymph (À1.1‰) and the reactive Fe fraction in surface sediments (À0.25 ± 0.12‰ and À0.56 ± 0.10‰; S. Henkel, unpublished data) to the preferred assimilation of lighter isotopes along the food chain.…”

This study was conducted to find out the changes of survivorship, respiration and organ structure of Mactra veneriformis exposed to copper (Cu). Experimental period was four weeks. Experimental groups were composed of one control condition and three copper exposure conditions (0.025, 0.050 and 0.100 mg/L). The results of the study confirmed that copper induces reduction of survival rate and respiration rate and histopathology of organ structure of the bivalve. In the copper concentration of 0.100 mg/L, mortality was 100% after Cu exposure of 3 weeks. Respiration rate was observed exposure groups lower than control decline by 75%. Histological analysis of organ system illustrated expansion of hemolymph sinus, disappearance of epidermal layer and degeneration of connective tissue layer of the mantle. Also, histological degenerations as epithelial necrosis and hyperplasia of mucous cells are recognized in the gill and it was observed expansion of hemolymph sinus, disruption of epithelial layer, decrease of mucous cell and degeneration of connective tissue layer in the foot. In the digestive diverticulum, it was showed atrophy of basophilic cell and degeneration of epithelial cell in the digestive tubules, and as the concentration of copper increased the accumulation of lipofuscin increased.
