The aim of this study was to evaluate the effect of diesel exposure on the antioxidant defense in the digestive gland of the gastropod Nacella concinna, and the possibility of using these responses as biomarkers of diesel exposure. The activity of the antioxidant defense enzymes glutathione S-transferase, glutathione reductase, superoxide dismutase and catalase, as well as lipid peroxidation and protein carbonylation, as oxidative damage markers, were determined. Among the enzymes analyzed, exposure to diesel significantly modulated only the levels of glutathione S-transferase. Although the oxidative damage marker lipid peroxidation increased in the animals exposed to diesel, protein carbonylation levels remained unchanged. The results suggest that the responses of the antioxidant defense in the digestive gland of the gastropod N. concinna may not be as good biomarkers of diesel exposure as expected.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127107112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On board censuses were conducted to evaluate the abundance and distribution of seabirds. e most abundant species was the Atlantic yellow-nosed albatross alassarche chlororhynchos, with 51 individuals and the least species abundant was the Blackbellied Storm Petrel Fregetta tropica, with only two individuals. Latitude 29° S showed the largest abundance of seabirds (n=41), whereas the smallest abundance was observed at latitude 24o S (n=2). e highest richness was observed at latitudes 26° S and 30o S (n=5 in each degree).

Microphytobenthos can be equally important to eponthic microbiota, or even hold the bulk of primary production in periods a er the ice melting in late spring. Among the various groups forming the benthic community, diatoms are the most important photoautotrophs regarding diversity as well as the biomass available to the consumers. In this report we present a taxonomic survey of diatoms belonging to the Class Bacillariophyceae found in the plankton of Admiralty Bay, from samples collected between 2002 and 2010 in every December and February. A total of 53 species was recorded. e majority of the diatoms have benthic habit, usually associated to ice or rocks and macroalgae, indicating the in uence of bottom communities over the superjacent plankton. ose species were recorded in the water column possibly due to the local hydrographic dynamics, which might resuspend cells from microphytobenthos. Regarding taxonomy, about 25 species are newly reported to Admiralty Bay, and several identi cation and nomenclatural problems were found. We recommend that the ongoing monitoring program in the region includes sampling of the benthic community looking for di erent substrates like ice, rocks and macroalgae, also aiming to determine the origin of benthic diatoms found in the plankton of Admiralty Bay.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128866197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Opportunistic samples of Antarctic terns (Sterna vittata), Snowy Sheatbill (Chionis alba) and Blueeyed Shag (Phalacrocorax atriceps) were also analyzed. Hexachlorobenzene (HCB), selected chlordane-related compounds, dieldrin, mirex and p,p’-DDE were the chlorinated pesticides encountered at the highest levels in all samples. On average, concentrations of chlorinated pesticides were significantly higher in skuas than in any of the other species of birds. For example, concentrations of oxychlordane, dieldrin, mirex and p,p’DDE in skuas were a factor of approximately 15, 10, 25, and 30 times higher in skuas than in penguins, respectively. Similarly, the average total concentration of PCBs was about 70 times higher in skuas than in penguins. In contrast, the concentrations of HCB were comparable in both species of birds. The much higher concentrations of POPs encountered in the blubber of skuas compared to the other species of birds included in this study can be attributed to its position in the food web as they eat fish, krill, other birds and carcasses. Total PAH contents were similar in all birds with a predominance of compounds with low molecular weight (e.g., naphthalene, 1-methylnaphthalene and 2-methylnaphthalene). The ingestion either from food or during preening is considered to be the primary source of PAHs for birds. Although PAHs are well metabolized by birds and readily excreted, they can be detected in fat depots a short period after the uptake. The detection of POPs in Antarctica wildlife, particularly those species with the greatest fidelity to the Antarctic continent (i.e., penguins) is an evidence of global dispersion of these compounds.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127777843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
