A total of 34 pellets of Imperial Shag were analyzed and their frequency of occurrence was calculated. Fish remains were found in all pellets. Two families of demersal-benthic sh were identi ed through otoliths: Harpagiferidae and Nototheniidae. Nematodes occurred frequently. Other invertebrates such as molluscs and polychaetes occurred occasionally, so as vegetable matter (algae) and stones. ese items are probably from stomach contents of ingested sh or were accidentally ingested by the bird while building the nest. Our preliminary analysis showed that Imperial Shags breeding on Elephant Island have a similar diet composition to other shag species which breed in the sub-Antarctic islands and in the Antarctic Peninsula, with some items absent. However, further analysis will present more concrete data on the mass, volume and taxonomic species level of each item.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"25 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":"125578871","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}

Cetacean distribution data were obtained during ship-based surveys run by the Brazilian Antarctic Program from 1998 to 2011 austral summers. Line transect sampling methods were used to calculate cetacean encounter rates. e diversity index for each area was determined by the Shannon-Weaver diversity index. Humpback, minke and killer whales were the most frequently sighted species, predominating in areas with low species richness such as Gerlache Strait. Areas without species dominance (e.g. Elephant Island and Weddell Sea) showed greater diversity. Our results suggest that open areas and areas close to oceanographic fronts sustain lower encounter rates for individual species but support greater diversity than con ned areas.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"36 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":"126905476","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}

Based on microscopic analysis, phytoplankton taxonomic composition and biomass are investigated since 2009. This report presents results from the 2009/2010 and 2010/2011 summer surveys regarding the phytoplankton size-structure and biomass. Four scenarios were proposed in our study for environmental conditions and phytoplankton community: 1) 2009/2010 Early Summer; diatom growth was promoted by high Si:N, but inhibited by low N:P and low temperature, 2) 2009/2010 Late Summer; diatom growth was inhibited by low N:P and low Si:N, and high temperature and low N:P promoted dinoflagellates growth, due to their low optimum N:P ratios compared to diatoms; 3) 2010/2011 Early Summer; diatom growth was promoted by high N:P, high Si:N and high temperature and 4) 2010/2011 Late Summer; blooms of chain-forming diatoms (e.g. Thalassiosira spp.), favoured by high Si:N and high temperature, and it could explain the drastic reduction both in nitrate and silicate. The microplankton community of Admiralty Bay presented a high variability during the studied period that was clearly dictated by environmental factors. The time window covered by this study gives us only a glimpse of the direction of long term changes that the Antarctic environment might be experiencing. A more complete picture of such trends relies heavily on the continuity of the long-term monitoring program.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"175 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":"132219157","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}

Samples of the four genus types of Harpacticoida Copepod were found in a macroalgae (Himantothallus grandifolius) especially in its appressoria, collected in the melt water area of Admiralty Bay, King George Island, Archipelago, South Shetlands, Antarctica: Stygonitocrella (Ameiridae Family), Porcellidium (Porcellidiidae Family), Alteutha potter (Peltidiidae Family), Tisbisoma (Paramesochridae Family). e copepods found in this study possess adaptation qualities that may facilitate the exploration of macroalgae, such as: epibenthic body format, which allows greater swimming capacity or a dorso-ventrally attened body, with prehensile rst pair of legs or with a large maxilliped subchelate, the latter being adaptations to be able to x itself to thalloid surfaces, in locations with strong water currents. e genus Porcellidium and the Paramesochridae Family are frequently found associated to macroalgae. Alteutha potter is described in literature as planktonic. However, we suggest that the specie can be benthonic and is capable of migrating to zooplankton. Stygonitocrellaé is described as a species of continental and subterranean waters. e fact that algae have been found at just 15m depth with strong water melt current can help explain its presence. e identi cations continue underway and include analysis of phytal samples of other macroalgae collected in the Admiralty Bay from 2010 to 2011.","PeriodicalId":169975,"journal":{"name":"INCT-APA Annual Activity Report","volume":"11 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132241451","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}
