| Abstract: The objective of this work was to verify the existence of bioaccumulation in mussels of the species Perna perna, by determining the concentration of metal trace elements, in Urubuqueçaba Island, Santos Bay, Santos, SP, Brazil. Mussels were collected in natural banks and rocky shores, and sampling took place from April 2010 to June 2011. The concentration of the trace metal elements - aluminum, cadmium, cromium, copper, iron, manganese, nickel, lead, and zinc - was determined according to mussel sex, length, and seasonality classes, in a flame atomic absorption spectrometer. Statistical analyses were applied to the results with the use of the software PAST, with parametric and nonparametric approaches, at 5% probability. In the summer, mussels... |

| The objective of this work was to evaluate the total and thermotolerant coliform densities in the oyster culture water of Cananeia, SP, Brazil, correlating these densities with environmental variables and tidal variations. Superficial water samples were collected in two tide conditions (spring and neap) from three areas of Cananéia municipality (Mandira, Itapitangui and Cooperostra). The three studied areas showed good conditions for the culture regarding coliform densities. The two tidal conditions differed significantly as to total coliform concentration; however, the same procedure was not performed for thermotolerant coliforms. No correlation was observed between water temperature, pH, and concentrations of total and thermotolerant coliforms. Coliform... |

| Cabot's Terns Thalasseus acuflavidus (Latham, 1737) are widely distributed along the Atlantic coast of South America from the Caribbean Islands (12º S) to the region of Porto Deseado, Argentina (46º S). Daily observations were conducted on the Cardos Island during 2003, 2005 and 2006 to determine timing and nesting success, and the reproductive biology of the Cabot's Terns nesting there. The first adults arrived at the colony from 22 April to 15 May during the three years recorded; a total of 144 nests were recorded in 2003, 174 in 2005 and 50 in 2006. Observed incubation time was 24.1 ± 0.35 days, and mean egg size was 5.15 ± 0.02 cm in length and 34.30 ± 0.25 g in weight. Hatching success was lowest in 2003 and highest in 2006, with natural causes (such... |

| O objetivo deste trabalho foi avaliar a variação sazonal e abundância do Talha-mar Rynchops niger no estuário de Cananéia-Iguape-Ilha Comprida. Durante o período de janeiro a dezembro de 2005. Foram realizados censos semanais, com auxílio de binóculos em cinco áreas do referido estuário. O Talha-mar foi uma ave constante durante todo o ano no estuário de Cananéia-Iguape-Ilha Comprida. Um total de 48 censos foi realizado em cada uma das cinco áreas escolhidas. Os resultados indicaram que o Talha-mar foi uma espécie comum no estuário de Cananéia-Iguape-Ilha Comprida e o número de indivíduos variou em função da área de estudo. O talha-mar foi mais freqüente observado no Baixio do Arrozal (Cananéia), no verão e outono, no verão-inverno no Boqueirão Sul e Norte... |

| Many Neartic seabirds migrate to South America for the non-breeding season, using several key stopover and wintering sites along the Atlantic coast. The Stercorarius pomarinus is a widely distributed seabird found in every Ocean. It is a migratory bird from northern North America that flies southwards. However, there is little information about the occurrence of Stercorarius pomarinus along the São Paulo State coast. Former publications concerning the birds of Iguape- Cananéia- Ilha Comprida estuary have made no mention of the presence of this bird in the region. Thus it is important that forthcoming appearances be recorded. Throughout the bird-sample selection stage, undertaken since 1998 in the Cananéia estuary (25° 02' 44.71" S and 47° 55' 14.58" W) -... |

| Birds were censused weekly from January 1999 to January 2001 along Ilha Comprida beach, a barrier island off São Paulo, southeastern Brazil. To evaluate the similarity in the bird's species composition among the weekly surveys, species counts data were arranged on a data matrix with 144 weekly surveys, analyzed following a multivariate analysis protocol. We counted a total of 205,399 individuals and 52 species. Migratory birds were an important component of the avifauna (maximum N = 21,294 individuals and 14 species). The largest numbers of birds were observed during summer, when Nearctic migrants arrive. All 14 of the most common species were migrants, including Calidris alba, Sterna maxima, Charadrius semipalmatus, Sterna hirundo, Thalasseus maximus,... |

| A pesca artesanal dirigida ao camarão sete-barbas (Xiphopenaeus kroyeri), usando o método de arrasto motorizado com portas, tem sido praticada na costa de Santa Catarina, onde ele gera emprego e renda, e ajuda a manter a tradição cultural tradicional açoriana viva, desde 1960. Com o objectivo de analisar a qualidade e a quantidade das capturas acidentais da ictiofauna, efetuou-se sazonalmente, dois arrastos por isóbata (10-20‑30 m) entre novembro/2009 e agosto/2010, duração de 20 min/cada, velocidade média dois nós e, registrados temperaturas e salinidades da água de fundo. As capturas totalizaram 10868 peixe (208.34 kg), distribuídos em 31 famílias e 62 espécies, com uma proporção de peixe/camarão de 5,19/1 kg. A família mais abundante foi Sciaenidae... |

| Foram registradas as freqüências de ocorrências e as flutuações mensais das famílias Charadriidae e Scolopacidae ao longo de um transecto de 70 km de praia entre o Boqueirão Sul e o Boqueirão Norte na Ilha Comprida, estado de São Paulo, durante o período de um ano (Janeiro a dezembro de 2010). Um total de 12.153 indivíduos de aves foram contados com a maior abundância ocorreu entre outubro e abril e a mais baixa entre maio a setembro. Das 20 espécies registradas as mais abundantes foram Charadrius semipalmatus, Charadrius colaris, Vanellus chilensis e Tringa flavipes. As menos abundantes foram Tryngites subruficolis, Limosa haemastica,Tringa melanoleuca e Actitis macularia. Dezesseis espécies eram migrantes do Hemisfério Norte, duas migrantes do Hemisfério... |

| Despite being widely distributed in South America and having relatively large populations, little is known about the trophic ecology of the South American Tern (Sterna hirundinacea) and Cabot's Tern (Thalasseus acuflavidus). In Brazil, South American and Terns Cabot's breed in mixed colonies from the state of Espírito Santo to Santa Catarina. Here, we describe results of a study of the feeding ecology of these two species during the reproductive seasons of April to October of 2003, 2005 and 2006 from Cardos Island, Santa Catarina, Brazil. A total of 6248, 5140, and 4006 fishes were delivered to chicks or females by South American Terns; and 1157, 628 and 98 fish and or other prey items by Cabot's Terns during the breeding seasons of 2003, 2005, and 2006,... |

| This study aimed to investigate the toxicological effects of the LAS-C12 on Mugil platanus (mullet). Fishes exposed to 1.0 mg.L-1 for 24, 48, 72, 96 and 120 hours presented significant increase in specific routine metabolism. At the concentration of 0.5 mgL-1, the active metabolism presented a decreasing trend from 48 h of exposure on. However, only the consumption averages for 72 h were statistically different from the ones obtained for other periods of exposure. The lowest oxygen consumption in this concentration was observed for 24, 48 and 72 hours of exposure. Significant differences between the control and the concentration of 2.5 mgL-1 were observed for the different periods of exposure. It was not possible to measure the consumption of oxygen for 96... |

| Seabirds ingest plastic particles floating on the surface of the world's oceans. The birds can ingest plastic particles that they mistakenly identify as prey items. Alternatively, plastics can be taken up in the stomach contents of prey species. Plastic is often passed from parents to chicks in regurgitated food. In this study, individual petrels and albatrosses brought in by the tide onto Ilha Comprida beach between January 2000 and December 2002 were collected. Ilha Comprida, a barrier island in southern São Paulo, Brazil, was traversed by car along a transect of 70 kilometers. A total of 110 birds of 10 species were collected and 64.54% had plastic particles in their stomach. Frequencies of occurrence were Macronectes giganteus (64.28%), Thalassarche... |
