Abstract	Abstract The introduction of non-indigenous marine species in new habitats is generally associated with ships arriving at ports, driven by species transported in ballast water and sediment and biofouling communities on ship hulls, drifting object and underwater surfaces in dock areas. The present paper reports the record of the specie Sternaspis aff. nana in the Atlantic Ocean, discussing its possible conservation status and method of arrival to Brazil. Sediments samples were collected in the external area (11 m depth) of the Suape Harbor (Brazil) in February 2018. Two individuals of Sternaspis aff. nana were recorded, representing the first record of this species in the Southwest Atlantic Ocean. The way S. aff. nana arrived in Brazilian waters cannot be easily determined, the short-lived lecithotrophic larvae of sternaspids suggest that the specimens found in Suape have arrived in ballast sediment. An increase in trade between Brazil and Asian countries since the 2000s has led to that more ships coming from China having arrived in Brazilian harbors. The arrival of S. aff. nana, originally described in the South China Sea, in the Suape harbor area may have resulted from this intense movement of ships between China and Brazil.

Abstract	The structural complexity of algae is an important factor driving the structure of epifaunal assemblages associated with marine macroalgae. We tested how the structural complexity of four Sargassum species is related to the structure of gammarid assemblages. We measured different algae traits (frond length, number of branches, and epiphytic hydroid and algae cover) and different ecological descriptors of gammarid assemblages (richness, density, diversity, and evenness). Samples were obtained in southeastern Brazil in early and late summer. Structural complexity was associated with the occurrence of significantly different gammarid assemblages. Sargassum cymosum had more branches and greater hydroid coverage, and a higher gammarid species richness, diversity, and density. The characteristics of the gammarids inhabiting the different Sargassum species were similar between sampling periods, indicating that the relationships between the Sargassum traits and associated gammarids are strong and persistent. Species richness, diversity, and density were all more dependent on habitat heterogeneity (number of branches and coverage of epiphytic hydroid) than the quantity of habitable space, i.e., frond length. Overall, the variation in structural complexity among Sargassum species had a significant effect on gammarid assemblage structure.

Abstract	We used complementary stable isotope (SIA) and stomach content (SCA) analyses to investigate feeding relationships among species of the nektobenthic communities and the potential ecological effects of the bottom trawling of a coastal ecosystem in northeastern Brazil. Carbon (δ13C) and nitrogen (δ15N) compositions were determined for five basal sources and 28 consumers, from zooplankton to shrimp and fish species. Fishes and basal sources showed a broad range of δ15N (fishes: 6.49-14.94‰; sources: 2.58-6.79‰) and δ13C values (fishes: -23.86 to -13.71‰; sources: -24.32 to -13.53‰), while shrimps and crabs exhibited similar nitrogen and carbon ratios. Six trophic consumer groups were determined among zooplankton, crustaceans and fishes by SIA, with trophic pathways associated mostly with benthic sources. SCA results indicated a preference for benthic invertebrates, mainly worms, crabs and shrimps, as prey for the fish fauna, highlighting their importance in the food web. In overall, differences between SCA and the SIA approaches were observed, except for groups composed mainly for shrimps and some species of high δ15N values, mostly piscivorous and zoobenthivores. Given the absence of regulation for bottom trawling activities in the area, the cumulative effects of trawling on population parameters, species composition, potentially decreasing the abundance of benthic preys (e.g., shrimps, worms and crabs) may lead to changes in the trophic structure potentially affect the food web and the sustainability of the fishery.

Abstract	Ecological models derived from Optimal Foraging Theory have been used to understand the decision-making processes and optimization of artisanal fisheries. However, many studies do not consider the influence of fishing techniques or seasonality on foraging strategies. We analyzed the optimization strategies and decision-making processes of the fishers at a Brazilian reservoir. Data were collected through interviews and questionnaires involving 65 artisanal fishers, and daily catches were monitored in July/2015 and January/2016. Fishing techniques and seasonality influenced the fishers’ behavior. The fishery activities monitored here were partially or totally consistent with the predictions of the Central-Place Foraging model, but due to the complexity of these activities, other factors also influenced the decision-making of individual fishers. Furthermore, the adoption of strategies that involve “non-ideal” behaviors may be advantageous for the fishers in the context of their individual necessities.

Abstract	This study aimed to predict the biological parameters (species composition, abundance, richness, diversity and evenness) of benthic assemblages in southern Brazil estuaries using models based on environmental data (sediment characteristics, salinity, air and water temperature and depth). Samples were collected seasonally from five estuaries between the winter of 1996 and the summer of 1998. At each estuary, samples were taken in unpolluted areas with similar characteristics related to presence or absence of vegetation, depth and distance from the mouth. In order to obtain predictive models, two methods were used, the first one based on Multiple Discriminant Analysis (MDA), and the second based on Multiple Linear Regression (MLR). Models using MDA had better results than those based on linear regression. The best results using MLR were obtained for diversity and richness. It could be concluded that the use predictions models based on environmental data would be very useful in environmental monitoring studies in estuaries. Este trabalho objetivou predizer parâmetros da estrutura de associações macrobentônicas (composição específica, abundância, riqueza, diversidade e equitatividade) em estuários do Sul do Brasil, utilizando modelos baseados em dados ambientais (características dos sedimentos, salinidade, temperaturas do ar e da água, e profundidade). As amostragens foram realizadas sazonalmente em cinco estuários entre o inverno de 1996 e o verão de 1998. Em cada estuário as amostras foram coletadas em áreas não poluídas, com características semelhantes quanto a presença ou ausência de vegetação, profundidade e distância da desenbocadura. Para a obtenção dos modelos de predição, foram utilizados dois métodos: o primeiro baseado em Análise Discriminante Múltipla (ADM) e o segundo em Regressão Linear Múltipla (RLM). Os modelos baseados em ADM apresentaram resultados melhores do que os baseados em regressão linear. Os melhores resultados usando RLM foram obtidos para diversidade e riqueza. É possível então, concluir que modelos como aqui derivados podem representar ferramentas muito úteis em estudos de monitoramento ambiental em estuários.

Abstract	The macrobenthic community structure was studied in inter-tidal, non-vegetated areas of the Caeté river estuary, Pará, Brazil, during the dry season of 2003. Four samples were collected at four stations on the downstream direction (P1 to P4) using a corer (0.008 m2 and 20 cm long). Samples were sieved through a 0,3 mm mesh and the organisms preserved in a 5% formaline saline solution stained with Bengal rose. At each station, sediment samples were collected and salinity and water temperature recorded. A total of 105,500 individuals were collected, divided in 17 taxa comprising the fphyla: Nemertea, Arthropoda and Annelida. Polychaeta dominated the assemblages (11 taxa and 87.25% of the individuals). The most abundant taxa were Mediomastuscalifornienses, Nephtys Huviatilisand Oligochaeta (Tubificidae). Density and richness values varied from 2625 ind.m-2 and 3 taxa at station P1 to 96625 ind.m-2 among 16 taxa at station P4. Cluster analysis seperated three groups (50% similarity): Group 1, including samples from stations P3 and P4, was characterized by a relatively high salinity (22.6 to 26.5) and a fine sand substrate. This group, dominated by Sigambra grubii, was the richest (13 taxa), most diverse (χH´ = 1.18) and abundant (χ= 12220 ind.m-2); Group 2, including samples from station P1, was characterized by a salinity of 5,1 and a silt-sandy substrate. This group presented the lowest richness (3 taxa), diversity (χH´ = 0.67) and abundance (χ= 665 ind.m-2) values, and was dominated by the species Namalicastysabiuma; and Group 3, including samples from station P2, was characterized by a salinity of 3.6 and a silt-sandy substrate. N. abiuma was the most abundant species of this group that was characterized by intermediate richness (5 taxa), abundance (χ= 2010 ind.m-2) and diversity (χH´ = 0.71) values. Thus, it is concluded that in the inter-tidal area of the non-vegetated Caeté river the species number is low; Annelida is the most abundant group; the species composition reflects the estuary salinity gradient; and ...

Abstract	A estrutura das comunidades macrobentônicas de zonas entre-marés não vegetadas do estuário do rio Caeté, Pará, Brasil foi estudada no período menos chuvoso de 2003. Foram tomadas amostras (n=4) em quatro estações utilizando um corer (0,008 m2, 20 cm de altura). As amostras foram passadas em malha de 0,3 mm e os organismos fixados com formalina salina a 5%. Em cada estação foi coletada uma amostra de sedimento e determinadas a salinidade e temperatura da água. Foram registrados 844 espécimes pertencentes a 17 táxons dos filos Nemertinea, Arthropoda e Annelida. Polychaeta dominou as associações (11 táxons e 87,25% do total de indivíduos). Os táxons mais abundantes foram Mediomastus californienses, Nephtys fluviatilis e oligoquetas Tubificidae. Os valores de abundância e riqueza passaram de 2625 ind.m-2 em P1 para 96625 ind.m-2 em P4 e, respectivamente de 3 para 16 táxons. A análise de agrupamento revelou a formação de três grupos (50% de similaridade). O grupo 1, formado pelas estações P3 e P4, teve alta salinidade (22,6 a 26,5), substrato constituído por areia muito fina, foi o grupo mais rico (13 táxons), diverso (χH´ = 1,18) e abundante (χ= 12220 ind.m-2), sendo dominado por Sigambra grubii. O grupo 2 reuniu as amostras da estação P1, com salinidade de 5,1, substrato silte-arenoso, e registros dos valores mais baixos de riqueza (3 táxons), diversidade (χH´ = 0,67) e abundância (χ= 665 ind.m-2), cuja espécie mais abundante foi Namalicastys abiuma. O grupo 3, formado pelas amostras da estação P2, teve substrato silte-arenoso e salinidade 3,6. N. abiuma foi a espécie mais abundante nesse grupo, que teve valores intermediários de riqueza (5 táxons), abundância (χ= 2010 ind.m-2) e diversidade (χH´ = 0,71). É possível concluir que, no médio litoral não vegetado do rio Caeté, o número de espécies é baixo, Annelida é o grupo dominante, a composição específica reflete o gradiente de salinidade e a riqueza, diversidade e abundância aumentam na medida em que se passa do estuário superior para o inferior.
