Resource partitioning in sympatric delphinids: Space use and habitat preferences of Australian snubfin and Indo-Pacific humpback dolphins

1. Many species of delphinids co-occur in space and time. However, little is known of their ecological interactions and the underlying mechanisms that mediate their coexistence. 2. Snubfin Orcaella heinsohni, and Indo-Pacific humpback dolphins Sousa chinensis, live in sympatry throughout most of their range in Australian waters. I conducted boat-based surveys in Cleveland Bay, north-east Queensland, to collect data on the space and habitat use of both species. Using Geographic Information Systems, kernel methods and Euclidean distances I investigated interspecific differences in their space use patterns, behaviour and habitat preferences. 3. Core areas of use (50% kernel range) for both species were located close to river mouths and modified habitat such as dredged channels and breakwaters close to the Port of Townsville. Foraging and travelling activities were the dominant behavioural activities of snubfin and humpback dolphins within and outside their core areas. 4. Their representative ranges (95% kernel range) overlapped considerably, with shared areas showing strong concordance in the space use by both species. Nevertheless, snubfin dolphins preferred slightly shallower (1-2 m) waters than humpback dolphins (2-5 m). Additionally, shallow areas with seagrass ranked high in the habitat preferences of snubfin dolphins, whereas humpback dolphins favoured dredged channels. 5. Slight differences in habitat preferences appear to be one of the principal factors maintaining the coexistence of snubfin and humpback dolphins. I suggest diet partitioning and interspecific aggression as the major forces determining habitat selection in these sympatric species.

FATORES DETERMINANTES DA SOBREVIVÊNCIA DAS MICRO E PEQUENAS EMPRESAS DO SETOR INDUSTRIAL NA CIDADE DE SANTOS

A importância das micro e pequenas empresas na economia brasileira já é sentida desde há muito tempo, pois esse segmento é fundamental na geração de riqueza para a sociedade. Apesar da importância econômica, ainda persiste um elevado grau de descontinuidade nas mesmas, o que lhes outorga dificuldades de transporem os dois primeiros e mais críticos anos de existência. Esta pesquisa visa identificar os fatores determinantes da sobrevivência das micro e pequenas empresas do setor industrial na cidade de Santos. A relevância do estudo se intensifica em decorrência da cidade de Santos estar vivenciando um momento de desenvolvimento econômico impulsionado pelas descobertas de petróleo na camada do pré-sal. Isso poderá aumentar ainda mais o número de criação de MPEs, principalmente no setor industrial, e que provavelmente necessitarão de informações nas quais possam se espelhar. O estudo é de caráter exploratório e descritivo. Os dados foram colhidos por meio de uma pesquisa de campo com aplicação de um questionário baseado em quatro dimensões: empreendedorismo, ambiental, recursos financeiros e organização interna. A pesquisa apresentou como principais fatores de sobrevivência o tempo dedicado à empresa; a adequação dos produtos a demanda; a capacidade de assumir riscos e a liderança do gestor. A amostra de estudo foi definida por conveniência, constituída de MPEs pertencentes ao setor econômico industrial, pois é o mais aderente à cadeia de exploração de petróleo. Foram consideradas as empresas que ultrapassaram os dois primeiros anos de existência, de acordo com os critérios de avaliação de sobrevivência adotado pelo SEBRAE (2011).

Performance improvement of asymmetrical filtered 40GB/s RZ-DPSK receiver design-strong filtering considerations

We present a novel differential phase shift keying receiver design under strong optical filtering. The receiver design is based on asymmetrical filtering at the destructive port of the Mach Zehnder Interferometer. The asymmetrical filtered receiver design can significantly increase performance by 2 to 4.7dB in calculated "Q".

Ex Ante Cost Benefit Analyses of Community-Based DRR Interventions in the Caribbean

This report presents a study on the cost benefit analyses (CBA) and cost effectiveness analysis (CEA) of community-based disaster risk reduction (DRR) interventions in the Caribbean. The DRR interventions, implemented by the International Federation of Red Cross (IFRC), Port of Spain, in three Caribbean countries, Jamaica, Antigua & Barbuda, and Suriname, comprised the pilot phase of the Red Cross (RC) Project, Improving Climate Change Resilience of Caribbean Communities. This study is part of the endeavor by the DRR Program of Florida International University (FIU) and the United States Agency for International Development’s Office of the U.S. Foreign Disaster Assistance (USAID/OFDA) to develop and foster DRR measures in the Latin American and Caribbean region since 2008.

Morphometrics of seagrasses at species level, Moreton Bay, Australia determined from core samples collected in 2012-2013

Seagrass meadows are important marine carbon sinks, yet they are threatened and declining worldwide. Seagrass management and conservation requires adequate understanding of the physical and biological factors determining carbon content in seagrass sediments. Here, we identified key factors that influence carbon content in seagrass meadows across several environmental gradients in Moreton Bay, SE Queensland. Sampling was conducted in two regions: (1) Canopy Complexity, 98 sites on the Eastern Banks, where seagrass canopy structure and species composition varied while turbidity was consistently low; and (2) Turbidity Gradient, 11 locations across the entire bay, where turbidity varied among sampling locations. Sediment organic carbon content and seagrass structural complexity (shoot density, leaf area, and species specific characteristics) were measured from shallow sediment and seagrass biomass cores at each location, respectively. Environmental data were obtained from empirical measurements (water quality) and models (wave height). The key factors influencing carbon content in seagrass sediments were seagrass structural complexity, turbidity, water depth, and wave height. In the Canopy Complexity region, carbon content was higher for shallower sites and those with higher seagrass structural complexity. When turbidity varied along the Turbidity Gradient, carbon content was higher at sites with high turbidity. In both regions carbon content was consistently higher in sheltered areas with lower wave height. Seagrass canopy structure, water depth, turbidity, and hydrodynamic setting of seagrass meadows should therefore be considered in conservation and management strategies that aim to maximize sediment carbon content.

Especiação química de arsênio inorgânico no estuário da Lagoa dos Patos-RS

A poluição das águas por metais, principalmente os metais pesados, vem chamando a atenção no mundo, pois estes poluentes aquáticos representam um risco em potencial, devido ao seu caráter acumulativo. Entre os metais, o arsênio recebe destaque pelo seu potencial tóxico. O arsênio inorgânico ocorre na natureza em quatro estados de oxidação: As5+, As3+, As0 e As3- . O estado de oxidação do arsênio tem um papel importante no seu comportamento e toxicidade nos sistemas aquáticos. Pelo fato do arsênio ser extremamente perigoso e nocivo para o meio ambiente, novos métodos analíticos de especiação química no meio ambiente têm sido publicados. Neste estudo foi otimizado e validado um método para realizar a especiação química de arsênio inorgânico presente em amostras de água coletadas nos meses de julho e outubro de 2010 no estuário da Lagoa dos Patos (RS, Brasil), como parte das atividades do Programa de Monitoramento Ambiental do Porto do Rio Grande-RS. Foi usada a técnica de espectrometria de absorção atômica com geração de hidretos e injeção em fluxo (FI-HG AAS), podendo ser quantificadas espécies de As3+ e As5+ nas amostras de água estuarina. A concentração do arsênio trivalente inorgânico foi determinada, após adição de solução tampão citrato de sódio (0,4 mol L-1 ; pH = 6,0). A concentração de arsênio inorgânico total foi determinada, após uma etapa de pré-redução da espécie pentavalente para a forma trivalente usando uma mistura de iodeto de potássio, ácido ascórbico em meio ácido clorídrico concentrado. A concentração de arsênio pentavalente foi calculada pela diferença das concentrações de arsênio inorgânico total e trivalente. A interpretação dos resultados gerados pelo método proposto usado ao analisar amostras de águas coletadas no estuário da Lagoa dos Patos foi feita pela análise dos componentes principais. Os dados tratados estatisticamente revelaram uma interação significativa neste estudo entre o arsênio, o material em suspensão (MS) e o NH4 + na superfície da coluna d’água no período da primavera.

An identification procedure of multi-input Wiener models for the distortion analysis of nonlinear circuits

In this contribution, a system identification procedure of a two-input Wiener model suitable for the analysis of the disturbance behavior of integrated nonlinear circuits is presented. The identified block model is comprised of two linear dynamic and one static nonlinear block, which are determined using an parameterized approach. In order to characterize the linear blocks, an correlation analysis using a white noise input in combination with a model reduction scheme is adopted. After having characterized the linear blocks, from the output spectrum under single tone excitation at each input a linear set of equations will be set up, whose solution gives the coefficients of the nonlinear block. By this data based black box approach, the distortion behavior of a nonlinear circuit under the influence of an interfering signal at an arbitrary input port can be determined. Such an interfering signal can be, for example, an electromagnetic interference signal which conductively couples into the port of consideration. © 2011 Author(s).

Influence of a Brazilian sewage outfall on the toxicity and contamination of adjacent sediments

The submarine sewage outfall of Santos (SSOS) is situated in the Santos Bay (São Paulo, Brazil) and is potentially a significant source of contaminants to the adjacent marine ecosystem. The present study aimed to assess the influence of SSOS on the sediment toxicity and contamination at Santos Bay. At the disposal site, sediments tended to be finer, organically richer and exhibited higher levels of surfactants and metals, sometimes exceeding the Threshold Effect Level values. The SSOS influence was more evident toward the East, where the sediments exhibited higher levels of TOC, total S and metals during the summer 2000 sampling campaign. Sediment toxicity to amphipods was consistently detected in four of the five stations studied. Amphipod survival tended to correlate negatively to Hg, total N and % mud. This work provides evidence that the SSOS discharge affects the quality of sediments from Santos Bay, and that control procedures are warranted. (c) 2005 Elsevier Ltd. All rights reserved.
