Optical particle measurements are emerging as an important technique for understanding the ocean carbon cycle, including contributions to estimates of their downward flux, which sequesters CO2 in deep sea. instruments can be used from ships or installed on autonomous platforms, delivering much greater spatial and temporal coverage particles mesopelagic zone than traditional techniques, such sediment traps. Technologies image have advanced greatly over last two decades, but quantitative...
The analysis of plankton size distributions in response to physical and biological forcing is relevant the understanding marine ecological processes. In this study, we evaluated influence seasonal intrusions South Atlantic Central Water (SACW) on zooplankton vertical distribution normalized biomass spectra (NBSS) inner shelf off subtropical Brazil. Monthly sampling was performed at a fixed station for 5 years samples were analyzed with ZooScan system. SACW led increases nitrate, chlorophyll...
Abstract The inner shelf waters off Southeastern Brazil are periodically enriched by bottom intrusions of the cold and nutrient‐rich South Atlantic Central Water ( SACW ), which is transported offshore Current. This study examined temporal contrasts in abundance structure pelagic copepod assemblages a neritic station Ubatuba, relation to hydrography phytoplankton biomass, investigate effects on population dynamics during three consecutive years. water‐column characteristics shifted from...
The objective of this study was to describe the composition two mesozooplankton and ichthyoplankton estuarine communities in Jandaíra, Bahia (Tabatinga River), impacted by a shrimp farm; Conde, (Itapicuru pristine estuary. Samples were collected through horizontal hauls using net (200 μm mesh size), coupled flowmeter, during ebbing flooding tides April, August December, 2007. In Tabatinga Itapicuru Rivers 76 92 taxa registered. most abundant groups Pseudodiaptomus richardii Disco sp. Acartia...
We investigated the influence of oceanic fronts on mesozooplankton distribution and grazing activity in south-west Atlantic. Sampling was conducted during late spring 1993 along a north–south transect between subtropical waters off Brazil Antarctic waters. Mesozooplankton abundance biomass were ~10-fold higher Subtropical Confluence Zone (SCZ) Polar Front (APF) relative to subantarctic beyond those frontal systems. dominated by calanoid cyclopoid copepods. Community ingestion rates ranged...
Abstract For over 50 years, the conceptualisation of low-nutrient oligotrophic systems having longer food chains and thus lower energy transfer to fish than their high-nutrient eutrophic counterparts 1 has achieved status an ecological paradigm. However, recent global assessments indicate biomass could be much higher previously thought 2–4 , suggesting that our traditional understanding webs may need revisited. Here, we challenge classical paradigm by exploring role zooplankton in across...
Este estudo teve como objetivo avaliar a qualidade da água das microbacias dos rios Jardim e Mutari, situadas no Extremo Sul Bahia, através avaliação de parâmetros físicos, químicos, microbiológicos do uso ocupação terra. Para isso foram realizadas quatro coletas, em abril, maio, julho outubro 2019, 8 pontos amostrais, selecionados acordo com possíveis fontes pontuais difusas poluição. Foram analisados os temperatura, potencial hidrogeniônico (pH), salinidade, oxigênio dissolvido (OD),...
The accuracy of traditional methods to sample planktonic microcrustaceans depends on two assumptions: that organisms are alive during sampling and all carcasses can be identified despite their degradation state, but fresh not easy distinguish by methods. Previous studies about mortality have shown neglecting dead provide biased ecological information. Thus, our objective was determine the rate proportion microcrustacean in three tropical reservoirs. Sampling carried out 12 stations periods....

Abstract The South Atlantic Ocean (SAO) is an under‐sampled ocean where the influence of environmental drivers on copepod body size poorly understood. This study investigated distribution copepods from 13°S to 64°S test Bergmann's rule, which predicts occurrence smaller organisms in warmer areas. We hypothesized that additional oceanographic features strengthens this pattern. Zooplankton were sampled during austral summer chlorophyll maximum depth up surface, at approximately 100 m depth,...
Avaliamos a cadeia produtiva do pescado consumido no Estado da Bahia utilizando Análise de Ciclo Vida (ACV). Estimamos os consumos e emissões associados í logística ao processamento peixe. O Potencial Aquecimento Global (PAG) foi calculado com base na quantidade Gases Efeito Estufa (GEE) indicadas por kg CO2eq para cada peixe processado foram: 0,020 - eletricidade; 0,003 í consumo água; 0,0029 efluentes; 0,160 1,495 resíduos sólidos peixes eviscerados filetados, respectivamente, 0,871...
O pier municipal de Porto Seguro está localizado em uma zona estuarina na foz do rio Buranhém, local transição entre o e mar. plâncton da região sul Bahia é pouco estudado, os estuários são conhecidos por serem ambientes com grandes quantidades nutrientes que provém dos continentes, aumenta produtividade primária (fitoplâncton) sua vez favorece aumento secundária, zooplâncton. zooplâncton foi coletado redes 68 200 μm arrastos verticais, no período setembro 2019 até agosto 2020 nas marés...
