1. Spatial Distribution and Pollution Assessment of Trace Elements Pb, Cu, Ni, Fe and As in the Surficial Water of Staring Bay, Indonesia
Staring Bay has long been used by the local community for fisheries and fishing activities; however, the rapid population growth and industrial activities around the bay in recent years are predicted to contribute significantly to the increase of waste entering the bay. This particular study was aimed to provide baseline levels of trace elements Pb, Cu, Ni,

2. Range distribution and contributions to taxonomy of Elops smithi (ELOPIFORMES: ELOPIDAE)
Abstract: This study presents the first record of Elops smithi for northern Brazil. The evidence suggests this species is being misidentified incorrectly as Elops saurus in estuaries of the Western Atlantic Ocean. Here, morphological, molecular, and cytogenetic evidence identified all ladyfish specimens from one estuary in the region as E. smithi. Thus, at l

3. Zn, Co, Cr, As, and genotoxic effects in the ichthyofauna species from polluted and non-polluted/protected estuaries of the São Paulo coast, Brazil
Abstract: The human impact on estuarine regions results in an increasing concentration of trace elements in the environment, exposing aquatic organisms. In this study, Zn, Co, Cr, and As were determined in the muscle tissue of some fish species from Santos-São Vicente (SSV), a recognized polluted region, and in the Cananeia estuary (CAN). Genotoxicity was a

4. Continental fishes from the Tambaba Environmentally Protected Area, Paraíba State, Brazil
Abstract Tambaba environmentally protected area is situated on the south coast of Paraíba State, within the Atlantic forest biome of the northeastern region in Brazil. The Tambaba environmentally protected area consists of a series of independent drainages: Graú, Mucatú, and Bucatú river micro-basins, and Caboclo River sub-basin that belongs to Gurugi Ri

5. Salinity regulation of copepod egg production in a large microtidal estuary
ABSTRACT Salinity is a key variable for ecological processes in estuaries. Acartia tonsa is a typical estuarine copepod whose responses to salinity have been thoroughly studied in the laboratory. However, results cannot be extrapolated to the field, and formal comparisons between lab and field responses to salinity were not attempted. Here we compare lab-bas

6. Impactos da mudança de vegetação local no aporte de matéria orgânica para um estuário tropical preservado (Estuário do Rio Itapicuru – BA)
Estuaries are major areas of organic matter (OM) deposition, playing an important role in the global carbon cycle. The Itapicuru's river estuary (IRE) is in the North Coast of Bahia (Brazil), in na Environmental Protected Area. Although it presents preserved conditions, some environmental changes caused by human activities can be observed. This study evaluat

7. Trophic dynamics (Dissolved Inorganic Nitrogen-DIN and Dissolved Inorganic Phosphorus-DIP) in tropical urban estuarine systems during periods of high and low river discharge rates
Abstract: This paper focused on the use of the biogeochemical LOICZ (Land Ocean Interactions in the Coastal Zone) to investigate the dynamics of DIN and DIP nutrients among three highly urbanized tropical estuaries (Barra das Jangadas (BJ), Recife (RE) and Timbó (TB)), located in the northeastern region of Brazil. The input data were obtained through in sit

9. Revision of Bairdiella (Sciaenidae: Perciformes) from the western South Atlantic, with insights into its diversity and biogeography
RESUMO O gênero Bairdiella compreende um grupo de peixes relativamente pequenos encontrados em águas costeiras e estuários do Atlântico ocidental e leste do Pacífico. Apesar das análises recentes das relações filogenéticas de Bairdiella, não houve revisão abrangente da taxonomia alfa das espécies do gênero. Bairdiella ronchus, do Atlântico ocid

10. Cetacean movements in coastal waters of the southwestern Atlantic ocean
Resumo: Cetáceos foram monitorados em cerca de 700 km da costa sudeste do Brasil (22°S a 25°S) entre 1995 e 2014 com o uso da fotoidentificação. O objetivo deste estudo foi de identificar quaisquer presenças de movimentos de longa distância de indivíduos das espécies monitoradas e discutir suas implicações. Dados de movimentos de longa distância

11. Alkalinity, inorganic carbon and CO2 flux variability during extreme rainfall years (2010-2011) in two polluted tropical estuaries NE Brazil
Resumo A suscetibilidade dos ambientes costeiros às mudanças nos ciclos biogeoquímicos do carbono e nutrientes impulsionados pela pressão antrópica e mudanças climáticas é um verdadeiro desafio para a comunidade científica. Este artigo avaliou os efeitos de um evento de precipitação extrema sobre os parâmetros de oxigênio, nutrientes e do sistem

12. Potentially mobile of heavy metals on the surface sediments in tropical hyper-saline and positive estuaries
ABSTRACT Estuarine sediments represent important pools of trace metals, released from both anthropogenic and natural sources. Fluctuations in the water column physicochemical conditions, on the other hand, may transfer metals from solid to liquid compartment and resulting in contamination of the surrounding environment. The present research was carried out t
