1. Antibiotic resistance in surface waters from a coastal lagoon of Southern Brazil under the impact of anthropogenic activities
Resumo Resíduos oriundos de atividades humanas podem atingir corpos d'água e contribuir significativamente para a presença de populações bacterianas resistentes a antibióticos. O objetivo deste estudo foi avaliar populações de bactérias cultiváveis resistentes a antibióticos em uma lagoa costeira impactada por atividades como agricultura e urbaniz

2. Organic matter composition related to methane ebullitive flux of an urban coastal lagoon, Southeastern Brazil
In 2016, Brazil emitted 18.25 Tg of methane. Some of these emissions occur through continental aquatic ecosystems, locations of fate and accumulation of organic and inorganic matter. Thus, the aim of this study is to evaluate the origin of organic matter in Rodrigo de Freitas Lagoon, an eutrophic, coastal and chocked lagoon in Rio de Janeiro, Brazil, through

3. Crane flies (Diptera, Tipuloidea) from southern Neotropical salt marshes: survey with DNA barcoding
ABSTRACT Crane flies are the most diverse group within Diptera, but they are rarely studied in coastal ecosystems. Considering the scarcity of information on the biology and ecology of this group in the Neotropics, and the sparse literature available for taxonomic identification, we developed a descriptive checklist that incorporates morphology and DNA barco

4. Ichthyofauna of Trairí river basin, Rio Grande do Norte state, northeastern Brazil: a century after the study of the naturalist Edwin Starks in the Papari lagoon
Abstract Fishes from the coastal basins of the Mid-Northeastern Caatinga ecoregion (MNCE) were first sampled by the Stanford expedition at the beginning of the 20th century, and published by Edwin C. Starks in 1913. This material included specimens from the Papary lake (= Papari lagoon) in the lower portion of the Trairí river basin, draining towards the ea

5. Evaluation of the Concentration of Cu, Zn, Pb and Cr in Different Fish Species from the São Gonçalo Channel in Pelotas-RS, Brazil
The objective of this study was to evaluate the concentration of Cu, Zn, Cr and Pb in different species of fish collected in the estuarine and limnic regions of the São Gonçalo channel, located in the Patos-Mirim lagoon complex in the coastal plain of Rio Grande do Sul State (Southern Brazil) during 2013 (autumn, winter and spring) and 2014 (summer).

6. Comparative analysis of diet composition and its relation to morphological characteristics in juvenile fish of three lutjanid species in a Mexican Pacific coastal lagoon
ABSTRACT The main goal of this research was to investigate the differences in diet composition among three species of the genus Lutjanus inhabiting a coastal lagoon as juveniles. The working hypothesis was that these species feed on a common base of food resources and therefore, some niche overlap is present in terms of general diet composition. However, cha

7. Floating Aquatic Macrophytes Decrease the Methane Concentration in the Water Column of a Tropical Coastal Lagoon: Implications for Methane Oxidation and Emission
ABSTRACT In wetlands, the knowledge accumulated on the role of aquatic plants in the methane cycle focused on emergent macrophytes, to the detriment of other typologies. Herein, we evaluated whether the free-floating macrophyte Salvinia auriculata Aubl. and the floating-leaved macrophyte Eichhornia azurea (Sw.) Kunth. decrease the water column methane concen

8. Macrobenthos of the coastal Budi Lagoon, southern Chile: Changes associated with seasonal environmental variation
Resumo O objetivo do presente estudo foi investigar a relação sazonal entre macrobentos e características do sedimento, tais como textura e material orgânico, na lagoa costeira Budi Lagoon, sul do Chile. Medidas físico-químicas e amostragem do macrobentos foram realizadas durante um ano em nove localidades. Sedimento arenoso-lodoso foi o mais comum na

9. Carbon primary sources and estuarine habitat use by two congeneric ariid catfishes in a subtropical coastal lagoon
ABSTRACT Although ariid catfishe species are known to use coastal systems during some stages of their life cycles, the energetic contribution of estuarine resources and habitat use by many species in this family are still unclear. We used stable isotope analyses to estimate the assimilation of primary carbon sources and to infer the use of estuarine and fres

10. Aspects of the reproductive biology of the freshwater/brackish amphipod Quadrivisio lutzi (Crustacea, Amphipoda) from an unstable coastal lagoon of southeastern Brazil
ABSTRACT The amphipod Quadrivisio lutzi (Shoemaker, 1933) (Maeridae) inhabits the coastal lagoons of southeastern Brazil, which are highly unstable environments. Drastic reduction in the abundance and distribution of this amphipod on these lagoons has been observed. The constant recovery of its populations suggests that this species may show a reproductive s

11. Reproduction of Brevoortia aurea (Spix & Agassiz, 1829) (Actinopterygii: Clupeidae) in the Mar Chiquita Coastal Lagoon, Buenos Aires, Argentina
RESUMO Se estudió la biología reproductiva de la saraca, Brevoortia aurea (Clupeiformes), en la Laguna Costera Mar Chiquita. Se analizó su abundancia, en relación con las variables ambientales y se estimaron los principales parámetros biológico-reproductivos: talla de primera madurez (longitud total), fecundidad parcial y relativa, distribución de fre

12. Abundance and distribution of Portunidae larval phases (Crustacea: Brachyura) in the estuarine and coastal region of the Patos Lagoon, southern Brazil
ABSTRACT: The abundance and distribution of larval phases of the Portunidae found in the estuary of the Patos Lagoon and the coastal region were studied during two years (1995 and 1999). A conical net (165 cm long, 60 cm mouth, and 330 µm mesh) equipped with a flowmeter was towed for three minutes at 2 knots at six stations within the estuary and four stati
