The Patos Lagoon estuary is a microtidal system that is strongly regulated by atmospheric forces, including remote large-scale phenomena such as the El Niño Southern Oscillation (ENSO), which affects precipitation ...

Information about bacterial community structure and functioning in fish farming ponds remains scarce, mainly due to methodological difficulties in counting and identifying uncultured bacteria. The main objective of ...

A field study of the microbial food web was conducted in a shallow region of the Patos Lagoon estuary (32°07′S; 52°06′W) between March 1989 and March 1990. On average, bacterial biomass (mainly attached bacteria) constituted ...

O presente estudo teve por objetivo propor uma base de informações que visa nortear o planejamento para a elaboração de um novo Plano de Desenvolvimento e Zoneamento (PDZ) para o Porto de Pelotas/RS, calcado nas suas ...

In situ benthic flux chamber experiments were performed during late austral spring and early summer of 1996 at eleven nearshore locations in the southern Patos Lagoon, Brazil. The Patos Lagoon is the largest lagoonal system ...

O objetivo deste trabalho foi avaliar a eficácia da benzocaína e do eugenol como anestésicos para juvenis de Trachinotus marginatus. Foram testadas concentrações de 25, 50, 75, 100 e 150ppm de benzocaína e de 25, 37,5, 50, ...

Os trabalhos desenvolvidos nesta dissertação visam elaborar subsídios que possam contribuir para o melhor desenvolvimento do cultivo do camarão-rosa Farfantepenaeus paulensis em cultivos alternativos no estuário da Lagoa ...

Ecologists, particularly those engaged in biogeomorphic studies, often seek to connect data from three or more domains. Using three-block partial least squares regression, we present a procedure to quantify and define ...

Age determination using quantification of in situ neurolipofuscin has been an useful and reliable tool to understand population dynamics of crustaceans. In the present investigation, in situ neurolipofuscin was quantified ...

Initially, the heart concentration data does not seem relevant for use as a bioindicator, mainly due to its low concentration level. After applying a normalizing procedure, the heart results were a better Hg bioindicator ...

The current study aimed to evaluate the influence of lipoic acid (LA) supplementation (439.84 ± 6.71 mg LA/kg feed) on antioxidants responses throughout the time in intestine, liver and muscle of juvenile common carp Cyprinus ...

Background: Toxic cyanobacterial blooms are recurrent in Patos Lagoon, in southern Brazil. Among cyanotoxins, [D-Leu1 ] microcystin-LR is the predominant variant whose natural cycle involves water and sediment ...

Biological degradation of cyanobacterial hepatotoxin microcystins in estuarine and coastal water samples from the Patos Lagoon estuarine system, a coastal lagoon situated at the southernmost region of Brazil, was observed. ...

Nanotechnology has been proven to be increasingly compatible with pharmacological and biomedical applications. Therefore, we evaluated the biological interactions of single-wall carbon nanotubes functionalized with polyethylene ...

The effect of biofilm was assayed for Farfantepenaeus brasiliensis postlarvae fed with commercial pellets. Indoor tanks in a zero water exchange system were used, considering: shrimp fed with biofilm and commercial feed ...

This note reports the first occurrence of golden mussel Limnoperna fortunei (Dunker, 1857) colonizing (biofouling) the surface body of the anomuran crab Aegla platensis Schmitt, 1942 on the São Gonçalo channel, Mirim ...

The southern portion of the Brazilian coast is dominated by coastal lagoons formed by sandy barrier spits with small inlets. This coastal configuration is a barrier to the surface flow of freshwater to the sea; thus, we ...

Uma população do caranguejo violinista Uca rapax proveniente de manguezal degradada do estuário do Rio Paraty, RJ, Brasil, foi estudada quanto à aspectos populacionais durante o período de um ano (Julho/2001 a Junho/2002). ...
