1 Most studies of salt marsh plant zonation have been at middle to high latitudes the northern hemisphere, in euhaline or periodically hypersaline marshes with regular tides. In this study, we examined an irregularly flooded southern Brazil. Pore water characteristics were compared four vegetation zones across a elevation gradient. Reciprocal transplants between and removal experiments performed examine species interactions low mid marshes. 2 There was no distinctive gradient physical stress...
Three sampling stations located in the inner Patos Lagoon estuary, lagoon's mouth and adjacent coastal beach were visited monthly from end of 1992 until 2014. The are close proximity, but distributed along saline hydrological gradients had never previously been analysed together. Our main questions were: (1) Are monthly, seasonal interannual variations chlorophyll a (Chl a) similar for three stations? (2) Is there any type connectivity among sites? (3) What forces responsible controlling...

In southern Brazil, salt occupy 70 km
Turfeiras topotróficas caracterizam-se como corpos de águas rasas, permanente ou periodicamente alagados por água do lençol freático, percolada através solo inorgânico das terras altas adjacentes à depressão central da turfeira. Possuem solos orgânicos e a cobertura vegetal é dominanda fanerógamas aquáticas emergentes. Este estudo visou o levantamento diversidade específica caracterização principais formações vegetais ao longo duas transecções 200m em uma turfeira topotrófica na localidade...
The Peruvian "anchovy" (Engraulis ringens) maintains the world's largest single species fishery in world. Acoustic data from research cruises surveying distribution area of this provide meaningful information about its behavior and as well abundance within years decades. gathered during 15 (15 summer 12 winter "Pelagic Hydroacoustic Evaluation Cruises") along coast 2000 to 2014, revealed characteristic patterns aggregation anchovy. Measuring pelagic fish for stock assessment were main...
Saltmarshes in Patos Lagoon Estuary have been converted since XIX century due to urban, port and industrial expansion, however the last 53 years losses of saltmarshes were caused mainly by natural process (erosion). Biological ecological processes modified anthropogenic activities, so this study aimed identify quantify (grazing, fire, harvesting, litter, embankments, man-made channels) disturbances (erosion) on saltmarshes. Anthropogenic erosion quantified intensity spatial extension,...
As marismas no estuário da Lagoa dos Patos vem sendo suprimidas desde o século XIX pela expansão urbana, portuária e industrial, entretanto, nos últimos 53 anos perdas de área foram causadas principalmente por processo natural (erosão).As atividades antrópicas entorno das
This study described the myliobatids caught in artisanal beach seine fisheries southern Brazil. Fieldwork was carried out from spring 2012 to winter 2014 Cassino Beach (Rio Grande, Brazil). Both retained and discarded specimens were identified species level, sex, maturity disc width (DW cm) recorded. A total 359 of Myliobatis spp. recorded, which 43.4% fishery discards, 31.5% 25.1% drifting gill-net (‘lance de praia’, a that has developed recently area). Catches higher autumn. 94 goodei (24...
As marismas são ecossistemas entremarés predominantes na costa brasileira em latitudes maiores que29º S. No estuário da Lagoa dos Patos (RS), 6.837 ha de margens e ilhas recobertos por marismasque vêm sendo utilizadas pela atividade agrícola pecuária extensiva desde o século XVII. Este estudovisou caracterizar os usos das pelas atividades econômicas tradicionais (agricultura pecuáriaextensiva) desenvolvidas no Patos. O trabalho foi efetuado nos municípios deRio Grande São José do Norte meio...
Nebulosas Planetárias são objetos extremamente importantes por enriquecerem o meio interestelar com diversos elementos produzidos sua nucleossíntese, e contribuírem a evolução química das galáxias. Com isso, temos formação de moléculas Hidrocarbonetos Aromáticos Policíclicos (PAHs), que as orgânicas mais abundantes no espaço em ambientes astrofísicos relacionados gás, poeira iluminação fótons ultravioleta, detalhadamente estudadas pelo seu grande potencial para formar prebióticas. Neste...
The identification and mapping of coastal environmental units that compose the Lagoa dos Patos Estuary are first steps towards to management. This study was carried out in a preservation area Rio Grande Port. Using photo interpretation four main unit were identified. Salt marshes most representative mainly composed by mid high zone. second represented dunes foredunes, stabilized transitional dune-grasslands. A third identified grassland colonize transition between areas marsh. Disturbed...
RESUMO As gramas halófitas Spartina alterniflora e densiflora são espécies bioengenheiras, que podem ser utilizadas para mitigação de áreas degradadas marismas manguezais, o controle da erosão costeira estabilização dragado depositado em regiões estuarinas costeiras. O objetivo deste trabalho foi avaliar os efeitos densidade plantio adubação com nitrogênio (N) fósforo (P) sobre mudas propagação vegetativa destas duas espécies, crescendo bandejas (0,15 m2; 7500 cm3). Para isto, foram...
