This study investigated the potential of indigenous endophytic bacteria to improve the efficiency of the wetland helophyte Juncus acutus to deal with a mixed pollution consisting of emerging organic contaminants (EOCs) and metals. The beneficial effect of bioaugmentation with selected endophytic bacteria was more prominent in case of high contamination: most of the inoculated plants (especially...

The plankton fauna of the state of Piauí, Northeastern Brazil, especially in the Parnaíba basin, is still poorly known; the results of most studies of the subject have not been published and can only be found in grey literature (unpublished scientific works), such as course completion work and consulting reports. Thus, this paper presents data from samples taken recently from different water bo...

In 2001 and 2002, Georgia salt marshes experienced a dieback event that affected more than 800 ha throughout the coastal zone. The dieback event was unprecedented in the state and affected both Spartina alterniflora and Juncus roemerianus. A transplant study was conducted from May to October 2003 to determine if healthy plants could survive in dieback areas. Transplants were carried out at two ...

The species composition and abundance of the zooplankton community of seven reservoirs of the Paranapanema River, located between 22 degrees 37'-23 degrees 11'S and 48 degrees 55'-50 degrees 32'W, were analysed over four periods, in the year of 1979. The zooplankton community was composed of 76 species of Rotifera, 26 species of Cladocera and 7 species of Copepoda. For a large part of the perio...
