A mesocosm experiment on the effects of hydrocarbon and copper pollution on a sublittoral soft-sediment meiobenthic community
Meiofaunal assemblages in undisturbed box-core samples of sublittoral sediment were subjected to 4 dose levels of pollutants (copper and hydrocarbons) in a mesocosm experiment designed for the GEEP Workshop. Multivariate analyses of species abundance data for nematodes and copepods showed only marqnal differences in species composition between treatments at the end of the experiment, principall...
متن کاملConsequences of increased terrestrial dissolved organic matter and temperature on bacterioplankton community composition during a Baltic Sea mesocosm experiment
Predicted increases in runoff of terrestrial dissolved organic matter (DOM) and sea surface temperatures implicate substantial changes in energy fluxes of coastal marine ecosystems. Despite marine bacteria being critical drivers of marine carbon cycling, knowledge of compositional responses within bacterioplankton communities to such disturbances is strongly limited. Using 16S rRNA gene pyroseq...
متن کاملAssessing sulfate and carbon controls on net methylmercury production in peatlands: An in situ mesocosm approach
The transformation of atmospherically deposited inorganic Hg to the toxic, organic form methylmercury (MeHg) is of serious ecological concern because MeHg accumulates in aquatic biota, including fish. Research has shown that the Hg methylation reaction is dependent on the availability of SO4 (as an electron acceptor) because SO4-reducing bacteria (SRB) mediate the biotic methylation of Hg. Much...

Algae-Based Biofilm Productivity and Treatment of Dairy Wastewater: Effects of Temperature and Organic Carbon Concentration
متن کاملAlgae-based biofilm productivity utilizing dairy wastewater: effects of temperature and organic carbon concentration
BACKGROUND Biofilm-based microalgal growth was determined as functions of organic chemical loading and water temperature utilizing dairy wastewater from a full-scale dairy farm. The dairy industry is a significant source of wastewater worldwide that could provide an inexpensive and nutrient rich feedstock for the cultivation of algae biomass for use in downstream processing of animal feed and a...
