- ... We analyzed the impact of copper mine tailing discharges on benthic Archaea and Bacteria around the city of Chanaral in northern Chile. Quantitative PCR (Q-PCR) showed that the bacteria dominated the prokaryotic community at both sites, but only the bacteria showed a decrease in abundance in the copper-contaminated site. Q-PCR on reverse transcripts indicated a higher activity of both bacterial an ...

- ... Florida Bay exhibits a natural gradient of strong P limitation in the east which shifts to weak P or even N limitation at the western boundary. This nutrient gradient greatly affects seagrass abundance and productivity across the bay. We assessed the effects of N and P additions on sediment bacterial community structure in relation to the existing nutrient gradient in Florida Bay. Sediment samples ...

- ... Marine sponges are the most primitive metazoan and host symbiotic microorganisms. They are crucial components of the marine ecological system and play an essential role in pelagic processes. Copper pollution is currently a widespread problem and poses a threat to marine organisms. Here, we examined the effects of copper treatment on the composition of the sponge-associated bacterial community and ...
