Recent decades have witnessed a sharp biodiversity decline in freshwaters due to multiple stressors. The presence of stressors is expected affect community structure and interactions freshwater ecosystems, with subsequent functional consequences. We synthesized the state experimental, manipulative multiple-stressor studies that focused on multispecies assemblages freshwaters. Compared rivers la...

In 2008 the Italian government classified Bussi sul Tirino area (Central Italy) as Site of National Interest destined to remediation which, unfortunately, has not yet begun. The decision followed >20 years illegal dumping industrial wastes, lasting from 1984 2005, that generated biggest toxic waste disposal site in Europe. contamination profile was mainly characterized by PCDD/Fs, PCBs, PAHs, c...

The emergence of antibiotic resistant bacteria in aquatic environment has led to an increase waterborne health risks alarming extent. This study attempts investigate the population certain strains Peninsular Malaysia. From samples 14 rivers from 7 different states Malaysia, a total 203 isolates were successfully isolated. These are Negeri Sembilan, Melaka, Selangor, Kuala Lumpur, Kedah, Kelant...

The influence of water brownification (an increase in color) on floating-leaved macrophytes appears to be an important issue predicting the consequences climate change freshwater ecosystems. To fill gap knowledge this area, we performed a laboratory experiment aiming test impact humic acid (HA) Lemna minor sampled from oxbow lake. Plants were exposed over seven days four different additions pur...

Large herbivores have been described as agents of change in terrestrial habitats. Their effect on aquatic ecosystems are, however, underexplored. We raise the question whether elephants and hippopotamus potential to significantly alter limnological properties and, indirectly, primary secondary productivity within small shallow freshwaters arid semi-arid African landscapes. In this note we discu...
