Causes of ecological degradation in waterways
Human activities can have a multitude of different effects on rivers and streams, and it is difficult identify those that have the biggest impact on aquatic populations. A newly developed method for assessing ecological degradation in waterways helps deal with this problem and could provide crucial information for water managers charged with tackling the root causes of degradation.

Psychological tests suggested that they had not adapted to the noise over the years, and they did not become less affected with time.

A bleak future for Mediterranean coral as oceans become more acidic
Mediterranean red coral (Corallium rubrum), already endangered due to over-harvesting, is likely to suffer still further under increasing ocean acidification as a result of rising CO2 emissions. Research has shown that under more acidic conditions the structural development of red coral skeletons is abnormal and growth rate is reduced.

Plastics can concentrate toxic pollutants, endangering marine ecosystems
Plastic debris is a serious environmental concern, as a physical pollutant as well as a chemical pollutant when it breaks down in the marine environment. A new study has now shown that plastics can also concentrate other pollutants, with significantly higher concentrations of toxic pollutants adhering to soft, rubbery plastics, rather than hard, glassy plastics.
