Submerged macrophyte biodiversity buffers impact of eutrophication stress on ecosystem functioning

Biodiversity conservation aims to preserve the ecosystem functions embedded in different species. The positive relationship between biodiversity and ecosystem functioning (BEF) has been proven in experiments. However, the ...

New approach to assess health status of intermittent rivers

More than 50% of the world's river network is made of temporary or intermittent rivers: these are rivers that, during a certain time of the year, mainly summer, present dry riverbeds or some isolated ponds. These rivers show ...

Are new antiseptics safer than their antimicrobial predecessors?

A new study in Environmental Toxicology and Chemistry has found that substances used in antiseptics that replaced high-use antimicrobials appear to have little to no adverse effects at concentrations found in the environment.

Riparian areas could act as climatic refugia for plant diversity

The Lancang River is internationally known for its rich water resources and diverse aquatic ecology, but research on riparian plant biodiversity is sparse. As a tropical transition area in the Mekong Basin, Xishuangbanna ...

Report says native fish overlooked as invaders in US waters

Rivers split across mountaintops and other geographic barriers may flow only a few miles from one another, but to the aquatic creatures in those waters, the separation could represent millions of years of evolutionary time. ...
