The evolutionary canary in the coal mine

In this post Executive Editor Marc Cadotte discusses a paper he recently handled by François Keck and colleagues ‘Linking phylogenetic similarity and pollution sensitivity to develop ecological assessment methods: a test with river diatoms‘ Like canaries in coal mines, species can provide important information about deteriorating environmental conditions. A whole sub-discipline of environmental biomonitoring has emerged to provide the necessary tools to evaluate biological responses … Continue reading The evolutionary canary in the coal mine

Defining a successful river restoration project

In this post Associate Editor Tadeu Siqueira discusses a paper he recently handled by Daniel Hering and colleagues ‘Contrasting the roles of section length and instream habitat enhancement for river restoration success: a field study of 20 European restoration projects’ Streams and rivers are among the most degraded ecosystems in the world. In comparison to oceans, these ecosystems contain a tiny portion of the total … Continue reading Defining a successful river restoration project

Managing native fish with environmental flows

Flow alteration is one of the most common threats to rivers and streams around the world. Alterations such as weirs, dams and water withdrawal for human uses tend to suppress natural flow variation causing a disconnection between rivers and floodplain wetlands. These changes to the natural hydrology of rivers can have detrimental effects for fish communities because many species of fish rely on periodic access to … Continue reading Managing native fish with environmental flows

Protecting freshwaters from forest harvesting

Most of us depend on paper, packaging, building materials and fuel wood. Forestry is an important industry, however, the impacts on freshwaters are immense and over the years forest managers have generally come to leave some trees alongside streams to protect freshwaters, i.e., riparian buffers. A new study by Richardson and Béraud shows that the impacts they are trying to protect against are more different … Continue reading Protecting freshwaters from forest harvesting
