How River Macroinvertebrates Across Europe Respond to Common Pollutants

Figure 1: Stream sampling sites for macroinvertebrates across Europe.

Today, Dr Jonathan Jupke tells us about his latest publication, where he and his colleagues explored how river macroinvertebrates across Europe respond to common pollutants, such as copper and imidacloprid, and what these findings mean for environmental risk assessment.

How algae and fungi team up to nourish aquatic invertebrates

In this blog post, Alexander Feckler and his colleagues explore the role of autochthonous primary production for the quality of microbially-colonized leaf material as food in heterotrophic food web in headwater streams. Despite reduced autochthonous primary production in shaded headwater streams, this study indicated a potential for enhanced secondary production and energy transfer to higher trophic levels within the aquatic ecosystem due to so-called “algal priming”.
