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”.

SETAC SciCon: Spotlight on our presentations (Part 3)
Our research at University of Koblenz-Landau is going virtual at SETAC SciCon! In this three-part blog series, we highlight several poster and platform presentations of our researchers: Today, find out what Ralf. B. Schäfer, Alexander Feckler, and Eric Bollinger have planned for the conference.

In this post, Jochen Zubrod reports on their recently published paper “Is Hyalella azteca a suitable model leaf-shredding benthic crustacean for testing the toxicity of sediment-associated metals in Europe?”.
Continue readingThings are not always as they seem – hidden herbicide effects in periphyton
In this post, Alexander Feckler talks about their recently published paper “Blinded by the light: increased chlorophyll fluorescence of herbicide-exposed periphyton masks unfavorable structural responses during exposure and recovery”.
On the insignificance of significance
In this post, Alexander Feckler talks about their recently published paper “When significance becomes insignificant: effect sizes and their uncertainties in Bayesian and frequentist frameworks as an alternative approach when analyzing ecotoxicological data”.
Exposure history-dependent effects on ecosystem functioning in streams
In this post, Alexander Feckler talks about their recently published paper “History matters: heterotrophic microbial community structure and function adapt to multiple stressors”.
Midsummer science
I am Jacob, 21 years old, and I just completed 3 semesters of studying Environmental Sciences in Landau. The moment when Mirco Bundschuh offered me to come to Sweden and work on his new and interesting project I knew I want to pause one semester to not miss this opportunity. Packed with 3 cooling boxes filled with frozen leaf material, I flew over to Sweden into my first adventurous internship abroad, which should become an exciting time to keep in mind.
