AMEO experience – nEcoTox, Germany – Veronica Rodriguez and Lorenz Witt (2023)

In this blogpost, Veronica Rodriguez and Lorenz Witt share their internship experience at nEcoTox, Germany. Students of the  Environmental Pollution Management (Ecotoxicology)  Program complete an 8-week internship each year, the so-called “AMEO”. The AMEO is performed either at an external university, governmental or industrial research institute  where students learn to apply the competences achieved during their study. Students also use this opportunity to travel and explore Germany.

Does global warming lead to taxonomical and functional reorganization of insect communities in European rivers?

In this blogpost, Dr. Alessandro Manfrin, postdoc of the DFG RTG SystemLink,  talks about his recent study published “Taxonomic and functional reorganization in Central European stream macroinvertebrate communities over 25 years”. Here they observed that because of increasing temperatures, species that favour cold waters are progressively replaced by those that favour warm temperatures leading to functional alterations of the community.

Can heterogeneous landscapes mitigate pesticide stress?

In this blogpost, Moritz Link reports how pesticide toxicity affects stream ecosystems in Transylvania, Romania, a region where traditional agriculture prevails. The researchers analyzed macroinvertebrate communities, leaf litter decomposition and parasite prevalence in relation to physico-chemical stressors in the stream and the landscape.

How will insecticides affect streams under climate change?

How climate change will alter the effects of toxicants is a key concern in the 21st Century. Rising water temperature can increase the toxicity of some contaminants to stream-dwelling animals in laboratory conditions, as has been shown for the most widely used insecticides in the world – the neonicotinoids. But until this study, whether this translates to more realistic environmental scenarios remained to be tested. In this blogpost, Sam Macaulay talks about his mesocosm experiment studying the effects of rising water temperatures and neonicotinoids on stream invertebrate communities.
