The ClearDetections team enjoyed their time in Ghent (Belgium) during the 2nd International Symposium on Nematodes as Environmental Indicators (5 – 6 July 2012 at Ghent University). It was the second conference of its kind at an international level, after the success of its predecessor event in June 2007 at Heriot-Watt University, Edinburgh, UK. Many anthropogenic factors have a negative impact on the quality of soil, air and water leading to detrimental environmental changes. This conference brought together experts studying the response of key food web organisms to these changes. Scientists from across the world using a common platform, the phylum Nematoda, presented their studies on these environmentally important organisms to address questions of habitat and ecosystem changes at community, individual organism and molecular levels in terrestrial, freshwater and marine ecosystems.
