Previous CWE Symposium: Aquatic microbiomes: Impact in man-made and natural ecosystems
28th of June 2019 Netherlands Institute of Ecology, Wageningen
Microbes are at the basis of all life on earth, catalysing all major biogeochemical cycles thereby also providing many ecosystem services. In light of all global challenges and securing a sustainable future for our planet a more comprehensive understanding of the functioning of microbial communities and their interaction with the environment is necessary. Microbiome research, focussing on all microbes (bacteria, archaea, fungi, prozoa) in a particular environment, has gone through a revolution in the past decade - mainly facilitated by comprehensive sequencing technology unlocking diversity and metabolic potential in large numbers of habitats and under various environental conditions. The present CWE symposium aims at bringing together examples of microbiome research in aquatic systems with relevance for biogeochemical cycling, human health, aquaculture, aquatic foodwebs and aquatic plant growth.

Previous CWE Symposium: Future of rivers and streams: ecology and restoration under global change
6 March 2019 University of Antwerp, Belgium
The aquatic environment is a very dynamic and complex metasystem that fulfills a large number of key services. It hosts an enormous diversity of plant and animal species, but is threatened by global change. The sustainable use, management and protection of the aquatic environment in all its diversity, is key to the success of a whole range of human activities and their long term sustainability. This CWE symposium lists present-day threats and opportunities in rivers, makes projections for the future and learns about 21st century river management.

Previous CWE Symposium: Towards renewable energy: opportunities and consequences for freshwater and marine ecosystems
29 Juni 2018 Deltares, Delft
Renewable energy sources such as solar panels, geothermal energy and wind turbines are increasingly replacing fossil fuels. Freshwater and marine ecosystems provide many opportunities for generating renewable energy, however, this may come with ecological consequences. This CWE symposium brings together research on both the opportunities and consequences of the current energy transition for freshwater and marine ecosystems.
Gerben van Geest and Pascal Boderie (Deltares): The impact of cold water release on ditch ecosystems.
Previous CWE Symposium: Future of aquatic carbon: impacts, feedbacks and mitigation
17 November 2017 Netherlands Institute of Ecology
The global carbon cycle is changing at an unprecedented rate, with a wide range of consequences for aquatic ecosystems. For instance, primary producers may benefit from higher levels of CO2 while ocean acidification may hamper calcification in marine organisms. Furthermore, changes in wetland functioning may feedback on global carbon cycling with shifts in greenhouse gas emissions accelerating or buffering climate change. This CWE symposium brings together research on different components of the carbon cycle in both inland and marine systems, aiming to present a comprehensive overview on the future of carbon in aquatic ecosystems.
Previous CWE Symposium: Multiple stressors and ecological complexity in aquatic systems
23 June 2017 - Leiden University
Realistic predictions of how existing and emerging anthropogenic stressors (e.g. climate change, pesticides and nutrients) affect our natural environment and the organisms therein are essential for targeted ecosystem management. Historically, scientific studies have focused on the effects of single anthropogenic stressors and single ecosystems. However, it is increasingly recognized that multiple anthropogenic stressors can interact and that anthropogenic pressures resonate beyond ecosystem boundaries. This CWE symposium unites research on various stressors and natural complexity, focusing on aquatic ecosystems.
Mirco Bundschuh (SLU, Uppsala): Effects of contaminants across ecosystem boundaries: Concept and experimental design.
Annemarie van Wezel (Utrecht University/KWR): Understanding and mitigating risks of chemicals in (ground)water systems.
Previous CWE Symposium: From Wadden Sea to Marker Wadden: functioning and restoration of large aquatic ecosystems
The Wadden Sea and the IJssel- and Markermeer were once part of the single estuary of the Zuiderzee, but have become units since closure of the Afsluitdijk in 1932. Both ecosystems continue to be of great importance as habitat for aquatic organisms, yet they also face many challenges for the conservation of plants, fish and birds. In this CWE symposium we investigate the main drivers of the functioning of these large marine and freshwater ecosystems and pay ample attention to the many new initiatives to restore and improve the quality of nature from Wadden Sea to Marker Wadden.
Previous CWE Symposium: The good, the bad or a bit of both? The role of exotic species in aquatic ecosystems
Globalization and climate change facilitate the spread of exotic species into our ecosystems. We fear that exotic species will destroy our native ecosystems. However, our feelings towards exotic species are mixed, because sometimes they may play a crucial role in healing our damaged ecosystems. In the upcoming CWE symposium we unravel how exotic plants and animals impact ecosystem functioning, find out whether they coexist or compete with native species and discover their impact on native flora and fauna.

The last CWE symposium, 'Half a century of fundamental and applied wetland ecology: from acidification to climate change', was dedicated to the retirement of Prof. dr. Jan Roelofs.
Wetland ecologists have dealt with many different anthropogenic stressors over the past decades. The fundamental and applied research concerning these stressors has contributed to our knowledge on how wetland ecosystems function. In this symposium, the speakers will talk about drivers of change, important ecosystem processes and options for habitat restoration. Following the regular programme, Prof. dr. Jan Roelofs gave his official farewell lecture after 42 years of ecological research.
Previous CWE Symposium: Growing Peat, 11 June 2015
The symposium on Growing Peat was well visited by an international audience of more than 80 people. We had a full programme with interesting talks and a wonderful lunch excursion to the Volgermeer. The presentations are available as pdf's:
We thank all participants for their contribution to this successful symposium. The next CWE symposium, 'Half a century of fundamental and applied wetland ecology: from acidification to climate change', is dedicated to the retirement of Prof. dr. Jan Roelofs and will be held in Nijmegen at the 27th of November. More information will follow later.
