Contact National Representatives

Countries with ten or more SIL members are entitled to elect a National Representative (NR). NRs are elected for three-year periods. They assist the General secretary-Treasurer in collecting annual dues from members of their country in their own currency and transferring the total amount to SIL’s bank account.

Richard Johnson

Professor of Environmental Assessment, Biodiversity at the Swedish University of Agricultural Sciences

My research interests are largely focused on understanding the importance of local and large-scale drivers of the biodiversity of lakes and streams, and how human intervention alters these patterns. Recent research interests include the importance of cross-habitat linkages for biodiversity, ecosystem functioning and resilience.

As a SIL national representative, I endeavour to spread knowledge of inland aquatic systems and their management to stakeholders and encourage young professionals to join SIL’s mission.

Pieter Spaak

Head of the department Aquatic Ecology at Eawag, the Swiss Federal Institute of Aquatic Science and Technology.

My main research focus is on the processes that influence the diversity in freshwater plankton populations. As main model system I use Daphnia. We study for example the influence of cyanobacteria on Daphnia populations and their parasites. Recently we sequenced the genome of Daphnia galeata.

I see SIL, with its broad representation from countries all over the world, as the ideal organisation to support international collaboration among limnologists. As Swiss SIL representative I want to continue what I do in my work: integrate science and practice. Water is a very valuable good which is under threat even in Switzerland, as witnessed by ongoing discussions on, for instance, micropollutants or whether lakes are now "too clean." With my contacts within Switzerland and abroad I hope to connect colleagues in such discussions.
