National Representatives

The officers of the Executive Board and national representatives of the International Committee were elected by majority and are entrusted with the effective operation of SIL. We encourage your inquiries and concerns to the General Secretary or to your National Representative for consideration and evaluation. Your participation, opinions, and constructive suggestions are important for improvement of the operation and capacities of SIL.

See the List of National Representatives for names and addresses for specific countries.

29th Congress in Finland

The 29th Congress of SIL will be held in the Helsinki University Lahti Research and Training Centre, slightly north of Helsinki on 8-15 August 2004. An extensive itinerary is being organized in this limnological mecca.

30th Congress in Canada

The 30th Congress of SIL will be held in Montreal, Québec, Canada, in August 2007. An extensive series of scientific excursions are being planned to evaluate numerous limnological venues and activities of this region of Canada.

Call for nominations for the Naumann-Thienemann Medal Awards

A detailed summary of the contributions of Einar Naumann and August Thienemann to limnology and the foundation of SIL was presented in the lead article of SILNEWS 21. The Naumann-Thienemann Medal is the highest honor awarded for scientific contributions in international limnology. The Naumann-Thienemann Medal Committee solicits documented nominations of scientists with unusual contributions to the development and advancement of limnology. To nominate a candidate, a complete curriculum vitae, list of publications, and a statement of the outstanding merits of the individual should be submitted to General Secretary Wetzel or President Likens for distribution to and evaluation by the Committee.

Nominations for the Baldi Memorial Lecturer

The Baldi Memorial Lecturer, described in detail in SILNEWS 24 in 1998, for the 29th Congress in Finland will be Dr. Wolfgang Junk, leader of the Tropenökologie Arbeitsgruppe of the Max-Planck-Institut für Limnologie, Plön. The Baldi Memorial Lecturer Committee solicits documented nominations of limnologists that would present seminal insights on a particular subject in inland aquatic ecology. Forward documented nominations to General Secretary Wetzel.

Nominations for the Kilham Memorial Lecturer

The Kilham Memorial Lecture for the 29th Congress in Finland will be Dr. Dag Hessen of the University of Oslo, Norway. The Kilham Memorial Lecture Committee requests documented nominations of limnologists appropriate for this honor. Forward documentation to Gen. Secretary Wetzel for the Committee.

Tonolli Memorial Awards

The Tonolli Memorial Fund for Furthering Limnology in Developing Countries has adequate funding from the interest of the endowment and from contributions to award a few scholarships to assist the research training of young scientists from developing countries. Applications should include detailed documentation of candidates, using a form available from the General Secretary, and letters of recommendation. Submissions should be made to General Secretary Wetzel for distribution to and evaluation by the Committee. The Committee evaluates proposals twice annually, in January and July.

Proceedings Volume 27 (Dublin Congress)

The massive Proceedings of the 27th Congress held in Dublin, Ireland have been published in seven parts (4300 pages). The problems underlying the most unfortunate delays have occurred in issuing this tome have been corrected. Many actions have been taken to prevent recurrence of this unfortunate situation in future congresses.

Proceedings Volume 27 (Melbourne Congress)

By the time this Annual Circular is received by members, the Proceedings of the 28th Congress held in Melbourne, Australia were issued within 18 months following the Congress. The four-part volume has been issued in separate parts to members requesting printed copies. About 20% of SIL members have chosen to receive the entire volume on a single CD-ROM.

SIL Publication Index

The author and subject index of all SIL publications (Verhandlungen 1-20; Mitteilungen 1-21) continues to be well received. This valuable access source to the thousands of SIL publications is available to members at cost of production. Remit SFr 20 or US$10 to the General Secretary-Treasurer for your copy. Remittance in US dollars being sent from foreign countries must be drawn on an international bank in the USA that is recognized by the Federal Reserve System. Certain credit card payments are accepted (see payment instructions here). We are gradually evolving to have all the SIL publications converted to electronic form and available to members digitally.

Limnology in Developing Countries

The first volume of a special book series Limnology in Developing Countries, edited by B. Gopal and R. G. Wetzel, included reviews of limnology for Bangladesh, Pakistan, Malaysia, Papua New Guinea, Sri Lanka, Ghana, and Tunisia. Volume 1 was completed in late 1995 and distributed to all members in good standing. Volume II, edited by R. G. Wetzel and B. Gopal, was distributed in 1999, and it included reviews of limnology of Indonesia, Morocco, Ethiopia, Costa Rica, and Uruguay. Volume III appeared in 2001 and included reviews of limnology in Algeria, Belize, Columbia, and Malawi.

Volume IV is in final stages of completion and will include detailed treatment of the limnology of India, Mexico, and possibly China. Further volumes are currently being completed. These publications are free to members in good standing. They are available for purchase by non-members at very nominal rates indicated through the office of the General Secretary-Treasurer.

The SIL newsletter, initiated in late 1987, is distributed three times annually to all members. SILNEWS 38 will be sent from Canada to all members in December. Our newsletter editor, Dr. Richard Robarts, requests your participation and submission of information to further increase communication and exchange among our members. Forward any information for consideration to Dr. Richard Robarts or Ms. Clara Fabbro, National Water Research Institute, Environment Canada, 11 Innovation Blvd., Saskatoon, Saskatchewan, S7N 3H5, Canada. E-mail: or

Everyone agrees that the SIL newsletter is informative and an essential vehicle for exchange among SIL members between our triennial congresses. The escalating costs printing and especially mailing the SILNEWS are becoming prohibitive. SILNEWS is already available on the SIL web site immediately when issued. The Executive Board is again evaluating shifting to distribution of the SILNEWS electronically by email.

We have received a number of reactions to providing the SIL NEWS electronically from members. We solicit further opinions from other members on receiving the SIL Newsletter by electronic means only by email attachment. PLEASE VOICE YOUR OPINION TO NEWSLETTER EDITORROBARTS OR GENERAL SECRETARY WETZEL.

Archiv für Hydrobiologie

Ordinary members (Sodales) can obtain this publication, an official journal of the SIL, at a price reduction of 20%. Please send orders to the General Secretary for forwarding to the publisher, E. Schweizerbart’sche Verlagsbuchhandlung. The main Volumes (Hauptbande) of the Archiv für Hydrobiologie are designed for short original works from the entire field of theoretical and applied limnology. Complete and critical reviews of individual subjects of limnology appear as the “Ergebnisse der Limnologie” (Advances in Limnology).

Sponsor a member

Some members have generously contributed sufficient funds to sponsor a researcher or student of limnology from developing or other countries from which it is difficult to pay our modest membership fee. Alternatively we urge you to contribute to the Endowment Fund.

Library Affiliates

SIL has shipped excess copies of all available past SIL publications to a number of libraries of developing or other countries in which it is difficult for institutional membership. In addition, institutional memberships have been provided for certain libraries from our Endowment Fund. We welcome applications from institutional libraries for assistance with their membership. Direct inquiries to the office of the General Secretary and Treasurer. Persons knowing of particularly deserving institutional libraries are urged to inform us – we are attempting to have our scientific contributions reach as many workers as possible.

Increase our membership!

In order to enhance the many roles of our membership in international limnology, particularly in education, research, and effective management of water resources, we need to increase our membership to include greater representation of active freshwater scientists and water resource managers. It is particularly appropriate and important that young researchers and students become involved in the activities of SIL. The Student Membership for fulltime students working toward a graduate degree is being used widely. Students receive a 50% reduction in annual fees for a maximum of three years.
