36th SIL Congress, Berlin, Germany (7-10 August 2022)
SIL 100 – the centennial and 36th Congress of SIL –held in Berlin, Germany, from 7 to 10 August 2022, was a great success. Participants entered into personal exchange, the atmosphere was stimulating, facilitated by the positive spirit of the participants, the high quality of contributions in the individual scientific sessions, and interesting presentations by the seven plenary speakers, including the Baldi and Kilham lecturers. Importantly, there was a good mix of age groups. More than a third of the registered participants were early career scientists, suggesting the society is rejuvenating. Considering the ongoing constraints imposed by the COVID-19 pandemic and the war in Ukraine, the number of onsite registrations greatly exceeded expectations. Unfortunately, however, various countries where limnology is traditionally well-developed were less well represented and there were also late cancellations by delegates due to visa issues and travel restrictions.
Several new aspects were introduced at SIL100, which contributed to the success of the Congress. In particular, the scientific program, developed by the limnological community, was entirely bottom up. Instead of predefined topics, all sessions built on ideas submitted by session conveners. This resulted in a total of 41 sessions spanning a variety of themes that covered curiosity-driven fundamental limnological research as much as practical issues relating to urgently needed advice on the protection and management of freshwaters.
SIL 100 in Berlin was organized as a Hybrid Congress. A total of 626 scientists from 49 countries attended the Congress, not including exhibitors, guests, accompanying persons, and others. This number greatly exceeded the expectations that we had in view of the restrictions and uncertainties related to the COVID-19 pandemic and the ongoing war in Ukraine. Conversely, online attendees were fewer than expected, totaling 230 registrations, which may reflect not only the great interest in direct personal interactions after nearly two years of isolation during the COVID pandemic, but also that online participation is still not considered a satisfactory alternative. More than one third of the participants were early career scientists, indicating their strong interest to participate in person.
Congress co-chairs: Rita Adrian, Mark Gessner, Lars Tranvik

35th SIL Congress, Gwangju, Republic of Korea (22-27 August 2021)
The XXXV SIL Congress was held in Gwangju, Republic of Korea from 22 – 27 August 2018.
The 35th Congress of the International Society of Limnology AUGUST 22-27, 2021 held in Gwangju, Republic of Korea was a great success! Its theme Biodiversity and Ecosystem Services for Healthy Rivers, Lakes and Humans drew over 500 people from more than 50 countries. Over 100 students and early career researchers participated in on-line courses and over 50 students had inspiring brain dates with Eminent Scholars. On-line Working Group meetings also saw a healthy participation of members. Keeping with SIL’s mission to encourage and train students and early career researchers, 32 students acted as co-chairs for the various sessions of the congress, giving them precious hands-on experience both in scientific discussion and the workings of a scientific meeting.

33rd SIL Congress, Torino (31 July – 5 August 2016)
Our Society is an international non‐profit organization dedicated to advancing limnology for the benefit of all. It is with this principle in mind that the congress co‐chairs Cristiana Callieri, Luigi Naselli‐Flores and myself started organizing the 33rd SIL Congress with the goal of producing a scientifically relevant event, taking into account the interdisciplinary nature of limnology, promoting a large attendance of colleagues (in particular of young scientists), and ensuring the self sufficiency of the congress. We kept the registration fees as low as possible, and we put a lot of effort in the preparation of the program and the conference logistics. We also tried to ensure the best use of revenues from subscriptions, reducing as much as possible unnecessary expenses and seeking additional funds, to offer participants extra benefits tuned to possible additional revenues.
The congress statistics let us believe we achieved the goal. This belief was supported by the 816 participants from 58 countries coming to Torino, thanks to the appealing program but also to the low registration fees, at least 1/3 lower than in previous congresses. 36% of attendants were students or colleagues early in career, facilitated by the low registration fees (200 and 250 € for members and non‐SIL members, respectively). The interest in limnology was confirmed by the participation of numerous non‐SIL members (58%). This suggests that there is room for the further growth and development of SIL.
The appeal of the plenary lectures and the speakers, listed below, certainly contributed to achieving the objective:
Coaxing lakes to conduct experiments: palaeolimnology and the acid rain debate.
Baldi Memorial Lecture, Rick Battarbee
Ecological isolation despite physical connectedness: evolution‐dependent species richness in large and deep lakes.
Kilham Memorial Lecture, Ole Seehausen.
Histories of cyanobacteria from a northern country: redefining limnological “nordicity”.
Frances R. Pick
Climate change and stoichiometric implications for zooplankton.
Challenges and opportunities for research and management in Mediterranean‐climate rivers.
Limnology in the 21st century: incorporating data‐intensive research, open science, and team science to address broad‐scale problems.
Kendra Spence Cheruvelil
Biodiversity and ecosystem functioning in miniature worlds.
Climate change and multiple stressors in agricultural streams.
Winner of SIL Students Competition, Jeremy J. Piggott
A novelty of this conference was the kick‐off plenary lecture, held by Professor Christian Greco, Director of the Egyptian Museum in Torino with the title: Water management in Theban archaeology. It was not on a limnological subject sensu stricto, but it aroused the interest of all because the lecture addressed the issue of traditional water use in ancient Egypt and the technical theme of the problems caused to the conservation of Egyptians archaeological sites by the modern water use.
The second novelty of Torino SIL 2016 was the plenary lecture given by the winner of SIL Students Competition. SIL successfully introduced this competition to enhance the presence of young researchers in the association. We also had a chance to ask the winner, Jeremy Pigott, to present during the closing ceremony his view on SIL and the Congress.
In spite of the difficult economic situation (only 4% of the total budget were from sponsors), we obtained good support for students and some in‐kind sponsorship very welcomed by participants (for instance free ice cream and beer). It was also possible to offer an Occitan music concert at the Congress Opening Ceremony, which was well met by the participants.
We rented a comfortable conference venue (Lingotto Congress Center) and an effective audiovisual management system. The 10 parallel sessions during the 4 days of the conference have worked well, without loss of time due to technical problems.
The SIL Congress had a significant relevance in the Italian media. The three major national newspapers devoted space to the event and published articles on topics related to ecology of inland waters during the Congress days. Even the radio channels and the national and regional TV channels interviewed the organizers and the participants, and broadcasted services on the Congress.
During the Congress there was a national round table, which involved numerous water managing public bodies (summary at http://www.silitaly.it).
Finally, the 33rd SIL Congress was rewarded with a surprise arriving a few days after the Congress ended. This has bridged a little, at least emotionally, the gap of the absence of public funding. The President of the Italian Republic Sergio Mattarella offered a commemorative plaque in bronze in recognition of the international relevance of the 33rd SIL Congress.

32nd SIL Congress, Budapest (4-9 August 2013)
The 32nd triennial SIL Congress entitled “Diverse water – Rich life” turned out to be a great success. For five days, from 4th and 9th August 2013, some 460 scientists from 47 countries gathered together at Budapest. The daily deliberations were preceded by plenary talks on subjects of general importance and changing significance. The participants demonstrated the importance of understanding the problems related to different aspects of inland waters.
The scientific program was a rich mix of scientific formats, ranging from memorial lectures, to plenary speeches featuring famous speakers and thought-provoking topics. The Baldi Memorial Lecture was given by Robert J. Naiman from the School of Aquatic and Fishery Sciences, University of Washington and Centre of Excellence in Natural Resource Management, USA, University of Western Australia, Australia with the title “Complexity and the Restoration of River Ecosystems”. The Kilham Memorial Lecture by Cathrine M. Pringle from the Odum School of Ecology, University of Georgia, USA was titled “How resilient are neotropical stream ecosystems to species loss and climate change?”.
The authors of plenary presenters are outstanding limnologists
- John A. Downing (Association for the Sciences of Limnology & Oceanography; Department of Ecology, Evolution and Organismal Biology, Iowa State University), with the following title: “Limnology and Oceanography: two estranged twins reunited by global change”.
- Martin Dokulil (Institute for Limnology, University Innsbruck), with the title: “Impact of climate warming on European inland waters”.
- László Somlyódy (Department for Sanitary and Environmental Engineering, Budapest University of Technology and Economics). The title of his talk was “Eutrophication and water level variability of shallow lake Balaton: Evaluation of risks and trade-offs”.
- Henri Dumont (Ghent University), talked on “Limnology meets Marine Biology in West Eurasia’s brackish water lakes”.
- Luigi Naselli Flores (Department of Biological, Chemical and Pharmaceutical Sciences and Technologies, Universita degli Studi di Palermo) with the following title: “Morphological analysis of phytoplankton as a tool to assess ecological state of aquatic ecosystems”.
In addition to these lectures, the scientific program comprised 287 oral and 117 poster presentations. Sessions were all held under one roof in the exquisite Budapest Congress Centre, where we had numerous lecture rooms reserved daily for 8 parallel sessions covering the 22 topics of the congress, ranging from molecular biology and biodiversity to biogeochemical cycles and limnology at global scales.
In addition to the scientific program, we successfully organised several mid-congress excursions. Hungary abounds in sites and attractions to visit, whether you prefer to visit historical landmarks and natural phenomena, or you are more interested in special activities like fishing, thermal spas or horse-riding. Our visitors had the opportunity to see natural submontane streams typical of Hungary, small (Ipoly) and large (Danube) rivers and the largest shallow lake of Central Europe, Lake Balaton.
The Congress Dinner on the 8th of August was held in the rolling hills of the Domony Valley, about 50 km from Budapest, where all services selected for our entertainment were provided successfully. At the site we found not only beautiful scenery, but also enjoyed a sumptuous dinner with typical Hungarian dishes, drinks and music. After dinner when it had become dark, a popular equestrian show entertained us all for more than an hour.
The congress also enabled participants to build and strengthen networks, allowed them to share and exchange information. This will help the congress delegates to utilise the acquired knowledge in furthering our understanding of inland waters. During the Student Forums young scientists had the possibility to talk face-to-face with well-known limnologists and board members of the SIL.
The best oral presentation of a scientist under the age of 35 was won by Stephanie Palmer (Canada) with her presentation in the “Remote sensing and GIS in limnology” session entitled: “Evaluation of MERIS chlorophyll-a retrievals and time series for Lake Balaton, Hungary”. The best poster presentation of a scientist under the age of 35 was won by Pavel Svoboda (Czech Republic) presented in the “Ecology of the Benthos” session entitled: “Relative contribution of neutral and niche-based processes to desmids communities at a local spatial scale”.

31st SIL Congress, Cape Town, South Africa
Following a formal bid to host the congress in 2001 during the 28th congress in Melbourne and partial acceptance in 2004 at the 29th congress in Lahti, it was awarded to South Africa in 2007 at the 30th congress in Montreal. Unfortunately several of the initial lobbyists retired or moved to greener pastures, which meant that only a handful of us drove the process. The Local Organizing Committee (LOC) consisted of: Johan Grobbelaar (chairperson), Brian Allanson (convenor of the scientific committee), Mike Silberbauer (IT and logistics coordinator), Carin van Ginkel and Jenny Day.
The University of the Free State provided assistance with the finances, book keeping, web space, IT, local marketing and some administrative support. Post graduate students and staff from the University of Cape Town helped with the registration and excursions, while Sue Allanson, Mercia Grobbelaar, Anita Lombard and Julanda Theron handled the registration and information desk. It is a daunting task to organise a SIL congress, but equipped with a two page “Manual for Organizing a SIL Congress” written by the late Bob Wetzel, fools rush in where angels fear to tread! Some 900 regular mail letters were sent to SIL members and a total of almost 5 000 emails were handled by me alone, which excludes those done by the other LOC members. It required quite a balancing act to marry the venues with the number of delegates, especially since the numbers increased significantly just prior to the deadline for registration and the week following the deadline. We deviated slightly from previous SIL congresses in that the midweek excursion was only a half day and the congress was five, instead of six days. Some statistics and information on the 31st congress are:
- 263 delegates
- 76 students
- 43 accompanying persons
- 43 countries represented
- 6 plenary, the Baldi and Kilham lectures
- 223 oral presentations
- 76 poster presentations
- 5 parallel sessions (for the oral presentations) and 3 poster sessions
- 3 workshops and 1 SIL working group
- The South African Department of Water and Environmental Affairs was our main sponsor
- The venue was the Cape Town International Convention Centre
Pre- and post congress tours were offered and delegates could choose from six mid-congress excursions (the latter included limnological and scientific information). The registration fee covered all costs at the venue, i.e. the welcoming function, teas/coffee, lunches, mid-week excursions, dinner, individually made congress bags, programme, CD with abstracts and a congress T-shirt. We also managed to support each student delegate with US$ 200 to cover the actual costs. Seven prizes were awarded to students at the closing ceremony, following the adjudication by Judit Padisak and her team. Scientifically and socially the congress delivered. There was ample time to meet and discuss issues. The new SIL journal (Inland Waters), declining numbers of SIL members and the problems facing the inland waters of South Africa and many other areas of the world were discussed in depth. Climate change, great lakes, informatics, lipids and the impact of water level fluctuations, were only some of the session topics. The many encouraging emails and praise, are ample reward for organising the congress and we as the 31st Congress LOC, wish the organisers of the 32nd Congress all the best and remember “Come the night, all will be alright”.
