SIL 2016 Congress (31 July - 5 August 2016)
Torino, Italy


29 October 2015

SIL Student Competition

Thirty one applications from 16 countries were submitted to the SIL student competition by the deadline of 15 October. This includes applicants from Argentina, Australia, Austria, Belgium, Brazil, Finland, Hungary, Ireland, Italy, Mexico, Netherlands, New Zealand, Poland, Spain, UK, and USA. This competition, of the best limnological paper published, coming out of a recent MSc or PhD thesis, was first announced last year has attracted much attention. The winner of this competition will be invited to present his published article in a plenary lecture in the next SIL congress in Torino in August 2016.

By 15 December, each country will have to submit its one or two best candidates to the international competition. Most countries are allowed to send only one national competitor, but countries with > 50 SIL members can send two competitors. So countries with more applicants than allowed have set national committees to elect the one or two applicants that will continue to the international competition. Prof. Judit Padisak will chair the international committee that will choose the competition winners. In March 2016 the competition winners (first three places) will be announced, the awards will be given in Torino.

Updates regarding the competition will be advertised on this page, do check from time to time.

Save Lake Ohrid

Ohrid SOS, a local citizens’ initiative established to protect ancient Lake Ohrid of Macedonia, is appealing to the limnological community for friendship, support, partnership and participation in an exciting new vision to guarantee the future of this lake. At present, a government-backed, mass-tourism urbanization plan may tear apart Lake Ohrid’s precious ecosystem in the name of economic progress.

However, we believe there is another way: Working together with SIL members and educative/scientific institutions, Ohrid SOS would like to unfurl a smorgasbord of courses, research projects and ecological schemes that can fully entwine the environmental integrity of the Lake Ohrid region within a viable economic framework. This would present a meaningful alternative to the mass-tourism model by creating a strategy for sustainable eco-, knowledge and volunteer tourism, and enshrining scientific discovery within the local financial architecture. Nonetheless, it will only be actioned under the condition that Lake Ohrid’s ecological security is ensured by total protection first.

If you would like to help pioneer this vision by establishing research or learning projects in the Lake Ohrid region, or are interested to cooperate in other ways please contact dscar.ohridsos@gmail.com, approach via the Ohrid SOS Facebook page, or refer to our website at https://ohridsos.wordpress.com.

Welcome to PEG 2015 in China

PEG-Working Group on Plankton Ecology, founded in 1974, is among the oldest and most active working groups of SIL. Since its first formal meeting in Olso (1974), PEG has arranged more than 20 meetings including symposia, workshop and training courses. PEG meetings bring together freshwater ecologists working on different aspects of freshwater plankton ecology and offer an open platform for deep discussion and exchange of ideas between plankton ecologists from diverse waters and regions. The next PEG meeting will be held in Guangzhou, China, on 20-24 November, 2015. PEG 2015 will focus on the role of plankton diversity in bloom dynamics. Phytoplankton blooms are on the rise worldwide nowadays, especially in developing countries, adding urgency to the need to understand how blooms form.

Argentina Elects First-Ever SIL National Representative

Argentina has just elected its first-ever SIL National Representative. Dr Inés O’Farrell of the CONICET - University of Buenos Aires was elected for this position. We wish her lots of success!

To have a National Representative, a country has to have at least 10 SIL members. Argentina has increased its membership from only 1 in 2005 to 17 currently. This is the largest number ever of SIL members from Argentina. Another country that now has enough members to elect a National Representative is Mexico. Hopefully other countries will follow, by recruiting a young generation of SIL members. Encourage your students to join SIL - their annual dues are only $5/year. And there is a 50% discount on annual dues of early career members.

Ancient Lake Ohrid Threatened

Ancient Lake Ohrid of Macedonia, 288 m depth, on the border between Macedonia and Albania in the Dinaric Alps, is one of the most evolutionarily spectacular and scientifically significant freshwater ecosystems in the world. This lake is facing a ruinous lurch to ecosystem destabilization. Government-endorsed urban plans will concrete over the last of its marshes for roads and tourist hotels, replace local fauna with non-native species, import beaches to lakeshores, and rip out key reed beds, the breeding site of the noteworthy Ohrid carp and nesting place for the mute swan, which may then abandon its role as environmental steward of the habitat. This will take place in the shadows of Galicica National Park, a UNESCO-designated biosphere, where a ski-resort and further roads are set to carve apart yet another ecosystem. All is not lost, however: Ohrid SOS, a local citizens’ initiative, is reaching out to limnologists everywhere to speak with the gravity of their expert voices and put their names to a Declaration demanding the Macedonian government halts these dual ecological catastrophes. It also calls on their wider support, should they be interested and willing. One of the most compelling evolutionary narratives ever witnessed may depend on you. We respectfully urge your signature on the Declaration.

Ancient Lake Ohrid, a limnological masterwork, boasts perhaps the highest rate of diversity of any lake by surface area worldwide. (Ljupco Lepi)

World-Renowned Australian Centre for Water Research Closed

The University of Western Australia announced its abrupt decision to close the world-renowned Centre for Water Research, headed by the Stockholm Water Prize Laureate, Prof. Jörg Imberger. CWR is, and has always been, on the forefront of international research in sustainability of freshwater resources. The announcement of closing the CWR produced a big shock wave. The loss will be felt throughout the world and the reputation of the University of Western Australia will suffer. To read more about this issue go to:

New website launched: Nomenclatura Oligochaetologica – Editio Secunda

On Monday 6 January 2014, Mark J. Wetzel (Illinois Natural History Survey, Champaign, IL) and John W. Reynolds (Oligochaetology Lab, Kitchener, Ontario, Canada) launched a new website presenting the second edition of Nomenclatura Oligochaetologica:


This web-based Second Edition of Nomenclatura Oligochaetologica [N.O.2]:

  • integrates the accounts included in the first volume (Reynolds and Cook, 1976 [N.O.]) with those presented in the three supplements (Reynolds and Cook, 1981 [N.O.S.P.], 1989 [N.O.S.S.], and 1993 [N.O.S.T.]) – together comprising the original N.O. series;
  • updates and corrects accounts for the generic, subgeneric, specific, and infra-specific names of oligochaetes (Annelida, oligochaetous Clitellata) as presented in the original series;
  • adds accounts for all oligochaete taxa described as new to science since 1993 – including barcode, GenBank, tissue repository, and other pertinent DNA sequencing information;
  • expands the Prolegomenon, Gratiarum Actiones, Praefatio, Index Auctorum, Index Auctoritatum, Index Museorum, Glossarium, and References sections of the original series;
  • includes translations (into 11 languages) of the Prolegomena and Glossaria of the original series and this second edition;
  • presents and expands the Dedicatio sections in the original series, now including biographies and memoria for ‘ancestral’ and contemporary oligochaetologists, and bibliographies of their published scientific contributions;
  • provides a forum for Current Perspectives in oligochaete phylogeny, taxonomy, systematics, and nomenclature;
  • includes a Using This Nomenclator section, with account examples and instructions for using and navigating this web-based catalogue; and
  • includes an annotated list of links to other web-based annelid resources.

The primary advantages of this web-based edition are four-fold: this format allows us to quickly address corrigenda in existing taxon accounts, add account information for newly described taxa as well as for those taxa inadvertently omitted from the original N.O. series, maintain the up-todate status of this nomenclator, and share this resource with all oligochaetologists via this openaccess medium – without cost or other administrative constraints. We encourage the assistance of our colleagues around the World – requesting that they provide us with pertinent information so that we can correct errors and efficiently maintain the accuracy and usefulness of this resource.

Interoceanic Canal in Nicaragua

Dear limnologists,

You may have heard on the news that last week the government of Nicaragua has started constructing a new interoceanic canal that will connect the Pacific and Atlantic Oceans, to create an alternative to the Panama Canal. Our colleagues from Nicaragua are greatly concerned about the ecological consequences of this canal, and in particular—the likely adverse impacts it will have on Lake Nicaragua—a large, shallow tropical lake that provides drinking water and subsistence to the population around it. More than 100 km of the canal will go right through this lake, meaning that a deep channel will be dug through it and dense traffic of trans-Atlantic ships will travel across it daily.

The scientists of Nicaragua protest that ecological-impact studies must be conducted prior to the initiation of this huge project and have asked for support of the SIL community. Below please find a link to a document they drafted, to be signed by as many limnologists as possible and then sent to the Nicaragua government as a letter from SIL.

Limnologists Warn of Impacts of an Interoceanic Canal Across Lake Nicaragua (PDF)

So far, 56 people have already signed, including several distinguished names from around the world. If you would like to add your signature to the document—please send your full name, affiliation, and country to Michael Brett (mtbrett@u.washington.edu) and Alan Covich (alanc@uga.edu).

Volume 4 of Inland Waters (2014, 444 pages) has been published

Table of Contents

It includes 3 plenary lectures from the Congress in Budapest covering topics on morphological analysis of phytoplankton by Luigi Naselli-Flores, impact of climate warming by Martin Dokulil, and the estranged twins – limnology and oceanography by John Downing. The 34 published articles cover a broad range of topics, including nutrient loading, carbon and methane flux, invasive species, radiocesium contamination, paleolimnology, stream invertebrates, hydroacoustic estimates of fish stocks, and numerous others. Nine Articles in 4(3) are publications resulting from the Plankton Ecology Group Workshop in Mexico City (12−18 February 2012); the special editors for that collection were SSS Sarma, Ramesh Gulati and S Nandini. Four Research Briefs were published in 4(4) addressing geoengineering in lakes, biochemical composition of Microcystis, impacts of food quality and quantity on Daphnia life history, and carbon dioxide emissions from dry watercourses. These short submissions are intended to promote communication of emerging issues.

All SIL members now have individual accounts that provide full access to all articles published in Inland Waters. Usernames and passwords were emailed to SIL members on 25 September 2014 from Rosalind Maberly and Karen Rouen of FBA. Tamar Zohary followed with an email to members describing this new system and the benefits of SIL membership, which includes full access to the journal.

The goal of Inland Waters is to foster scientific communication of original work, primarily by SIL members, and especially to provide opportunities for SIL early career scientists to publish. Manuscripts can be submitted any time using the online journal system maintained by the Freshwater Biological Association. Inland Waters is an ‘online first’ journal, publishing papers online consecutively and subsequently in 4 printed issues per year. Inland Waters is listed in Science Citation Index Expanded and Current Contents; all papers from Issue 1 are indexed. The journal contents and citations are tracked by Google Scholar, Scopus, Aquatic Sciences and Fisheries Abstracts, among others. The current Impact Factor is 1.43, positioning the journal in the top half of aquatic publications. We expect this metric will increase given the interesting material published in Inland Waters.

The INTERACT project under EU-FP7 has a Transnational Access program that offers access to research stations in the northernmost Europe and Russian Federation. The current TA call is open to Boreal Stations within the INTERACT network, including six stations in Norway, Finland, Russian Federation and Faroe Islands. The sites represent a variety of ecosystems from boreal forests, bogs and other peatlands, wetlands, flood plains and freshwater ecosystems to highlands and fjells, periglacial landscapes and low alpine tundra, providing opportunities for researchers from natural sciences to human dimension.

Some key areas of research that fit to the specific stations are mentioned below, but various other kinds of research can also be conducted at all stations:

You can find more information about the stations available in the call by clicking the links above to station descriptions on the INTERACT website. Applications to other INTERACT Stations offering access are not considered eligible in this call, and will be rejected from evaluation.

Transnational Access includes:

  • Free access for user groups/users to research facilities and field sites, including support for travel and logistic costs
  • Free access to information and data in the public domain held at the infrastructures

The call for proposals to the above mentioned stations for summer 2013 and winter 2013/2014 field seasons is open on the INTERACT website at http://www.eu-interact.org/ on 1-28 February, 2013.

Transnational Access is available to user groups, where the group leader and majority of group members work in an institution established in a EU Member State or Associated State. The maximum amount of access per user group is 90 person-days, including previously granted INTERACT TA. You can find the eligibility rules and application instructions, descriptions of stations and their facilities, and registration to the on-line application system from the INTERACT website.

Proposed SIL Changes

Among the items of business that the International Committee and the General Assembly will consider at the Montreal meeting, the following are most important in they have the most lasting consequences and require some thought and discussion. (Items 1-8 from the agenda.)

  1. The name of the society, presently designated “Societas Internationalis Limnologiae” or “International Association of Theoretical and Applied Limnology,” will be changed to “International Society of Limnology.” For historical continuity, the acronym “SIL” will be retained. (statutory change)
  2. SIL will no longer require members to pay dues through a National Representative. All members can pay dues directly to the SIL Administrative Assistant. The election of National Representatives will continue, as will the International Committee composed of National Representatives. (statutory change)
  3. SIL will permit the use of electronic ballots for elections. Ballots will be sent to a teller who is not a member of SIL. (statutory change)
  4. The SIL Executive Committee will create an official journal for SIL, to be received by all members of SIL in good standing with respect to dues in any given year. Papers from congresses can be submitted to the SIL journal, but will be published or rejected according to editorial judgment. Papers prepared independently of congresses also will be accepted for consideration.
  5. SIL will cease publication of the Proceedings as of the next Congress. SIL will distribute copies of abstracts for papers that are accepted for presentation at future SIL Congresses. Proceedings of SIL 2007 will be published, but with transition to a journal format. (statutory change)
  6. SIL will increase dues by 10% for the upcoming triennium.
  7. SIL documents will be prepared in English. (statutory change)
  8. SIL will encourage the organization of one non-congress meeting between congresses
