Update on SIL Publisher


The announcement about Taylor & Francis (T&F) becoming SIL’s new publisher stimulated many queries. Below is a summary of the main points:

1. SIL members will be exempt from page charges when publishing in Inland Waters. The first author has to be a SIL member, other authors “don’t count” towards the discount. If the first author is not a member, he/she will be invited to join SIL and enjoy the exemption. Non-members will be charged by SIL a flat rate of USD 75/page. This new arrangement begins with issue 7(1) of Inland Waters.

2. SIL members (first author only) will be eligible for a substantial discount, of nearly USD 1000, on publishing their Inland Waters articles as Open Access. The discount is on the regular charge by T&F of ~ USD 3,000 per article.

3. The entire set of SIL Proceedings from all past congresses (1922 – 2010) will be digitized in the near future and made available on-line to all SIL members.


Annual membership fees for students


March 2017 is the last chance for students from developed countries to enjoy the USD5/year membership dues rate.

From 1 April 2017, student members from developed countries will be charged USD10/year. The annual dues for students from developing countries will remain USD5/year.

All will have to pay for three years at once still.

Do encourage students at your vicinity to become SIL member NOW!


SIL has new publisher


SIL has a new publisher! Starting January 2017, Taylor & Francis will be publishing Inland Waters and SILNews.

There are several major advantages to this change:

(1) SIL members will be exempt from page charges when publishing in Inland Waters (whereas non-members will be charged).

(2) Manuscripts to Inland Waters will now be handled through Editorial Manager, a user-friendly on-line manuscript processing software, replacing the system used until now.

(3) Being published by a major commercial publisher means that Inland Waters will now have a much wider distribution with over 2000 additional libraries. This larger audience will contribute to improving the journal’s visibility and impact.

(4) Here comes a most important benefit: All volumes of the former SIL Proceedings, the Verhandlungen and the Mitteilungen will be digitized in a searchable format. Within a few months these huge but currently mostly inaccessible volumes will become available on-line for free viewing and downloading to all SIL members. This immense database of knowledge, starting with Volume 1 of the Proceedings published in 1922, will soon be available to all of us, with easy sorting by author or title. Non-members will be charged for this access.

To accommodate these changes SIL had to revise the criteria for who is a SIL member. While in the past you would continue to be a member if you didn’t pay dues for up to 3 years, this will not be possible in the future. From now on, only those who pay their annual dues will be considered members that are eligible for the above benefits. It is therefore time to pay your dues for 2017, either through your National Representative, to the SIL Office, or directly on the SIL website.

Note also that the next 2 months is the last chance for students from developed countries to enjoy the 5 USD/year membership dues rate. From 1 April, student members from developed countries will be charged 10 USD/year. The annual dues for students from developing countries will remain 5 USD/year. All will have to pay for 3 years at once still. So, do encourage students at your vicinity to become SIL member NOW!


SIL election results

07/11/2016 / Tamar Zohary

It is with great pleasure that we announce the newly elected students/early career members of the SIL Executive Committee.

They are:

  1. 1. Camilla Capelli from Italy
  2. 2. Iestyn Woolway from the UK
They will start their terms at the SIL Congress in Torino.
Let us all wish them good luck and lots of success!

Proposed changes to the SIL Statutes

07/11/2016 / Tamar Zohary

The SIL Executive Committee proposed several changes to the SIL Statutes, as detailed below. It is SIL’s custom to advertise such changes before a congress, then vote to approve the changes at the General Assembly meeting in the congress. The changes proposed by the Executive Committee reflect changes that have already taken place de-facto, but as of today – are not written into the statutes. To summarise these changes:

Clause 4 SIL membership and Dues:

  • 1. A new membership category was added: Early Career Member (50% dues of Ordinary member).
  • 2. The description of the category of Emeritus Members was re-worded to reflect the current state, with on-line access to Inland Waters replacing the past shipping of hard copies of the Proceedings. The same change was made at other places in the document
  • 3. The Student Member category was re-worded to reflect changes that already took place
  • 4. A clause was added about members from developing countries having a 50% reduction on dues.


Clause 11 Executive Committee

  • 5. Addition of 2 student/early career representatives to the Executive Committee (EC).
  • 6. The expansion of the EC from 5 to 7 members led to changing the number of people constituting a quorum, from 5 to 6.
  • 7. Since congresses are now conducted at 2-yr intervals, “triennium” was changed to “biennium or triennium”


Item ViI.  Congresses



Clause numbers were adjusted.


Please see the Statutes page for a draft copy of what will discussed at the SIL Congress in Torino.


Impact factor for Inland Waters increases


Jack Jones, editor-in-chief of Inland Waters reports that its impact factor in 2015 is now 1.776, increased from 1.31 last year. This now places the journal eighth out of 20 titles in the Limnology category – not bad for a fledgling journal. This is an excellent improvement to the status of SIL’s peer-reviewed journal.


Elections for 2 student/early career SIL board members


SIL is holding now elections for two new student/early career members to join its executive committee. This is a new move for SIL, never before did the Executive Committee have a chair reserved for young members. Now SIL has added two chairs that are reserved for young members. To exercise your right to vote, look for an email sent to you on 16 June from Denise Johnson, with details on the six candidates and instructions on how to vote. If you do not receive the email, please write Denise at and she will send you the information. The deadline for voting is 30 June 2016.


Students publish paper as result of SIL course in Brazil


Frontiers in Microbiology has published a paper that is the
outcome of a fruitful practical SIL course that happened in Brazil in
2014. All participants of the course (graduate students, post-docs and
university professors) authored the paper, entitled “High primary
production contrasts with intense carbon emission in a eutrophic
tropical reservoir.” This paper adds to the current understanding of
the interactions between eutrophication and carbon cycling, and it is
one of the first reports on the carbon cycling of Brazilian semiarid
artificial lakes. These systems are present throughout northeastern
Brazil but have been poorly studied so far.

The article is freely available on Frontier’s website:


Student sought for SIL Executive Board


The SIL Nominating Committee is seeking (self-)nominations for a student/early career member of the SIL Executive board, to serve for a period of 2 years (with an option to be re-elected for a second term), and to be elected before the next congress in Turin (2016). Candidates must be SIL members (or have applied to join SIL), holding a PhD studentship, or a post-doctoral or similar position, and have been born in 1981 or later.

Candidates should submit a photograph and a paragraph about him/herself, stating what s/he would like to do for the younger generation of limnologists if elected to the SIL board (one page max, plus the photograph). On this basis, the SIL Nominating Committee will select candidates to be put up for an election by the SIL membership. Members of the SIL Nominating Committee are: Luigi Naselli-Flores (Chair), Carolyn Burns, Paul del Giorgio, Alan Hildrew and Tamar Zohary. Applications should be submitted to the Chair ( no later than 15 May 2016. Elections will be held electronically (by e-mail) at the beginning of June.

SIL 2016 Congress

/ 31 July - 5 August 2016 / Torino, Italy

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, approach via the Ohrid SOS Facebook page, or refer to our website at


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.


External Quality Assessment Trials Phytoplankton


The State Reservoir Administration of Saxony as a state-owned enterprise in the line of business of the Saxon Ministry for Environment and Agriculture and the Working Committee Drinking Water Reservoirs r.a. (ATT) will conduct a proficiency test of phytoplankton in 2015-2016. This is the seventh international proficiency test since 2007.

Interested parties may register online on the web portal from 15 June to 30 September 2015.


Advanced Course on Cyanobacteria and Cyanotoxins


Where: Universidad  Autónoma de Madrid, Spain
When: 29 June – 4 July 2015

This course is funded by NILS and CYANOCOST and will provide fellowships for most of the trainees. It will be a good opportunity to disseminate information about this issue and to help educate a new generation of cyanobacteriologists.

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

01/19/2015 / 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 >>>

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 ( and Alan Covich(
