World Climate Statement


Statement of World Aquatic Scientific Societies on the Need to Take Urgent Action against Human-Caused Climate Change, Based on Scientific Evidence

Water is the most important natural resource on Earth as it is vital for life. Aquatic ecosystems, freshwater or marine, provide multiple benefits to human society, such as provisioning of oxygen, food, drinking water, and genetic resources; regulation of atmospheric composition and climate; water purification; storm buffering; mitigation of floods/droughts; recreation areas; and other purposes. Our existence and well-being depend on the health and well-functioning of aquatic ecosystems. People naturally distribute around water -approximately 40% of the world’s population lives within 100 km (62 mi) of a coast.
The world’s aquatic resources are now under their greatest threat in human history. Human-caused climate change is accelerating the degradation of aquatic ecosystems and the services they provide. Aquatic ecosystems are among the most affected worldwide (e.g., in case of freshwater ecosystems, one measure of biodiversity, the freshwater living planet index for species populations, declined 83% from 1970 to 2014, while up to 90% of coral reefs will disappear by mid-century if the current trends continue).
We, the world’s aquatic scientists, spend our lives studying these systems. We see exceptional and disturbing changes in the world’s aquatic ecosystems due to climate change and believe that we must continue to share peer-reviewed scientific findings with the public and policymakers to emphasize the seriousness of this threat and the need for immediate action. For the first time, the assessment of global risks conducted by the World Economic Forum ranked the impact of “climate action failure”, “biodiversity loss,” and “water crisis” among the top five risks over the next decade.

In recent years, migration has increased and geopolitical tensions have been exacerbated: between 2008 and 2016, more than 20 million people per year have been forced to move due to extreme weather events, while according to the United Nations, in 2017, water was a major conflict factor in 45 countries.
These negative effects are expected to increase under current climatic trends. For example, in the United States, the climate-related economic damage is estimated to reach 10% of the gross domestic product by the end of the century. In Europe, the minimum cost of not adapting to climate change is estimated at €100 billion per year in 2020 and €250 billion in 2050.

Experts in environmental, social, and economic fields collectively point towards a severe environmental and humanitarian crisis, with repercussions at a global level, unless worldwide concerted climate actions are implemented urgently.
This document summarizes key scientific findings highlighting the effect of climate changes on
aquatic ecosystems. These findings provide evidence of what effects are currently happening and why world policymakers and all of humankind need to act jointly and launch concerted actions now if they wish to mitigate these impacts.

The full statement can be found here.


10th International Shallow Lakes Conference

Dear SIL members,

We are pleased to announce the new date and format of the 10th International Shallow Lakes Conference. The conference will be held online from March 1st to 5th, 2021. We would like to invite you to take a look at our updated website ( Shallow lakes are important freshwater ecosystems worldwide, contributing in important ways to biodiversity and ecosystem services locally as well as at the landscape scale. Shallow lakes are embedded in heterogeneous landscapes, and their density and surface area are important determinants of landscape connectivity that influence metapopulation, metacommunity and metaecosystem dynamics. Thus, in addition to the traditional topics addressed on previous shallow lakes conferences, we take the opportunity of this 10th meeting to devote special attention to landscape ecology and its importance to understand the structure and function of shallow lakes.

Landscape ecology focuses on the relationships between spatial pattern and ecological processes, and considers spatial scales that extend well beyond the individual system traditionally studied by ecologists and limnologists. From a landscape perspective, conceptual frameworks have been proposed to emphasize the importance of ecosystem boundaries, including their permeability and resistance to flows of energy and materials and to the dispersal of organisms, and the challenges of managing systems to maintain biodiversity and ecosystem services at the landscape scale. Understanding the implications of the dynamic landscape mosaic for ecosystem processes remains a frontier in both ecosystem and landscape ecology, and is actualized also in the ongoing global change perspective. Despite the great advances in shallow lake ecology over the last decades, we do not yet sufficiently grasp all consequences of regional processes for the structure and the function of shallow lakes. We think there is a great opportunity to integrate ecological theories that address both the role of local and spatial processes for population, community, and ecosystems dynamics in shallow lakes, and to consider the implications for their management.

Thus, we invite limnologists to join the 10th International Shallow Lakes Conference to present their recent work on shallow lake ecology and discuss current challenges and opportunities toward a landscape ecology of shallow lakes. The deadline for registration is Nov 27th, 2020 and for abstract submission is Nov 30th, 2020. The deadline for the submission of the video with the oral presentation is January 30th, 2021, and for the paper submission to a special volume of the journal Hydrobiologia is March 30th, 2021, just after the congress. Due to time zone problems, the congress will happen from 8 to 12 a.m. (BRT, Brasilia Time, UTC-3). This time is morning in the Americas, Afternoon in Europe/Africa, and evening in Asia/Oceania. The registration fee is now 25% of the original price and we hope that with the reduced registration fee and the online format,  more students and professionals from developing countries will be able to attend the conference.

With my best regards,

José Luiz Attayde

New date for the 4th International Conference on the Status and Future of the World’s Large Rivers, Moscow


Just like many conferences, the 4th International Conference on the Status and Future of the World’s Large Rivers has been postponed!

New date: 2-6 August 2021
New abstract submission deadline: January 31st 2021

The pressures and impacts on the World’s Large Rivers have increased greatly in recent years. Large rivers are particularly exposed to problems of multiple uses, often with conflicting aims. At the global scale, there is no comprehensive assessment of the current status of the World’s Large Rivers, the conflicting demands on such rivers, and likely future anthropogenic impacts, as well as the potential for restoration and the associated problems.

Therefore, the World’s Large Rivers Conference aims in providing a global forum for a wide-ranging discussion of key issues related to research on large rivers and to their effective and sustainable management, involving both scientists and decision makers.

Scientists and practitioners are strongly encouraged to present their research results and experiences in the fields of:

– Hydrology, Hydraulics & Hydroclimatic Impacts

– Sediment Transport & River Morphology

– River Pollution, Ecology & Restoration

– Integrated River Management

As well as in a special session about

– Russian / Arctic Rivers

Special focus throughout all sessions will be given this time to Climate Change and River Response.

Call to our members: COVID-19 and the declining anthropogenic effects on our aquatic systems

Dear SIL members and colleagues,
The current Covid19 pandemia has brought many of us into situations that are perceived uncertain and potentially dangerous. I wish you all that you can address the challenges properly, and that you and your families stay safe.
The SIL Executive Board continues working and is developing plans and actions how we as a society can cope with the changed scientific environment. However, we also note that the pandemia induced a large-scale experiment, during which the anthropogenic effects on the aquatic system are massively changing, at least for the current weeks and months. Negative effects from industry and agriculture may become weaker, whereas the use of aquatic systems for recreation may even increase, in particular towards the summer in the northern hemisphere.
Therefore, we ask you, our members, to help documenting these changes. If it is legally safe, please continue with monitoring your field sites. If you run field sampling, try to obtain samples that are comparable to samplings in previous years. We may later think about initiatives to accumulate this information to make the use of the aquatic systems more sustainable in the long term.
In the short term, pictures and short stories are welcome that document the changes relative to previous years. Please share them on our SIL social media channels, using the hashtag #HealingInlandWaters and/or filling out this form:
Facebook: SIL – The International Society of Limnology

Stay safe
with my best wishes to all of you

Biodiversity under concerted attack in Brazil


Brazil harbours the planet’s greatest biodiversity, but President Bolsonaro’s administration is undermining advances in environmental conservation achieved during the last decades. Just to cite some examples, the federal government has withdrawn the offer to host the next Conference of the Parties on Climate Change, legalized pesticides prohibited in other countries and dismantled federal environmental protection agencies. In view of these kickbacks, 602 European scientists and two indigenous organizations recently argued that Europe should make trade with Brazil sustainable (1).

The greatest threat so far is a bill in discussion by the Senate to eliminate the Legal Reserve requirement from the 2012 Native Vegetation Protection Law (2). Currently, with some exceptions, Legal Reserves are required to maintain forest and/or non-forest native vegetation cover on at least 50 to 80% of every property in the Amazon, 20 to 35% in the Cerrado savannas, and 20% in remaining regions. If passed, this bill will likely trigger swift and irreparable biodiversity losses in Brazil and jeopardise climate change mitigation efforts.

For political leaders of the rural sector supporting this bill, encroaching on native vegetation is a convenient way to boost agricultural production, mainly of beef and soybean that are mainstays of Brazil’s floundering economy. However, improving productivity on already converted land could well meet demands for several decades without reducing native vegetation (3). Furthermore, Brazil´s economic dependence on commodities is worrisome as commodity dependent countries usually have lower human development indices (4).

Against all reason, scientific evidence is being systematically disregarded by the hegemonic group holding power in Brazil (5), with likely long-lasting catastrophic impacts on biodiversity and society. For the sake of environment security, further engagement between scientists and policy-makers is urgently needed to demonstrate the role of Legal Reserves in maintaining essential ecosystem services that benefit farmers, society and the Brazilian economy in the long term.

Lake Baikal Support


Lake Baikal, the world’s oldest, deepest and largest (by volume) freshwater lake, was recently threatened by intentions of the Russian government to relax regulations regarding inflows and loading of contaminants. The SIL executive board responded with a strong letter urging the authorities to protect this precious iconic lake.
As a truly international society, such actions are a main role of SIL.

The above letter from SIL, together with several support letters from scientists and associations worldwide, indeed helped to convince the Russian Authorities to cancel their plan of relaxing the regulations for inflows into Lake Baikal. Read below the reply to our letter.

“Dear colleagues, friends,

This letter of thanks acknowledges our deep gratitude to you for raising your voices in favour of Lake Baikal, the one for the Planet. Although it is a tiny piece of our Earth, no one would deny it being one of its pearls, and as a magnificent gift from the nature, it needs our care and protection. Global environmental problems are obviously piling up, but you do not step aside and stay involved. With your strong voices, we succeeded in suspending the draft regulations concerning emissions into Lake Baikal, which were not logical and technologically reasonable. At the moment, the government comes to the opinion that the construction of treatment facilities at Lake Baikal should be based on the best world technologies. Yours suggestions and examples have contributed to this opinion.
We greatly appreciate your concern, help and advice and hope that our mutual efforts, scientific experience and good will would contribute to the world’s and Baikal’s healthier future.

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

General 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

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. For further information about this meeting check our website: Or contact: Miss Ningning LIU Institute of Hydrobiology Jinan University Guangzhou 510632 Email:

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. More information:


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.

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.

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( Sincerely, Dr. Tamar Zohary SIL General Secretary-Treasurer
