All Sunday workshops will be off main venue - at the Faculty of Science, Deptartment of Biology building ( Rooseveltov trg 6) - 3 minutes walk (Google’s estimate is wrong, there is a shortcut)

WS1. Still waters run deep: Past, present and future scientific careers in limnology

As a young researcher one confronts the question of, what are your plans? We know it is a hard question, sometimes because there are many doors open but nothing set, and in other cases because one does not know where to start. In this workshop, based on an online survey, we will discuss how academic career paths have changed over time, and the new challenges, opportunities, potential careers for researchers.

Leaders: EFYR (Zeynep Ersoy, Fredric Windsor, Nabil Majdi, Clara Mendoza-Lera)

Time: 13 - 16h

Participants: 30

WS2. Advanced analysis of ecological and environmental data

In our workshop, we will provide an overview of novel methods of data analysis for ecological and environmental data. We will first give an overview on how to identify explanatory variables and their relevance in statistical models in cases of small data sets, which often applies to field studies on streams or lakes. Then, we will introduce methods to take the spatial relationship between sites on a stream network into account in the analysis. Finally, we will show how Generalized Additive Models (GAM) can be used to fit models in the case of complex relationships between variables. Participants will gain most from the workshop if they are familiar with the R language. The participants will be provided with example data sets, computer code and presentation slides to repeat the analyses on their own. Participants are welcome to bring their own data sets for the exercises (preferably not too large subsets).

Leader(s): Ralf Schäfer, Mira Kattwinkel, Andreas Scharmueller

Time: 10 - 17h (3 × 2 h)

Participants: 60

WS3. Collaborative decision-making: theory and application of Multi-Criteria Decision Analysis for managing fresh waters

This will be a 3.5 hour workshop dedicated to a well-known participatory decision support framework based on multi-criteria decision analysis (MCDA). MCDA can be used to support community-inclusive decision-making for any kind of application. Here, we will introduce it for freshwater management. In many countries (and also in the European Union), it is nowadays mandated, or at least recommended to include community values in freshwater management decisions. However, guidance on how this complex process should be undertaken is rarely given. Freshwater collaborative processes require the input of scientists, managers, locals and industry stakeholders. Many of the SEFS participants will have been involved in such processes and it will be interesting to critically compare the MCDA process with other approaches. Furthermore, many SEFS participants may be involved in such processes in the future and this workshop will give them a deeper understanding of how MCDA operates including its strengths and weaknesses.

Leaders: Simone Langhans, Martin Friedrichs

Time: 12.30 – 16 h

Participants: 30

Monday 1.7.

Workshops will take place at the venue

WS5. Open workshop to promote international collaboration in aquatic mesocosm sciences – including funding opportunities for transnational access to AQUACOSM-research facilities in 2020.

In this workshop we wish to:

A. Inform about upcoming funding opportunities to work at leading European mesocosm facilities in 2020, through the European H2020 AQUACOSM-project (, specific information will be available at ( The activity is open for a wide range of applicants, globally - up to 20 % of the participants can originate from any country in the world, while the majority of applicants are expected to originate from within the European and associated countries. Persons from countries without such facilities and from Eastern EU are especially encouraged to apply.

B. Further develop the international virtual network: including all types of aquatic mesocosm facilities, spanning from freshwater river and lakes to brackish estuaries, marine coastal and open ocean. We further wish to connect this to other networking initiatives on aquatic mesocosms.

C. Provide a forum for all mesocosm facility providers attending the SEFS11 meeting to present and discuss future project ideas and collaborations with potential users at this meeting.

Leaders: Stella Berger, Meryem Beklioğlu, Lisette de Senerpont Domis, Jens Nejstgaard

Time: 1.5 - 2 hours

Participants: 40

WS7. Predicting in-lake responses to change using near real time models

Innovative modelling tools of lake water quality that are linked to near real time data from sensors have the capacity into provide actionable information to support water management. The Water JPI PROGNOS project (Predicting in-lake responses to change using near real time models - has developed an integrated approach that couples such high frequency data to dynamic models to forecast short-term changes in lake state, and thus inform management decisions to safeguard the ecosystem services that lakes provide. It focused on two important issues for water management: increases in dissolved organic matter and nuisance algal blooms.  In this workshop we will 1. give an overview of the project, 2. give a demonstration of the tools that have been developed in PROGNOS and 3. present details on cost benefit analysis on using such tools and monitoring for case studies from European lakes.

Leaders: Eleanor Jennings, Gideon Gal

Time: 2 hours (after sessions i.e. probably 18-20h)

Participants: 25

The FEST: First Ever SEFS Taxonomy Fair

The First Ever SEFS Taxonomy Fair will take place at the SEFS11 under a motto: "lets come together – all specimens welcome".

This will be an opportunity to interact with leading experts in the fields of taxonomy.

The idea is for the researchers bewildered by their own specimens to be able to fearlessly bring the specimens to the experts at hand and either solve their problem or at least be consoled by an authority in the field.

The taxonomic experts will most likely gather at the FEST after sessions on Monday (the exact day and time - to be announced). Everyone is invited to bring in the tricky, or unknown specimens and experts will take a look.

Talk to people, learn and share – you are not alone .

SEFS11 team invites all willing and able taxonomists to contact us directly at for adding their expertise / taxon to the list or just helping the already listed volunteers.

Group Expert(s)
Chironomidae Dubravka Čerba, Zlatko Mihaljević, Đurađ Milošević
Other Diptera Marija Ivković
Trichoptera Ana Previšić
Ephemeroptera Marina Vilenica
Odonata Surprise(d) expert
Hydrachnidia Ivana Pozojević, Vladimir Pešić
Coleoptera (Elmidae) Vlatka Mičetić Stanković

Time: 2 hours (after sessions i.e. probably 18-20h)

Venue: Department of Biology, Rooseveltov trg 6, 1st floor – stage right

PS – there may or may not be a jam session after and/or during the FEST (currently we have an expert accordion player, so any and all musically endowed SEFSians are cordially invited to contact us at to join the jam session team)

Please follow the rules of traveling with specimens as best as you can.
