On April 24-25, 2023, fourteen researchers, PhD and Master students gathered at Lake Bolmen to start up the international research collaboration within the EU network AQUACOSM-plus and the national infrastructure SITES AquaNet. The study will use mesocosms to investigate how lake ecosystems are affected by browning and eutrophication. The research project is taking place simultaneously at three locations in Sweden, and Bolmen Research Station was the first to go.
The group included Silke Langenheder – SITES Erken Laboratory and AquaNet coordinator, Ingrid Sassenhage – SITES Erken Laboratory, Antonia Liess – Halmstad University, Johanna Sjöstedt – Lund University, Nusret Karakaya - Bolu Abant Izzet Baysal University, Anna Lupon– CEAB-CSIC, Susana Bernal – CEAB-CSIC, Inge Elfferich – Cardiff University, Antonija Kulaš – University of Zagreb, Kadir Yıldız – Bolu Abant Izzet Baysal University, Kevin Jones – Lund University, Eline van Dam – Lund University, Franka Hemme – Lund University and Juha Rankinen – Bolmen Research Station. At a later date Eugènia Martí – CEAB-CSIC and Nuria Carabal de Antonio - Universidad de Valencia will join the Bolmen team.

- ”This is a very exciting and important research project where we collect data from several locations in Sweden to try to figure out how the transport of nutrients and organic matter connected to different run-off scenarios may affect lake ecosystems and their water quality. Bolmen Research Station is first out and later in the the week we start the experiment in Skogaryd outside Gothenburg and the following week in lake Erken outside Uppsala”, explains Silke Langenheder, Professor in Limnology at Uppsala University and coordinator for SITES AquaNet in Sweden.
The researchers will use the mesocosm infrastrucutre to study how greenhouse gases, bacteria, algae and zooplankton in the lake are affected by increased brownification and eutrophication. The mesocosms (large floating containers) are placed in a floating platform on the lake and filled with lake water, which means that they have the naturally occurring ecosystem and the water chemistry that exists today.

- ”Climate change, variations in precipitation and how we use the land around the lake affect both the quantity and quality of the lake water, and by studying various factors that affect our lakes, we can prepare for the challenges of the future”, says Juha Rankinen, Station Manager at Bolmen Research Station.
Lake Bolmen is the most important source for drinking water production in south-western Sweden and both the quantity and the quality of water are topics that are becoming more and more relevant, both nationally and internationally. In the last two IPCC reports, water is highlighted as the central part of the climate change and mitigation measures.
- ”The experiment will last for six weeks and we will have five PhD/Master students placed at Bolmen to be able to take samples and analyze them daily. All the data we collect is then reported to SITES AquaNet and thus gives researchers throughout the world the opportunity to work with it. This collaboration between the research stations provides incredible advantages and opportunities for researchers and universities to take big steps forward”, continues Juha.

Linda Groot Nibbelink has recently started as Field technician at SITES Lönnstorp research station! Welcome to the SITES Community, Linda!

To get to know Linda, we asked for her to introduce herself to the SITES Community:
Hi! My name is Linda Groot Nibbelink. I grew up in Goes, a rural town in the Rhine delta in the Netherlands. I studied International Land and Water Management at Wageningen University & Research and Organic Agriculture & Agroecology at BOKU in Vienna, Austria and at University of Hohenheim, Germany.
Besides theoretical knowledge of agriculture, I gained practical experience by working and volunteering at organic, biodynamic and conventional fruit orchards, horticultural farms and dairy farms in Europe. Last year I did a full season internship at a plant breeding institute in Switzerland, where I worked with developing new pea varieties. After several years of moving around the continent, I decided to settle down with my partner in Lund.
At SITES Lönnstorp Research Station, my role will be to perform measurements and assessments in the experiments at the station. I will also be involved with data handling, management of experiments and taking care of samples that are collected.
What I love about working at Lönnstorp is that it allows me to combine working with my hands and with my mind. At the same time, it gives me the opportunity to learn the specifics of agriculture in Sweden and gain practical experience with field experiments.
The SITES 2023 Calendar theme is “Data in Focus”. The openly available data produced within SITES and stored on the SITES Data Portal is the “golden thread” of the infrastructure, allowing users access to ecosystem data that covers diverse habitats and climate zones across geographical gradients in Sweden. Each month follow along as we highlight a unique SITES dataset.
Wildlife monitoring is an important part of the activities at Grimsö Wildlife Research Station. A large part of the monitoring was initiated during the 1970’s, but new data series have been added over time as methods have developed. The continuous surveys focus on topics such as population dynamics, reproduction, life history traits and body measurements and include monitoring of, e.g., moose, roe deer, red fox, voles and starlings. For example, red fox (Vulpes vulpes) reproduction has been monitored since 1973 by identifying fox litters. Around 200 fox dens are checked annually within the Grimsö Wildlife Research Area and the dens with observed reproduction are summed to mirror the total number of fox litters for that year. The variation in the local fox abundance is related to the vole population cycle and is a key factor for the dynamics of several small mammal populations across Scandinavia.

The graph shows the number of fox litters at Grimsö between 1973-2021, with variations over time mainly related to vole cycles. The extra low numbers in 1985-1986 were due to an outbreak of scabies (sarcoptic mange) that regulated fox populations more or less throughout Sweden during the late 1980's and into the 1990's.
