Dr. Erin McCallum, a researcher at (Forskare) at SLU in Umeå will be giving a talk about waterwater effluents and salmonid migration in freshwaters on Tuesday 5th April at 13.15 CET over zoom. Erin is a behavioral ecologist and ecotoxicologist interested in understanding the causes and consequences of anthropogenic stressors for aquatic wildlife. Erin’s seminar is entitled “A tale of two research programs: Wastewater effluents and salmonid migration in freshwaters”. She will present her current research on wastewater effects on fish communities and the migratory success of anadromous brown trout smolt. You can visit Erin’s page to read more about her research interest.

You are welcome to join this seminar free of charge via https://kau-se.zoom.us/my/kaubiology.

Dr. Hein van Kleef from the Bargerveen Foundation in The Netherlands will give a seminar entitled Sailing mostly uncharted waters when applying concepts of ecosystem resilience to enhance invasive resistance. This seminar will be streamed live over zoom on Tuesday 29th March at 13.15 CET through https://kau-se.zoom.us/my/kaubiology

Congratulations to Kalle Filipsson for a successful Ph.D. defense held last Friday (18th March 2022) at Karlstad University. Thanks to External Reviewer Professor Neil Metcalfe (Glasgow University) and Examination Committee members Professor Gunilla Rosenqvist (Uppsala University), Professor Per Larsson (Linneuniversitet) and Professor Anders Finstad, (NTNU).

On March 8th at 13.15 (CET), KAU Biology doctoral candidate Jeff Marker will present his seminar on riparian functional diversity. Measuring biodiversity in an ecosystem is more than just counting species, it is essential that we understand exactly what effects those species have on their habitats and how they shape ecosystem processes. By looking at a combination of indices and pinpointing functional traits, Jeff will walk us through the effects of forested riparian buffer and forestry management on the functional diversity of riparian spiders and plants.

Professor Hans de Kroon

On 15 March, Professor Hans de Kroon will be giving a talk on his work on Living Labs: innovative projects that have been set up for nature restoration research. With his colleagues from Radboud University (NL) and many societal partners, he looks into ways in which nature and agriculture can be integrated to ensure livelihood for farmers while conserving and restoring landscape elements that contribute to the local and regional biodiversity.

Read a bit more information on the project here, and attend the seminar via Zoom: https://kau-se.zoom.us/my/kaubiology, at 13:15 CET on 15 March.

Kalle Filipsson, RivEm Ph.D. student, nailed his Ph.D. thesis entitled “Early life stages of brown trout: Anti-predator responses under warming winters” today (25th February 2022), both at the main entrance and the biology department at Karlstad University.

On Tuesday 1 March Kalle will give a pre-dissertation talk, where he will present a preliminary version of his Ph.D. presentation. The seminar starts at 13:15 and will be held both on the second floor at the biology department and on Zoom (https://kause.zoom.us/my/kaubiology)

Kalle’s Ph.D. defense will be held on Friday 18 March. The defense will take place at 10:00 in room 1B309 (Sjöströmsalen) at Karlstad University. The defense is public and anyone is welcome to attend.

Neil Metcalfe (University of Glasgow, Scotland) will be the opponent and will participate on Zoom. Gunilla Rosenqvist (Uppsala University, Sweden), Per Larsson (Linnaeus University, Sweden) and Anders Finstad (Norwegian University of Science and Technology, Norway) are the grading committee.

Sebastian Rock electrofishing

Sebastian Rock, a LIFEConnects funded Ph.D. candidate at RivEM, will be giving a seminar on the impacts of parasitic Unionid mussels on their host fishes! These incredibly endangered freshwater bivalves are considered keystone species in their native ecosystems and are heavily protected, but will the returning salmon be able to survive in an ecosystem full of parasites? Will local anglers be upset with the habitat restoration efforts because their favorite fish are now less healthy than they were before? To find out the answers to all these questions and more! Join the seminar live on zoom https://kau-se.zoom.us/my/kaubiology at 1315 CET on 22nd February 2022.

Jacqueline Hoppenreijs, Lutz Eckstein and Lovisa Lind have a new paper out! It describes the different pressures of human activities on boreal riparian vegetation. They collected information from 182 scientific papers, books and reports and found that there are factors that are already damaging many rivers, such as hydropower (Figure 1), and factors that will become more important in the future, such as the climate crisis. More importantly, they found that these and other processes interact in ways that we don’t understand yet, simply because they’ve hardly been studied.

They combined all the effects of the pressures in one conceptual model (Figure 2), to help researchers, managers and everyone else who might be interested to ask more relevant research questions and balance different management measures with each other, so that riparian zones and the land and water around them can be protected better. The full paper is accessible through https://www.frontiersin.org/articles/10.3389/fevo.2021.806130/full#h6.

Velizara Stoilova (RivEM and Norconsult’s industry Ph.D. student) from the biology department of Karlstad University will be giving a seminar about her ongoing doctoral research entitled Existing approaches to facilitate downstream migrating fish. Velizara mainly works on solutions for fish migration and connectivity of rivers impacted by dams. As the title suggests, Velizara will be giving a talk on existing approaches to facilitate downstream migrating fish in rivers with limited connectivity and outlining her planned research.

This seminar will be streamed live on zoom on the 18th of January at 13.15 (CET). To join the seminar live on zoom, use the link https://kau-se.zoom.us/my/kaubiology. You are all welcome.

Dr. Mahboobeh Hajiesmaeli, a PostDoc Researcher from Karlstad University’s biology department and a member of the River Ecology and Management (RivEM) group will be giving a talk on how individual-based models (IBMs) of salmonid populations can be used as an effective tool for understanding and managing fish population responses to hydropeaking (hydropower short-term regulation) practices. The main focus is on the first application of an individual-based model, inSTREAM 7.2-SD, to assess the effects of peaking flows on growth, survival and distribution of Atlantic salmon (Salmo Salar) and brown trout (Salmo trutta) in the lower Gullspång River, Sweden. Lilla Åråsforsen (see picture below) was used as the study site for the IBM modeling.
