Raviv Gal, PhD Student

Raviv Gal, PhD student at NRRV, will give a seminar about freshwater mussels as ecosystem engineers. Freshwater mussels are a highly endangered group with a fascinating life history and an important role in the ecosystem. Raviv will tell us about what we know about the role of mussels in freshwaters, with a focus on his own research into their interactions with the rest of the benthic macroinvertebrate community and decomposition processes. Date and Time: Tuesday 19 September 2023 at 13:15 CET. You can join this seminar live on Zoom (https://kau-se.zoom.us/j/63110430909) or in Room 5D306 at Karlstad University campus. You are all invited.

On 15-6-2021 Sebastian Rock will be giving a talk introducing his work on the host-parasite interactions of unionid mussels. Within the broader LifeConnects projects, this work will improve mussel conservation and reintroduction efforts of this little studied order of bivalves in Sweden and around the world.

On Tuesday 16 February Kaj Hulthén will give the seminar “Causes and consequences of partial migration in a freshwater fish”. Kaj works as a researcher in the research group Aquatic Ecology at Lund University. Kaj is particularly interested in intraspecific variation in migratory behaviour and works primarily with partially migratory fish populations in the lakes of southern Sweden. During the seminar Kaj will mainly talk about why certain individuals make the decision to migrate whereas others choose to stay as year-round residents.

The seminar starts at 13.15 and will be streamed live over Zoom. Contact Olle Calles (olle.calles@kau.se) to receive the zoom link to this seminar.

On Tuesday 8 December Kalle Filipsson, RivEM PhD student, will present his work on how elevated temperatures and predator presence during egg incubation affect development and behaviour of brown trout. The seminar starts at 13:15 and will be streamed live on Zoom. Contact Kalle (karl.filipsson@kau.se) if you are interested in attending the seminar, and he will send you a link.

On Tuesday 26 May Roman Motyka, NRRV PhD student, will give a seminar entitled “The role of behavior and habitat use in conservation biology of the European eel (Anguilla anguilla). During this seminar, Roman will present his plans for his PhD project.

The seminar starts at 13:15 and will be held online and streamed via the video communication system Zoom. Everyone who wants to attend the seminar are welcome to do so. We will not distribute the zoom link to the seminar publicly online. If you want to attend the seminar, contact Roman (roman.motyka@kau.se) or Olle Calles (olle.calles@kau.se), and they will send you a zoom link so that you can participate.

On Friday 13 March, Kalle Filipsson, NRRV PhD-student, will defend his (my) licentiate thesis. The thesis has the title ”From behaviour to genes: anti-predator responses of brown trout (Salmo trutta) under winter conditions”. The defense will be held in room 1B309 (Sjöströmsalen) at Karlstad University, and starts at 10:00. Stefán Óli Steingrímsson, Professor at Hólar University, Iceland, is the opponent. The defense is open for everyone who wishes to attend.
