Today Lea Schneider successfully defended her PhD-thesis ”Conservation ecology of the thick-shelled river mussel Unio crassus – the importance of parasite-host interactions” at Karlstad UniversityCaryn Vaughn (University of Oklahoma, USA) was the opponent, and Leonard Sandin (Swedish University of Agriculture), Niklas Janz (Stockholm University, Sweden), and Annie Jonsson (University of Skövde, Sweden) constituted the grading committee (betygskommitté).

Lea Schneiders supervisors during her PhD were Martin Österling and Anders Nilsson from Karlstad University, and Johan Höjesjö from the University of Gothenburg, Sweden. Her work constituted on part of the LIFE-project UCforLife – Målarmusslans återkomst.

Next week, Daniel Nyqvist, PhD-student at Karlstad University, will defend his (my…) thesis “Atlantic salmon in regulated rivers: migration, dam passage, and fish behavior”. The defense will take place on Friday, December 9th, at 10:15 in room 9C 203 on Karlstad University. The abstract and the frame of the thesis are available online here.

Scott Hinch (University of British Columbia, Canada) is the opponent and Eva Thorstad (NINA, Norway), Kim Aarestrup (DTU AQUA, Denmark) and Hans Lundqvist (Swedish University of Agriculture) constitute the grading committee (betygskommitté). The visiting researchers will give seminars at Karlstad University on Thursday, December 8th. The seminars start at 14:15 in room 5F322:

Scott Hinch: Using telemetry in adaptive management experiments at fish passage facilities

Eva Thorstad: New results on downstream migration of eel and salmon past power stations in Germany

Hans Lundqvist: Wild Baltic stocks of Atlantic salmon in northern Sweden: Where are we and where are we going in Umeälven?

Kim Aarestrup has yet to disclose the title of his seminar.

Everyone is welcome to attend both the PhD-defense and the seminars.

Today Åsa Enefalk successfully defended her PhD-thesis ”Fine stream wood – Effects on drift and brown trout (Salmo trutta) growth and behavior”. Theopponent was Stanley Gregory from Oregon State University whereas the grading committee consisted of Teppo Vehanen, Natural Resources Institute Finland, Ingrid Ahnesjö, Uppsala University, and Erik Pettersson, Swedish University of Agriculture.

Åsa Enefalk’s supervisors during her PhD were Eva Bergman, Anders NIlsson and Raimo Neergaard
