Johan_spikUnder den gångna veckan har Johan Watz spikat sin avhandling “Salmonid behaviour under winter conditions”. Kappan kan läsas online här. Avhandlingens publicerade artiklar är följande:

Paper II: Effects of ice cover on the diel behaviour and ventilation rate of juvenile brown trout

Paper III: Day and night drift-feeding by juvenile salmonids at low water temperatures

Paper IV: Prey capture rates of two species of salmonids (Salmo trutta and Thymallus thymallus) in an artificial stream: effects of temperature on their functional response

Paper V: Ice cover alters the behavior and stress level of brown trout Salmo trutta

Avhandlingens försvar kommer att gå av stapeln den 22 Januari 2016 kl. 10:15 i Nyquistsalen (9C 203) på Karlstads Universitet. Opponent är Richard Cunjak från University of New Brunswick, Kanada. Alla intresserade är välkomna.

Last Friday, Joacim Näslund, Gothenburg University defended his thesis: “The Pace of Life of Juvenile Brown Trout – Inter- and Intra-individual Variation in Growth and Behaviour“. Opponent was Robert McLaughlin from University of Guelph, Canada. John Piccolo, from Karlstads Universiy was part of the “betygsnämnd” (evaluation committee) together with Petronella Kettunen, GU och Fredrik Nordwall, HaV


In relation to the defense, a workshop on “Ecology of Stream Salmonids” was organized. At the workshop, John Piccolo presented an overview of foraging and habitat selection models for salmonid restoration.
