Behaviour and Ecology of Drift ForagingPosted by Daniel Nyqvist | Död ved, Vinterekologi
“A stream is defined, after all, as flowing water. Its inhabitants are the product of millennia of adaptations to the unique selective pressures created by this dynamic environment. Imagination is key for many of us who have studied fish feeding in swift water.” skriver John Piccolo med flera i förordet till Environmental Biology of Fishes special nummer om drift-feeding: “Behaviour and Ecology of Drift Foraging: From Theory to Practice“.
En handfull NRRV-relaterade artiklar är med i specialnumret:
*Food and space revisited: The role of drift-feeding theory in predicting the distribution, growth, and abundance of stream salmonids.
*Day and night drift-feeding by juvenile salmonids at low water temperatures.
*Familiarity with a partner facilitates the movement of drift foraging juvenile grayling (Thymallus thymallus) into a new habitat area.
*Woody debris and terrestrial invertebrates – effects on prey resources for brown trout (Salmo trutta) in a boreal stream
*Parasitic freshwater pearl mussel larvae (Margaritifera margaritifera L.) reduce the drift-feeding rate of juvenile brown trout (Salmo trutta L.).
