We modified, parameterized, and applied the individual-based model inSTREAM version 6.1 for lake-migrating populations of landlocked Atlantic salmon (Salmo salar) and brown trout (S. trutta) in a residual flow stretch of the hydropower-regulated Gullspång River, Sweden. This model description is structured according to the TRACE model description f...
Known as the "king of fishes," the Atlantic salmon (Salmo salar, Salmonidae) is an iconic freshwater species whose contribution to human well-being has long been recognized , as have widespread declines in its abundance, partly due to river regulation. To understand how salmon conservation has been addressed within the ecosystem services (ES) frame...
Describing and understanding the relationship between streamflow and ecological processes is a classic problem in stream ecology and river management. We applied the individual-based model inSTREAM to describe the relationship between the dynamic river habitat and emergent population responses in sympatric landlocked Atlantic salmon (Salmo salar) a...
Cost-effective implementation of fish-friendly hydropower flow operation and habitat restoration measures require an understanding of their effects on fitness-related behaviours of stream fish. Here, we investigated how changes in flow and bottom structure influence the social behaviour of European grayling, using large experimental flumes (700 L s...
Half the world’s river volume is affected by flow alterations and/or fragmentation –a figure that is likely to increase with the current global surge in hydropower development. Streamflow shapes the river habitat for species like Atlantic salmon (Salmo salar) and brown trout (S. trutta) –species that need rivers for reproduction and for juvenile re...
Introduction paper (7.5 credit course) - a part of my licentiate degree at Karlstad University.
This presentation is an introduction to environmental evidence synthesis and -systematic reviews, and was given as a part of the Tuesday seminar series at the Department of Biology, Karlstad University.

I think species identification using keys in books and compendiums is rather ineffective because you always have to look up the next step and associated pictures on different pages. So I was wondering if there are any simple and free tools to digitize the key? At each step you choose the best fit between two descriptions, and I would like to have both text and pictures (interactive if possible) in the description. I've seen some local botanical keys that filter results based on answers to short questions, but that's not really what I'm looking for. It should ideally be possible to start the key on any taxonomic level. Any ideas?
I have created a quadrangular mesh of ~1m^2 area elements that I'm trying to interpolate in MIKE Zero (2019 version) Mesh Generator for use in MIKE 21 FM. I have only one scatter data file, a dfs2 file. When I try to interpolate I get an error "unable to triangulate scatter data" or no error message other than "interpolation failed". I have tried with default interpolation parameters, and both linear and natural neighbor. Does anyone have an idea?
... on the format Days = a*(temperature - c)b, where a, b and c are constants (this formula is called "the power law with temperature correction"in Crisp (1981) and the log-inverse Belehrádek model in Beacham & Murray (1990)). If anyone knows of a study that has applied this formula to the time to 50% emergence please let me know. Crisp (1981) gave estimates of constants for the formula for Atlantic salmon and brown trout, but that only until 50% hatching.
OR if anyone has actual raw data on days until emergence vs temperature so I can fit the formula myself I would be immensely grateful!
Need to find a, b and c for parameterizing a model :) Thanks!
