Knowledge Bank: Lakes and Watercourses

Community elders showed the effects of forestry

Solomon Gebreyohannis and Professor Kevin Bishop have been studying the relation of forest cover and river flow in the Koga watershed, a headwater of the Blue Nile in Ethiopia. (2011-12-14)

Robust computer model for load calculations

The "Fyris" model is a calculation model capable of mapping transport and source distribution of nitrogen and phosphorus from a catchment to the sea. (2011-08-19)

Genetic identification to protect fish

SLU researchers have been counting young salmon and brown trout on their way to the sea in a forest river called Sävarån. (2011-08-18)

What natural environment do we want?

SLU researchers have played an important role in Sweden’s 150 year long history of environmental acidification, for instance the acidification process was first shown by soil researcher Svante Odén in the 1960s. Reduced sulphur emissions and thereby less acid deposition, makes land and water areas in Sweden now recovering from the acidification that started already during the 19th century. But towards...

Diatoms indicate water quality

SLU in Uppsala now has an accredited laboratory capable of analysing diatoms from watercourses. (2011-07-06)

Later coastal fishing favours wild salmon

Robust salmon stocks in the Baltic Sea are possible with the right knowledge and fishing methods, as suggested by Professor Hans Lundqvist and Associate Professor Kjell Leonardsson at the Department of Wildlife, Fish and Environment at the Swedish University of Agricultural Sciences (SLU).

Surveying the occurrence of hermaphrodite roach (Rutilis rutilis)

British studies have revealed that a large proportion of roach found in waters close to municipal sewage works are hermaphrodite. (2011-05-11)

Green restoration of cutover peat areas after finished peat cutting

A frequent after-use alternative after finished peat cutting is afforestation. But in the field of nature conservation, there is a big interest in restoring the hydrology in cutover peat areas, converting them into new wetlands. (2011-05-09)

Forest Harvesting Resulted in Unexpectedly Low Mercury Export

Professor Kevin Bishop and Ph D student Karin Eklöf at the Swedish University of Agricultural Sciences (SLU) participate in a project on the effects on nearby watercourses after a complete felling in a catchment area. (2011-03-21)

Diatoms reflect lake quality

Stationary diatoms reveal whether a river or stream is eutrophied, acidified or affected by organic pollutants. Researchers at SLU in Uppsala are now determining whether the method using diatoms as an indicator in watercourses also works in lakes. (2009-11-30)
