In order to understand the factors giving rise to a stable and annual outbreak of the pest blackfly species Simulium truncatum (Lundstrom, 1911) (Simuliidae), the oviposition habitat has been localized and the egg density quantified at different cont

Publikováno v: Waterlines. 29:147-162

Substantial sums of money have been poured into developing countries by donors, aid agencies and NGOs to improve people's access to water. However, many of the constructed water sources have broken down or are dysfunctional. At the same time, donors,

Heterogeneous deformation and mylonitization of a granulite complex, jotun-valdres nappe complex, Central South Norway

Autor: Andreas G. Koestler

Publikováno v: Geological Journal. 23:1-13

The Helgedal Zone is the Caledonian, heterogeneously deformed base of the Jotun Complex, within the Jotun-Valdres Nappe Complex (Sognefjell, South Norway). It consists of an anastomosing system of shear zones isolating lozengeshaped lenses of less de

Creation of artificial upwelling areas for brown trout, Salmo trutta, spawning in still water bodies

Autor: A. G. Koestler, Å. Brabrand, B. R. Hansen

Publikováno v: Fisheries Management and Ecology. 13:293-298

Brown trout, Salmo trutta L., spawning sites were constructed by creating areas of artificial upwelling water, 252 ± 37 mL m−2 min−1 (95% CL), through appropriately sized spawning gravel substrate in 3 m2 vessels buried in the bottom of a 150-m2

Lake spawning of brown trout related to groundwater influx

Autor: Reidar Borgstrøm, Åge Brabrand, A. G. Koestler

Publikováno v: Journal of Fish Biology. 60:751-763

Seepage water through a lake bottom and the layering of tight and high-permeable layers in the aquifer produce groundwater under greater pressure than the water column of the lake. This results in under-water springs and seepages. When spawning subst
