1. Flow design for migrating fish
Abstract : The utilization of rivers for hydropower production leads to problems for migrating fish, such as Atlantic salmon (Salmo salar) and sea trout (Salmo trutta). Both salmon and trout reproduce in fresh water, but spend their adult years at sea. To overcome man-made obstructions to and from the spawning grounds the fish needs help. READ MORE

2. Physical modelling of acoustic shallow-water communication channels
Abstract : Akustiska kanaler för undervattenskommunikation är flervägskanaler där ljudet reflekteras från havets yta och botten och bryts vid ljudhastighetsförändringar. I grunt vatten är impulssvaret långt jämfört med symbolernas tidslängd i ett utskickat meddelande. READ MORE

3. Geography and geometry of pre-Caledonian western Baltica: U-Pb geochronology and Palaeomagnetism
Abstract : In an attempt to reconstruct the pre-Caledonian cratonic margin of Fennoscandia, U-Pb geochronological and geochemical investigations have been performed on allochthonous orthogneisses in the northern Swedish Caledonides. The crystalline basement of the nappes have also been examined to further constrain the continuation of various chronologically defined orogenic belts. READ MORE

4. Nest-site attendance and foraging ecology of the Northern Fulmar (Fulmarus glacialis) on the Faroe Islands. Is the Northern Fulmar a useful indicator of ecosystem productivity and pollution?
Abstract : The Northern Fulmar (Fulmarus glacialis) is one of the most abundant seabirds in the Northern Hemisphere and the most abundant seabird on the Faroe Islands. Except from a few sporadic observations up until the 1950´s no study has focused on this species on the Faroe Islands. READ MORE

5. Evolutionary dynamics of migration and breeding in wild birds: genetic architecture, sexual conflicts and evolutionary constraints
Abstract : Our knowledge of the evolutionary potential of traits involved in different selective episodes, especially in natural populations, is still limited. This is true for questions such as the genetic basis and inheritance of traits, how natural and sexual selection acts on them, and how selective conflicts influence the evolutionary response to selection.
