The objective of this chapter is to give an overview and analysis of the current trends and developments in biotechnology in aquaculture research and management. The technological developments along with structural changes in the aquaculture sector may affect access and intellectual property rights (IPR) regimes. These issues will be discussed in a wide perspective involving both short and long-term ...

In 1977 a monument in memory of the Finnish immigrants was erected in Vadsø, the capital town of the county of Finnmark. The unveiling ceremony of the monument was an exceptional event, where the Norwegian king Olav, the Swedish king Carl Gustav and the Finnish president Uhro Kekkonen attended. The purpose of the monument was to pay tribute to the Finnish immigrants and their contribution to the ...

The newly discovered deep-sea hydrothermal vent field “Loki’s Castle” at 2,350 m depth at 70°N on the Knipovich Ridge north of the island Jan Mayen is the only known black smoker field from the Arctic Ridge system. This vent field holds a unique fauna clearly distinct from vent sites along the Mid-Atlantic Ridge south of Iceland. In addition to numerous maldanid and ampharetid polychaetes one animal ...

The synthetic aperture focusing technique (SAFT) is used to create focused images from ultrasound scans. SAFT has traditionally been applied only for imaging in a single medium, but the recently introduced phase shift migration (PSM) algorithm has expanded the use of SAFT to multilayer structures. In this article we present a similar focusing algorithm called multi-layer omega-k (MULOK), which ...

The red-listed, amphi-Atlantic sedge Carex rufina is highly specialized to certain alpine snowbeds, and threatened by current changes in snow cover duration and moisture conditions. Here we address its range-wide genetic diversity, history, and conservation using amplified fragment length polymorphisms (AFLPs). Despite extensive primer testing, we detected very low overall diversity (4.1% polymorphic ...

2011 is the Nansen-Amundsen Year in Norway. This year celebrate two anniversaries with great significance for Norway. It is 150 years since the birth of Fritdjof Nansen and 100 years since Roald Amundsen, accompanied by four of his men, arrived as the first at the South Pole. During this year several new exhibitions has been made and displayed in different museums in Norway. The article surveys the ...

The recovery of sea eagle Haliaeetus spp. populations in the temperate northern hemisphere in the closing decades of the 20th century is one of the great conservation success stories of recent times, but the re-establishment of these apex predators in marine systems has had consequences for seabirds. Sea eagles affect seabirds both directly (by taking adults and offspring and by inducing potentially ...

Animals with color vision use color information in intra- and interspecific communication, which in turn may drive the evolution of conspicuous colored body traits via natural and sexual selection. A recent study found that the transparent wings of small flies and wasps in lower-reflectance light environments display vivid and stable structural color patterns, called “wing interference patterns” ...
