Distribution of overwintering Calanus in the North Norwegian Sea.
(Journal article; Peer reviewed; Tidsskriftartikkel, 2006-07-25)
During winter 2003 and 2004, zooplankton and hydrographic data were collected in the northern parts of the Norwegian Sea (68–72º N, 8–17º E) west of the Norwegian shelf break at depths down to 1800 m. The results cover both inter and intra annual changes of hydrography and distribution of Calanus spp. For the whole survey area, average seawater temperature down to 1000mwas higher in 2004 than ...
Do the fastest sperm within an ejaculate swim faster in subordinate than in dominant males of Arctic char?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006)
Theoretical models predict that subordinate males should have higher sperm velocity to compensate for their disadvantaged mating role and because they experience sperm competition more frequently than dominant males. Differences in mean velocity between sperm of dominants and subordinates in the predicted direction are also documented for a few species, including the Arctic char, Salvelinus alpinus ...
On the numerous concepts in invasion biology
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006-01-20)
The study of biological invasions has triggered the production of a diversity of concepts. The terminology has, however, often been applied inconsistently and inaccurately. This article lists and assesses the most commonly used terms and concepts in invasion ecology. In each case the most coherent definition and use is suggested.
