Tree thinking cannot taken for granted: challenges for teaching phylogenetics
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008-02-05)
Tree thinking is an integral part of modern
evolutionary biology, and a necessary precondition for
phylogenetics and comparative analyses. Tree thinking has
during the 20th century largely replaced group thinking,
developmental thinking and anthropocentricism in biology.
Unfortunately, however, this does not imply that tree
thinking can be taken for granted. The findings reported
here indicate ...
Complete DNA sequences of the plastid genomes of two parasitic flowering plant species, Cuscuta reflexa and Cuscuta gronovii
(Journal article; Tidsskriftartikkel; Peer reviewed, 2007-08-22)
Background: The holoparasitic plant genus Cuscuta comprises species with photosynthetic capacity and
functional chloroplasts as well as achlorophyllous and intermediate forms with restricted photosynthetic activity
and degenerated chloroplasts. Previous data indicated significant differences with respect to the plastid genome
coding capacity in different Cuscuta species that could correlate with ...

A mitogenomic approach to the taxonomy of pollocks. Theragra chalcogramma and T. finnmarchica represent one single species
(Journal article; Tidsskriftartikkel; Peer reviewed, 2007-06-07)
Background:
The walleye pollock (Theragra chalcogramma) and Norwegian pollock (T. finnmarchica) are confined to the North Pacific and North Atlantic Oceans, respectively, and considered as distinct species within the family Gadidae. We have determined the complete mtDNA nucleotide sequence of two specimens of Norwegian pollock and compared the sequences to that of 10 specimens of walleye pollock ...

Nomadic pastoralism in the Aru basin of Tibet’s Chang Tang.
(Journal article; Peer reviewed; Tidsskriftartikkel, 2004)
Nomadic pastoralists live at the northern extent of human habitation within the ca. 5000 m elevation Aru basin, in the nortwestern part of the Chang Tang Nature Preserve, Tibet. These nomads herd primarily sheep and goats, a lesser number of yaks, and a few horses. Goats are increasing in importance because of the value of cashmere wool in national and international markets. Although sheep wool ...

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 ...
