The emotion system promotes diversity and evolvability
(Royal Society Publishing, 2014-08-06)
Studies on the relationship between the optimal phenotype and its environment have had limited focus on genotype-to-phenotype pathways and their evolutionary consequences. Here, we study how multi-layered trait architecture ...
Characterization of the 18s rRNA gene for designing universal eukaryote specific primers
High throughput sequencing technology has great promise for biodiversity studies. However, an underlying assumption is that the primers used in these studies are universal for the prokaryotic or eukaryotic groups of ...
The environmental impact of the Minoan eruption of Santorini (Thera): statistical analysis of palaeoecological data from Golbisar, southwest Turkey
A tephra layer originating from the mid-second millennium BC (3300 14C yr BP) ‘Minoan’ eruption of Santorini (or Thera) in the Aegean has been found in lake sediments at G6lhisar in southwest Turkey. Microstratigraphic ...
Microbial communities and processes in ice-covered Arctic waters of the northwestern Fram Strait (75 to 80° N) during the vernal pre-bloom phase
Marine microbial communities have been little studied in Arctic waters, especially during the winter–spring transition before the development of extensive phytoplankton blooms. This study investigated microbial plankton ...
Response to comment on “Dispersal limitations matter for microbial morphospecies”
(American Association for the Advancement of Science, 2007)
Pither argues that the relationship we found between regional species-richness maxima and modal lake-pH is expected because both values are constrained by the regional pH range and therefore cannot be interpreted as a ...
Oppfattelse og berbeidelse av emosjonelle uttrykk hos mennesker - et evolusjonært perspektiv på asymmetriske ansiktsuttrykk
(The University of Bergen, 2000)
Life-history implications of the allometric scaling of growth
Several phenomenological descriptions, such as the von Bertalanffy growth model, have been widely used to describe size-at-age and individual growth across a diverse range of organisms. However, for modelling life histories, ...
Spatial dynamics of the bearded goby and its key fish predators off Namibia vary with climate and oxygen availability
Hypoxia [O2 < 2.0 mL L−1 (87 μmol kg−1)] and severely hypoxic water masses [O2 < 0.5 mL L−1 (21.8 μmol kg−1)] are increasing in coastal marine ecosystems due to eutrophication and warming. Here, we investigate the response ...
Evolution of temperature optimum in Thermotogaceae and the prediction of trait values of uncultured organisms
(Springer Link, 2011-06-03)
Quantitative characterization of the mode and rate of phenotypic evolution is rarely applied to prokaryotes. Here, we present an analysis of temperature optimum (Topt) evolution in the thermophilic family Thermotogaceae, which ...
Separating blue whiting (Micromesistius poutassou Risso, 1826) from myctophid targets using multi-frequency methods
(The University of Bergen, 2008)
Blue whiting (Micromesistius poutassou Risso, 1826) is a physoclists species, widely distributed in the Barents Sea, Norwegian Sea and Mediterranean Sea. They appear on the continental slope and shelf, in high concentration ...
