Predicting and assessing climate-change impacts on the population dynamics of alpine and lowland forbs
(The University of Bergen, 2015-05-29)
<p>Background and aims: Global climate change is already affecting plant species worldwide. The global rise in temperatures and regional changes in precipitation are predicted to continue throughout the century. Therefore, ...
The systematics of Cephalaspidea (Mollusca: gastropods) revisited, with a study on the diversity of deep sea Philinidae sensu lato from the West Pacific
(The University of Bergen, 2013-11-26)
The Cephalaspidea are the second most diverse marine clade of the Euthyneura gastropods, after the Nudipleura with many groups still known largely from shells or little anatomical data. These marine snails occur worldwide ...

Investigation of crustaceans from shelf areas in the Gulf of Guinea, with special emphasis on Brachyura
(The University of Bergen, 2009)
Crustacean abundance on continental shelves off Nigeria, Cameroon and Gabon in the Gulf of Guinea was investigated in this study. Quantitative data was sampled with a 0.1 m² Van Veen grab during a survey with RV Dr. Fridtjof ...
Morphological and functional modifications of the gastrointestinal tract during metamorphosis in Atlantic halibut (Hippoglossus hippoglossus)
(The University of Bergen, 2014-04-23)
<p>Metamorphosis in flatfish is the transition from a symmetrical larva to an asymmetrical juvenile stage, allowing the organism to utilize new resources in a different habitat and thus providing an evolutionary advantage. ...

Seismic shooting with airguns has been conducted continuously in the North Sea for about 40 years. In the past two decades there has been conflicts of interest between Norwegian industrial trawlers fishing for sandeel and ...
Lifespan extension in a semelparous chordate occurs via developmental growth arrest just prior to meiotic entry
It is proposed that the ageing process is linked to signaling from the germline such that the rate of ageing can be adjusted to the state of the reproductive system, allowing these two processes to co-evolve. Mechanistic ...
