Indiscriminately Loving Sticklebacks. A test of assortative mate preferences between two morphologically diverged parapatric populations of threespine stickleback (Gasterosteus aculeatus L.) concerning pelvic reduction
(The University of Bergen, 2013-06-07)
Two parapatric populations in western Norway in which one have completely reduced its pelvic complex are tested for assortative mating being an important mechanism in maintaining barriers keeping them from mixing in ...
Catch-and-release of Atlantic cod (Gadus morhua): post-release behaviour of acoustically pretagged fish in a natural marine environment
(NRC Research Press, 2014-10-07)
Studying the sublethal effects of catch-and-release (C&R) is challenging, as there are several potential sources of bias. For example, if behavioural alterations immediately after the release event are to be studied, ...
Deep vision: An in-trawl stereo camera makes a step forward in monitoring the pelagic community
Ecosystem surveys are carried out annually in the Barents Sea by Russia and Norway to monitor the spatial distribution of ecosystem components and to study population dynamics. One component of the survey is mapping the ...
Macrozooplankton as feed source for farmed fish - growth, product quality and safety
(The University of BergenInstitute of Marine Research, 2006-12-14)
Responses of tundra plants to experimental warming : meta-analysis of the international tundra experiment
(Ecological Society of America, 1999)
The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using a common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ...
Re-sampling in beach- and sand dune communities at South West Karmøy - 2008. Some comparisons and interpretations.
(The University of Bergen, 2009-06-02)
Sandy beaches with accompanying immature dunes as well as mature sand dunes are regarded a rare biotope in Norway. The localities of this survey are situated at the south west coast of Karmøy. As a former resident of the ...
Holocene mean July temperature and winter precipitation in western Norway inferred from palynological and glaciological lake-sediment proxies
Reconstructions of mean July temperature (Tjul) and winter precipitation (Pw) for the last 11/500 years on the Folgefonna peninsula are presented. Tjul was reconstructed using pollen-climate transfer functions and Pw was ...
Predicting abundance, species richness and assemblages of woodland snails using environmental variables
(The University of Bergen, 2003)
The abundance and diversity of woodland snails (Gastropoda: Pulmonata) were investigated in a large-scale study in Geitaknottane Nature Reserve in Kvam County (Norway). Snails were collected in 132 squares (50 X 50 meters) ...
Microbial winter and spring bloom dynamics in a high Arctic fjord
(The University of Bergen and University Centre in Svalbard, UNIS, 2014-06-02)
Knowledge of the seasonal dynamics within the Arctic marine microbial network is scarce, particularly during the polar night period. The abundances of different microbial groups in Adventfjorden, Svalbard were investigated ...
Foraging ecology and learning. Adaptive behavioural strategies and the value of information
(The University of Bergen, 2006-12-12)
All animals face the challenge of acquiring resources for growth, survival, and reproduction. In environments that vary in time and space, foragers need to make apparently complex foraging decisions on which prey to ...
