Carbon Dynamics in Northern Marginal Seas
The marginal seas have, despite their relatively small area, an important role in the global carboncycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production ...
Microbial ecology in deep granitic groundwater - activity and impact of viruses
The deep subsurface environments in granitic rock can be studied and sampled at the Äspö hard rock laboratory (HRL) close to Oskarshamn in Sweden. Here, the groundwater is anaerobic and total counts give numbers of 104 to ...
Does fish health matter? The Utility of Biomarkers in Fish for Environmental Assessment
Two common strategies to assess exposure to environmental toxicants are to measure chemical concentrations in the environment and to examine the presence of certain species that are known to be sensitive to pollution. The ...

Ecological genetics of inbreeding, outbreeding and immunocompetence in Ranid frogs
Using artificial fertilization, I crossed frogs from different populations to evaluate fitness consequences for the offspring from an inbreeding-outbreeding perspective, and to evaluate quantitative genetic effects on ...
The evolution of flat periwinkles Littorina fabalis and L. obtusata emhasizing mitochondrial introgression and restricted recombination
The evolution of species takes in general very long time and different mechanisms are likely to operate during the various stages of this process. Accordingly speciation should be studied at different levels of species ...
Growth hormone and somatolactin function during sexual maturation of female Atlantic salmon
Background and aims: The growth hormone-insulin-like growth factor I (GH-IGF-I) system is known to act during sexual maturation of female salmonids, but the specific roles are not known. Somatolactin (SL) is a pituitary ...
B-box Proteins in Light-regulated Development in Arabidopsis
COP1 and HY5 are two key regulators of light signaling in plants. Proteins interacting with either could therefore be important regulators of light-dependent development. Previous yeast two-hybrid screens, using COP1 or ...
August Holmbergs byggnadslära
(Nordiska museets förlag, 2006)
Kunskapen om den folkliga träbyggnadskonsten som traderades från en generation till nästa återfinner vi inte i byggnadsläror och handböcker. Den har följt timmermannen och hantverkaren. Men i Nordiska museets arkiv ...
Morphological antipredator adaptations in water fleas
Some Bosmina and Daphnia species have the ability to develop extreme morphological antipredator defences, such as long antennules, high carapaces and helmets. The relative sizes of these plastic traits may differ substantially ...
